The order is library defaults found in [lib/defaults.js](https://github.com/axios/axios/blob/master/lib/defaults/index.js#L28), then `defaults` property of the instance, and finally `config` argument for the request. The latter will take precedence over the former. Here's an example. + +```js +// Create an instance using the config defaults provided by the library +// At this point the timeout config value is `0` as is the default for the library +const instance = axios.create(); + +// Override timeout default for the library +// Now all requests using this instance will wait 2.5 seconds before timing out +instance.defaults.timeout = 2500; + +// Override timeout for this request as it's known to take a long time +instance.get('/longRequest', { + timeout: 5000 +}); +``` + +## Interceptors + +You can intercept requests or responses before they are handled by `then` or `catch`. + +```js +// Add a request interceptor +axios.interceptors.request.use(function (config) { + // Do something before request is sent + return config; + }, function (error) { + // Do something with request error + return Promise.reject(error); + }); + +// Add a response interceptor +axios.interceptors.response.use(function (response) { + // Any status code that lie within the range of 2xx cause this function to trigger + // Do something with response data + return response; + }, function (error) { + // Any status codes that falls outside the range of 2xx cause this function to trigger + // Do something with response error + return Promise.reject(error); + }); +``` + +If you need to remove an interceptor later you can. + +```js +const myInterceptor = axios.interceptors.request.use(function () {/*...*/}); +axios.interceptors.request.eject(myInterceptor); +``` + +You can also clear all interceptors for requests or responses. +```js +const instance = axios.create(); +instance.interceptors.request.use(function () {/*...*/}); +instance.interceptors.request.clear(); // Removes interceptors from requests +instance.interceptors.response.use(function () {/*...*/}); +instance.interceptors.response.clear(); // Removes interceptors from responses +``` + +You can add interceptors to a custom instance of axios. + +```js +const instance = axios.create(); +instance.interceptors.request.use(function () {/*...*/}); +``` + +When you add request interceptors, they are presumed to be asynchronous by default. This can cause a delay +in the execution of your axios request when the main thread is blocked (a promise is created under the hood for +the interceptor and your request gets put on the bottom of the call stack). If your request interceptors are synchronous you can add a flag +to the options object that will tell axios to run the code synchronously and avoid any delays in request execution. + +```js +axios.interceptors.request.use(function (config) { + config.headers.test = 'I am only a header!'; + return config; +}, null, { synchronous: true }); +``` + +If you want to execute a particular interceptor based on a runtime check, +you can add a `runWhen` function to the options object. The interceptor will not be executed **if and only if** the return +of `runWhen` is `false`. The function will be called with the config +object (don't forget that you can bind your own arguments to it as well.) This can be handy when you have an +asynchronous request interceptor that only needs to run at certain times. + +```js +function onGetCall(config) { + return config.method === 'get'; +} +axios.interceptors.request.use(function (config) { + config.headers.test = 'special get headers'; + return config; +}, null, { runWhen: onGetCall }); +``` + +### Multiple Interceptors + +Given you add multiple response interceptors +and when the response was fulfilled +- then each interceptor is executed +- then they are executed in the order they were added +- then only the last interceptor's result is returned +- then every interceptor receives the result of its predecessor +- and when the fulfillment-interceptor throws + - then the following fulfillment-interceptor is not called + - then the following rejection-interceptor is called + - once caught, another following fulfill-interceptor is called again (just like in a promise chain). + +Read [the interceptor tests](./test/specs/interceptors.spec.js) for seeing all this in code. + +## Error Types + +There are many different axios error messages that can appear that can provide basic information about the specifics of the error and where opportunities may lie in debugging. + +The general structure of axios errors is as follows: +| Property | Definition | +| -------- | ---------- | +| message | A quick summary of the error message and the status it failed with. | +| name | This defines where the error originated from. For axios, it will always be an 'AxiosError'. | +| stack | Provides the stack trace of the error. | +| config | An axios config object with specific instance configurations defined by the user from when the request was made | +| code | Represents an axios identified error. The table below lists out specific definitions for internal axios error. | +| status | HTTP response status code. See [here](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes) for common HTTP response status code meanings. + +Below is a list of potential axios identified error +| Code | Definition | +| -------- | ---------- | +| ERR_BAD_OPTION_VALUE | Invalid or unsupported value provided in axios configuration. | +| ERR_BAD_OPTION | Invalid option provided in axios configuration. | +| ECONNABORTED | Request timed out due to exceeding timeout specified in axios configuration. | +| ETIMEDOUT | Request timed out due to exceeding default axios timelimit. | +| ERR_NETWORK | Network-related issue. +| ERR_FR_TOO_MANY_REDIRECTS | Request is redirected too many times; exceeds max redirects specified in axios configuration. +| ERR_DEPRECATED | Deprecated feature or method used in axios. +| ERR_BAD_RESPONSE | Response cannot be parsed properly or is in an unexpected format. +| ERR_BAD_REQUEST | Requested has unexpected format or missing required parameters. | +| ERR_CANCELED | Feature or method is canceled explicitly by the user. +| ERR_NOT_SUPPORT | Feature or method not supported in the current axios environment. +| ERR_INVALID_URL | Invalid URL provided for axios request. + +## Handling Errors + +the default behavior is to reject every response that returns with a status code that falls out of the range of 2xx and treat it as an error. + +```js +axios.get('/user/12345') + .catch(function (error) { + if (error.response) { + // The request was made and the server responded with a status code + // that falls out of the range of 2xx + console.log(error.response.data); + console.log(error.response.status); + console.log(error.response.headers); + } else if (error.request) { + // The request was made but no response was received + // `error.request` is an instance of XMLHttpRequest in the browser and an instance of + // http.ClientRequest in node.js + console.log(error.request); + } else { + // Something happened in setting up the request that triggered an Error + console.log('Error', error.message); + } + console.log(error.config); + }); +``` + +Using the `validateStatus` config option, you can override the default condition (status >= 200 && status < 300) and define HTTP code(s) that should throw an error. + +```js +axios.get('/user/12345', { + validateStatus: function (status) { + return status < 500; // Resolve only if the status code is less than 500 + } +}) +``` + +Using `toJSON` you get an object with more information about the HTTP error. + +```js +axios.get('/user/12345') + .catch(function (error) { + console.log(error.toJSON()); + }); +``` + +## Cancellation + +### AbortController + +Starting from `v0.22.0` Axios supports AbortController to cancel requests in fetch API way: + +```js +const controller = new AbortController(); + +axios.get('/foo/bar', { + signal: controller.signal +}).then(function(response) { + //... +}); +// cancel the request +controller.abort() +``` + +### CancelToken `👎deprecated` + +You can also cancel a request using a *CancelToken*. + +> The axios cancel token API is based on the withdrawn [cancellable promises proposal](https://github.com/tc39/proposal-cancelable-promises). + +> This API is deprecated since v0.22.0 and shouldn't be used in new projects + +You can create a cancel token using the `CancelToken.source` factory as shown below: + +```js +const CancelToken = axios.CancelToken; +const source = CancelToken.source(); + +axios.get('/user/12345', { + cancelToken: source.token +}).catch(function (thrown) { + if (axios.isCancel(thrown)) { + console.log('Request canceled', thrown.message); + } else { + // handle error + } +}); + +axios.post('/user/12345', { + name: 'new name' +}, { + cancelToken: source.token +}) + +// cancel the request (the message parameter is optional) +source.cancel('Operation canceled by the user.'); +``` + +You can also create a cancel token by passing an executor function to the `CancelToken` constructor: + +```js +const CancelToken = axios.CancelToken; +let cancel; + +axios.get('/user/12345', { + cancelToken: new CancelToken(function executor(c) { + // An executor function receives a cancel function as a parameter + cancel = c; + }) +}); + +// cancel the request +cancel(); +``` + +> **Note:** you can cancel several requests with the same cancel token/abort controller. +> If a cancellation token is already cancelled at the moment of starting an Axios request, then the request is cancelled immediately, without any attempts to make a real request. + +> During the transition period, you can use both cancellation APIs, even for the same request: + +## Using `application/x-www-form-urlencoded` format + +### URLSearchParams + +By default, axios serializes JavaScript objects to `JSON`. To send data in the [`application/x-www-form-urlencoded` format](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST) instead, you can use the [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) API, which is [supported](http://www.caniuse.com/#feat=urlsearchparams) in the vast majority of browsers,and [ Node](https://nodejs.org/api/url.html#url_class_urlsearchparams) starting with v10 (released in 2018). + +```js +const params = new URLSearchParams({ foo: 'bar' }); +params.append('extraparam', 'value'); +axios.post('/foo', params); +``` + +### Query string (Older browsers) + +For compatibility with very old browsers, there is a [polyfill](https://github.com/WebReflection/url-search-params) available (make sure to polyfill the global environment). + +Alternatively, you can encode data using the [`qs`](https://github.com/ljharb/qs) library: + +```js +const qs = require('qs'); +axios.post('/foo', qs.stringify({ 'bar': 123 })); +``` + +Or in another way (ES6), + +```js +import qs from 'qs'; +const data = { 'bar': 123 }; +const options = { + method: 'POST', + headers: { 'content-type': 'application/x-www-form-urlencoded' }, + data: qs.stringify(data), + url, +}; +axios(options); +``` + +### Older Node.js versions + +For older Node.js engines, you can use the [`querystring`](https://nodejs.org/api/querystring.html) module as follows: + +```js +const querystring = require('querystring'); +axios.post('https://something.com/', querystring.stringify({ foo: 'bar' })); +``` + +You can also use the [`qs`](https://github.com/ljharb/qs) library. + +> **Note**: The `qs` library is preferable if you need to stringify nested objects, as the `querystring` method has [known issues](https://github.com/nodejs/node-v0.x-archive/issues/1665) with that use case. + +### 🆕 Automatic serialization to URLSearchParams + +Axios will automatically serialize the data object to urlencoded format if the content-type header is set to "application/x-www-form-urlencoded". + +```js +const data = { + x: 1, + arr: [1, 2, 3], + arr2: [1, [2], 3], + users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}], +}; + +await axios.postForm('https://postman-echo.com/post', data, + {headers: {'content-type': 'application/x-www-form-urlencoded'}} +); +``` + +The server will handle it as: + +```js + { + x: '1', + 'arr[]': [ '1', '2', '3' ], + 'arr2[0]': '1', + 'arr2[1][0]': '2', + 'arr2[2]': '3', + 'arr3[]': [ '1', '2', '3' ], + 'users[0][name]': 'Peter', + 'users[0][surname]': 'griffin', + 'users[1][name]': 'Thomas', + 'users[1][surname]': 'Anderson' + } +```` + +If your backend body-parser (like `body-parser` of `express.js`) supports nested objects decoding, you will get the same object on the server-side automatically + +```js + var app = express(); + + app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies + + app.post('/', function (req, res, next) { + // echo body as JSON + res.send(JSON.stringify(req.body)); + }); + + server = app.listen(3000); +``` + +## Using `multipart/form-data` format + +### FormData + +To send the data as a `multipart/formdata` you need to pass a formData instance as a payload. +Setting the `Content-Type` header is not required as Axios guesses it based on the payload type. + +```js +const formData = new FormData(); +formData.append('foo', 'bar'); + +axios.post('https://httpbin.org/post', formData); +``` + +In node.js, you can use the [`form-data`](https://github.com/form-data/form-data) library as follows: + +```js +const FormData = require('form-data'); + +const form = new FormData(); +form.append('my_field', 'my value'); +form.append('my_buffer', new Buffer(10)); +form.append('my_file', fs.createReadStream('/foo/bar.jpg')); + +axios.post('https://example.com', form) +``` + +### 🆕 Automatic serialization to FormData + +Starting from `v0.27.0`, Axios supports automatic object serialization to a FormData object if the request `Content-Type` +header is set to `multipart/form-data`. + +The following request will submit the data in a FormData format (Browser & Node.js): + +```js +import axios from 'axios'; + +axios.post('https://httpbin.org/post', {x: 1}, { + headers: { + 'Content-Type': 'multipart/form-data' + } +}).then(({data}) => console.log(data)); +``` + +In the `node.js` build, the ([`form-data`](https://github.com/form-data/form-data)) polyfill is used by default. + +You can overload the FormData class by setting the `env.FormData` config variable, +but you probably won't need it in most cases: + +```js +const axios = require('axios'); +var FormData = require('form-data'); + +axios.post('https://httpbin.org/post', {x: 1, buf: new Buffer(10)}, { + headers: { + 'Content-Type': 'multipart/form-data' + } +}).then(({data}) => console.log(data)); +``` + +Axios FormData serializer supports some special endings to perform the following operations: + +- `{}` - serialize the value with JSON.stringify +- `[]` - unwrap the array-like object as separate fields with the same key + +> **Note**: unwrap/expand operation will be used by default on arrays and FileList objects + +FormData serializer supports additional options via `config.formSerializer: object` property to handle rare cases: + +- `visitor: Function` - user-defined visitor function that will be called recursively to serialize the data object +to a `FormData` object by following custom rules. + +- `dots: boolean = false` - use dot notation instead of brackets to serialize arrays and objects; + +- `metaTokens: boolean = true` - add the special ending (e.g `user{}: '{"name": "John"}'`) in the FormData key. +The back-end body-parser could potentially use this meta-information to automatically parse the value as JSON. + +- `indexes: null|false|true = false` - controls how indexes will be added to unwrapped keys of `flat` array-like objects + + - `null` - don't add brackets (`arr: 1`, `arr: 2`, `arr: 3`) + - `false`(default) - add empty brackets (`arr[]: 1`, `arr[]: 2`, `arr[]: 3`) + - `true` - add brackets with indexes (`arr[0]: 1`, `arr[1]: 2`, `arr[2]: 3`) + +Let's say we have an object like this one: + +```js +const obj = { + x: 1, + arr: [1, 2, 3], + arr2: [1, [2], 3], + users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}], + 'obj2{}': [{x:1}] +}; +``` + +The following steps will be executed by the Axios serializer internally: + +```js +const formData = new FormData(); +formData.append('x', '1'); +formData.append('arr[]', '1'); +formData.append('arr[]', '2'); +formData.append('arr[]', '3'); +formData.append('arr2[0]', '1'); +formData.append('arr2[1][0]', '2'); +formData.append('arr2[2]', '3'); +formData.append('users[0][name]', 'Peter'); +formData.append('users[0][surname]', 'Griffin'); +formData.append('users[1][name]', 'Thomas'); +formData.append('users[1][surname]', 'Anderson'); +formData.append('obj2{}', '[{"x":1}]'); +``` + +Axios supports the following shortcut methods: `postForm`, `putForm`, `patchForm` +which are just the corresponding http methods with the `Content-Type` header preset to `multipart/form-data`. + +## Files Posting + +You can easily submit a single file: + +```js +await axios.postForm('https://httpbin.org/post', { + 'myVar' : 'foo', + 'file': document.querySelector('#fileInput').files[0] +}); +``` + +or multiple files as `multipart/form-data`: + +```js +await axios.postForm('https://httpbin.org/post', { + 'files[]': document.querySelector('#fileInput').files +}); +``` + +`FileList` object can be passed directly: + +```js +await axios.postForm('https://httpbin.org/post', document.querySelector('#fileInput').files) +``` + +All files will be sent with the same field names: `files[]`. + +## 🆕 HTML Form Posting (browser) + +Pass HTML Form element as a payload to submit it as `multipart/form-data` content. + +```js +await axios.postForm('https://httpbin.org/post', document.querySelector('#htmlForm')); +``` + +`FormData` and `HTMLForm` objects can also be posted as `JSON` by explicitly setting the `Content-Type` header to `application/json`: + +```js +await axios.post('https://httpbin.org/post', document.querySelector('#htmlForm'), { + headers: { + 'Content-Type': 'application/json' + } +}) +``` + +For example, the Form + +```html +
+ + + + + + + + + +
+``` + +will be submitted as the following JSON object: + +```js +{ + "foo": "1", + "deep": { + "prop": { + "spaced": "3" + } + }, + "baz": [ + "4", + "5" + ], + "user": { + "age": "value2" + } +} +```` + +Sending `Blobs`/`Files` as JSON (`base64`) is not currently supported. + +## 🆕 Progress capturing + +Axios supports both browser and node environments to capture request upload/download progress. +The frequency of progress events is forced to be limited to `3` times per second. + +```js +await axios.post(url, data, { + onUploadProgress: function (axiosProgressEvent) { + /*{ + loaded: number; + total?: number; + progress?: number; // in range [0..1] + bytes: number; // how many bytes have been transferred since the last trigger (delta) + estimated?: number; // estimated time in seconds + rate?: number;

