## @hey-api/openapi-ts 0.97.0

### ⚠️ Breaking

This release has 15 breaking changes. Please review the release notes carefully before upgrading.

### Updates

- cli: print file count and generator speed ([#3828](https://github.com/hey-api/openapi-ts/pull/3828))
- **⚠️ Breaking:** client: resolve `runtimeConfigPath` relative to the output folder ([#3770](https://github.com/hey-api/openapi-ts/pull/3770))

### Changed `runtimeConfigPath` behavior

This was a known, long-standing issue confusing first-time users. Before, defining client `runtimeConfigPath` value would paste it verbatim to the generated output. This release changes the behavior to resolve relative to the current working directory the same way output path works.
- config: remove `--apply` flag from Biome post-processor commands ([#3812](https://github.com/hey-api/openapi-ts/pull/3812))

    // ...other plugins
    {
      name: "sdk",
      validator: "valibot",
    },
    {

    {

This release has 1 breaking change. Please review the release notes carefully before upgrading.

### Updates

- **⚠️ Breaking:** symbol: replace `exportFrom` array with `getExportFromFilePath()` function ([#3322](https://github.com/hey-api/openapi-ts/pull/3322))

## @hey-api/openapi-ts 0.91.0

### ⚠️ Breaking

This release has 1 breaking change. Please review the release notes carefully before upgrading.

### Updates

- **⚠️ Breaking:** Drop CommonJS (CJS) support. This package is now **ESM-only**. ([#3251](https://github.com/hey-api/openapi-ts/pull/3251))

### Removed CommonJS (CJS) support

`@hey-api/openapi-ts` is now ESM-only. This change simplifies the codebase, improves tree-shaking, and enables better integration with modern bundlers and TypeScript tooling.

CommonJS entry points (`require()`, `module.exports`) are no longer supported. If you are in a CJS environment, you can still load the package dynamically using `import()` like:

```js
const { defineConfig } = await import("@hey-api/openapi-ts");
```

If you have previously written:

```js
const { defineConfig } = require("@hey-api/openapi-ts");
```

Migrate by updating your static imports:

```js
import { defineConfig } from "@hey-api/openapi-ts";
```

If your environment cannot use ESM, pin to a previous version.

# 2025-12-11

## @hey-api/openapi-ts 0.89.0

### Updates

- output: add `preferExportAll` option ([#2990](https://github.com/hey-api/openapi-ts/pull/2990))

### Prefer named exports

This release changes the default for `index.ts` to prefer named exports. Named exports may lead to better IDE and bundler performance compared to asterisk (`*`) as your tooling doesn't have to inspect the underlying module to discover exports.

While this change is merely cosmetic, you can set `output.preferExportAll` to `true` if you prefer to use the asterisk.

```js
export default {
  input: "hey-api/backend", // sign up at app.heyapi.dev
  output: {
    path: "src/client",
    preferExportAll: true,
  },
};
```
- output: add `nameConflictResolver` option ([#2990](https://github.com/hey-api/openapi-ts/pull/2990))

## Name Conflicts

As your project grows, the chances of name conflicts increase. We use a simple conflict resolver that appends numeric suffixes to duplicate identifiers. If you prefer a different strategy, you can provide your own `nameConflictResolver` function.

```js
export default {
  input: "hey-api/backend", // sign up at app.heyapi.dev
  output: {
    nameConflictResolver({ attempt, baseName }) {
      return attempt === 0 ? baseName : `${baseName}_N${attempt + 1}`;
    },
    path: "src/client",
  },
};
```

Example output:

```ts
export type ChatCompletion = string;

export type ChatCompletion_N2 = number;
```

### Removed `compiler` and `tsc` exports

This release removes the `compiler` utility functions. Instead, it introduces a new TypeScript DSL exposed under the `$` symbol. All plugins now use this interface, so you may notice slight changes in the generated output.

- feat(config): add `output.importFileExtension` option ([#2718](https://github.com/hey-api/openapi-ts/pull/2718))
- feat(pinia-colada): query options use `defineQueryOptions` ([#2610](https://github.com/hey-api/openapi-ts/pull/2610))

### Updated Pinia Colada query options

Pinia Colada query options now use `defineQueryOptions` to improve reactivity support. Instead of calling the query options function, you can use one of the [following approaches](https://heyapi.dev/openapi-ts/migrating#updated-pinia-colada-query-options).

