It can parse CSS into an Abstract Syntax Tree (AST) and convert the AST back to CSS with various formatting options. + +## Installation + +```bash +npm install @adobe/css-tools +``` + +## Core Functions + +### `parse(code, options?)` + +Parses CSS code and returns an Abstract Syntax Tree (AST). + +#### Parameters + +- `code` (string) - The CSS code to parse +- `options` (object, optional) - Parsing options + - `silent` (boolean) - Silently fail on parse errors instead of throwing. When `true`, errors are collected in `ast.stylesheet.parsingErrors` + - `source` (string) - File path for better error reporting + +#### Returns + +- `CssStylesheetAST` - The parsed CSS as an AST + +#### Example + +```javascript +import { parse } from '@adobe/css-tools'; + +const css = ` + .example { + color: red; + font-size: 16px; + } +`; + +const ast = parse(css); +console.log(ast.stylesheet.rules); +``` + +### `stringify(ast, options?)` + +Converts a CSS AST back to CSS string with configurable formatting. + +#### Parameters + +- `ast` (CssStylesheetAST) - The CSS AST to stringify +- `options` (CompilerOptions, optional) - Stringification options + - `indent` (string) - Indentation string (default: `' '`) + - `compress` (boolean) - Whether to compress/minify the output (default: `false`) + +#### Returns + +- `string` - The formatted CSS string + +#### Example + +```javascript +import { parse, stringify } from '@adobe/css-tools'; + +const css = '.example { color: red; }'; +const ast = parse(css); + +// Pretty print +const formatted = stringify(ast, { indent: ' ' }); +console.log(formatted); +// Output: +// .example { +// color: red; +// } + +// Compressed +const minified = stringify(ast, { compress: true }); +console.log(minified); +// Output: .example{color:red} +``` + +## Type Definitions + +### Core Types + +#### `CssStylesheetAST` +The root AST node representing a complete CSS stylesheet. + +```typescript +type CssStylesheetAST = { + type: CssTypes.stylesheet; + stylesheet: { + source?: string; + rules: CssRuleAST[]; + parsingErrors?: CssParseError[]; + }; +}; +``` + +#### `CssRuleAST` +Represents a CSS rule (selector + declarations). + +```typescript +type CssRuleAST = { + type: CssTypes.rule; + selectors: string[]; + declarations: CssDeclarationAST[]; + position?: CssPosition; + parent?: CssStylesheetAST; +}; +``` + +#### `CssDeclarationAST` +Represents a CSS property declaration. + +```typescript +type CssDeclarationAST = { + type: CssTypes.declaration; + property: string; + value: string; + position?: CssPosition; + parent?: CssRuleAST; +}; +``` + +#### `CssMediaAST` +Represents a CSS @media rule. + +```typescript +type CssMediaAST = { + type: CssTypes.media; + media: string; + rules: CssRuleAST[]; + position?: CssPosition; + parent?: CssStylesheetAST; +}; +``` + +#### `CssKeyframesAST` +Represents a CSS @keyframes rule. + +```typescript +type CssKeyframesAST = { + type: CssTypes.keyframes; + name: string; + keyframes: CssKeyframeAST[]; + position?: CssPosition; + parent?: CssStylesheetAST; +}; +``` + +#### `CssPosition` +Represents source position information. + +```typescript +type CssPosition = { + source?: string; + start: { + line: number; + column: number; + }; + end: { + line: number; + column: number; + }; +}; +``` + +#### `CssParseError` +Represents a parsing error. + +```typescript +type CssParseError = { + message: string; + reason: string; + filename?: string; + line: number; + column: number; + source?: string; +}; +``` + +### Compiler Options + +#### `CompilerOptions` +Options for the stringifier. + +```typescript +type CompilerOptions = { + indent?: string; // Default: ' ' + compress?: boolean; // Default: false +}; +``` + +## Error Handling + +### Silent Parsing + +When parsing malformed CSS, you can use the `silent` option to collect errors instead of throwing: + +```javascript +import { parse } from '@adobe/css-tools'; + +const malformedCss = ` + body { color: red; } + { color: blue; } /* Missing selector */ + .valid { background: green; } +`; + +const result = parse(malformedCss, { silent: true }); + +if (result.stylesheet.parsingErrors) { + result.stylesheet.parsingErrors.forEach(error => { + console.log(`Error at line ${error.line}: ${error.message}`); + }); +} + +// Valid rules are still parsed +console.log('Valid rules:', result.stylesheet.rules.length); +``` + +### Source Tracking + +Enable source tracking for better error reporting: + +```javascript +import { parse } from '@adobe/css-tools'; + +const css = 'body { color: red; }'; +const ast = parse(css, { source: 'styles.css' }); + +const rule = ast.stylesheet.rules[0]; +console.log(rule.position?.source); // "styles.css" +console.log(rule.position?.start); // { line: 1, column: 1 } +console.log(rule.position?.end); // { line: 1, column: 20 } +``` + +## Advanced Usage + +### Working with At-Rules + +```javascript +import { parse, stringify } from '@adobe/css-tools'; + +const css = ` + @media (max-width: 768px) { + .container { + padding: 10px; + } + } + + @keyframes fadeIn { + from { opacity: 0; } + to { opacity: 1; } + } +`; + +const ast = parse(css); + +// Access media rules +const mediaRule = ast.stylesheet.rules.find(rule => rule.type === 'media'); +console.log(mediaRule.media); // "(max-width: 768px)" + +// Access keyframes +const keyframesRule = ast.stylesheet.rules.find(rule => rule.type === 'keyframes'); +console.log(keyframesRule.name); // "fadeIn" +``` + +### Custom Formatting + +```javascript +import { parse, stringify } from '@adobe/css-tools'; + +const css = '.example{color:red;font-size:16px}'; +const ast = parse(css); + +// Custom indentation +const formatted = stringify(ast, { indent: ' ' }); +console.log(formatted); +// Output: +// .example { +// color: red; +// font-size: 16px; +// } + +// Compressed with no spaces +const compressed = stringify(ast, { compress: true }); +console.log(compressed); +// Output: .example{color:red;font-size:16px} +``` + +## TypeScript Integration + +The library provides comprehensive TypeScript support with full type definitions for all AST nodes and functions: + +```typescript +import { parse, stringify, type CssStylesheetAST } from '@adobe/css-tools';

It has been completely reworked to be easily extended and maintained. It is a right-to-left selector parser and compiler written in pure Javascript with no external dependencies. It was initially thought as a cross browser library to improve event delegation and web page scraping in various frameworks but it has become a popular replacement of the native CSS selection and matching functionality in newer browsers and headless environments. + +It uses [regular expressions](https://en.wikipedia.org/wiki/Regular_expression) to parse CSS selector strings and [metaprogramming](https://en.wikipedia.org/wiki/Metaprogramming) to transforms these selector strings into Javascript function resolvers. This process is executed only once for each selector string allowing memoization of the function resolvers and achieving unmatched performances. + +## Installation + +To include NWSAPI in a standard web page: + +```html + +``` + +To include NWSAPI in a standard web page and automatically replace the native QSA: + +```html + +``` + +To use NWSAPI with Node.js: + +``` +$ npm install nwsapi +``` + +NWSAPI currently supports browsers (as a global, `NW.Dom`) and headless environments (as a CommonJS module). + + +## Supported Selectors + +Here is a list of all the CSS2/CSS3/CSS4 [Supported selectors](https://github.com/dperini/nwsapi/wiki/CSS-supported-selectors). + + +## Features and Compliance + +You can read more about NWSAPI [features and compliance](https://github.com/dperini/nwsapi/wiki/Features-and-compliance) on the wiki. + + +## API + +### DOM Selection + +#### `ancestor( selector, context, callback )` + +Returns a reference to the nearest ancestor element matching `selector`, starting at `context`. Returns `null` if no element is found. If `callback` is provided, it is invoked for the matched element. + +#### `first( selector, context, callback )` + +Returns a reference to the first element matching `selector`, starting at `context`. Returns `null` if no element matches. If `callback` is provided, it is invoked for the matched element. + +#### `match( selector, element, callback )` + +Returns `true` if `element` matches `selector`, starting at `context`; returns `false` otherwise. If `callback` is provided, it is invoked for the matched element. + +#### `select( selector, context, callback )` + +Returns an array of all the elements matching `selector`, starting at `context`; returns empty `Array` otherwise. If `callback` is provided, it is invoked for each matching element. + + +### DOM Helpers + +#### `byId( id, from )` + +Returns a reference to the first element with ID `id`, optionally filtered to descendants of the element `from`. + +#### `byTag( tag, from )` + +Returns an array of elements having the specified tag name `tag`, optionally filtered to descendants of the element `from`. + +#### `byClass( class, from )` + +Returns an array of elements having the specified class name `class`, optionally filtered to descendants of the element `from`. + + +### Engine Configuration + +#### `configure( options )` + +The following is the list of currently available configuration options, their default values and descriptions, they are boolean flags that can be set to `true` or `false`: + +* `IDS_DUPES`: true - true to allow using multiple elements having the same id, false to disallow +* `LIVECACHE`: true - true for caching both results and resolvers, false for caching only resolvers +* `MIXEDCASE`: true - true to match tag names case insensitive, false to match using case sensitive +* `LOGERRORS`: true - true to print errors and warnings to the console, false to mute both of them + + +### Examples on extending the basic functionalities + +#### `configure( { : [ true | false ] } )` + +Disable logging errors/warnings to console, disallow duplicate ids. Example: + +```js +NW.Dom.configure( { LOGERRORS: false, IDS_DUPES: false } ); +``` +NOTE: NW.Dom.configure() without parameters return the current configuration. + +#### `registerCombinator( symbol, resolver )` + +Registers a new symbol and its matching resolver in the combinators table. Example: + +```js +NW.Dom.registerCombinator( '^', 'e.parentElement' ); +``` + +#### `registerOperator( symbol, resolver )` + +Registers a new symbol and its matching resolver in the attribute operators table. Example: + +```js +NW.Dom.registerOperator( '!=', { p1: '^', p2: '$', p3: 'false' } ); +``` + +#### `registerSelector( name, rexp, func )` + +Registers a new selector, the matching RE and the resolver function, in the selectors table. Example: + +```js +NW.Dom.registerSelector('Controls', /^\:(control)(.*)/i, + (function(global) { + return function(match, source, mode, callback) { + var status = true; + source = 'if(/^(button|input|select|textarea)/i.test(e.nodeName)){' + source + '}';

This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc. + +To enable `estree` mode simply add the plugin in the config: +```json +{ + "plugins": [ "estree" ] +} +``` + +If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned. + +Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew) + +Babylon exports a new function to parse a single expression + +```js +import { parseExpression } from 'babylon'; + +const ast = parseExpression('x || y && z', options); +``` + +The returned AST will only consist of the expression.

+ A family of specs for interoperable TypeScript +
+ standardschema.dev +

+
+ + + +The Standard Schema project is a set of interfaces that standardize the provision and consumption of shared functionality in the TypeScript ecosystem. + +Its goal is to allow tools to accept a single input that includes all the types and capabilities they need— no library-specific adapters, no extra dependencies. The result is an ecosystem that's fair for implementers, friendly for consumers, and open for end users. + +## The specifications + +The specifications can be found below in their entirety. Libraries wishing to implement a spec can copy/paste the code block below into their codebase. They're also available at `@standard-schema/spec` on [npm](https://www.npmjs.com/package/@standard-schema/spec) and [JSR](https://jsr.io/@standard-schema/spec). + +```ts +// ######################### +// ### Standard Typed ### +// ######################### + +/** The Standard Typed interface.