+ estimated?: number; + rate?: number; // download speed in bytes + download: true; // download sign + }*/ + } +}); +``` + +You can also track stream upload/download progress in node.js: + +```js +const {data} = await axios.post(SERVER_URL, readableStream, { + onUploadProgress: ({progress}) => { + console.log((progress * 100).toFixed(2)); + }, + + headers: { + 'Content-Length': contentLength + }, + + maxRedirects: 0 // avoid buffering the entire stream +}); +```` + +> **Note:** +> Capturing FormData upload progress is not currently supported in node.js environments. + +> **⚠️ Warning** +> It is recommended to disable redirects by setting maxRedirects: 0 to upload the stream in the **node.js** environment, +> as follow-redirects package will buffer the entire stream in RAM without following the "backpressure" algorithm. + + +## 🆕 Rate limiting + +Download and upload rate limits can only be set for the http adapter (node.js): + +```js +const {data} = await axios.post(LOCAL_SERVER_URL, myBuffer, { + onUploadProgress: ({progress, rate}) => { + console.log(`Upload [${(progress*100).toFixed(2)}%]: ${(rate / 1024).toFixed(2)}KB/s`) + }, + + maxRate: [100 * 1024], // 100KB/s limit +}); +``` + +## 🆕 AxiosHeaders + +Axios has its own `AxiosHeaders` class to manipulate headers using a Map-like API that guarantees caseless work. +Although HTTP is case-insensitive in headers, Axios will retain the case of the original header for stylistic reasons +and for a workaround when servers mistakenly consider the header's case. +The old approach of directly manipulating headers object is still available, but deprecated and not recommended for future usage. + +### Working with headers + +An AxiosHeaders object instance can contain different types of internal values. that control setting and merging logic. +The final headers object with string values is obtained by Axios by calling the `toJSON` method. + +> Note: By JSON here we mean an object consisting only of string values intended to be sent over the network. + +The header value can be one of the following types: +- `string` - normal string value that will be sent to the server +- `null` - skip header when rendering to JSON +- `false` - skip header when rendering to JSON, additionally indicates that `set` method must be called with `rewrite` option set to `true` + to overwrite this value (Axios uses this internally to allow users to opt out of installing certain headers like `User-Agent` or `Content-Type`) +- `undefined` - value is not set + +> Note: The header value is considered set if it is not equal to undefined. + +The headers object is always initialized inside interceptors and transformers: + +```ts + axios.interceptors.request.use((request: InternalAxiosRequestConfig) => { + request.headers.set('My-header', 'value'); + + request.headers.set({ + "My-set-header1": "my-set-value1", + "My-set-header2": "my-set-value2" + }); + + request.headers.set('User-Agent', false); // disable subsequent setting the header by Axios + + request.headers.setContentType('text/plain'); + + request.headers['My-set-header2'] = 'newValue' // direct access is deprecated + + return request; + } + ); +```` + +You can iterate over an `AxiosHeaders` instance using a `for...of` statement: + +````js +const headers = new AxiosHeaders({ + foo: '1', + bar: '2', + baz: '3' +}); + +for(const [header, value] of headers) { + console.log(header, value); +} + +// foo 1 +// bar 2 +// baz 3 +```` + +### new AxiosHeaders(headers?) + +Constructs a new `AxiosHeaders` instance. + +``` +constructor(headers?: RawAxiosHeaders | AxiosHeaders | string);

By default, it will be used if `xhr` and `http` adapters are not available in the build, +or not supported by the environment. +To use it by default, it must be selected explicitly: + +```js +const {data} = axios.get(url, { + adapter: 'fetch' // by default ['xhr', 'http', 'fetch'] +}) +``` + +You can create a separate instance for this: + +```js +const fetchAxios = axios.create({ + adapter: 'fetch' +}); + +const {data} = fetchAxios.get(url); +``` + +The adapter supports the same functionality as `xhr` adapter, **including upload and download progress capturing**. +Also, it supports additional response types such as `stream` and `formdata` (if supported by the environment). + +## Semver + +Until axios reaches a `1.0` release, breaking changes will be released with a new minor version. For example `0.5.1`, and `0.5.4` will have the same API, but `0.6.0` will have breaking changes. + +## Promises + +axios depends on a native ES6 Promise implementation to be [supported](https://caniuse.com/promises). +If your environment doesn't support ES6 Promises, you can [polyfill](https://github.com/jakearchibald/es6-promise). + +## TypeScript + +axios includes [TypeScript](https://typescriptlang.org) definitions and a type guard for axios errors. + +```typescript +let user: User = null; +try { + const { data } = await axios.get('/user?ID=12345'); + user = data.userDetails; +} catch (error) { + if (axios.isAxiosError(error)) { + handleAxiosError(error); + } else { + handleUnexpectedError(error); + } +} +``` + +Because axios dual publishes with an ESM default export and a CJS `module.exports`, there are some caveats. +The recommended setting is to use `"moduleResolution": "node16"` (this is implied by `"module": "node16"`).

In other words: + +- [brace expansion](#brace-expansion) is for generating new lists +- [brace matching](#brace-matching) is for filtering existing lists + +
+More about brace expansion (click to expand) + +There are two main types of brace expansion: + +1. **lists**: which are defined using comma-separated values inside curly braces: `{a,b,c}` +2. **sequences**: which are defined using a starting value and an ending value, separated by two dots: `a{1..3}b`. Optionally, a third argument may be passed to define a "step" or increment to use: `a{1..100..10}b`. These are also sometimes referred to as "ranges". + +Here are some example brace patterns to illustrate how they work: + +**Sets** + +``` +{a,b,c} => a b c +{a,b,c}{1,2} => a1 a2 b1 b2 c1 c2 +``` + +**Sequences** + +``` +{1..9} => 1 2 3 4 5 6 7 8 9 +{4..-4} => 4 3 2 1 0 -1 -2 -3 -4 +{1..20..3} => 1 4 7 10 13 16 19 +{a..j} => a b c d e f g h i j +{j..a} => j i h g f e d c b a +{a..z..3} => a d g j m p s v y +``` + +**Combination** + +Sets and sequences can be mixed together or used along with any other strings. + +``` +{a,b,c}{1..3} => a1 a2 a3 b1 b2 b3 c1 c2 c3 +foo/{a,b,c}/bar => foo/a/bar foo/b/bar foo/c/bar +``` + +The fact that braces can be "expanded" from relatively simple patterns makes them ideal for quickly generating test fixtures, file paths, and similar use cases. + +## Brace matching + +In addition to _expansion_, brace patterns are also useful for performing regular-expression-like matching. + +For example, the pattern `foo/{1..3}/bar` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +``` + +But not: + +``` +baz/1/qux +baz/2/qux +baz/3/qux +``` + +Braces can also be combined with [glob patterns](https://github.com/jonschlinkert/micromatch) to perform more advanced wildcard matching. For example, the pattern `*/{1..3}/*` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +baz/1/qux +baz/2/qux +baz/3/qux +``` + +## Brace matching pitfalls + +Although brace patterns offer a user-friendly way of matching ranges or sets of strings, there are also some major disadvantages and potential risks you should be aware of. + +### tldr + +**"brace bombs"** + +- brace expansion can eat up a huge amount of processing resources +- as brace patterns increase _linearly in size_, the system resources required to expand the pattern increase exponentially +- users can accidentally (or intentially) exhaust your system's resources resulting in the equivalent of a DoS attack (bonus: no programming knowledge is required!) + +For a more detailed explanation with examples, see the [geometric complexity](#geometric-complexity) section. + +### The solution + +Jump to the [performance section](#performance) to see how Braces solves this problem in comparison to other libraries. + +### Geometric complexity + +At minimum, brace patterns with sets limited to two elements have quadradic or `O(n^2)` complexity. But the complexity of the algorithm increases exponentially as the number of sets, _and elements per set_, increases, which is `O(n^c)`. + +For example, the following sets demonstrate quadratic (`O(n^2)`) complexity: + +``` +{1,2}{3,4} => (2X2) => 13 14 23 24 +{1,2}{3,4}{5,6} => (2X2X2) => 135 136 145 146 235 236 245 246 +``` + +But add an element to a set, and we get a n-fold Cartesian product with `O(n^c)` complexity: + +``` +{1,2,3}{4,5,6}{7,8,9} => (3X3X3) => 147 148 149 157 158 159 167 168 169 247 248 + 249 257 258 259 267 268 269 347 348 349 357 + 358 359 367 368 369 +``` + +Now, imagine how this complexity grows given that each element is a n-tuple: + +``` +{1..100}{1..100} => (100X100) => 10,000 elements (38.4 kB) +{1..100}{1..100}{1..100} => (100X100X100) => 1,000,000 elements (5.76 MB) +``` + +Although these examples are clearly contrived, they demonstrate how brace patterns can quickly grow out of control. + +**More information** + +Interested in learning more about brace expansion? + +- [linuxjournal/bash-brace-expansion](http://www.linuxjournal.com/content/bash-brace-expansion) +- [rosettacode/Brace_expansion](https://rosettacode.org/wiki/Brace_expansion) +- [cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) + +
+ +## Performance + +Braces is not only screaming fast, it's also more accurate the other brace expansion libraries. + +### Better algorithms + +Fortunately there is a solution to the ["brace bomb" problem](#brace-matching-pitfalls): _don't expand brace patterns into an array when they're used for matching_. + +Instead, convert the pattern into an optimized regular expression.

Check out our blog post about it: [Chokidar 3: How to save 32TB of traffic every week](https://paulmillr.com/posts/chokidar-3-save-32tb-of-traffic/) + +## How? + +Chokidar does still rely on the Node.js core `fs` module, but when using +`fs.watch` and `fs.watchFile` for watching, it normalizes the events it +receives, often checking for truth by getting file stats and/or dir contents. + +On MacOS, chokidar by default uses a native extension exposing the Darwin +`FSEvents` API. This provides very efficient recursive watching compared with +implementations like `kqueue` available on most \*nix platforms. Chokidar still +does have to do some work to normalize the events received that way as well. + +On most other platforms, the `fs.watch`-based implementation is the default, which +avoids polling and keeps CPU usage down. Be advised that chokidar will initiate +watchers recursively for everything within scope of the paths that have been +specified, so be judicious about not wasting system resources by watching much +more than needed. + +## Getting started + +Install with npm: + +```sh +npm install chokidar +``` + +Then `require` and use it in your code: + +```javascript +const chokidar = require('chokidar'); + +// One-liner for current directory +chokidar.watch('.').on('all', (event, path) => { + console.log(event, path); +}); +``` + +## API + +```javascript +// Example of a more typical implementation structure + +// Initialize watcher. +const watcher = chokidar.watch('file, dir, glob, or array', { + ignored: /(^|[\/\\])\../, // ignore dotfiles + persistent: true +}); + +// Something to use when events are received. +const log = console.log.bind(console); +// Add event listeners. +watcher + .on('add', path => log(`File ${path} has been added`)) + .on('change', path => log(`File ${path} has been changed`)) + .on('unlink', path => log(`File ${path} has been removed`)); + +// More possible events. +watcher + .on('addDir', path => log(`Directory ${path} has been added`)) + .on('unlinkDir', path => log(`Directory ${path} has been removed`)) + .on('error', error => log(`Watcher error: ${error}`)) + .on('ready', () => log('Initial scan complete. Ready for changes')) + .on('raw', (event, path, details) => { // internal + log('Raw event info:', event, path, details); + }); + +// 'add', 'addDir' and 'change' events also receive stat() results as second +// argument when available: https://nodejs.org/api/fs.html#fs_class_fs_stats +watcher.on('change', (path, stats) => { + if (stats) console.log(`File ${path} changed size to ${stats.size}`); +}); + +// Watch new files. +watcher.add('new-file'); +watcher.add(['new-file-2', 'new-file-3', '**/other-file*']); + +// Get list of actual paths being watched on the filesystem +var watchedPaths = watcher.getWatched(); + +// Un-watch some files. +await watcher.unwatch('new-file*'); + +// Stop watching. +// The method is async! +watcher.close().then(() => console.log('closed')); + +// Full list of options.

Indicates whether the process +should continue to run as long as files are being watched. If set to +`false` when using `fsevents` to watch, no more events will be emitted +after `ready`, even if the process continues to run. + +#### Path filtering + +* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition) +Defines files/paths to be ignored. The whole relative or absolute path is +tested, not just filename. If a function with two arguments is provided, it +gets called twice per path - once with a single argument (the path), second +time with two arguments (the path and the +[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats) +object of that path). +* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while +instantiating the watching as chokidar discovers these file paths (before the `ready` event). +* `followSymlinks` (default: `true`). When `false`, only the +symlinks themselves will be watched for changes instead of following +the link references and bubbling events through the link's path. +* `cwd` (no default). The base directory from which watch `paths` are to be +derived. Paths emitted with events will be relative to this. +* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as +literal path names, even if they look like globs. + +#### Performance + +* `usePolling` (default: `false`). +Whether to use fs.watchFile (backed by polling), or fs.watch. If polling +leads to high CPU utilization, consider setting this to `false`. It is +typically necessary to **set this to `true` to successfully watch files over +a network**, and it may be necessary to successfully watch files in other +non-standard situations. Setting to `true` explicitly on MacOS overrides the +`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable +to true (1) or false (0) in order to override this option. +* _Polling-specific settings_ (effective when `usePolling: true`) + * `interval` (default: `100`). Interval of file system polling, in milliseconds. You may also + set the CHOKIDAR_INTERVAL env variable to override this option. + * `binaryInterval` (default: `300`). Interval of file system + polling for binary files. + ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json)) +* `useFsEvents` (default: `true` on MacOS). Whether to use the +`fsevents` watching interface if available. When set to `true` explicitly +and `fsevents` is available this supercedes the `usePolling` setting. When +set to `false` on MacOS, `usePolling: true` becomes the default. +* `alwaysStat` (default: `false`). If relying upon the +[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats) +object that may get passed with `add`, `addDir`, and `change` events, set +this to `true` to ensure it is provided even in cases where it wasn't +already available from the underlying watch events. +* `depth` (default: `undefined`). If set, limits how many levels of +subdirectories will be traversed. +* `awaitWriteFinish` (default: `false`). +By default, the `add` event will fire when a file first appears on disk, before +the entire file has been written. Furthermore, in some cases some `change` +events will be emitted while the file is being written. In some cases, +especially when watching for large files there will be a need to wait for the +write operation to finish before responding to a file creation or modification. +Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size, +holding its `add` and `change` events until the size does not change for a +configurable amount of time. The appropriate duration setting is heavily +dependent on the OS and hardware. For accurate detection this parameter should +be relatively high, making file watching much less responsive. +Use with caution. + * *`options.awaitWriteFinish` can be set to an object in order to adjust + timing params:* + * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in + milliseconds for a file size to remain constant before emitting its event. + * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval, in milliseconds. + +#### Errors + +* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files +that don't have read permissions if possible. If watching fails due to `EPERM` +or `EACCES` with this set to `true`, the errors will be suppressed silently. +* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`). +Automatically filters out artifacts that occur when using editors that use +"atomic writes" instead of writing directly to the source file. If a file is +re-added within 100 ms of being deleted, Chokidar emits a `change` event +rather than `unlink` then `add`. If the default of 100 ms does not work well +for you, you can override it by setting `atomic` to a custom value, in +milliseconds. + +### Methods & Events + +`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`: + +* `.add(path / paths)`: Add files, directories, or glob patterns for tracking. +Takes an array of strings or just one string. +* `.on(event, callback)`: Listen for an FS event. +Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`, +`raw`, `error`. +Additionally `all` is available which gets emitted with the underlying event +name and path for every event other than `ready`, `raw`, and `error`. `raw` is internal, use it carefully. +* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns. +Takes an array of strings or just one string. +* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen. +* `.getWatched()`: Returns an object representing all the paths on the file +system being watched by this `FSWatcher` instance. The object's keys are all the +directories (using absolute paths unless the `cwd` option was used), and the +values are arrays of the names of the items contained in each directory. + +## CLI + +If you need a CLI interface for your file watching, check out +[chokidar-cli](https://github.com/open-cli-tools/chokidar-cli), allowing you to +execute a command on each change, or get a stdio stream of change events. + +## Install Troubleshooting + +* `npm WARN optional dep failed, continuing fsevents@n.n.n` + * This message is normal part of how `npm` handles optional dependencies and is + not indicative of a problem. Even if accompanied by other related error messages, + Chokidar should function properly. + +* `TypeError: fsevents is not a constructor` + * Update chokidar by doing `rm -rf node_modules package-lock.json yarn.lock && npm install`, or update your dependency that uses chokidar. + +* Chokidar is producing `ENOSP` error on Linux, like this: + * `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell` + `Error: watch /home/ ENOSPC` + * This means Chokidar ran out of file handles and you'll need to increase their count by executing the following command in Terminal: + `echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p` + +## Changelog + +For more detailed changelog, see [`full_changelog.md`](.github/full_changelog.md). +- **v3.5 (Jan 6, 2021):** Support for ARM Macs with Apple Silicon.

Until node implements a catch-all event listener, this is the only way. + +However, delayed-stream still continues to emit all events it captures on the +`source`, regardless of whether you have released the delayed stream yet or +not. + +Upon creation, delayed-stream captures all `source` events and stores them in +an internal event buffer. Once `delayedStream.release()` is called, all +buffered events are emitted on the `delayedStream`, and the event buffer is +cleared. After that, delayed-stream merely acts as a proxy for the underlaying +source. + +### Error handling + +Error events on `source` are buffered / proxied just like any other events. +However, `delayedStream.create` attaches a no-op `'error'` listener to the +`source`. This way you only have to handle errors on the `delayedStream` +object, rather than in two places. + +### Buffer limits + +delayed-stream provides a `maxDataSize` property that can be used to limit +the amount of data being buffered. In order to protect you from bad `source` +streams that don't react to `source.pause()`, this feature is enabled by +default. + +## API + +### DelayedStream.create(source, [options]) + +Returns a new `delayedStream`. Available options are: + +* `pauseStream` +* `maxDataSize` + +The description for those properties can be found below. + +### delayedStream.source + +The `source` stream managed by this object. This is useful if you are +passing your `delayedStream` around, and you still want to access properties +on the `source` object. + +### delayedStream.pauseStream = true + +Whether to pause the underlaying `source` when calling +`DelayedStream.create()`. Modifying this property afterwards has no effect. + +### delayedStream.maxDataSize = 1024 * 1024 + +The amount of data to buffer before emitting an `error`. + +If the underlaying source is emitting `Buffer` objects, the `maxDataSize` +refers to bytes. + +If the underlaying source is emitting JavaScript strings, the size refers to +characters. + +If you know what you are doing, you can set this property to `Infinity` to +disable this feature. You can also modify this property during runtime. + +### delayedStream.dataSize = 0 + +The amount of data buffered so far. + +### delayedStream.readable + +An ECMA5 getter that returns the value of `source.readable`. + +### delayedStream.resume() + +If the `delayedStream` has not been released so far, `delayedStream.release()` +is called. + +In either case, `source.resume()` is called. + +### delayedStream.pause() + +Calls `source.pause()`. + +### delayedStream.pipe(dest) + +Calls `delayedStream.resume()` and then proxies the arguments to `source.pipe`. + +### delayedStream.release() + +Emits and clears all events that have been buffered up so far.