#### No params

```ts
useQuery(getPetsQuery);
```

#### Constant

```ts
useQuery(getPetByIdQuery, () => ({
  path: {
    petId: 1,
  },
}));
```

#### Reactive

```ts
const petId = ref<number | null>(1);

useQuery(getPetByIdQuery, () => ({
  path: {
    petId: petId.value,
  },
}));
```

#### Properties

```ts
const petId = ref<number | null>(1);

useQuery(() => ({
  ...getPetByIdQuery({
    path: { petId: petId.value as number },
  }),
  enabled: () => petId.value !== null,
}));
```
- refactor(config): replace 'off' with null to disable options ([#2718](https://github.com/hey-api/openapi-ts/pull/2718))

### Updated `output` options

We made the `output` configuration more consistent by using `null` to represent disabled options. [This change](https://heyapi.dev/openapi-ts/migrating#updated-output-options) does not affect boolean options.

```js
export default {
  input: "hey-api/backend", // sign up at app.heyapi.dev
  output: {
    format: null,
    lint: null,
    path: "src/client",
    tsConfigPath: null,
  },
};
```

---

## @hey-api/openapi-ts 0.84.0

### Updates

- feat: Symbol API

### Symbol API

This release improves the Symbol API, which adds the capability to place symbols in arbitrary files. We preserved the previous output structure for all plugins except Angular.

You can preserve the previous Angular output by writing your own [placement function](https://heyapi.dev/openapi-ts/configuration/parser#hooks-symbols).

### Removed `output` plugin option

Due to the Symbol API release, this option has been removed from the Plugin API. ([#2664](https://github.com/hey-api/openapi-ts/pull/2664)) ([`e1ede9c`](https://github.com/hey-api/openapi-ts/commit/e1ede9cabf52b5bbcb9195570deff58db8f43dbb)) by [@mrlubos](https://github.com/mrlubos)
- fix(axios): remove duplicate `baseURL` when using relative values ([#2624](https://github.com/hey-api/openapi-ts/pull/2624))
- fix(config): add `output.fileName` option ([#2664](https://github.com/hey-api/openapi-ts/pull/2664))

## File Name

You can customize the naming and casing pattern for files using the `fileName` option.

```js
export default {
  input: "hey-api/backend", // sign up at app.heyapi.dev
  output: {
    fileName: "{{name}}",
    path: "src/client",
  },
};
```

By default, we append every file name with a `.gen` suffix to highlight it's automatically generated. You can customize or disable this suffix using the `fileName.suffix` option.

```js
export default {
  input: "hey-api/backend", // sign up at app.heyapi.dev
  output: {
    fileName: {
      suffix: ".gen",
    },
    path: "src/client",
  },
};
```

- fix(renderer): group and sort imported modules

### TypeScript renderer

We ship a dedicated TypeScript renderer for `.ts` files. This release improves the renderer's ability to group and sort imported modules, resulting in a more polished output. ([#2664](https://github.com/hey-api/openapi-ts/pull/2664)) ([`e1ede9c`](https://github.com/hey-api/openapi-ts/commit/e1ede9cabf52b5bbcb9195570deff58db8f43dbb)) by [@mrlubos](https://github.com/mrlubos)

## @hey-api/openapi-ts 0.83.0

### Updates

- feat: Symbol API

### Symbol API

This release adds the Symbol API, which significantly reduces the risk of naming collisions. While the generated output should only include formatting changes, this feature introduces breaking changes to the Plugin API that affect custom plugins.