As a part of this goal, +you want your tests to avoid including implementation details of your components +and rather focus on making your tests give you the confidence for which they are +intended. As part of this, you want your testbase to be maintainable in the long +run so refactors of your components (changes to implementation but not +functionality) don't break your tests and slow you and your team down. + +## This Solution + +The `DOM Testing Library` is a very light-weight solution for testing DOM nodes +(whether simulated with [`JSDOM`](https://github.com/jsdom/jsdom) as provided by +default with [Jest][] or in the browser). The main utilities it provides involve +querying the DOM for nodes in a way that's similar to how the user finds +elements on the page. In this way, the library helps ensure your tests give you +confidence in your UI code. The `DOM Testing Library`'s primary guiding +principle is: + +> [The more your tests resemble the way your software is used, the more +> confidence they can give you.][guiding-principle] + +## Installation + +This module is distributed via [npm][npm] which is bundled with [node][node] and +should be installed as one of your project's `devDependencies`: + +``` +npm install --save-dev @testing-library/dom +``` + +> [**Docs**](https://testing-library.com/docs/install) + +## Documentation + +Read the docs (and discover framework and tool-specific implementations) at +[testing-library.com](https://testing-library.com/dom) + +## Guiding Principles + +> [The more your tests resemble the way your software is used, the more +> confidence they can give you.][guiding-principle] + +We try to only expose methods and utilities that encourage you to write tests +that closely resemble how your web pages are used. + +Utilities are included in this project based on the following guiding +principles: + +1. If it relates to rendering components, it deals with DOM nodes rather than + component instances, nor should it encourage dealing with component + instances. +2. It should be generally useful for testing the application components in the + way the user would use it. We _are_ making some trade-offs here because + we're using a computer and often a simulated browser environment, but in + general, utilities should encourage tests that use the components the way + they're intended to be used. +3. Utility implementations and APIs should be simple and flexible. + +At the end of the day, what we want is for this library to be pretty +light-weight, simple, and understandable. + +## Contributors + +Thanks goes to these people ([emoji key][emojis]): + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

The parsing detail level can be changed through [parser options](docs/parsing.md#parsesource-options), for example, you can disable parsing of selectors or declaration values for component parts. + +- **Tolerant to errors by design** + + Parser behaves as [spec says](https://www.w3.org/TR/css-syntax-3/#error-handling): "When errors occur in CSS, the parser attempts to recover gracefully, throwing away only the minimum amount of content before returning to parsing as normal". The only thing the parser departs from the specification is that it doesn't throw away bad content, but wraps it in a special node type (`Raw`) that allows processing it later. + +- **Fast and efficient** + + CSSTree is created with focus on performance and effective memory consumption. Therefore it's [one of the fastest CSS parsers](https://github.com/postcss/benchmark) at the moment. + +- **Syntax validation** + + The built-in lexer can test CSS against syntaxes defined by W3C. CSSTree uses [mdn/data](https://github.com/mdn/data/) as a basis for lexer's dictionaries and extends it with vendor specific and legacy syntaxes. Lexer can only check the declaration values and at-rules currently, but this feature will be extended to other parts of the CSS in the future. + +## Projects using CSSTree + +- [Svelte](https://github.com/sveltejs/svelte) – Cybernetically enhanced web apps +- [SVGO](https://github.com/svg/svgo) – Node.js tool for optimizing SVG files +- [CSSO](https://github.com/css/csso) – CSS minifier with structural optimizations +- [NativeScript](https://github.com/NativeScript/NativeScript) – NativeScript empowers you to access native APIs from JavaScript directly +- [react-native-svg](https://github.com/react-native-svg/react-native-svg) – SVG library for React Native, React Native Web, and plain React web projects +- [penthouse](https://github.com/pocketjoso/penthouse) – Critical Path CSS Generator +- [Bit](https://github.com/teambit/bit) – Bit is the platform for collaborating on components +- and more... + +## Documentation + +- [AST format](docs/ast.md) +- [Parsing CSS → AST](docs/parsing.md) + - [parse(source[, options])](docs/parsing.md#parsesource-options) +- [Serialization AST → CSS](docs/generate.md) + - [generate(ast[, options])](docs/generate.md#generateast-options) +- [AST traversal](docs/traversal.md) + - [walk(ast, options)](docs/traversal.md#walkast-options) + - [find(ast, fn)](docs/traversal.md#findast-fn) + - [findLast(ast, fn)](docs/traversal.md#findlastast-fn) + - [findAll(ast, fn)](docs/traversal.md#findallast-fn) +- [Util functions](docs/utils.md) + - Value encoding & decoding + - [property(name)](docs/utils.md#propertyname) + - [keyword(name)](docs/utils.md#keywordname) + - [ident](docs/utils.md#ident) + - [string](docs/utils.md#string) + - [url](docs/utils.md#url) + - [List class](docs/list.md) + - AST transforming + - [clone(ast)](docs/utils.md#cloneast) + - [fromPlainObject(object)](docs/utils.md#fromplainobjectobject) + - [toPlainObject(ast)](docs/utils.md#toplainobjectast) +- [Value Definition Syntax](docs/definition-syntax.md) + - [parse(source)](docs/definition-syntax.md#parsesource) + - [walk(node, options, context)](docs/definition-syntax.md#walknode-options-context) + - [generate(node, options)](docs/definition-syntax.md#generatenode-options) + - [AST format](docs/definition-syntax.md#ast-format) + +## Tools + +* [AST Explorer](https://astexplorer.net/#/gist/244e2fb4da940df52bf0f4b94277db44/e79aff44611020b22cfd9708f3a99ce09b7d67a8) – explore CSSTree AST format with zero setup +* [CSS syntax reference](https://csstree.github.io/docs/syntax.html) +* [CSS syntax validator](https://csstree.github.io/docs/validator.html) + +## Related projects + +* [csstree-validator](https://github.com/csstree/validator) – NPM package to validate CSS +* [stylelint-csstree-validator](https://github.com/csstree/stylelint-validator) – plugin for stylelint to validate CSS +* [Grunt plugin](https://github.com/sergejmueller/grunt-csstree-validator) +* [Gulp plugin](https://github.com/csstree/gulp-csstree) +* [Sublime plugin](https://github.com/csstree/SublimeLinter-contrib-csstree) +* [VS Code plugin](https://github.com/csstree/vscode-plugin) +* [Atom plugin](https://github.com/csstree/atom-plugin) + +## Usage + +Install with npm: + +``` +npm install css-tree +``` + +Basic usage: + +```js +import * as csstree from 'css-tree'; + +// parse CSS to AST +const ast = csstree.parse('.example { world: "!" }'); + +// traverse AST and modify it +csstree.walk(ast, (node) => { + if (node.type === 'ClassSelector' && node.name === 'example') { + node.name = 'hello'; + } +}); + +// generate CSS from AST +console.log(csstree.generate(ast)); +// .hello{world:"!"} +``` + +Syntax matching: + +```js +// parse CSS to AST as a declaration value +const ast = csstree.parse('red 1px solid', { context: 'value' }); + +// match to syntax of `border` property +const matchResult = csstree.lexer.matchProperty('border', ast); + +// check first value node is a +console.log(matchResult.isType(ast.children.first, 'color')); +// true + +// get a type list matched to a node +console.log(matchResult.getTrace(ast.children.first)); +// [ { type: 'Property', name: 'border' }, +// { type: 'Type', name: 'color' }, +// { type: 'Type', name: 'named-color' }, +// { type: 'Keyword', name: 'red' } ] +``` + +### Exports + +Is it possible to import just a needed part of library like a parser or a walker.