For example, you may only need and read the first 6 bytes, and the last 128 bytes, which may be an advantage in case reading the entire file would take longer. + +```js +const {makeTokenizer} = require('@tokenizer/http'); +const FileType = require('file-type'); + +const audioTrackUrl = 'https://test-audio.netlify.com/Various%20Artists%20-%202009%20-%20netBloc%20Vol%2024_%20tiuqottigeloot%20%5BMP3-V2%5D/01%20-%20Diablo%20Swing%20Orchestra%20-%20Heroines.mp3'; + +(async () => { + const httpTokenizer = await makeTokenizer(audioTrackUrl); + const fileType = await FileType.fromTokenizer(httpTokenizer); + + console.log(fileType); + //=> {ext: 'mp3', mime: 'audio/mpeg'} +})(); +``` + +Or use [`@tokenizer/s3`](https://github.com/Borewit/tokenizer-s3) to determine the file type of a file stored on [Amazon S3](https://aws.amazon.com/s3): + +```js +const FileType = require('file-type'); +const S3 = require('aws-sdk/clients/s3'); +const {makeTokenizer} = require('@tokenizer/s3'); + +(async () => { + // Initialize the S3 client + const s3 = new S3(); + + // Initialize the S3 tokenizer. + const s3Tokenizer = await makeTokenizer(s3, { + Bucket: 'affectlab', + Key: '1min_35sec.mp4' + }); + + // Figure out what kind of file it is. + const fileType = await FileType.fromTokenizer(s3Tokenizer); + console.log(fileType); +})(); +``` + +Note that only the minimum amount of data required to determine the file type is read (okay, just a bit extra to prevent too many fragmented reads). + +#### tokenizer + +Type: [`ITokenizer`](https://github.com/Borewit/strtok3#tokenizer) + +A file source implementing the [tokenizer interface](https://github.com/Borewit/strtok3#tokenizer). + +### FileType.stream(readableStream) + +Detect the file type of a readable stream. + +Returns a `Promise` which resolves to the original readable stream argument, but with an added `fileType` property, which is an object like the one returned from `FileType.fromFile()`. + +*Note:* This method is only available using Node.js. + +#### readableStream + +Type: [`stream.Readable`](https://nodejs.org/api/stream.html#stream_class_stream_readable) + +The input stream. + +### FileType.extensions + +Returns a set of supported file extensions. + +### FileType.mimeTypes + +Returns a set of supported MIME types. ## Supported file types -- [`jpg`](https://en.wikipedia.org/wiki/JPEG) -- [`png`](https://en.wikipedia.org/wiki/Portable_Network_Graphics) -- [`gif`](https://en.wikipedia.org/wiki/GIF) -- [`webp`](https://en.wikipedia.org/wiki/WebP) -- [`flif`](https://en.wikipedia.org/wiki/Free_Lossless_Image_Format) -- [`cr2`](http://fileinfo.com/extension/cr2) -- [`tif`](https://en.wikipedia.org/wiki/Tagged_Image_File_Format) -- [`bmp`](https://en.wikipedia.org/wiki/BMP_file_format) -- [`jxr`](https://en.wikipedia.org/wiki/JPEG_XR) -- [`psd`](https://en.wikipedia.org/wiki/Adobe_Photoshop#File_format) -- [`zip`](https://en.wikipedia.org/wiki/Zip_(file_format)) -- [`tar`](https://en.wikipedia.org/wiki/Tar_(computing)#File_format) -- [`rar`](https://en.wikipedia.org/wiki/RAR_(file_format)) -- [`gz`](https://en.wikipedia.org/wiki/Gzip) -- [`bz2`](https://en.wikipedia.org/wiki/Bzip2) -- [`7z`](https://en.wikipedia.org/wiki/7z) -- [`dmg`](https://en.wikipedia.org/wiki/Apple_Disk_Image) -- [`mp4`](https://en.wikipedia.org/wiki/MPEG-4_Part_14#Filename_extensions) -- [`m4v`](https://en.wikipedia.org/wiki/M4V) -- [`mid`](https://en.wikipedia.org/wiki/MIDI) -- [`mkv`](https://en.wikipedia.org/wiki/Matroska) -- [`webm`](https://en.wikipedia.org/wiki/WebM) -- [`mov`](https://en.wikipedia.org/wiki/QuickTime_File_Format) -- [`avi`](https://en.wikipedia.org/wiki/Audio_Video_Interleave) -- [`wmv`](https://en.wikipedia.org/wiki/Windows_Media_Video) -- [`mpg`](https://en.wikipedia.org/wiki/MPEG-1) -- [`mp2`](https://en.wikipedia.org/wiki/MPEG-1_Audio_Layer_II) -- [`mp3`](https://en.wikipedia.org/wiki/MP3) -- [`m4a`](https://en.wikipedia.org/wiki/MPEG-4_Part_14#.MP4_versus_.M4A) -- [`ogg`](https://en.wikipedia.org/wiki/Ogg) -- [`opus`](https://en.wikipedia.org/wiki/Opus_(audio_format)) -- [`flac`](https://en.wikipedia.org/wiki/FLAC) -- [`wav`](https://en.wikipedia.org/wiki/WAV) -- [`qcp`](https://en.wikipedia.org/wiki/QCP) -- [`amr`](https://en.wikipedia.org/wiki/Adaptive_Multi-Rate_audio_codec) -- [`pdf`](https://en.wikipedia.org/wiki/Portable_Document_Format) -- [`epub`](https://en.wikipedia.org/wiki/EPUB) +- [`jpg`](https://en.wikipedia.org/wiki/JPEG) -

All data is - // referenced by a code, which represents one or more values from the - // original input stream. All input bytes can be referenced as the same - // value as an output code. So if you didn't want any compression, you - // could more or less just output the original bytes as codes (there are - // some details to this, but it is the idea). In order to achieve - // compression, values greater then the input range (codes can be up to - // 12-bit while input only 8-bit) represent a sequence of previously seen - // inputs. The decompressor is able to build the same mapping while - // decoding, so there is always a shared common knowledge between the - // encoding and decoder, which is also important for "timing" aspects like - // how to handle variable bit width code encoding. - // - // One obvious but very important consequence of the table system is there - // is always a unique id (at most 12-bits) to map the runs. 'A' might be - // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship - // can be used for an effecient lookup strategy for the code mapping. We - // need to know if a run has been seen before, and be able to map that run - // to the output code. Since we start with known unique ids (input bytes), - // and then from those build more unique ids (table entries), we can - // continue this chain (almost like a linked list) to always have small - // integer values that represent the current byte chains in the encoder. - // This means instead of tracking the input bytes (AAAABCD) to know our - // current state, we can track the table entry for AAAABC (it is guaranteed - // to exist by the nature of the algorithm) and the next character D. - // Therefor the tuple of (table_entry, byte) is guaranteed to also be - // unique. This allows us to create a simple lookup key for mapping input - // sequences to codes (table indices) without having to store or search - // any of the code sequences. So if 'AAAA' has a table entry of 12, the - // tuple of ('AAAA', K) for any input byte K will be unique, and can be our - // key.

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - -'use strict'; - -module.exports = Transform; - -var Duplex = require('./_stream_duplex'); - -/**/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/**/ - -util.inherits(Transform, Duplex); - -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) { - return this.emit('error', new Error('write callback called multiple times')); - } - - ts.writechunk = null; - ts.writecb = null; - - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); - - cb(er); - - var rs = this._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); - } -} - -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - - Duplex.call(this, options); - - this._transformState = { - afterTransform: afterTransform.bind(this), - needTransform: false, - transforming: false, - writecb: null, - writechunk: null, - writeencoding: null - }; - - // start out asking for a readable event once data is transformed. - this._readableState.needReadable = true; - - // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - this._readableState.sync = false; - - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; - - if (typeof options.flush === 'function') this._flush = options.flush; - } - - // When the writable side finishes, then flush out anything remaining. - this.on('prefinish', prefinish); -} - -function prefinish() { - var _this = this; - - if (typeof this._flush === 'function') { - this._flush(function (er, data) { - done(_this, er, data); - }); - } else { - done(this, null, null); - } -} - -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; - -// This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. -'use strict'; - -module.exports = Transform; - -var _require$codes = require('../errors').codes, - ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED, - ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK, - ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING, - ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0; - -var Duplex = require('./_stream_duplex'); - -require('inherits')(Transform, Duplex); - -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - var cb = ts.writecb; - - if (cb === null) { - return this.emit('error', new ERR_MULTIPLE_CALLBACK()); - } - - ts.writechunk = null; - ts.writecb = null; - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); - cb(er); - var rs = this._readableState; - rs.reading = false; - - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); - } -} - -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - Duplex.call(this, options); - this._transformState = { - afterTransform: afterTransform.bind(this), - needTransform: false, - transforming: false, - writecb: null, - writechunk: null, - writeencoding: null - }; // start out asking for a readable event once data is transformed. - - this._readableState.needReadable = true; // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - - this._readableState.sync = false; - - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; - if (typeof options.flush === 'function') this._flush = options.flush; - } // When the writable side finishes, then flush out anything remaining. - - - this.on('prefinish', prefinish); -} - -function prefinish() { - var _this = this; - - if (typeof this._flush === 'function' && !this._readableState.destroyed) { - this._flush(function (er, data) { - done(_this, er, data); - }); - } else { - done(this, null, null); - } -} - -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; // This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.

All data is\n // referenced by a code, which represents one or more values from the\n // original input stream. All input bytes can be referenced as the same\n // value as an output code. So if you didn't want any compression, you\n // could more or less just output the original bytes as codes (there are\n // some details to this, but it is the idea). In order to achieve\n // compression, values greater then the input range (codes can be up to\n // 12-bit while input only 8-bit) represent a sequence of previously seen\n // inputs. The decompressor is able to build the same mapping while\n // decoding, so there is always a shared common knowledge between the\n // encoding and decoder, which is also important for \"timing\" aspects like\n // how to handle variable bit width code encoding.\n //\n // One obvious but very important consequence of the table system is there\n // is always a unique id (at most 12-bits) to map the runs. 'A' might be\n // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship\n // can be used for an effecient lookup strategy for the code mapping. We\n // need to know if a run has been seen before, and be able to map that run\n // to the output code. Since we start with known unique ids (input bytes),\n // and then from those build more unique ids (table entries), we can\n // continue this chain (almost like a linked list) to always have small\n // integer values that represent the current byte chains in the encoder.\n // This means instead of tracking the input bytes (AAAABCD) to know our\n // current state, we can track the table entry for AAAABC (it is guaranteed\n // to exist by the nature of the algorithm) and the next character D.\n // Therefor the tuple of (table_entry, byte) is guaranteed to also be\n // unique. This allows us to create a simple lookup key for mapping input\n // sequences to codes (table indices) without having to store or search\n // any of the code sequences. So if 'AAAA' has a table entry of 12, the\n // tuple of ('AAAA', K) for any input byte K will be unique, and can be our\n // key.

All data is\n // referenced by a code, which represents one or more values from the\n // original input stream. All input bytes can be referenced as the same\n // value as an output code. So if you didn't want any compression, you\n // could more or less just output the original bytes as codes (there are\n // some details to this, but it is the idea). In order to achieve\n // compression, values greater then the input range (codes can be up to\n // 12-bit while input only 8-bit) represent a sequence of previously seen\n // inputs. The decompressor is able to build the same mapping while\n // decoding, so there is always a shared common knowledge between the\n // encoding and decoder, which is also important for \"timing\" aspects like\n // how to handle variable bit width code encoding.\n //\n // One obvious but very important consequence of the table system is there\n // is always a unique id (at most 12-bits) to map the runs. 'A' might be\n // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship\n // can be used for an effecient lookup strategy for the code mapping. We\n // need to know if a run has been seen before, and be able to map that run\n // to the output code. Since we start with known unique ids (input bytes),\n // and then from those build more unique ids (table entries), we can\n // continue this chain (almost like a linked list) to always have small\n // integer values that represent the current byte chains in the encoder.\n // This means instead of tracking the input bytes (AAAABCD) to know our\n // current state, we can track the table entry for AAAABC (it is guaranteed\n // to exist by the nature of the algorithm) and the next character D.\n // Therefor the tuple of (table_entry, byte) is guaranteed to also be\n // unique. This allows us to create a simple lookup key for mapping input\n // sequences to codes (table indices) without having to store or search\n // any of the code sequences. So if 'AAAA' has a table entry of 12, the\n // tuple of ('AAAA', K) for any input byte K will be unique, and can be our\n // key.

The caller must assure this.\n 1..MAXBITS is interpreted as that code length. zero means that that\n symbol does not occur in this code.\n\n The codes are sorted by computing a count of codes for each length,\n creating from that a table of starting indices for each length in the\n sorted table, and then entering the symbols in order in the sorted\n table. The sorted table is work[], with that space being provided by\n the caller.\n\n The length counts are used for other purposes as well, i.e. finding\n the minimum and maximum length codes, determining if there are any\n codes at all, checking for a valid set of lengths, and looking ahead\n at length counts to determine sub-table sizes when building the\n decoding tables.\n */\n\n /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */\n for (len = 0; len <= MAXBITS; len++) {\n count[len] = 0;\n }\n for (sym = 0; sym < codes; sym++) {\n count[lens[lens_index + sym]]++;\n }\n\n /* bound code lengths, force root to be within code lengths */\n root = bits;\n for (max = MAXBITS; max >= 1; max--) {\n if (count[max] !== 0) { break; }\n }\n if (root > max) {\n root = max;\n }\n if (max === 0) { /* no symbols to code at all */\n //table.op[opts.table_index] = 64; //here.op = (var char)64; /* invalid code marker */\n //table.bits[opts.table_index] = 1; //here.bits = (var char)1;\n //table.val[opts.table_index++] = 0; //here.val = (var short)0;\n table[table_index++] = (1 << 24) | (64 << 16) | 0;\n\n\n //table.op[opts.table_index] = 64;\n //table.bits[opts.table_index] = 1;\n //table.val[opts.table_index++] = 0;\n table[table_index++] = (1 << 24) | (64 << 16) | 0;\n\n opts.bits = 1;\n return 0; /* no symbols, but wait for decoding to report error */\n }\n for (min = 1; min < max; min++) {\n if (count[min] !== 0) { break; }\n }\n if (root < min) {\n root = min;\n }\n\n /* check for an over-subscribed or incomplete set of lengths */\n left = 1;\n for (len = 1; len <= MAXBITS; len++) {\n left <<= 1;\n left -= count[len];\n if (left < 0) {\n return -1;\n } /* over-subscribed */\n }\n if (left > 0 && (type === CODES || max !== 1)) {\n return -1; /* incomplete set */\n }\n\n /* generate offsets into symbol table for each length for sorting */\n offs[1] = 0;\n for (len = 1; len < MAXBITS; len++) {\n offs[len + 1] = offs[len] + count[len];\n }\n\n /* sort symbols by length, by symbol order within each length */\n for (sym = 0; sym < codes; sym++) {\n if (lens[lens_index + sym] !== 0) {\n work[offs[lens[lens_index + sym]]++] = sym;\n }\n }\n\n /*\n Create and fill in decoding tables.

When you call read(), that calls _read(n) until\n// there's enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer. When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb's as it consumes chunks. If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit 'readable' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk. However,\n// a pathological inflate type of transform can cause excessive buffering\n// here. For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output. In this case, you could write a very small\n// amount of input, and end up with a very large amount of output. In\n// such a pathological inflating mechanism, there'd be no way to tell\n// the system to stop doing the transform. A single 4MB write could\n// cause the system to run out of memory.\n//\n// However, even in such a pathological case, only a single written chunk\n// would be consumed, and then the rest would wait (un-transformed) until\n// the results of the previous transformed chunk were consumed.\n'use strict';\n\nmodule.exports = Transform;\n\nvar _require$codes = require('../errors').codes,\n ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED,\n ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK,\n ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING,\n ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0;\n\nvar Duplex = require('./_stream_duplex');\n\nrequire('inherits')(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n var ts = this._transformState;\n ts.transforming = false;\n var cb = ts.writecb;\n\n if (cb === null) {\n return this.emit('error', new ERR_MULTIPLE_CALLBACK());\n }\n\n ts.writechunk = null;\n ts.writecb = null;\n if (data != null) // single equals check for both `null` and `undefined`\n this.push(data);\n cb(er);\n var rs = this._readableState;\n rs.reading = false;\n\n if (rs.needReadable || rs.length < rs.highWaterMark) {\n this._read(rs.highWaterMark);\n }\n}\n\nfunction Transform(options) {\n if (!(this instanceof Transform)) return new Transform(options);\n Duplex.call(this, options);\n this._transformState = {\n afterTransform: afterTransform.bind(this),\n needTransform: false,\n transforming: false,\n writecb: null,\n writechunk: null,\n writeencoding: null\n }; // start out asking for a readable event once data is transformed.\n\n this._readableState.needReadable = true; // we have implemented the _read method, and done the other things\n // that Readable wants before the first _read call, so unset the\n // sync guard flag.\n\n this._readableState.sync = false;\n\n if (options) {\n if (typeof options.transform === 'function') this._transform = options.transform;\n if (typeof options.flush === 'function') this._flush = options.flush;\n } // When the writable side finishes, then flush out anything remaining.\n\n\n this.on('prefinish', prefinish);\n}\n\nfunction prefinish() {\n var _this = this;\n\n if (typeof this._flush === 'function' && !this._readableState.destroyed) {\n this._flush(function (er, data) {\n done(_this, er, data);\n });\n } else {\n done(this, null, null);\n }\n}\n\nTransform.prototype.push = function (chunk, encoding) {\n this._transformState.needTransform = false;\n return Duplex.prototype.push.call(this, chunk, encoding);\n}; // This is the part where you do stuff!\n// override this function in implementation classes.\n// 'chunk' is an input chunk.\n//\n// Call `push(newChunk)` to pass along transformed output\n// to the readable side.