We will update the [custom plugin guide](https://heyapi.dev/openapi-ts/plugins/custom) once the Plugin API becomes more stable. ([#2582](https://github.com/hey-api/openapi-ts/pull/2582)) ([`10aea89`](https://github.com/hey-api/openapi-ts/commit/10aea8910771ff72ef9b08d4eacdd6b028833c4c)) by [@mrlubos](https://github.com/mrlubos)
- feat(pinia-colada): remove `groupByTag` option

### Removed `groupByTag` Pinia Colada option

This option has been removed to provide a more consistent API across plugins. We plan to bring it back in a future release. ([#2582](https://github.com/hey-api/openapi-ts/pull/2582)) ([`10aea89`](https://github.com/hey-api/openapi-ts/commit/10aea8910771ff72ef9b08d4eacdd6b028833c4c)) by [@mrlubos](https://github.com/mrlubos)

### Updates

- Thanks [@SebastiaanWouters](https://github.com/SebastiaanWouters)! - feat(parser): add Hooks API ([#2505](https://github.com/hey-api/openapi-ts/pull/2505))

### Added Hooks API

This release adds the [Hooks API](https://heyapi.dev/openapi-ts/configuration/parser#hooks), giving you granular control over which operations generate queries and mutations. As a result, we tightened the previous behavior and POST operations no longer generate queries by default. To preserve the old behavior, add a custom matcher.

```js
export default {
  input: "hey-api/backend", // sign up at app.heyapi.dev
  output: "src/client",
  parser: {
    hooks: {
      operations: {
        isQuery: (op) => (op.method === "post" ? true : undefined),
      },
    },
  },
};

  ### Added Zod 4 and Zod Mini

  This release adds support for Zod 4 and Zod Mini. By default, the `zod` plugin will generate output for Zod 4. If you want to preserve the previous output for Zod 3 or use Zod Mini, set `compatibilityVersion` to `3` or `mini`.

  ```js
  export default {
    input: "hey-api/backend", // sign up at app.heyapi.dev
    output: "src/client",
    plugins: [
      // ...other plugins

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - fix(typescript): removed `typescript+namespace` enums mode ([#2284](https://github.com/hey-api/openapi-ts/pull/2284))

  ### Removed `typescript+namespace` enums mode

  Due to a simpler TypeScript plugin implementation, the `typescript+namespace` enums mode is no longer necessary. This mode was used in the past to group inline enums under the same namespace. With the latest changes, this behavior is no longer supported. You can either choose to ignore inline enums (default), or use the `enums` transform (added in v0.78.0) to convert them into reusable components which will get exported as usual.

# 2025-07-04

## @hey-api/openapi-ts 0.78.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat(config): add `parser` options ([#2246](https://github.com/hey-api/openapi-ts/pull/2246))

  ### Added `parser` options

  Previously, `@hey-api/typescript` would generate correct types, but the validator plugins would have to re-implement the same logic or generate schemas that didn't match the generated types.

  Since neither option was ideal, this release adds a dedicated place for `parser` options. Parser is responsible for preparing the input so plugins can generate more accurate output with less effort.

  You can learn more about configuring parser on the [Parser](https://heyapi.dev/openapi-ts/configuration/parser) page.

  ### Moved `input` options

  The following options were moved to the new `parser` group.

  - `input.filters` moved to `parser.filters`
  - `input.pagination` moved to `parser.pagination`
  - `input.patch` moved to `parser.patch`
  - `input.validate_EXPERIMENTAL` moved to `parser.validate_EXPERIMENTAL`

  ### Updated `typescript` options

  The following options were renamed.

  - `enumsCase` moved to `enums.case`
  - `enumsConstantsIgnoreNull` moved to `enums.constantsIgnoreNull`

  ### Moved `typescript` options

  The following options were moved to the new `parser` group.

  - `exportInlineEnums` moved to `parser.transforms.enums`
  - `readOnlyWriteOnlyBehavior` moved to `parser.transforms.readWrite.enabled`
  - `readableNameBuilder` moved to `parser.transforms.readWrite.responses.name`
  - `writableNameBuilder` moved to `parser.transforms.readWrite.requests.name`

  ### Updated `readWrite.responses` name

  Additionally, the naming pattern for response schemas has changed from `{name}Readable` to `{name}`. This is to prevent your code from breaking by default when using a schema that gets updated with a write-only field.
- Thanks [@mrlubos](https://github.com/mrlubos)! - fix(config): add `operations` option to `parser.patch` ([#2246](https://github.com/hey-api/openapi-ts/pull/2246))