A single regular expression + expressing the entire pattern. This is useful in cases where you wish + to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled. +* `negate` True if the pattern is negated. +* `comment` True if the pattern is a comment. +* `empty` True if the pattern is `""`. + +### Methods + +* `makeRe` Generate the `regexp` member if necessary, and return it. + Will return `false` if the pattern is invalid. +* `match(fname)` Return true if the filename matches the pattern, or + false otherwise. +* `matchOne(fileArray, patternArray, partial)` Take a `/`-split + filename, and match it against a single row in the `regExpSet`. This + method is mainly for internal use, but is exposed so that it can be + used by a glob-walker that needs to avoid excessive filesystem calls. + +All other methods are internal, and will be called as necessary. + +### minimatch(path, pattern, options) + +Main export. Tests a path against the pattern using the options. + +```javascript +var isJS = minimatch(file, "*.js", { matchBase: true }) +``` + +### minimatch.filter(pattern, options) + +Returns a function that tests its +supplied argument, suitable for use with `Array.filter`. Example: + +```javascript +var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true})) +``` + +### minimatch.match(list, pattern, options) + +Match against the list of +files, in the style of fnmatch or glob. If nothing is matched, and +options.nonull is set, then return a list containing the pattern itself. + +```javascript +var javascripts = minimatch.match(fileList, "*.js", {matchBase: true})) +``` + +### minimatch.makeRe(pattern, options) + +Make a regular expression object from the pattern. + +## Options + +All options are `false` by default. + +### debug + +Dump a ton of stuff to stderr. + +### nobrace + +Do not expand `{a,b}` and `{1..3}` brace sets. + +### noglobstar + +Disable `**` matching against multiple folder names. + +### dot + +Allow patterns to match filenames starting with a period, even if +the pattern does not explicitly have a period in that spot. + +Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot` +is set. + +### noext + +Disable "extglob" style patterns like `+(a|b)`. + +### nocase + +Perform a case-insensitive match. + +### nonull + +When a match is not found by `minimatch.match`, return a list containing +the pattern itself if this option is set. When not set, an empty list +is returned if there are no matches. + +### matchBase + +If set, then patterns without slashes will be matched +against the basename of the path if it contains slashes. For example, +`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. + +### nocomment + +Suppress the behavior of treating `#` at the start of a pattern as a +comment. + +### nonegate + +Suppress the behavior of treating a leading `!` character as negation. + +### flipNegate + +Returns from negate expressions the same as if they were not negated. +(Ie, true on a hit, false on a miss.) + +### partial + +Compare a partial path to a pattern. As long as the parts of the path that +are present are not contradicted by the pattern, it will be treated as a +match. This is useful in applications where you're walking through a +folder structure, and don't yet have the full path, but want to ensure that +you do not walk down paths that can never be a match. + +For example, + +```js +minimatch('/a/b', '/a/*/c/d', { partial: true }) // true, might be /a/b/c/d +minimatch('/a/b', '/**/d', { partial: true }) // true, might be /a/b/.../d +minimatch('/x/y/z', '/a/**/z', { partial: true }) // false, because x !== a +``` + +### allowWindowsEscape + +Windows path separator `\` is by default converted to `/`, which +prohibits the usage of `\` as a escape character. This flag skips that +behavior and allows using the escape character. + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between minimatch and other +implementations, and are intentional. + +If the pattern starts with a `!` character, then it is negated. Set the +`nonegate` flag to suppress this behavior, and treat leading `!` +characters normally. This is perhaps relevant if you wish to start the +pattern with a negative extglob pattern like `!(a|B)`. Multiple `!` +characters at the start of a pattern will negate the pattern multiple +times. + +If a pattern starts with `#`, then it is treated as a comment, and +will not match anything. Use `\#` to match a literal `#` at the +start of a line, or set the `nocomment` flag to suppress this behavior. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.1, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then minimatch.match returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. diff --git a/project starter code/node_modules/minimatch/minimatch.js b/project starter code/node_modules/minimatch/minimatch.js new file mode 100644 index 00000000..fda45ade --- /dev/null +++ b/project starter code/node_modules/minimatch/minimatch.js @@ -0,0 +1,947 @@ +module.exports = minimatch +minimatch.Minimatch = Minimatch + +var path = (function () { try { return require('path') } catch (e) {}}()) || { + sep: '/' +} +minimatch.sep = path.sep + +var GLOBSTAR = minimatch.GLOBSTAR = Minimatch.GLOBSTAR = {} +var expand = require('brace-expansion') + +var plTypes = { + '!': { open: '(?:(?!(?:', close: '))[^/]*?)'}, + '?': { open: '(?:', close: ')?' }, + '+': { open: '(?:', close: ')+' }, + '*': { open: '(?:', close: ')*' }, + '@': { open: '(?:', close: ')' } +} + +// any single thing other than / +// don't need to escape / when using new RegExp() +var qmark = '[^/]' + +// * => any number of characters +var star = qmark + '*?' + +// ** when dots are allowed.

This is a `node-fetch` only API. + +```js +fetch(url).then(res => { + // returns an array of values, instead of a string of comma-separated values + console.log(res.headers.raw()['set-cookie']); +}); +``` + +#### Post data using a file stream + +```js +const { createReadStream } = require('fs'); + +const stream = createReadStream('input.txt'); + +fetch('https://httpbin.org/post', { method: 'POST', body: stream }) + .then(res => res.json()) + .then(json => console.log(json)); +``` + +#### Post with form-data (detect multipart) + +```js +const FormData = require('form-data'); + +const form = new FormData(); +form.append('a', 1); + +fetch('https://httpbin.org/post', { method: 'POST', body: form }) + .then(res => res.json()) + .then(json => console.log(json)); + +// OR, using custom headers +// NOTE: getHeaders() is non-standard API + +const form = new FormData(); +form.append('a', 1); + +const options = { + method: 'POST', + body: form, + headers: form.getHeaders() +} + +fetch('https://httpbin.org/post', options) + .then(res => res.json()) + .then(json => console.log(json)); +``` + +#### Request cancellation with AbortSignal + +> NOTE: You may cancel streamed requests only on Node >= v8.0.0 + +You may cancel requests with `AbortController`. A suggested implementation is [`abort-controller`](https://www.npmjs.com/package/abort-controller). + +An example of timing out a request after 150ms could be achieved as the following: + +```js +import AbortController from 'abort-controller'; + +const controller = new AbortController(); +const timeout = setTimeout( + () => { controller.abort(); }, + 150, +); + +fetch(url, { signal: controller.signal }) + .then(res => res.json()) + .then( + data => { + useData(data) + }, + err => { + if (err.name === 'AbortError') { + // request was aborted + } + }, + ) + .finally(() => { + clearTimeout(timeout); + }); +``` + +See [test cases](https://github.com/bitinn/node-fetch/blob/master/test/test.js) for more examples. + + +## API + +### fetch(url[, options]) + +- `url` A string representing the URL for fetching +- `options` [Options](#fetch-options) for the HTTP(S) request +- Returns: Promise<[Response](#class-response)> + +Perform an HTTP(S) fetch. + +`url` should be an absolute url, such as `https://example.com/`.

+ Nodemon Logo +

+ +# nodemon + +nodemon is a tool that helps develop Node.js based applications by automatically restarting the node application when file changes in the directory are detected. + +nodemon does **not** require *any* additional changes to your code or method of development. nodemon is a replacement wrapper for `node`. To use `nodemon`, replace the word `node` on the command line when executing your script. + +[![NPM version](https://badge.fury.io/js/nodemon.svg)](https://npmjs.org/package/nodemon) +[![Backers on Open Collective](https://opencollective.com/nodemon/backers/badge.svg)](#backers) [![Sponsors on Open Collective](https://opencollective.com/nodemon/sponsors/badge.svg)](#sponsors) + +# Installation + +Either through cloning with git or by using [npm](http://npmjs.org) (the recommended way): + +```bash +npm install -g nodemon # or using yarn: yarn global add nodemon +``` + +And nodemon will be installed globally to your system path. + +You can also install nodemon as a development dependency: + +```bash +npm install --save-dev nodemon # or using yarn: yarn add nodemon -D +``` + +With a local installation, nodemon will not be available in your system path or you can't use it directly from the command line. Instead, the local installation of nodemon can be run by calling it from within an npm script (such as `npm start`) or using `npx nodemon`. + +# Usage + +nodemon wraps your application, so you can pass all the arguments you would normally pass to your app: + +```bash +nodemon [your node app] +``` + +For CLI options, use the `-h` (or `--help`) argument: + +```bash +nodemon -h +``` + +Using nodemon is simple, if my application accepted a host and port as the arguments, I would start it as so: + +```bash +nodemon ./server.js localhost 8080 +``` + +Any output from this script is prefixed with `[nodemon]`, otherwise all output from your application, errors included, will be echoed out as expected. + +You can also pass the `inspect` flag to node through the command line as you would normally: + +```bash +nodemon --inspect ./server.js 80 +``` + +If you have a `package.json` file for your app, you can omit the main script entirely and nodemon will read the `package.json` for the `main` property and use that value as the app ([ref](https://github.com/remy/nodemon/issues/14)). + +nodemon will also search for the `scripts.start` property in `package.json` (as of nodemon 1.1.x). + +Also check out the [FAQ](https://github.com/remy/nodemon/blob/master/faq.md) or [issues](https://github.com/remy/nodemon/issues) for nodemon. + +## Automatic re-running + +nodemon was originally written to restart hanging processes such as web servers, but now supports apps that cleanly exit. If your script exits cleanly, nodemon will continue to monitor the directory (or directories) and restart the script if there are any changes. + +## Manual restarting + +Whilst nodemon is running, if you need to manually restart your application, instead of stopping and restart nodemon, you can type `rs` with a carriage return, and nodemon will restart your process. + +## Config files + +nodemon supports local and global configuration files. These are usually named `nodemon.json` and can be located in the current working directory or in your home directory. An alternative local configuration file can be specified with the `--config ` option. + +The specificity is as follows, so that a command line argument will always override the config file settings: + +- command line arguments +- local config +- global config + +A config file can take any of the command line arguments as JSON key values, for example: + +```json +{ + "verbose": true, + "ignore": ["*.test.js", "**/fixtures/**"], + "execMap": { + "rb": "ruby", + "pde": "processing --sketch={{pwd}} --run" + } +} +``` + +The above `nodemon.json` file might be my global config so that I have support for ruby files and processing files, and I can run `nodemon demo.pde` and nodemon will automatically know how to run the script even though out of the box support for processing scripts. + +A further example of options can be seen in [sample-nodemon.md](https://github.com/remy/nodemon/blob/master/doc/sample-nodemon.md) + +### package.json + +If you want to keep all your package configurations in one place, nodemon supports using `package.json` for configuration. +Specify the config in the same format as you would for a config file but under `nodemonConfig` in the `package.json` file, for example, take the following `package.json`: + +```json +{ + "name": "nodemon", + "homepage": "http://nodemon.io", + "...": "... other standard package.json values", + "nodemonConfig": { + "ignore": ["**/test/**", "**/docs/**"], + "delay": 2500 + } +} +``` + +Note that if you specify a `--config` file or provide a local `nodemon.json` any `package.json` config is ignored. + +*This section needs better documentation, but for now you can also see `nodemon --help config` ([also here](https://github.com/remy/nodemon/blob/master/doc/cli/config.txt))*. + +## Using nodemon as a module + +Please see [doc/requireable.md](doc/requireable.md) + +## Using nodemon as child process + +Please see [doc/events.md](doc/events.md#Using_nodemon_as_child_process) + +## Running non-node scripts + +nodemon can also be used to execute and monitor other programs. nodemon will read the file extension of the script being run and monitor that extension instead of `.js` if there's no `nodemon.json`: + +```bash +nodemon --exec "python -v" ./app.py +``` + +Now nodemon will run `app.py` with python in verbose mode (note that if you're not passing args to the exec program, you don't need the quotes), and look for new or modified files with the `.py` extension. + +### Default executables + +Using the `nodemon.json` config file, you can define your own default executables using the `execMap` property. This is particularly useful if you're working with a language that isn't supported by default by nodemon. + +To add support for nodemon to know about the `.pl` extension (for Perl), the `nodemon.json` file would add: + +```json +{ + "execMap": { + "pl": "perl" + } +} +``` + +Now running the following, nodemon will know to use `perl` as the executable: + +```bash +nodemon script.pl +``` + +It's generally recommended to use the global `nodemon.json` to add your own `execMap` options. However, if there's a common default that's missing, this can be merged in to the project so that nodemon supports it by default, by changing [default.js](https://github.com/remy/nodemon/blob/master/lib/config/defaults.js) and sending a pull request. + +## Monitoring multiple directories + +By default nodemon monitors the current working directory. If you want to take control of that option, use the `--watch` option to add specific paths: + +```bash +nodemon --watch app --watch libs app/server.js +``` + +Now nodemon will only restart if there are changes in the `./app` or `./libs` directory. By default nodemon will traverse sub-directories, so there's no need in explicitly including sub-directories. + +Nodemon also supports unix globbing, e.g `--watch './lib/*'`. The globbing pattern must be quoted. For advanced globbing, [see `picomatch` documentation](https://github.com/micromatch/picomatch#advanced-globbing), the library that nodemon uses through `chokidar` (which in turn uses it through `anymatch`). + +## Specifying extension watch list + +By default, nodemon looks for files with the `.js`, `.mjs`, `.coffee`, `.litcoffee`, and `.json` extensions. If you use the `--exec` option and monitor `app.py` nodemon will monitor files with the extension of `.py`. However, you can specify your own list with the `-e` (or `--ext`) switch like so: + +```bash +nodemon -e js,pug +``` + +Now nodemon will restart on any changes to files in the directory (or subdirectories) with the extensions `.js`, `.pug`. + +## Ignoring files + +By default, nodemon will only restart when a `.js` JavaScript file changes. In some cases you will want to ignore some specific files, directories or file patterns, to prevent nodemon from prematurely restarting your application. + +This can be done via the command line: + +```bash +nodemon --ignore lib/ --ignore tests/ +``` + +Or specific files can be ignored: + +```bash +nodemon --ignore lib/app.js +``` + +Patterns can also be ignored (but be sure to quote the arguments): + +```bash +nodemon --ignore 'lib/*.js' +``` + +**Important** the ignore rules are patterns matched to the full absolute path, and this determines how many files are monitored. If using a wild card glob pattern, it needs to be used as `**` or omitted entirely. For example, `nodemon --ignore '**/test/**'` will work, whereas `--ignore '*/test/*'` will not. + +Note that by default, nodemon will ignore the `.git`, `node_modules`, `bower_components`, `.nyc_output`, `coverage` and `.sass-cache` directories and *add* your ignored patterns to the list. If you want to indeed watch a directory like `node_modules`, you need to [override the underlying default ignore rules](https://github.com/remy/nodemon/blob/master/faq.md#overriding-the-underlying-default-ignore-rules). + +## Application isn't restarting + +In some networked environments (such as a container running nodemon reading across a mounted drive), you will need to use the `legacyWatch: true` which enables Chokidar's polling. + +Via the CLI, use either `--legacy-watch` or `-L` for short: + +```bash +nodemon -L +``` + +Though this should be a last resort as it will poll every file it can find. + +## Delaying restarting + +In some situations, you may want to wait until a number of files have changed. The timeout before checking for new file changes is 1 second. If you're uploading a number of files and it's taking some number of seconds, this could cause your app to restart multiple times unnecessarily. + +To add an extra throttle, or delay restarting, use the `--delay` command: + +```bash +nodemon --delay 10 server.js +``` + +For more precision, milliseconds can be specified. Either as a float: + +```bash +nodemon --delay 2.5 server.js +``` + +Or using the time specifier (ms): + +```bash +nodemon --delay 2500ms server.js +``` + +The delay figure is number of seconds (or milliseconds, if specified) to delay before restarting. So nodemon will only restart your app the given number of seconds after the *last* file change. + +If you are setting this value in `nodemon.json`, the value will always be interpreted in milliseconds. E.g., the following are equivalent: + +```bash +nodemon --delay 2.5 + +{ + "delay": 2500 +} +``` + +## Gracefully reloading down your script + +It is possible to have nodemon send any signal that you specify to your application. + +```bash +nodemon --signal SIGHUP server.js +``` + +Your application can handle the signal as follows. + +```js +process.once("SIGHUP", function () { + reloadSomeConfiguration(); +}) +``` + +Please note that nodemon will send this signal to every process in the process tree. + +If you are using `cluster`, then each workers (as well as the master) will receive the signal. If you wish to terminate all workers on receiving a `SIGHUP`, a common pattern is to catch the `SIGHUP` in the master, and forward `SIGTERM` to all workers, while ensuring that all workers ignore `SIGHUP`. + +```js +if (cluster.isMaster) { + process.on("SIGHUP", function () { + for (const worker of Object.values(cluster.workers)) { + worker.process.kill("SIGTERM"); + } + }); +} else { + process.on("SIGHUP", function() {}) +} +``` + +## Controlling shutdown of your script + +nodemon sends a kill signal to your application when it sees a file update. If you need to clean up on shutdown inside your script you can capture the kill signal and handle it yourself. + +The following example will listen once for the `SIGUSR2` signal (used by nodemon to restart), run the clean up process and then kill itself for nodemon to continue control: + +```js +process.once('SIGUSR2', function () { + gracefulShutdown(function () { + process.kill(process.pid, 'SIGUSR2'); + }); +}); +``` + +Note that the `process.kill` is *only* called once your shutdown jobs are complete. Hat tip to [Benjie Gillam](http://www.benjiegillam.com/2011/08/node-js-clean-restart-and-faster-development-with-nodemon/) for writing this technique up. + +## Triggering events when nodemon state changes + +If you want growl like notifications when nodemon restarts or to trigger an action when an event happens, then you can either `require` nodemon or add event actions to your `nodemon.json` file. + +For example, to trigger a notification on a Mac when nodemon restarts, `nodemon.json` looks like this: + +```json +{ + "events": { + "restart": "osascript -e 'display notification \"app restarted\" with title \"nodemon\"'" + } +} +``` + +A full list of available events is listed on the [event states wiki](https://github.com/remy/nodemon/wiki/Events#states). Note that you can bind to both states and messages. + +## Pipe output to somewhere else + +```js +nodemon({ + script: ..., + stdout: false // important: this tells nodemon not to output to console +}).on('readable', function() { // the `readable` event indicates that data is ready to pick up + this.stdout.pipe(fs.createWriteStream('output.txt')); + this.stderr.pipe(fs.createWriteStream('err.txt')); +}); +``` + +## Using nodemon in your gulp workflow + +Check out the [gulp-nodemon](https://github.com/JacksonGariety/gulp-nodemon) plugin to integrate nodemon with the rest of your project's gulp workflow. + +## Using nodemon in your Grunt workflow + +Check out the [grunt-nodemon](https://github.com/ChrisWren/grunt-nodemon) plugin to integrate nodemon with the rest of your project's grunt workflow. + +## Pronunciation + +> nodemon, is it pronounced: node-mon, no-demon or node-e-mon (like pokémon)? + +Well...I've been asked this many times before. I like that I've been asked this before. There's been bets as to which one it actually is. + +The answer is simple, but possibly frustrating. I'm not saying (how I pronounce it). It's up to you to call it as you like. All answers are correct :) + +## Design principles + +- Fewer flags is better +- Works across all platforms +- Fewer features +- Let individuals build on top of nodemon +- Offer all CLI functionality as an API +- Contributions must have and pass tests + +Nodemon is not perfect, and CLI arguments has sprawled beyond where I'm completely happy, but perhaps it can be reduced a little one day. + +## FAQ + +See the [FAQ](https://github.com/remy/nodemon/blob/master/faq.md) and please add your own questions if you think they would help others. + +## Backers + +Thank you to all [our backers](https://opencollective.com/nodemon#backer)! 🙏 + +[![nodemon backers](https://opencollective.com/nodemon/backers.svg?width=890)](https://opencollective.com/nodemon#backers) + +## Sponsors + +Support this project by becoming a sponsor.

You also _should_ install +the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, +otherwise debug will only use a small handful of basic colors. + + + +#### Web Browser + +Colors are also enabled on "Web Inspectors" that understand the `%c` formatting +option. These are WebKit web inspectors, Firefox ([since version +31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) +and the Firebug plugin for Firefox (any version). + + + + +## Millisecond diff + +When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + + +When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: + + + + +## Conventions + +If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. + +## Wildcards + +The `*` character may be used as a wildcard. Suppose for example your library has +debuggers named "connect:bodyParser", "connect:compress", "connect:session", +instead of listing all three with +`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do +`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + +You can also exclude specific debuggers by prefixing them with a "-" character. +For example, `DEBUG=*,-connect:*` would include all debuggers except those +starting with "connect:". + +## Environment Variables + +When running through Node.js, you can set a few environment variables that will +change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + +__Note:__ The environment variables beginning with `DEBUG_` end up being +converted into an Options object that gets used with `%o`/`%O` formatters. +See the Node.js documentation for +[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) +for the complete list. + +## Formatters + +Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. +Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + + +### Custom formatters + +You can add custom formatters by extending the `debug.formatters` object. +For example, if you wanted to add support for rendering a Buffer as hex with +`%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + + +## Browser Support + +You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), +or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), +if you don't want to build it yourself. + +Debug's enable state is currently persisted by `localStorage`. +Consider the situation shown below where you have `worker:a` and `worker:b`, +and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_. + + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example [_stdout.js_](./examples/node/stdout.js): + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + +## Extend +You can simply extend debugger +```js +const log = require('debug')('auth'); + +//creates new debug instance with extended namespace +const logSign = log.extend('sign'); +const logLogin = log.extend('login'); + +log('hello'); // auth hello +logSign('hello'); //auth:sign hello +logLogin('hello'); //auth:login hello +``` + +## Set dynamically + +You can also enable debug dynamically by calling the `enable()` method : + +```js +let debug = require('debug'); + +console.log(1, debug.enabled('test')); + +debug.enable('test'); +console.log(2, debug.enabled('test')); + +debug.disable(); +console.log(3, debug.enabled('test')); + +``` + +print : +``` +1 false +2 true +3 false +``` + +Usage : +`enable(namespaces)` +`namespaces` can include modes separated by a colon and wildcards. + +Note that calling `enable()` completely overrides previously set DEBUG variable : + +``` +$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' +=> false +``` + +`disable()` + +Will disable all namespaces. The functions returns the namespaces currently +enabled (and skipped). This can be useful if you want to disable debugging +temporarily without knowing what was enabled to begin with. + +For example: + +```js +let debug = require('debug'); +debug.enable('foo:*,-foo:bar'); +let namespaces = debug.disable(); +debug.enable(namespaces); +``` + +Note: There is no guarantee that the string will be identical to the initial +enable string, but semantically they will be identical. + +## Checking whether a debug target is enabled + +After you've created a debug instance, you can determine whether or not it is +enabled by checking the `enabled` property: + +```javascript +const debug = require('debug')('http'); + +if (debug.enabled) { + // do stuff... +} +``` + +You can also manually toggle this property to force the debug instance to be +enabled or disabled. + +## Usage in child processes + +Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process. +For example: + +```javascript +worker = fork(WORKER_WRAP_PATH, [workerPath], { + stdio: [ + /* stdin: */ 0, + /* stdout: */ 'pipe', + /* stderr: */ 'pipe', + 'ipc', + ], + env: Object.assign({}, process.env, { + DEBUG_COLORS: 1 // without this settings, colors won't be shown + }), +}); + +worker.stderr.pipe(process.stderr, { end: false }); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + - Josh Junon + +## Backers + +Support us with a monthly donation and help us continue our activities.

+Blazing fast and accurate glob matcher written in JavaScript.
+No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions. +

+ +
+
+ +## Why picomatch? + +* **Lightweight** - No dependencies +* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function. +* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps) +* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files) +* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes. +* **Well tested** - Thousands of unit tests + +See the [library comparison](#library-comparisons) to other libraries. + +

+ +## Usage + +The main export is a function that takes a glob pattern and an options object and returns a function for matching strings. + +```js +const pm = require('picomatch'); +const isMatch = pm('*.js'); + +console.log(isMatch('abcd')); //=> false +console.log(isMatch('a.js')); //=> true +console.log(isMatch('a.md')); //=> false +console.log(isMatch('a/b.js')); //=> false +``` + +
+ +## API + +### [picomatch](lib/picomatch.js#L32) + +Creates a matcher function from one or more glob patterns. The returned function takes a string to match as its first argument, and returns true if the string is a match. The returned matcher function also takes a boolean as the second argument that, when true, returns an object with additional information. + +**Params** + +* `globs` **{String|Array}**: One or more glob patterns. +* `options` **{Object=}** +* `returns` **{Function=}**: Returns a matcher function. + +**Example** + +```js +const picomatch = require('picomatch'); +// picomatch(glob[, options]); + +const isMatch = picomatch('*.!(*a)'); +console.log(isMatch('a.a')); //=> false +console.log(isMatch('a.b')); //=> true +``` + +### [.test](lib/picomatch.js#L117) + +Test `input` with the given `regex`.

+ +## Options + +### Picomatch options + +The following options may be used with the main `picomatch()` function or any of the methods on the picomatch API. + +| **Option** | **Type** | **Default value** | **Description** | +| --- | --- | --- | --- | +| `basename` | `boolean` | `false` | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes. For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. | +| `bash` | `boolean` | `false` | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). | +| `capture` | `boolean` | `undefined` | Return regex matches in supporting methods. | +| `contains` | `boolean` | `undefined` | Allows glob to match any part of the given string(s). | +| `cwd` | `string` | `process.cwd()` | Current working directory. Used by `picomatch.split()` | +| `debug` | `boolean` | `undefined` | Debug regular expressions when an error is thrown. | +| `dot` | `boolean` | `false` | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true | +| `expandRange` | `function` | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. | +| `failglob` | `boolean` | `false` | Throws an error if no matches are found. Based on the bash option of the same name. | +| `fastpaths` | `boolean` | `true` | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. | +| `flags` | `string` | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. | +| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. | +| `ignore` | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. | +| `keepQuotes` | `boolean` | `false` | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes. | +| `literalBrackets` | `boolean` | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. | +| `matchBase` | `boolean` | `false` | Alias for `basename` | +| `maxLength` | `boolean` | `65536` | Limit the max length of the input string. An error is thrown if the input string is longer than this value. | +| `nobrace` | `boolean` | `false` | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. | +| `nobracket` | `boolean` | `undefined` | Disable matching with regex brackets. | +| `nocase` | `boolean` | `false` | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. | +| `nodupes` | `boolean` | `true` | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. | +| `noext` | `boolean` | `false` | Alias for `noextglob` | +| `noextglob` | `boolean` | `false` | Disable support for matching with extglobs (like `+(a\|b)`) | +| `noglobstar` | `boolean` | `false` | Disable support for matching nested directories with globstars (`**`) | +| `nonegate` | `boolean` | `false` | Disable support for negating with leading `!` | +| `noquantifiers` | `boolean` | `false` | Disable support for regex quantifiers (like `a{1,2}`) and treat them as brace patterns to be expanded. | +| [onIgnore](#optionsonIgnore) | `function` | `undefined` | Function to be called on ignored items. | +| [onMatch](#optionsonMatch) | `function` | `undefined` | Function to be called on matched items. | +| [onResult](#optionsonResult) | `function` | `undefined` | Function to be called on all items, regardless of whether or not they are matched or ignored. | +| `posix` | `boolean` | `false` | Support POSIX character classes ("posix brackets"). | +| `posixSlashes` | `boolean` | `undefined` | Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself | +| `prepend` | `boolean` | `undefined` | String to prepend to the generated regex used for matching. | +| `regex` | `boolean` | `false` | Use regular expression rules for `+` (instead of matching literal `+`), and for stars that follow closing parentheses or brackets (as in `)*` and `]*`). | +| `strictBrackets` | `boolean` | `undefined` | Throw an error if brackets, braces, or parens are imbalanced. | +| `strictSlashes` | `boolean` | `undefined` | When true, picomatch won't match trailing slashes with single stars. | +| `unescape` | `boolean` | `undefined` | Remove backslashes preceding escaped characters in the glob pattern. By default, backslashes are retained. | +| `unixify` | `boolean` | `undefined` | Alias for `posixSlashes`, for backwards compatibility. | + +picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error. + +### Scan Options + +In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method. + +| **Option** | **Type** | **Default value** | **Description** | +| --- | --- | --- | --- | +| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern | +| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true | + +**Example** + +```js +const picomatch = require('picomatch'); +const result = picomatch.scan('!./foo/*.js', { tokens: true }); +console.log(result); +// { +// prefix: '!./', +// input: '!./foo/*.js', +// start: 3, +// base: 'foo', +// glob: '*.js', +// isBrace: false, +// isBracket: false, +// isGlob: true, +// isExtglob: false, +// isGlobstar: false, +// negated: true, +// maxDepth: 2, +// tokens: [ +// { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true }, +// { value: 'foo', depth: 1, isGlob: false }, +// { value: '*.js', depth: 1, isGlob: true } +// ], +// slashes: [ 2, 6 ], +// parts: [ 'foo', '*.js' ] +// } +``` + +
+ +### Options Examples + +#### options.expandRange + +**Type**: `function` + +**Default**: `undefined` + +Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need. + +**Example** + +The following example shows how to create a glob that matches a folder + +```js +const fill = require('fill-range'); +const regex = pm.makeRe('foo/{01..25}/bar', { + expandRange(a, b) { + return `(${fill(a, b, { toRegex: true })})`; + } +}); + +console.log(regex); +//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/ + +console.log(regex.test('foo/00/bar')) // false +console.log(regex.test('foo/01/bar')) // true +console.log(regex.test('foo/10/bar')) // true +console.log(regex.test('foo/22/bar')) // true +console.log(regex.test('foo/25/bar')) // true +console.log(regex.test('foo/26/bar')) // false +``` + +#### options.format + +**Type**: `function` + +**Default**: `undefined` + +Custom function for formatting strings before they're matched. + +**Example** + +```js +// strip leading './' from strings +const format = str => str.replace(/^\.\//, ''); +const isMatch = picomatch('foo/*.js', { format }); +console.log(isMatch('./foo/bar.js')); //=> true +``` + +#### options.onMatch + +```js +const onMatch = ({ glob, regex, input, output }) => { + console.log({ glob, regex, input, output }); +}; + +const isMatch = picomatch('*', { onMatch }); +isMatch('foo'); +isMatch('bar'); +isMatch('baz'); +``` + +#### options.onIgnore + +```js +const onIgnore = ({ glob, regex, input, output }) => { + console.log({ glob, regex, input, output }); +}; + +const isMatch = picomatch('*', { onIgnore, ignore: 'f*' }); +isMatch('foo'); +isMatch('bar'); +isMatch('baz'); +``` + +#### options.onResult + +```js +const onResult = ({ glob, regex, input, output }) => { + console.log({ glob, regex, input, output }); +}; + +const isMatch = picomatch('*', { onResult, ignore: 'f*' }); +isMatch('foo'); +isMatch('bar'); +isMatch('baz'); +``` + +
+
+ +## Globbing features + +* [Basic globbing](#basic-globbing) (Wildcard matching) +* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching) + +### Basic globbing + +| **Character** | **Description** | +| --- | --- | +| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. | +| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. | +| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots. | +| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. | + +#### Matching behavior vs. Bash + +Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions: + +* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`. +* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`. + +
+ +### Advanced globbing + +* [extglobs](#extglobs) +* [POSIX brackets](#posix-brackets) +* [Braces](#brace-expansion) + +#### Extglobs + +| **Pattern** | **Description** | +| --- | --- | +| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` | +| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` | +| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` | +| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` | +| `!(pattern)` | Match _anything but_ `pattern` | + +**Examples** + +```js +const pm = require('picomatch'); + +// *(pattern) matches ZERO or more of "pattern" +console.log(pm.isMatch('a', 'a*(z)')); // true +console.log(pm.isMatch('az', 'a*(z)')); // true +console.log(pm.isMatch('azzz', 'a*(z)')); // true + +// +(pattern) matches ONE or more of "pattern" +console.log(pm.isMatch('a', 'a*(z)')); // true +console.log(pm.isMatch('az', 'a*(z)')); // true +console.log(pm.isMatch('azzz', 'a*(z)')); // true + +// supports multiple extglobs +console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false + +// supports nested extglobs +console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true +``` + +#### POSIX brackets + +POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true. + +**Enable POSIX bracket support** + +```js +console.log(pm.makeRe('[[:word:]]+', { posix: true })); +//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/ +``` + +**Supported POSIX classes** + +The following named POSIX bracket expressions are supported: + +* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]` +* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`. +* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`. +* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`. +* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`. +* `[:digit:]` - Numerical digits, equivalent to `[0-9]`. +* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`. +* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`. +* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`. +* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`. +* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`. +* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`. +* `[:word:]` - Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`. +* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`. + +See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information. + +### Braces + +Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces. + +### Matching special characters as literals + +If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes: + +**Special Characters** + +Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms. + +To match any of the following characters as literals: `$^*+?()[] + +Examples: + +```js +console.log(pm.makeRe('foo/bar \\(1\\)')); +console.log(pm.makeRe('foo/bar \\(1\\)')); +``` + +

+ +## Philosophies + +The goal of this library is to be blazing fast, without compromising on accuracy. + +**Accuracy** + +The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`. + +Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements. + +**Performance** + +Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer. + +

Default currently 6, but in the future may calculate best mode. +- `inputColorType` - the input colorType - see constants.