  ### Updated Plugin API

  Please refer to the [custom plugin](https://heyapi.dev/openapi-ts/plugins/custom) tutorial for the latest guide.
- Thanks [@mrlubos](https://github.com/mrlubos)! - feat(sdk): update `validator` option ([#2227](https://github.com/hey-api/openapi-ts/pull/2227))

  ### Updated `sdk.validator` option

  Clients can now validate both request and response data. As a result, passing a boolean or string to `validator` will control both of these options. To preserve the previous behavior, set `validator.request` to `false` and `validator.response` to your previous configuration.

  ```js
  export default {
    input: "hey-api/backend", // sign up at app.heyapi.dev
    output: "src/client",
    plugins: [
      // ...other plugins
      {
        name: "@hey-api/sdk",
        validator: {
          request: false,
          response: true,
        },
      },
    ],
  };
  ```

# 2025-06-22

## @hey-api/openapi-ts 0.76.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat(valibot): generate a single schema for requests ([#2226](https://github.com/hey-api/openapi-ts/pull/2226))

  ### Single Valibot schema per request

  Previously, we generated a separate schema for each endpoint parameter and request body. In v0.76.0, a single request schema is generated for the whole endpoint. It may contain a request body, parameters, and headers.

  ```ts
  const vData = v.object({
    body: v.optional(
      v.object({
        foo: v.optional(v.string()),
        bar: v.optional(v.union([v.number(), v.null()])),
      })
    ),
    headers: v.optional(v.never()),
    path: v.object({
      baz: v.string(),
    }),
    query: v.optional(v.never()),
  });
  ```

  If you need to access individual fields, you can do so using the [`.entries`](https://valibot.dev/api/object/) API. For example, we can get the request body schema with `vData.entries.body`.
- Thanks [@mrlubos](https://github.com/mrlubos)! - fix(parser): prefer JSON media type ([#2221](https://github.com/hey-api/openapi-ts/pull/2221))

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat(parser): replace `plugin.subscribe()` with `plugin.forEach()` ([#2215](https://github.com/hey-api/openapi-ts/pull/2215))

  ### Added `plugin.forEach()` method

  This method replaces the `.subscribe()` method. Additionally, `.forEach()` is executed immediately, which means we don't need the `before` and `after` events – simply move your code before and after the `.forEach()` block.

  ```ts
  plugin.forEach("operation", "schema", (event) => {
    // do something with event
  });
  ```
- Thanks [@mrlubos](https://github.com/mrlubos)! - feat(tanstack-query): add name and case options ([#2218](https://github.com/hey-api/openapi-ts/pull/2218))

  ### Updated TanStack Query options

  The TanStack Query plugin options have been expanded to support more naming and casing patterns. As a result, the following options have been renamed.

  - `queryOptionsNameBuilder` renamed to `queryOptions`
  - `infiniteQueryOptionsNameBuilder` renamed to `infiniteQueryOptions`
  - `mutationOptionsNameBuilder` renamed to `mutationOptions`
  - `queryKeyNameBuilder` renamed to `queryKeys`
  - `infiniteQueryKeyNameBuilder` renamed to `infiniteQueryKeys`

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat(zod): generate a single schema for requests ([#2201](https://github.com/hey-api/openapi-ts/pull/2201))

  ### Single Zod schema per request

  Previously, we generated a separate schema for each endpoint parameter and request body. In v0.74.0, a single request schema is generated for the whole endpoint. It may contain a request body, parameters, and headers.

  ```ts
  const zData = z.object({
    body: z
      .object({
        foo: z.string().optional(),
        bar: z.union([z.number(), z.null()]).optional(),
      })
      .optional(),
    headers: z.never().optional(),
    path: z.object({
      baz: z.string(),
    }),
    query: z.never().optional(),
  });
  ```

  If you need to access individual fields, you can do so using the [`.shape`](https://zod.dev/api?id=shape) API. For example, we can get the request body schema with `zData.shape.body`.

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: bundle `@hey-api/client-*` plugins ([#2172](https://github.com/hey-api/openapi-ts/pull/2172))

  ### Bundle `@hey-api/client-*` plugins

  In previous releases, you had to install a separate client package to generate a fully working output, e.g. `npm install @hey-api/client-fetch`. This created a few challenges: getting started was slower, upgrading was sometimes painful, and bundling too. Beginning with v0.73.0, all Hey API clients are bundled by default and don't require installing any additional dependencies. You can remove any installed client packages and re-run `@hey-api/openapi-ts`.

  ```sh
  npm uninstall @hey-api/client-fetch
  ```

## @hey-api/openapi-ts 0.72.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat(sdk): add `classStructure` option supporting dot or slash `operationId` notation when generating class-based SDKs ([#2141](https://github.com/hey-api/openapi-ts/pull/2141))

  ### Added `sdk.classStructure` option

  When generating class-based SDKs, we now try to infer the ideal structure using `operationId` keywords. If you'd like to preserve the previous behavior, set `classStructure` to `off`.

  ```js
  export default {
    input: "hey-api/backend", // sign up at app.heyapi.dev
    output: "src/client",
    plugins: [
      // ...other plugins
      {
        classStructure: "off",
        name: "@hey-api/sdk",
      },
    ],
  };

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: upgraded input filters ([#2072](https://github.com/hey-api/openapi-ts/pull/2072))

  ### Upgraded input filters

  Input filters now avoid generating invalid output without requiring you to specify every missing schema as in the previous releases. As part of this release, we changed the way filters are configured and removed the support for regular expressions. Let us know if regular expressions are still useful for you and want to bring them back!

  ```js
  export default {
    input: {
      // match only the schema named `foo` and `GET` operation for the `/api/v1/foo` path
      filters: {
        operations: {
          include: ['GET /api/v1/foo'], // [!code ++]
        },
        schemas: {
          include: ['foo'], // [!code ++]
        },
      },
      include: '^(#/components/schemas/foo|#/paths/api/v1/foo/get)
  ```

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: respect `moduleResolution` value in `tsconfig.json` ([#2003](https://github.com/hey-api/openapi-ts/pull/2003))

  ### Respecting `moduleResolution` value in `tsconfig.json`

  This release introduces functionality related to your `tsconfig.json` file. The initial feature properly respects the value of your `moduleResolution` field. If you're using `nodenext`, the relative module paths in your output will be appended with `.js`. To preserve the previous behavior where we never appended `.js` to relative module paths, set `output.tsConfigPath` to `off`.

  ```js
  export default {
    input: "hey-api/backend", // sign up at app.heyapi.dev
    output: {
      path: "src/client",
      tsConfigPath: "off",
    },
  };
  ```

  ```js
  export default {
    input: "hey-api/backend", // sign up at app.heyapi.dev
    output: "src/client",

## @hey-api/openapi-ts 0.64.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: added `client.baseUrl` option ([#1661](https://github.com/hey-api/openapi-ts/pull/1661))

  ### Added `client.baseUrl` option

  You can use this option to configure the default base URL for the generated client. By default, we will attempt to resolve the first defined server or infer the base URL from the input path. If you'd like to preserve the previous behavior, set `baseUrl` to `false`.

  ```js
  export default {
    input: "path/to/openapi.json",
    output: "src/client",
    plugins: [
      {
        baseUrl: false, // [!code ++]
        name: "@hey-api/client-fetch",
      },
    ],
  };
  ```
- Thanks [@mrlubos](https://github.com/mrlubos)! - fix: make createConfig, CreateClientConfig, and Config accept ClientOptions generic ([#1661](https://github.com/hey-api/openapi-ts/pull/1661))

  ### Added `ClientOptions` interface

  The `Config` interface now accepts an optional generic extending `ClientOptions` instead of `boolean` type `ThrowOnError`.

  ```ts
  type Foo = Config<false>; // [!code --]
  type Foo = Config<{ throwOnError: false }>; // [!code ++]
  ```

## @hey-api/openapi-ts 0.63.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: move clients to plugins ([#1626](https://github.com/hey-api/openapi-ts/pull/1626))