Note that it is not 100% reliable with transparent colours because that requires knowing the background colour the bitmap is rendered on to. + +In tests against PNG suite it compared 100% with chrome on all 8 bit and below images. On IE there were some differences. + +The following example reads a file, adjusts the gamma (which sets the gamma to 0) and writes it out again, effectively removing any gamma correction from the image. + +```js +fs.createReadStream('in.png') + .pipe(new PNG()) + .on('parsed', function() { + this.adjustGamma(); + this.pack().pipe(fs.createWriteStream('out.png')); + }); +``` + +### Property: width +Width of image in pixels + + +### Property: height +Height of image in pixels + + +### Property: data +Buffer of image pixel data. Every pixel consists 4 bytes: R, G, B, A (opacity). + + +### Property: gamma +Gamma of image (0 if not specified) + +## Packing a PNG and removing alpha (RGBA to RGB) + +When removing the alpha channel from an image, there needs to be a background color to correctly +convert each pixel's transparency to the appropriate RGB value. By default, pngjs will flatten +the image against a white background. You can override this in the options: + +```js +var fs = require('fs'), + PNG = require('pngjs').PNG; + +fs.createReadStream('in.png') + .pipe(new PNG({ + colorType: 2, + bgColor: { + red: 0, + green: 255, + blue: 0 + } + })) + .on('parsed', function() { + this.pack().pipe(fs.createWriteStream('out.png')); + }); +``` + +# Sync API + +## PNG.sync + +### PNG.sync.read(buffer) + +Take a buffer and returns a PNG image.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +'use strict'; + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); + +/**/ +var util = require('core-util-is'); +util.inherits = require('inherits'); +/**/ + +util.inherits(Transform, Duplex); + +function TransformState(stream) { + this.afterTransform = function (er, data) { + return afterTransform(stream, er, data); + }; + + this.needTransform = false; + this.transforming = false; + this.writecb = null; + this.writechunk = null; + this.writeencoding = null; +} + +function afterTransform(stream, er, data) { + var ts = stream._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); + + ts.writechunk = null; + ts.writecb = null; + + if (data !== null && data !== undefined) stream.push(data); + + cb(er); + + var rs = stream._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + stream._read(rs.highWaterMark); + } +} + +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + + Duplex.call(this, options); + + this._transformState = new TransformState(this); + + var stream = this; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + + if (typeof options.flush === 'function') this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.once('prefinish', function () { + if (typeof this._flush === 'function') this._flush(function (er, data) { + done(stream, er, data); + });else done(stream); + }); +} + +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

A variable that is +not set has the same meaning as a variable that is set but has no value. + +### NO\_PROXY + +`NO_PROXY` is a list of host names (optionally with a port). If the input URL +matches any of the entries in `NO_PROXY`, then the input URL should be fetched +by a direct request (i.e. without a proxy). + +Matching follows the following rules: + +- `NO_PROXY=*` disables all proxies. +- Space and commas may be used to separate the entries in the `NO_PROXY` list. +- If `NO_PROXY` does not contain any entries, then proxies are never disabled. +- If a port is added after the host name, then the ports must match. If the URL + does not have an explicit port name, the protocol's default port is used. +- Generally, the proxy is only disabled if the host name is an exact match for + an entry in the `NO_PROXY` list. The only exceptions are entries that start + with a dot or with a wildcard; then the proxy is disabled if the host name + ends with the entry. + +See `test.js` for examples of what should match and what does not. + +### \*\_PROXY + +The environment variable used for the proxy depends on the protocol of the URL. +For example, `https://example.com` uses the "https" protocol, and therefore the +proxy to be used is `HTTPS_PROXY` (_NOT_ `HTTP_PROXY`, which is _only_ used for +http:-URLs). + +The library is not limited to http(s), other schemes such as +`FTP_PROXY` (ftp:), +`WSS_PROXY` (wss:), +`WS_PROXY` (ws:) +are also supported. + +If present, `ALL_PROXY` is used as fallback if there is no other match. + + +## External resources +The exact way of parsing the environment variables is not codified in any +standard.

Streams Working Group + +The Node.js Streams is jointly governed by a Working Group +(WG) +that is responsible for high-level guidance of the project. + +The WG has final authority over this project including: + +* Technical direction +* Project governance and process (including this policy) +* Contribution policy +* GitHub repository hosting +* Conduct guidelines +* Maintaining the list of additional Collaborators + +For the current list of WG members, see the project +[README.md](./README.md#current-project-team-members). + +### Collaborators + +The readable-stream GitHub repository is +maintained by the WG and additional Collaborators who are added by the +WG on an ongoing basis. + +Individuals making significant and valuable contributions are made +Collaborators and given commit-access to the project. These +individuals are identified by the WG and their addition as +Collaborators is discussed during the WG meeting. + +_Note:_ If you make a significant contribution and are not considered +for commit-access log an issue or contact a WG member directly and it +will be brought up in the next WG meeting. + +Modifications of the contents of the readable-stream repository are +made on +a collaborative basis. Anybody with a GitHub account may propose a +modification via pull request and it will be considered by the project +Collaborators. All pull requests must be reviewed and accepted by a +Collaborator with sufficient expertise who is able to take full +responsibility for the change. In the case of pull requests proposed +by an existing Collaborator, an additional Collaborator is required +for sign-off. Consensus should be sought if additional Collaborators +participate and there is disagreement around a particular +modification. See _Consensus Seeking Process_ below for further detail +on the consensus model used for governance. + +Collaborators may opt to elevate significant or controversial +modifications, or modifications that have not found consensus to the +WG for discussion by assigning the ***WG-agenda*** tag to a pull +request or issue. The WG should serve as the final arbiter where +required. + +For the current list of Collaborators, see the project +[README.md](./README.md#members). + +### WG Membership + +WG seats are not time-limited. There is no fixed size of the WG. +However, the expected target is between 6 and 12, to ensure adequate +coverage of important areas of expertise, balanced with the ability to +make decisions efficiently. + +There is no specific set of requirements or qualifications for WG +membership beyond these rules. + +The WG may add additional members to the WG by unanimous consensus. + +A WG member may be removed from the WG by voluntary resignation, or by +unanimous consensus of all other WG members. + +Changes to WG membership should be posted in the agenda, and may be +suggested as any other agenda item (see "WG Meetings" below). + +If an addition or removal is proposed during a meeting, and the full +WG is not in attendance to participate, then the addition or removal +is added to the agenda for the subsequent meeting. This is to ensure +that all members are given the opportunity to participate in all +membership decisions. If a WG member is unable to attend a meeting +where a planned membership decision is being made, then their consent +is assumed. + +No more than 1/3 of the WG members may be affiliated with the same +employer. If removal or resignation of a WG member, or a change of +employment by a WG member, creates a situation where more than 1/3 of +the WG membership shares an employer, then the situation must be +immediately remedied by the resignation or removal of one or more WG +members affiliated with the over-represented employer(s). + +### WG Meetings + +The WG meets occasionally on a Google Hangout On Air. A designated moderator +approved by the WG runs the meeting. Each meeting should be +published to YouTube. + +Items are added to the WG agenda that are considered contentious or +are modifications of governance, contribution policy, WG membership, +or release process. + +The intention of the agenda is not to approve or review all patches; +that should happen continuously on GitHub and be handled by the larger +group of Collaborators. + +Any community member or contributor can ask that something be added to +the next meeting's agenda by logging a GitHub Issue. Any Collaborator, +WG member or the moderator can add the item to the agenda by adding +the ***WG-agenda*** tag to the issue. + +Prior to each WG meeting the moderator will share the Agenda with +members of the WG. WG members can add any items they like to the +agenda at the beginning of each meeting. The moderator and the WG +cannot veto or remove items. + +The WG may invite persons or representatives from certain projects to +participate in a non-voting capacity. + +The moderator is responsible for summarizing the discussion of each +agenda item and sends it as a pull request after the meeting. + +### Consensus Seeking Process + +The WG follows a +[Consensus +Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) +decision-making model. + +When an agenda item has appeared to reach a consensus the moderator +will ask "Does anyone object?" as a final call for dissent from the +consensus. + +If an agenda item cannot reach a consensus a WG member can call for +either a closing vote or a vote to table the issue to the next +meeting. The call for a vote must be seconded by a majority of the WG +or else the discussion will continue. Simple majority wins. + +Note that changes to WG membership require a majority consensus.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +'use strict'; + +module.exports = Transform; +var _require$codes = require('../errors').codes, + ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED, + ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK, + ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING, + ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0; +var Duplex = require('./_stream_duplex'); +require('inherits')(Transform, Duplex); +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + var cb = ts.writecb; + if (cb === null) { + return this.emit('error', new ERR_MULTIPLE_CALLBACK()); + } + ts.writechunk = null; + ts.writecb = null; + if (data != null) + // single equals check for both `null` and `undefined` + this.push(data); + cb(er); + var rs = this._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + Duplex.call(this, options); + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + if (typeof options.flush === 'function') this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.on('prefinish', prefinish); +} +function prefinish() { + var _this = this; + if (typeof this._flush === 'function' && !this._readableState.destroyed) { + this._flush(function (er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } +} +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

Example: inaccessible to the user. +- `on('error', (error) => {})` fatal `Error` which also ends the stream. Example: illegal options where passed. +- `on('end')` — we are done. Called when all entries were found and no more will be emitted. +- `on('close')` — stream is destroyed via `stream.destroy()`. + Could be useful if you want to manually abort even on a non fatal error. + At that point the stream is no longer `readable` and no more entries, warning or errors are emitted +- To learn more about streams, consult the very detailed [nodejs streams documentation](https://nodejs.org/api/stream.html) + or the [stream-handbook](https://github.com/substack/stream-handbook) + +`const entries = await readdirp.promise(root[, options])` — **Promise API**.

A `Function`, Glob string or Array of glob strings. + - **Function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry + - **Glob string**: a string (e.g., `*.js`) which is matched using [picomatch](https://github.com/micromatch/picomatch), so go there for more + information. Globstars (`**`) are not supported since specifying a recursive pattern for an already recursive function doesn't make sense. Negated globs (as explained in the minimatch documentation) are allowed, e.g., `!*.txt` matches everything but text files. + - **Array of glob strings**: either need to be all inclusive or all exclusive (negated) patterns otherwise an error is thrown. + `['*.json', '*.js']` includes all JavaScript and Json files. + `['!.git', '!node_modules']` includes all directories except the '.git' and 'node_modules'. + - Directories that do not pass a filter will not be recursed into. +- `directoryFilter: ['!.git']`: filter to include/exclude directories found and to recurse into. Directories that do not pass a filter will not be recursed into. +- `depth: 5`: depth at which to stop recursing even if more subdirectories are found +- `type: 'files'`: determines if data events on the stream should be emitted for `'files'` (default), `'directories'`, `'files_directories'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes. +- `alwaysStat: false`: always return `stats` property for every file. Default is `false`, readdirp will return `Dirent` entries. Setting it to `true` can double readdir execution time - use it only when you need file `size`, `mtime` etc. Cannot be enabled on node <10.10.0. +- `lstat: false`: include symlink entries in the stream along with files.

Fixes race conditions related to `for-await` looping. +- 3.2 (Oct 14, 2019) improves performance by 250% and makes streams implementation more idiomatic. +- 3.1 (Jul 7, 2019) brings `bigint` support to `stat` output on Windows. This is backwards-incompatible for some cases. Be careful. It you use it incorrectly, you'll see "TypeError: Cannot mix BigInt and other types, use explicit conversions". +- 3.0 brings huge performance improvements and stream backpressure support. +- Upgrading 2.x to 3.x: + - Signature changed from `readdirp(options)` to `readdirp(root, options)` + - Replaced callback API with promise API. + - Renamed `entryType` option to `type` + - Renamed `entryType: 'both'` to `'files_directories'` + - `EntryInfo` + - Renamed `stat` to `stats` + - Emitted only when `alwaysStat: true` + - `dirent` is emitted instead of `stats` by default with `alwaysStat: false` + - Renamed `name` to `basename` + - Removed `parentDir` and `fullParentDir` properties +- Supported node.js versions: + - 3.x: node 8+ + - 2.x: node 0.6+ + +## License + +Copyright (c) 2012-2019 Thorsten Lorenz, Paul Miller () + +MIT License, see [LICENSE](LICENSE) file. diff --git a/project starter code/node_modules/readdirp/index.d.ts b/project starter code/node_modules/readdirp/index.d.ts new file mode 100644 index 00000000..cbbd76ca --- /dev/null +++ b/project starter code/node_modules/readdirp/index.d.ts @@ -0,0 +1,43 @@ +// TypeScript Version: 3.2 + +/// + +import * as fs from 'fs';

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

For backwards compatibility reasons, if the `options` + argument is a boolean value instead of an object, it is interpreted + to be the `loose` param. +- `includePrerelease`: Set to suppress the [default + behavior](https://github.com/npm/node-semver#prerelease-tags) of + excluding prerelease tagged versions from ranges unless they are + explicitly opted into. + +Strict-mode Comparators and Ranges will be strict about the SemVer +strings that they parse. + +* `valid(v)`: Return the parsed version, or null if it's not valid. +* `inc(v, release, options, identifier, identifierBase)`: + Return the version incremented by the release + type (`major`, `premajor`, `minor`, `preminor`, `patch`, + `prepatch`, or `prerelease`), or null if it's not valid + * `premajor` in one call will bump the version up to the next major + version and down to a prerelease of that major version. + `preminor`, and `prepatch` work the same way. + * If called from a non-prerelease version, `prerelease` will work the + same as `prepatch`. It increments the patch version and then makes a + prerelease. If the input version is already a prerelease it simply + increments it. + * `identifier` can be used to prefix `premajor`, `preminor`, + `prepatch`, or `prerelease` version increments. `identifierBase` + is the base to be used for the `prerelease` identifier. +* `prerelease(v)`: Returns an array of prerelease components, or null + if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]` +* `major(v)`: Return the major version number. +* `minor(v)`: Return the minor version number. +* `patch(v)`: Return the patch version number. +* `intersects(r1, r2, loose)`: Return true if the two supplied ranges + or comparators intersect. +* `parse(v)`: Attempt to parse a string as a semantic version, returning either + a `SemVer` object or `null`. + +### Comparison + +* `gt(v1, v2)`: `v1 > v2` +* `gte(v1, v2)`: `v1 >= v2` +* `lt(v1, v2)`: `v1 < v2` +* `lte(v1, v2)`: `v1 <= v2` +* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent, + even if they're not the same string. You already know how to + compare strings. +* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`. +* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call + the corresponding function above. `"==="` and `"!=="` do simple + string comparison, but are included for completeness. Throws if an + invalid comparison string is provided. +* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if + `v2` is greater. Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for ``compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on + the `compareBuild` function in descending order. + +### Comparators + +* `intersects(comparator)`: Return true if the comparators intersect + +### Ranges + +* `validRange(range)`: Return the valid range or null if it's not valid +* `satisfies(version, range)`: Return true if the version satisfies the + range. +* `maxSatisfying(versions, range)`: Return the highest version in the list + that satisfies the range, or `null` if none of them do. +* `minSatisfying(versions, range)`: Return the lowest version in the list + that satisfies the range, or `null` if none of them do. +* `minVersion(range)`: Return the lowest version that can match + the given range. +* `gtr(version, range)`: Return `true` if the version is greater than all the + versions possible in the range. +* `ltr(version, range)`: Return `true` if the version is less than all the + versions possible in the range. +* `outside(version, range, hilo)`: Return true if the version is outside + the bounds of the range in either the high or low direction. The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

-Keep most of the number bounding out of this function - don't worry about [0,1] or [0,100] or [0,360]
-Just return an object and let the conversion functions handle that.
-This way the result will be the same whether the tinycolor is initialized with string or object.

TinyColor

-		
Fast, small color manipulation and conversion for JavaScript

-
-		

-			TinyColor is a micro framework for inputting colors and
-			outputting colors as different formats.
-			Input is meant to be as permissive as possible.
-		

-
-		
Usage Documentation

-		
Read all the documentation on the TinyColor project page on
-			github.

-
-		
Code

-		
View the annotated source code or see the full source on github.

-
-		
Tests

-				

-					Or try these:
-					red
-					0f0
-					rgb 255 128 128
-					hsl(0, 100%, 50%)
-					hsv 0, 100%, 50%
-				

-				
And I'll tell you what I know about it:

+
+> Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save to-regex-range
+```
+
+
      
+What does this do?
+
+
      
+
+This libary generates the `source` string to be passed to `new RegExp()` for matching a range of numbers.
+
+**Example**
+
+```js
+const toRegexRange = require('to-regex-range');
+const regex = new RegExp(toRegexRange('15', '95'));
+```
+
+A string is returned so that you can do whatever you need with it before passing it to `new RegExp()` (like adding `^` or `$` boundaries, defining flags, or combining it another string).
+
+
      
+
+
      
+
+
      
+Why use this library?
+
+
      
+
+### Convenience
+
+Creating regular expressions for matching numbers gets deceptively complicated pretty fast.
+
+For example, let's say you need a validation regex for matching part of a user-id, postal code, social security number, tax id, etc:
+
+* regex for matching `1` => `/1/` (easy enough)
+* regex for matching `1` through `5` => `/[1-5]/` (not bad...)
+* regex for matching `1` or `5` => `/(1|5)/` (still easy...)
+* regex for matching `1` through `50` => `/([1-9]|[1-4][0-9]|50)/` (uh-oh...)
+* regex for matching `1` through `55` => `/([1-9]|[1-4][0-9]|5[0-5])/` (no prob, I can do this...)
+* regex for matching `1` through `555` => `/([1-9]|[1-9][0-9]|[1-4][0-9]{2}|5[0-4][0-9]|55[0-5])/` (maybe not...)
+* regex for matching `0001` through `5555` => `/(0{3}[1-9]|0{2}[1-9][0-9]|0[1-9][0-9]{2}|[1-4][0-9]{3}|5[0-4][0-9]{2}|55[0-4][0-9]|555[0-5])/` (okay, I get the point!)
+
+The numbers are contrived, but they're also really basic. In the real world you might need to generate a regex on-the-fly for validation.
+
+**Learn more**
+
+If you're interested in learning more about [character classes](http://www.regular-expressions.info/charclass.html) and other regex features, I personally have always found [regular-expressions.info](http://www.regular-expressions.info/charclass.html) to be pretty useful.
+
+### Heavily tested
+
+As of April 07, 2019, this library runs [>1m test assertions](./test/test.js) against generated regex-ranges to provide brute-force verification that results are correct.
+
+Tests run in ~280ms on my MacBook Pro, 2.5 GHz Intel Core i7.
+
+### Optimized
+
+Generated regular expressions are optimized:
+
+* duplicate sequences and character classes are reduced using quantifiers
+* smart enough to use `?` conditionals when number(s) or range(s) can be positive or negative
+* uses fragment caching to avoid processing the same exact string more than once
+
+
      
+
+
      
+
+## Usage
+
+Add this library to your javascript application with the following line of code
+
+```js
+const toRegexRange = require('to-regex-range');
+```
+
+The main export is a function that takes two integers: the `min` value and `max` value (formatted as strings or numbers).
+
+```js
+const source = toRegexRange('15', '95');
+//=> 1[5-9]|[2-8][0-9]|9[0-5]
+
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('14')); //=> false
+console.log(regex.test('50')); //=> true
+console.log(regex.test('94')); //=> true
+console.log(regex.test('96')); //=> false
+```
+
+## Options
+
+### options.capture
+
+**Type**: `boolean`
+
+**Deafault**: `undefined`
+
+Wrap the returned value in parentheses when there is more than one regex condition. Useful when you're dynamically generating ranges.
+
+```js
+console.log(toRegexRange('-10', '10'));
+//=> -[1-9]|-?10|[0-9]
+
+console.log(toRegexRange('-10', '10', { capture: true }));
+//=> (-[1-9]|-?10|[0-9])
+```
+
+### options.shorthand
+
+**Type**: `boolean`
+
+**Deafault**: `undefined`
+
+Use the regex shorthand for `[0-9]`:
+
+```js
+console.log(toRegexRange('0', '999999'));
+//=> [0-9]|[1-9][0-9]{1,5}
+
+console.log(toRegexRange('0', '999999', { shorthand: true }));
+//=> \d|[1-9]\d{1,5}
+```
+
+### options.relaxZeros
+
+**Type**: `boolean`
+
+**Default**: `true`
+
+This option relaxes matching for leading zeros when when ranges are zero-padded.
+
+```js
+const source = toRegexRange('-0010', '0010');
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('-10')); //=> true
+console.log(regex.test('-010')); //=> true
+console.log(regex.test('-0010')); //=> true
+console.log(regex.test('10')); //=> true
+console.log(regex.test('010')); //=> true
+console.log(regex.test('0010')); //=> true
+```
+
+When `relaxZeros` is false, matching is strict:
+
+```js
+const source = toRegexRange('-0010', '0010', { relaxZeros: false });
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('-10')); //=> false
+console.log(regex.test('-010')); //=> false
+console.log(regex.test('-0010')); //=> true
+console.log(regex.test('10')); //=> false
+console.log(regex.test('010')); //=> false
+console.log(regex.test('0010')); //=> true
+```

+
+## Heads up!
+
+**Order of arguments**
+
+When the `min` is larger than the `max`, values will be flipped to create a valid range:
+
+```js
+toRegexRange('51', '29');
+```
+
+Is effectively flipped to:
+
+```js
+toRegexRange('29', '51');
+//=> 29|[3-4][0-9]|5[0-1]
+```
+
+**Steps / increments**
+
+This library does not support steps (increments). A pr to add support would be welcome.
+
+## History
+
+### v2.0.0 - 2017-04-21
+
+**New features**
+
+Adds support for zero-padding!
+
+### v1.0.0
+
+**Optimizations**
+
+Repeating ranges are now grouped using quantifiers. rocessing time is roughly the same, but the generated regex is much smaller, which should result in faster matching.

+# token-types
+
+A primitive token library used to read and write from a node `Buffer`.
+Although it is possible to use this module directly, it is primary designed to be used with [strtok3 tokenizer](https://github.com/Borewit/strtok3).
+
+## Installation
+
+```sh
+npm install --save token-types
+```
+Usually in combination with [strtok3](https://github.com/Borewit/strtok3):
+```sh
+npm install --save strtok3
+```
+
+Using TypeScript you should also install [@tokenizer/token](https://github.com/Borewit/tokenizer-token) as a development
+dependency:
+
+```shell
+npm install --save-dev @tokenizer/token
+```
+
+
+## Example
+
+```js
+const strtok3 = require('strtok3');
+const token = require('token-types');
+    
+(async () => {
+
+  const tokenizer = await strtok3.fromFile("somefile.bin");
+  try {
+    const myNumber = await tokenizer.readToken(token.Float32_BE);
+    console.log(`My number: ${myNumber}`);
+  } finally {
+    tokenizer.close(); // Close the file
+  } 
+})();
+```
+
+## Tokens
+
+### Numeric tokens
+
+`node-strtok` supports a wide variety of numerical tokens out of the box:
+
+| Token         | Number           | Bits | Endianness     |
+|---------------|------------------|------|----------------|
+| `UINT8`       | Unsigned integer |    8 | n/a            |
+| `UINT16_BE`   | Unsigned integer |   16 | big endian     |
+| `UINT16_LE`   | Unsigned integer |   16 | little endian  |
+| `UINT24_BE`   | Unsigned integer |   24 | big endian     |
+| `UINT24_LE`   | Unsigned integer |   24 | little endian  |
+| `UINT32_BE`   | Unsigned integer |   32 | big endian     |
+| `UINT32_LE`   | Unsigned integer |   32 | little endian  |
+| `UINT64_BE`   | Unsigned integer |   64 | big endian     |
+| `UINT64_LE`*  | Unsigned integer |   64 | little endian  |
+| `INT8`        | Signed integer   |    8 | n/a            |
+| `INT16_BE`    | Signed integer   |   16 | big endian     |
+| `INT16_LE`    | Signed integer   |   16 | little endian  |
+| `INT24_BE`    | Signed integer   |   24 | big endian     |
+| `INT24_LE`    | Signed integer   |   24 | little endian  |
+| `INT32_BE`    | Signed integer   |   32 | big endian     |
+| `INT32_LE`    | Signed integer   |   32 | little endian  |
+| `INT64_BE`    | Signed integer   |   64 | big endian     |
+| `INT64_LE`*   | Signed integer   |   64 | little endian  |
+| `Float16_BE`  | IEEE 754 float   |   16 | big endian     |
+| `Float16_LE`  | IEEE 754 float   |   16 | little endian  |
+| `Float32_BE`  | IEEE 754 float   |   32 | big endian     |
+| `Float32_LE`  | IEEE 754 float   |   32 | little endian  |
+| `Float64_BE`  | IEEE 754 float   |   64 | big endian     |
+| `Float64_LE`  | IEEE 754 float   |   64 | little endian  |
+| `Float80_BE`* | IEEE 754 float   |   80 | big endian     |
+| `Float80_LE`* | IEEE 754 float   |   80 | little endian  |
+
+### Other tokens
+
+String types:
+*   Windows-1252
+*   ISO-8859-1
+  
+*) The tokens exceed the JavaScript IEEE 754 64-bit Floating Point precision, decoding and encoding is best effort based.
+
+### Custom token
+
+Complex tokens can be added, which makes very suitable for reading binary files or network messages:
+```js
+ ExtendedHeader = {
+    len: 10,
+
+    get: (buf, off) => {
+      return {
+        // Extended header size
+        size: Token.UINT32_BE.get(buf, off),
+        // Extended Flags
+        extendedFlags: Token.UINT16_BE.get(buf, off + 4),
+        // Size of padding
+        sizeOfPadding: Token.UINT32_BE.get(buf, off + 6),
+        // CRC data present
+        crcDataPresent: common.strtokBITSET.get(buf, off + 4, 31)
+      };
+    }
+  };
+```

+# node-touch
+
+For all your node touching needs.
+
+## Installing
+
+```bash
+npm install touch
+```
+
+## CLI Usage:
+
+See `man touch`
+
+This package exports a binary called `nodetouch` that works mostly
+like the unix builtin `touch(1)`.
+
+## API Usage:
+
+```javascript
+var touch = require("touch")
+```
+
+Gives you the following functions:
+
+* `touch(filename, options, cb)`
+* `touch.sync(filename, options)`
+* `touch.ftouch(fd, options, cb)`
+* `touch.ftouchSync(fd, options)`
+
+All the `options` objects are optional.
+
+All the async functions return a Promise.  If a callback function is
+provided, then it's attached to the Promise.
+
+## Options
+
+* `force` like `touch -f` Boolean
+* `time` like `touch -t ` Can be a Date object, or any parseable
+  Date string, or epoch ms number.
+* `atime` like `touch -a` Can be either a Boolean, or a Date.
+* `mtime` like `touch -m` Can be either a Boolean, or a Date.
+* `ref` like `touch -r ` Must be path to a file.
+* `nocreate` like `touch -c` Boolean
+
+If neither `atime` nor `mtime` are set, then both values are set.  If
+one of them is set, then the other is not.
+
+## cli
+

+# undefsafe
+
+Simple *function* for retrieving deep object properties without getting "Cannot read property 'X' of undefined"
+
+Can also be used to safely set deep values.
+
+## Usage
+
+```js
+var object = {
+  a: {
+    b: {
+      c: 1,
+      d: [1,2,3],
+      e: 'remy'
+    }
+  }
+};
+
+console.log(undefsafe(object, 'a.b.e')); // "remy"
+console.log(undefsafe(object, 'a.b.not.found')); // undefined
+```
+
+Demo: [https://jsbin.com/eroqame/3/edit?js,console](https://jsbin.com/eroqame/3/edit?js,console)
+
+## Setting
+
+```js
+var object = {
+  a: {
+    b: [1,2,3]
+  }
+};
+
+// modified object
+var res = undefsafe(object, 'a.b.0', 10);
+
+console.log(object); // { a: { b: [10, 2, 3] } }
+console.log(res); // 1 - previous value
+```
+
+## Star rules in paths
+
+As of 1.2.0, `undefsafe` supports a `*` in the path if you want to search all of the properties (or array elements) for a particular element.
+
+The function will only return a single result, either the 3rd argument validation value, or the first positive match. For example, the following github data:
+
+```js
+const githubData = {
+        commits: [{
+          modified: [
+            "one",
+            "two"
+          ]
+        }, /* ... */ ]
+      };
+
+// first modified file found in the first commit
+console.log(undefsafe(githubData, 'commits.*.modified.0'));
+
+// returns `two` or undefined if not found
+console.log(undefsafe(githubData, 'commits.*.modified.*', 'two'));
+```

-# UTIF.js
-A small, fast and advanced TIFF / EXIF (+ DNG and other TIFF-ish files) decoder and encoder. It is the main TIFF library for [Photopea image editor](https://www.photopea.com). Try to open your TIFF file with Photopea to see, if UTIF.js can parse it.
-
-* Supports Black & White, Grayscale, RGB and Paletted images
-* Supports Fax 3 and Fax 4 (CCITT), JPEG, LZW, PackBits and other compressions (1,3,4,5,6,7,8,32773,32809)
-* E.g. [this 8 MPix image](//www.photopea.com/api/img/G4.TIF) with Fax 4 compression is just 56 kB ( [Open in Photopea](https://www.photopea.com?p=%7B%22files%22:%5B%22//www.photopea.com/api/img/G4.TIF%22%5D%7D) )
-
-## Installation
-
-Download and include the `UTIF.js` file in your code. If you're in NodeJS or otherwise using NPM, run:
-
-```sh
-npm install utif
-```
-
-#### `UTIF.decode(buffer)`
-* `buffer`: ArrayBuffer containing TIFF or EXIF data
-* returns an array of "IFDs" (image file directories). Each IFD is an object, keys are "tXYZ" (XYZ is a TIFF tag number), values are values of these tags. You can get the the dimension (and other properties, "metadata") of the image without decompressing pixel data.
-
-#### `UTIF.decodeImages(buffer, ifds)`
-* `buffer`: ArrayBuffer containing TIFF or EXIF data
-* `ifds`: the output of UTIF.decode()
-* loops through each IFD. If there is an image inside it, it is decoded and three new properties are added to the IFD:
-* * `width`: the width of the image
-* * `height`: the height of the image
-* * `data`: decompressed pixel data of the image
-
-TIFF files may have various number of channels and various color depth. The interpretation of `data` depends on many tags (see the [TIFF 6 specification](http://www.npes.org/pdf/TIFF-v6.pdf)). The following function converts any TIFF image into a 8-bit RGBA image.
-
-#### `UTIF.toRGBA8(ifd)`
-* `ifd`: image file directory (element of "ifds" returned by UTIF.decode(), processed by UTIF.decodeImages())
-* returns Uint8Array of the image in RGBA format, 8 bits per channel (ready to use in context2d.putImageData() etc.)
-
-### Example
-
-```javascript
-function imgLoaded(e) {
-  var ifds = UTIF.decode(e.target.response);
-  UTIF.decodeImages(e.target.response, ifds)
-  var rgba  = UTIF.toRGBA8(ifds[0]);  // Uint8Array with RGBA pixels
-  console.log(ifds[0].width, ifds[0].height, ifds[0]);
-}
-
-var xhr = new XMLHttpRequest();
-xhr.open("GET", "my_image.tif");
-xhr.responseType = "arraybuffer";
-xhr.onload = imgLoaded;   xhr.send();
-```
-## Use TIFF images in HTML
-
-If you are not a programmer, you can use TIFF images directly inside the `` element of HTML. Then, it is enough to call `UTIF.replaceIMG()` once at some point.
-
-#### `UTIF.replaceIMG()`
-```html
-
-...
-   ...
-```
-And UTIF.js will do the rest. Internally, an Image elements will be replaced by a Canvas elements. The attributes "id", "class" and "style" will be copied from the original Image to the new Canvas. Use CSS to style such images.
-
-
-## Encoding TIFF images
-
-You should not save images into TIFF format in the 21st century. Save them as PNG instead (e.g. using [UPNG.js](https://github.com/photopea/UPNG.js)). If you still want to use TIFF format for some reason, here it is.
-
-#### `UTIF.encodeImage(rgba, w, h, metadata)`
-* `rgba`: ArrayBuffer containing RGBA pixel data
-* `w`: image width
-* `h`: image height
-* `metadata` [optional]: IFD object (see below)
-* returns ArrayBuffer of the binary TIFF file. No compression right now.
-
-#### `UTIF.encode(ifds)`
-* `ifds`: array of IFDs (image file directories). An IFD is a JS object with properties "tXYZ" (where XYZ are TIFF tags)
-* returns ArrayBuffer of binary data. You can use it to encode EXIF data.
-
-## Dependencies
-TIFF format sometimes uses Inflate algorithm for compression (but it is quite rare). Right now, UTIF.js calls [Pako.js](https://github.com/nodeca/pako) for the Inflate method.
-TIFF format sometimes uses JPEG compression (but it is quite rare). Right now, UTIF.js calls "JpegDecoder" constructor, which comes from [pdf.js](https://github.com/mozilla/pdf.js). You can find it "separated" from pdf.js in libraries such as jpg.js.

+
+#### `UTIF.replaceIMG()`
+```html
+
+...
+   ...
+```
+And UTIF.js will do the rest. Internally, the "src" attribute of the image will be replaced with a new URI of the image (base64-encoded PNG). Note, that you can also insert DNG, CR2, NEF and other raw images into HTML this way.
+
+## Encoding TIFF images
+
+You should not save images into TIFF format in the 21st century. Save them as PNG instead (e.g. using [UPNG.js](https://github.com/photopea/UPNG.js)). If you still want to use TIFF format for some reason, here it is.
+
+#### `UTIF.encodeImage(rgba, w, h, metadata)`
+* `rgba`: ArrayBuffer containing RGBA pixel data
+* `w`: image width
+* `h`: image height
+* `metadata` [optional]: IFD object (see below)
+* returns ArrayBuffer of the binary TIFF file. No compression right now.
+
+#### `UTIF.encode(ifds)`
+* `ifds`: array of IFDs (image file directories). An IFD is a JS object with properties "tXYZ" (where XYZ are TIFF tags)
+* returns ArrayBuffer of binary data. You can use it to encode EXIF data.
+
+## Dependencies
+TIFF format sometimes uses Inflate algorithm for compression (but it is quite rare). Right now, UTIF.js calls [Pako.js](https://github.com/nodeca/pako) for the Inflate method.

+util-deprecate
+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();
+```

+# WebIDL Type Conversions on JavaScript Values
+
+This package implements, in JavaScript, the algorithms to convert a given JavaScript value according to a given [WebIDL](http://heycam.github.io/webidl/) [type](http://heycam.github.io/webidl/#idl-types).
+
+The goal is that you should be able to write code like
+
+```js
+const conversions = require("webidl-conversions");
+
+function doStuff(x, y) {
+    x = conversions["boolean"](x);
+    y = conversions["unsigned long"](y);
+    // actual algorithm code here
+}
+```
+
+and your function `doStuff` will behave the same as a WebIDL operation declared as
+
+```webidl
+void doStuff(boolean x, unsigned long y);
+```
+
+## API
+
+This package's main module's default export is an object with a variety of methods, each corresponding to a different WebIDL type. Each method, when invoked on a JavaScript value, will give back the new JavaScript value that results after passing through the WebIDL conversion rules. (See below for more details on what that means.) Alternately, the method could throw an error, if the WebIDL algorithm is specified to do so: for example `conversions["float"](NaN)` [will throw a `TypeError`](http://heycam.github.io/webidl/#es-float).
+
+## Status
+
+All of the numeric types are implemented (float being implemented as double) and some others are as well - check the source for all of them. This list will grow over time in service of the [HTML as Custom Elements](https://github.com/dglazkov/html-as-custom-elements) project, but in the meantime, pull requests welcome!
+
+I'm not sure yet what the strategy will be for modifiers, e.g. [`[Clamp]`](http://heycam.github.io/webidl/#Clamp). Maybe something like `conversions["unsigned long"](x, { clamp: true })`? We'll see.
+
+We might also want to extend the API to give better error messages, e.g. "Argument 1 of HTMLMediaElement.fastSeek is not a finite floating-point value" instead of "Argument is not a finite floating-point value." This would require passing in more information to the conversion functions than we currently do.
+
+## Background
+
+What's actually going on here, conceptually, is pretty weird. Let's try to explain.
+
+WebIDL, as part of its madness-inducing design, has its own type system. When people write algorithms in web platform specs, they usually operate on WebIDL values, i.e. instances of WebIDL types. For example, if they were specifying the algorithm for our `doStuff` operation above, they would treat `x` as a WebIDL value of [WebIDL type `boolean`](http://heycam.github.io/webidl/#idl-boolean). Crucially, they would _not_ treat `x` as a JavaScript variable whose value is either the JavaScript `true` or `false`. They're instead working in a different type system altogether, with its own rules.
+
+Separately from its type system, WebIDL defines a ["binding"](http://heycam.github.io/webidl/#ecmascript-binding) of the type system into JavaScript. This contains rules like: when you pass a JavaScript value to the JavaScript method that manifests a given WebIDL operation, how does that get converted into a WebIDL value? For example, a JavaScript `true` passed in the position of a WebIDL `boolean` argument becomes a WebIDL `true`. But, a JavaScript `true` passed in the position of a [WebIDL `unsigned long`](http://heycam.github.io/webidl/#idl-unsigned-long) becomes a WebIDL `1`. And so on.
+
+Finally, we have the actual implementation code. This is usually C++, although these days [some smart people are using Rust](https://github.com/servo/servo). The implementation, of course, has its own type system. So when they implement the WebIDL algorithms, they don't actually use WebIDL values, since those aren't "real" outside of specs. Instead, implementations apply the WebIDL binding rules in such a way as to convert incoming JavaScript values into C++ values. For example, if code in the browser called `doStuff(true, true)`, then the implementation code would eventually receive a C++ `bool` containing `true` and a C++ `uint32_t` containing `1`.