  ### Client plugins

  Clients are now plugins generating their own `client.gen.ts` file. There's no migration needed if you're using CLI. If you're using the configuration file, move `client` options to `plugins`.

  ```js
  export default {
    client: "@hey-api/client-fetch", // [!code --]
    input: "path/to/openapi.json",
    output: "src/client",
    plugins: ["@hey-api/client-fetch"], // [!code ++]
  };
  ```
- Thanks [@mrlubos](https://github.com/mrlubos)! - fix: move sdk.throwOnError option to client.throwOnError ([#1626](https://github.com/hey-api/openapi-ts/pull/1626))

  ### Moved `sdk.throwOnError` option

  This SDK configuration option has been moved to the client plugins where applicable. Not every client can be configured to throw on error, so it didn't make sense to expose the option when it didn't have any effect.

  ```js
  export default {
    input: "path/to/openapi.json",
    output: "src/client",
    plugins: [
      {
        name: "@hey-api/client-fetch",
        throwOnError: true, // [!code ++]
      },
      {
        name: "@hey-api/sdk",
        throwOnError: true, // [!code --]
      },
    ],
  };
  ```
- Thanks [@mrlubos](https://github.com/mrlubos)! - fix: sdks import client from client.gen.ts instead of defining it inside the file ([#1626](https://github.com/hey-api/openapi-ts/pull/1626))

  ### Added `client.gen.ts` file

  The internal `client` instance previously located in `sdk.gen.ts` is now defined in `client.gen.ts`. If you're importing it in your code, update the import module.

  ```js
  import { client } from "client/sdk.gen"; // [!code --]
  import { client } from "client/client.gen"; // [!code ++]
  ```

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: add watch mode ([#1511](https://github.com/hey-api/openapi-ts/pull/1511))

  ## Watch Mode

  ::: warning
  Watch mode currently supports only remote files via URL.
  :::

  If your schema changes frequently, you may want to automatically regenerate the output during development. To watch your input file for changes, enable `watch` mode in your configuration or pass the `--watch` flag to the CLI.

  ### Config

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    watch: true,
  };
  ```

  ### CLI

  ```sh
  npx @hey-api/openapi-ts \
    -c @hey-api/client-fetch \
    -i path/to/openapi.json \
    -o src/client \
    -w

## @hey-api/openapi-ts 0.60.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - fix: require sdk.transformer to use generated transformers ([#1430](https://github.com/hey-api/openapi-ts/pull/1430))

  ### Added `sdk.transformer` option

  When generating SDKs, you now have to specify `transformer` in order to modify response data. By default, adding `@hey-api/transformers` to your plugins will only produce additional output. To preserve the previous functionality, set `sdk.transformer` to `true`.

  ```js
  import { defaultPlugins } from "@hey-api/openapi-ts";

  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    plugins: [
      ...defaultPlugins,
      {
        dates: true,
        name: "@hey-api/transformers",
      },
      {
        name: "@hey-api/sdk",
        transformer: true, // [!code ++]

    ],
  };

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: add `logs.level` option ([#1387](https://github.com/hey-api/openapi-ts/pull/1387))

  ### Added `logs.level` option

  You can now configure different log levels. As part of this feature, we had to introduce a breaking change by moving the `debug` option to `logs.level`. This will affect you if you're calling `@hey-api/openapi-ts` from Node.js (not CLI) or using the configuration file.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    debug: true, // [!code --]
    input: "path/to/openapi.json",
    logs: {
      level: "debug", // [!code ++]
    },
    output: "src/client",
  };
  ```
- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: remove `@hey-api/schemas` from default plugins ([#1389](https://github.com/hey-api/openapi-ts/pull/1389))

  ### Updated default `plugins`

  `@hey-api/schemas` has been removed from the default plugins. To continue using it, add it to your plugins array.

  ```js
  import { defaultPlugins } from "@hey-api/openapi-ts";

  export default {
    client: "@hey-api/client-fetch",
    experimentalParser: true,
    input: "path/to/openapi.json",
    output: "src/client",
    plugins: [
      ...defaultPlugins,
      "@hey-api/schemas", // [!code ++]
    ],
  };

# 2024-12-02

## @hey-api/openapi-ts 0.58.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: add typescript.identifierCase option ([#1353](https://github.com/hey-api/openapi-ts/pull/1353))

  ### Added `typescript.identifierCase` option

  **This change affects only the experimental parser.** By default, the generated TypeScript interfaces will follow the PascalCase naming convention. In the previous versions, we tried to preserve the original name as much as possible. To keep the previous behavior, set `typescript.identifierCase` to `preserve`.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    experimentalParser: true,
    input: "path/to/openapi.json",
    output: "src/client",
    plugins: [
      // ...other plugins
      {
        identifierCase: "preserve", // [!code ++]
        name: "@hey-api/typescript",
      },
    ],
  };
  ```
- Thanks [@mrlubos](https://github.com/mrlubos)! - fix: remove schemas and transformers re-exports from index.ts ([#1360](https://github.com/hey-api/openapi-ts/pull/1360))