+The upside of all this is that implementations can abstract all the conversion logic away, letting WebIDL handle it, and focus on implementing the relevant methods in C++ with values of the correct type already provided. That is payoff of WebIDL, in a nutshell.
+
+And getting to that payoff is the goal of _this_ project—but for JavaScript implementations, instead of C++ ones. That is, this library is designed to make it easier for JavaScript developers to write functions that behave like a given WebIDL operation. So conceptually, the conversion pipeline, which in its general form is JavaScript values ↦ WebIDL values ↦ implementation-language values, in this case becomes JavaScript values ↦ WebIDL values ↦ JavaScript values. And that intermediate step is where all the logic is performed: a JavaScript `true` becomes a WebIDL `1` in an unsigned long context, which then becomes a JavaScript `1`.
+
+## Don't Use This
+
+Seriously, why would you ever use this? You really shouldn't. WebIDL is … not great, and you shouldn't be emulating its semantics. If you're looking for a generic argument-processing library, you should find one with better rules than those from WebIDL. In general, your JavaScript should not be trying to become more like WebIDL; if anything, we should fix WebIDL to make it more like JavaScript.
+
+The _only_ people who should use this are those trying to create faithful implementations (or polyfills) of web platform interfaces defined in WebIDL.

+
+[![OpenSSF Scorecard](https://api.securityscorecards.dev/projects/github.com/JakeChampion/fetch/badge)](https://securityscorecards.dev/viewer/?uri=github.com/JakeChampion/fetch)
+
+The `fetch()` function is a Promise-based mechanism for programmatically making
+web requests in the browser. This project is a polyfill that implements a subset
+of the standard [Fetch specification][], enough to make `fetch` a viable
+replacement for most uses of XMLHttpRequest in traditional web applications.

+
+## Read this first
+
+* If you believe you found a bug with how `fetch` behaves in your browser,
+  please **don't open an issue in this repository** unless you are testing in
+  an old version of a browser that doesn't support `window.fetch` natively.
+  Make sure you read this _entire_ readme, especially the [Caveats](#caveats)
+  section, as there's probably a known work-around for an issue you've found.
+  This project is a _polyfill_, and since all modern browsers now implement the
+  `fetch` function natively, **no code from this project** actually takes any
+  effect there. See [Browser support](#browser-support) for detailed
+  information.
+
+* If you have trouble **making a request to another domain** (a different
+  subdomain or port number also constitutes another domain), please familiarize
+  yourself with all the intricacies and limitations of [CORS][] requests.
+  Because CORS requires participation of the server by implementing specific
+  HTTP response headers, it is often nontrivial to set up or debug. CORS is
+  exclusively handled by the browser's internal mechanisms which this polyfill
+  cannot influence.
+
+* This project **doesn't work under Node.js environments**. It's meant for web
+  browsers only. You should ensure that your application doesn't try to package
+  and run this on the server.
+
+* If you have an idea for a new feature of `fetch`, **submit your feature
+  requests** to the [specification's repository](https://github.com/whatwg/fetch/issues).
+  We only add features and APIs that are part of the [Fetch specification][].
+
+## Installation
+
+```
+npm install whatwg-fetch --save
+```
+
+You will also need a Promise polyfill for [older browsers](https://caniuse.com/promises).
+We recommend [taylorhakes/promise-polyfill](https://github.com/taylorhakes/promise-polyfill)
+for its small size and Promises/A+ compatibility.
+
+## Usage
+
+### Importing
+
+Importing will automatically polyfill `window.fetch` and related APIs:
+
+```javascript
+import 'whatwg-fetch'
+
+window.fetch(...)
+```
+
+If for some reason you need to access the polyfill implementation, it is
+available via exports:
+
+```javascript
+import {fetch as fetchPolyfill} from 'whatwg-fetch'
+
+window.fetch(...)   // use native browser version
+fetchPolyfill(...)  // use polyfill implementation
+```
+
+This approach can be used to, for example, use [abort
+functionality](#aborting-requests) in browsers that implement a native but
+outdated version of fetch that doesn't support aborting.
+
+For use with webpack, add this package in the `entry` configuration option
+before your application entry point:
+
+```javascript
+entry: ['whatwg-fetch', ...]
+```
+
+### HTML
+
+```javascript
+fetch('/users.html')
+  .then(function(response) {
+    return response.text()
+  }).then(function(body) {
+    document.body.innerHTML = body
+  })
+```
+
+### JSON
+
+```javascript
+fetch('/users.json')
+  .then(function(response) {
+    return response.json()
+  }).then(function(json) {
+    console.log('parsed json', json)
+  }).catch(function(ex) {
+    console.log('parsing failed', ex)
+  })
+```
+
+### Response metadata
+
+```javascript
+fetch('/users.json').then(function(response) {
+  console.log(response.headers.get('Content-Type'))
+  console.log(response.headers.get('Date'))
+  console.log(response.status)
+  console.log(response.statusText)
+})
+```
+
+### Post form
+
+```javascript
+var form = document.querySelector('form')
+
+fetch('/users', {
+  method: 'POST',
+  body: new FormData(form)
+})
+```
+
+### Post JSON
+
+```javascript
+fetch('/users', {
+  method: 'POST',
+  headers: {
+    'Content-Type': 'application/json'
+  },
+  body: JSON.stringify({
+    name: 'Hubot',
+    login: 'hubot',
+  })
+})
+```
+
+### File upload
+
+```javascript
+var input = document.querySelector('input[type="file"]')
+
+var data = new FormData()
+data.append('file', input.files[0])
+data.append('user', 'hubot')
+
+fetch('/avatars', {
+  method: 'POST',
+  body: data
+})
+```
+
+### Caveats
+
+* The Promise returned from `fetch()` **won't reject on HTTP error status**
+  even if the response is an HTTP 404 or 500. Instead, it will resolve normally,
+  and it will only reject on network failure or if anything prevented the
+  request from completing.
+
+* For maximum browser compatibility when it comes to sending & receiving
+  cookies, always supply the `credentials: 'same-origin'` option instead of
+  relying on the default. See [Sending cookies](#sending-cookies).
+
+* Not all Fetch standard options are supported in this polyfill. For instance,
+  [`redirect`](#redirect-modes) and
+  `cache` directives are ignored.
+  
+* `keepalive` is not supported because it would involve making a synchronous XHR, which is something this project is not willing to do. See [issue #700](https://github.com/github/fetch/issues/700#issuecomment-484188326) for more information.
+
+#### Handling HTTP error statuses
+
+To have `fetch` Promise reject on HTTP error statuses, i.e. on any non-2xx
+status, define a custom response handler:
+
+```javascript
+function checkStatus(response) {
+  if (response.status >= 200 && response.status < 300) {
+    return response
+  } else {
+    var error = new Error(response.statusText)
+    error.response = response
+    throw error
+  }
+}
+
+function parseJSON(response) {
+  return response.json()
+}
+
+fetch('/users')
+  .then(checkStatus)
+  .then(parseJSON)
+  .then(function(data) {
+    console.log('request succeeded with JSON response', data)
+  }).catch(function(error) {
+    console.log('request failed', error)
+  })
+```
+
+#### Sending cookies
+
+For [CORS][] requests, use `credentials: 'include'` to allow sending credentials
+to other domains:
+
+```javascript
+fetch('https://example.com:1234/users', {
+  credentials: 'include'
+})
+```
+
+The default value for `credentials` is "same-origin".
+
+The default for `credentials` wasn't always the same, though. The following
+versions of browsers implemented an older version of the fetch specification
+where the default was "omit":
+
+* Firefox 39-60
+* Chrome 42-67
+* Safari 10.1-11.1.2
+
+If you target these browsers, it's advisable to always specify `credentials:
+'same-origin'` explicitly with all fetch requests instead of relying on the
+default:
+
+```javascript
+fetch('/users', {
+  credentials: 'same-origin'
+})
+```
+
+Note: due to [limitations of
+XMLHttpRequest](https://github.com/github/fetch/pull/56#issuecomment-68835992),
+using `credentials: 'omit'` is not respected for same domains in browsers where
+this polyfill is active. Cookies will always be sent to same domains in older
+browsers.
+
+#### Receiving cookies
+
+As with XMLHttpRequest, the `Set-Cookie` response header returned from the
+server is a [forbidden header name][] and therefore can't be programmatically
+read with `response.headers.get()`. Instead, it's the browser's responsibility
+to handle new cookies being set (if applicable to the current URL). Unless they
+are HTTP-only, new cookies will be available through `document.cookie`.
+
+#### Redirect modes
+
+The Fetch specification defines these values for [the `redirect`
+option](https://fetch.spec.whatwg.org/#concept-request-redirect-mode): "follow"
+(the default), "error", and "manual".
+
+Due to limitations of XMLHttpRequest, only the "follow" mode is available in
+browsers where this polyfill is active.
+
+#### Obtaining the Response URL
+
+Due to limitations of XMLHttpRequest, the `response.url` value might not be
+reliable after HTTP redirects on older browsers.
+
+The solution is to configure the server to set the response HTTP header
+`X-Request-URL` to the current URL after any redirect that might have happened.
+It should be safe to set it unconditionally.
+
+``` ruby
+# Ruby on Rails controller example
+response.headers['X-Request-URL'] = request.url
+```
+
+This server workaround is necessary if you need reliable `response.url` in
+Firefox < 32, Chrome < 37, Safari, or IE.
+
+#### Aborting requests
+
+This polyfill supports
+[the abortable fetch API](https://developers.google.com/web/updates/2017/09/abortable-fetch).
+However, aborting a fetch requires use of two additional DOM APIs:
+[AbortController](https://developer.mozilla.org/en-US/docs/Web/API/AbortController) and
+[AbortSignal](https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal).
+Typically, browsers that do not support fetch will also not support
+AbortController or AbortSignal. Consequently, you will need to include
+[an additional polyfill](https://www.npmjs.com/package/yet-another-abortcontroller-polyfill)
+for these APIs to abort fetches:
+
+```js
+import 'yet-another-abortcontroller-polyfill'
+import {fetch} from 'whatwg-fetch'
+
+// use native browser implementation if it supports aborting
+const abortableFetch = ('signal' in new Request('')) ? window.fetch : fetch
+
+const controller = new AbortController()
+
+abortableFetch('/avatars', {
+  signal: controller.signal
+}).catch(function(ex) {
+  if (ex.name === 'AbortError') {
+    console.log('request aborted')
+  }
+})
+
+// some time later...
+controller.abort()
+```
+
+## Browser Support
+
+- Chrome
+- Firefox
+- Safari 6.1+
+- Internet Explorer 10+
+
+Note: modern browsers such as Chrome, Firefox, Microsoft Edge, and Safari contain native
+implementations of `window.fetch`, therefore the code from this polyfill doesn't
+have any effect on those browsers. If you believe you've encountered an error
+with how `window.fetch` is implemented in any of these browsers, you should file
+an issue with that browser vendor instead of this project.

+# whatwg-url
+
+whatwg-url is a full implementation of the WHATWG [URL Standard](https://url.spec.whatwg.org/). It can be used standalone, but it also exposes a lot of the internal algorithms that are useful for integrating a URL parser into a project like [jsdom](https://github.com/tmpvar/jsdom).
+
+## Current Status
+
+whatwg-url is currently up to date with the URL spec up to commit [a62223](https://github.com/whatwg/url/commit/a622235308342c9adc7fc2fd1659ff059f7d5e2a).
+
+## API
+
+### The `URL` Constructor
+
+The main API is the [`URL`](https://url.spec.whatwg.org/#url) export, which follows the spec's behavior in all ways (including e.g. `USVString` conversion). Most consumers of this library will want to use this.
+
+### Low-level URL Standard API
+
+The following methods are exported for use by places like jsdom that need to implement things like [`HTMLHyperlinkElementUtils`](https://html.spec.whatwg.org/#htmlhyperlinkelementutils). They operate on or return an "internal URL" or ["URL record"](https://url.spec.whatwg.org/#concept-url) type.
+
+- [URL parser](https://url.spec.whatwg.org/#concept-url-parser): `parseURL(input, { baseURL, encodingOverride })`
+- [Basic URL parser](https://url.spec.whatwg.org/#concept-basic-url-parser): `basicURLParse(input, { baseURL, encodingOverride, url, stateOverride })`
+- [URL serializer](https://url.spec.whatwg.org/#concept-url-serializer): `serializeURL(urlRecord, excludeFragment)`
+- [Host serializer](https://url.spec.whatwg.org/#concept-host-serializer): `serializeHost(hostFromURLRecord)`
+- [Serialize an integer](https://url.spec.whatwg.org/#serialize-an-integer): `serializeInteger(number)`
+- [Origin](https://url.spec.whatwg.org/#concept-url-origin) [serializer](https://html.spec.whatwg.org/multipage/browsers.html#serialization-of-an-origin): `serializeURLOrigin(urlRecord)`
+- [Set the username](https://url.spec.whatwg.org/#set-the-username): `setTheUsername(urlRecord, usernameString)`
+- [Set the password](https://url.spec.whatwg.org/#set-the-password): `setThePassword(urlRecord, passwordString)`
+- [Cannot have a username/password/port](https://url.spec.whatwg.org/#cannot-have-a-username-password-port): `cannotHaveAUsernamePasswordPort(urlRecord)`
+
+The `stateOverride` parameter is one of the following strings:
+
+- [`"scheme start"`](https://url.spec.whatwg.org/#scheme-start-state)
+- [`"scheme"`](https://url.spec.whatwg.org/#scheme-state)
+- [`"no scheme"`](https://url.spec.whatwg.org/#no-scheme-state)
+- [`"special relative or authority"`](https://url.spec.whatwg.org/#special-relative-or-authority-state)
+- [`"path or authority"`](https://url.spec.whatwg.org/#path-or-authority-state)
+- [`"relative"`](https://url.spec.whatwg.org/#relative-state)
+- [`"relative slash"`](https://url.spec.whatwg.org/#relative-slash-state)
+- [`"special authority slashes"`](https://url.spec.whatwg.org/#special-authority-slashes-state)
+- [`"special authority ignore slashes"`](https://url.spec.whatwg.org/#special-authority-ignore-slashes-state)
+- [`"authority"`](https://url.spec.whatwg.org/#authority-state)
+- [`"host"`](https://url.spec.whatwg.org/#host-state)
+- [`"hostname"`](https://url.spec.whatwg.org/#hostname-state)
+- [`"port"`](https://url.spec.whatwg.org/#port-state)
+- [`"file"`](https://url.spec.whatwg.org/#file-state)
+- [`"file slash"`](https://url.spec.whatwg.org/#file-slash-state)
+- [`"file host"`](https://url.spec.whatwg.org/#file-host-state)
+- [`"path start"`](https://url.spec.whatwg.org/#path-start-state)
+- [`"path"`](https://url.spec.whatwg.org/#path-state)
+- [`"cannot-be-a-base-URL path"`](https://url.spec.whatwg.org/#cannot-be-a-base-url-path-state)
+- [`"query"`](https://url.spec.whatwg.org/#query-state)
+- [`"fragment"`](https://url.spec.whatwg.org/#fragment-state)
+
+The URL record type has the following API:
+
+- [`scheme`](https://url.spec.whatwg.org/#concept-url-scheme)
+- [`username`](https://url.spec.whatwg.org/#concept-url-username)
+- [`password`](https://url.spec.whatwg.org/#concept-url-password)
+- [`host`](https://url.spec.whatwg.org/#concept-url-host)
+- [`port`](https://url.spec.whatwg.org/#concept-url-port)
+- [`path`](https://url.spec.whatwg.org/#concept-url-path) (as an array)
+- [`query`](https://url.spec.whatwg.org/#concept-url-query)
+- [`fragment`](https://url.spec.whatwg.org/#concept-url-fragment)
+- [`cannotBeABaseURL`](https://url.spec.whatwg.org/#url-cannot-be-a-base-url-flag) (as a boolean)
+
+These properties should be treated with care, as in general changing them will cause the URL record to be in an inconsistent state until the appropriate invocation of `basicURLParse` is used to fix it up. You can see examples of this in the URL Standard, where there are many step sequences like "4. Set context object’s url’s fragment to the empty string. 5. Basic URL parse _input_ with context object’s url as _url_ and fragment state as _state override_." In between those two steps, a URL record is in an unusable state.
+
+The return value of "failure" in the spec is represented by the string `"failure"`. That is, functions like `parseURL` and `basicURLParse` can return _either_ a URL record _or_ the string `"failure"`.