  ### Removed `schemas.gen.ts` re-export

  `index.ts` will no longer re-export `schemas.gen.ts` to reduce the chance of producing broken output. Please update your code to import from `schemas.gen.ts` directly.

  ```js
  import { mySchema } from "client"; // [!code --]
  import { mySchema } from "client/schemas.gen"; // [!code ++]
  ```

  ### Removed `transformers.gen.ts` re-export

  `index.ts` will no longer re-export `transformers.gen.ts` to reduce the chance of producing broken output. Please update your code to import from `transformers.gen.ts` directly.

  ```js
  import { myTransformer } from "client"; // [!code --]
  import { myTransformer } from "client/transformers.gen"; // [!code ++]
  ```
- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: add output.clean option ([#1360](https://github.com/hey-api/openapi-ts/pull/1360))

  ### Added `output.clean` option

  By default, the `output.path` folder will be emptied on every run. To preserve the previous behavior, set `output.clean` to `false`.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: {
      clean: false, // [!code ++]
      path: "src/client",
    },
  };
  ```

# 2024-11-22

## @hey-api/openapi-ts 0.57.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: rename Hey API plugins ([#1324](https://github.com/hey-api/openapi-ts/pull/1324))

  ### Renamed `@hey-api/services` plugin

  This plugin has been renamed to `@hey-api/sdk`.

  ### Changed `sdk.output` value

  To align with the updated name, the `@hey-api/sdk` plugin will generate an `sdk.gen.ts` file. This will result in a breaking change if you're importing from `services.gen.ts`. Please update your imports to reflect this change.

  ```js
  import { client } from "client/services.gen"; // [!code --]
  import { client } from "client/sdk.gen"; // [!code ++]
  ```

  ### Renamed `@hey-api/types` plugin

  This plugin has been renamed to `@hey-api/typescript`.
- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: add typescript.exportInlineEnums option ([#1327](https://github.com/hey-api/openapi-ts/pull/1327))

  ### Added `typescript.exportInlineEnums` option

  By default, inline enums (enums not defined as reusable components in the input file) will be generated only as inlined union types. You can set `exportInlineEnums` to `true` to treat inline enums as reusable components. When `true`, the exported enums will follow the style defined in `enums`.

  This is a breaking change since in the previous versions, inline enums were always treated as reusable components. To preserve your current output, set `exportInlineEnums` to `true`. This feature works only with the experimental parser.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    experimentalParser: true,
    input: "path/to/openapi.json",
    output: "src/client",
    plugins: [
      // ...other plugins
      {
        exportInlineEnums: true, // [!code ++]
        name: "@hey-api/typescript",
      },
    ],
  };
  ```

- Thanks [@mrlubos](https://github.com/mrlubos)! - fix: forbid any body, path, or query parameters if not defined in spec ([#1237](https://github.com/hey-api/openapi-ts/pull/1237))

- Thanks [@mrlubos](https://github.com/mrlubos)! - fix: update schemas plugin to handle experimental 3.0.x parser ([#1233](https://github.com/hey-api/openapi-ts/pull/1233))

  This release adds an experimental parser for OpenAPI versions 3.0.x. In the future, this will become the default parser. If you're using OpenAPI 3.0 or newer, we encourage you to try it out today.

  You can enable the experimental parser by setting the `experimentalParser` boolean flag to `true` in your configuration file or CLI.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    experimentalParser: true,
  };
  ```

  ```sh
  npx @hey-api/openapi-ts -i path/to/openapi.json -o src/client -c @hey-api/client-fetch -e
  ```

  The generated output should not structurally change, despite few things being generated in a different order. In fact, the output should be cleaner! That's the immediate side effect you should notice. If that's not true, please leave feedback in [GitHub issues](https://github.com/hey-api/openapi-ts/issues).

  Hey API parser marks an important milestone towards v1 of `@hey-api/openapi-ts`. More features will be added to the parser in the future and the original parser from `openapi-typescript-codegen` will be deprecated and used only for generating legacy clients.

  If you'd like to work with the parser more closely (e.g. to generate code not natively supported by this package), feel free to reach out with any feedback or suggestions. Happy parsing! 🎉

## @hey-api/openapi-ts 0.54.0

### Updates

- Thanks [@mrlubos](https://github.com/mrlubos)! - feat: make plugins first-class citizens ([#1201](https://github.com/hey-api/openapi-ts/pull/1201))

  This release makes plugins first-class citizens. In order to achieve that, the following breaking changes were introduced.

  ### Removed CLI options

  The `--types`, `--schemas`, and `--services` CLI options have been removed. You can list which plugins you'd like to use explicitly by passing a list of plugins as `--plugins <plugin1> <plugin2>`

  ### Removed `*.export` option

  Previously, you could explicitly disable export of certain artifacts using the `*.export` option or its shorthand variant. These were both removed. You can now disable export of specific artifacts by manually defining an array of `plugins` and excluding the unwanted plugin.

  ::: code-group

  ```js [shorthand]
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    schemas: false, // [!code --]
    plugins: ["@hey-api/types", "@hey-api/services"], // [!code ++]
  };
  ```

  ```js [*.export]
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    schemas: {
      export: false, // [!code --]
    },
    plugins: ["@hey-api/types", "@hey-api/services"], // [!code ++]
  };
  ```

  :::

  ### Renamed `schemas.name` option

  Each plugin definition contains a `name` field. This was conflicting with the `schemas.name` option. As a result, it has been renamed to `nameBuilder`.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    schemas: {
      name: (name) => `${name}Schema`, // [!code --]
    },
    plugins: [
      // ...other plugins
      {
        nameBuilder: (name) => `${name}Schema`, // [!code ++]
        name: "@hey-api/schemas",
      },
    ],
  };
  ```

  ### Removed `services.include` shorthand option

  Previously, you could use a string value as a shorthand for the `services.include` configuration option. You can now achieve the same result using the `include` option.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    services: "^MySchema", // [!code --]
    plugins: [
      // ...other plugins
      {
        include: "^MySchema", // [!code ++]
        name: "@hey-api/services",
      },
    ],
  };
  ```

  ### Renamed `services.name` option

  Each plugin definition contains a `name` field. This was conflicting with the `services.name` option. As a result, it has been renamed to `serviceNameBuilder`.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    services: {
      name: "{{name}}Service", // [!code --]
    },
    plugins: [
      // ...other plugins
      {
        serviceNameBuilder: "{{name}}Service", // [!code ++]
        name: "@hey-api/services",
      },
    ],
  };
  ```

  ### Renamed `types.dates` option

  Previously, you could set `types.dates` to a boolean or a string value, depending on whether you wanted to transform only type strings into dates, or runtime code too. Many people found these options confusing, so they have been simplified to a boolean and extracted into a separate `@hey-api/transformers` plugin.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    types: {
      dates: "types+transform", // [!code --]
    },
    plugins: [
      // ...other plugins
      {
        dates: true, // [!code ++]
        name: "@hey-api/transformers",
      },
    ],
  };
  ```

  ### Removed `types.include` shorthand option

  Previously, you could use a string value as a shorthand for the `types.include` configuration option. You can now achieve the same result using the `include` option.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    types: "^MySchema", // [!code --]
    plugins: [
      // ...other plugins
      {
        include: "^MySchema", // [!code ++]
        name: "@hey-api/types",
      },
    ],
  };
  ```

  ### Renamed `types.name` option

  Each plugin definition contains a `name` field. This was conflicting with the `types.name` option. As a result, it has been renamed to `style`.

  ```js
  export default {
    client: "@hey-api/client-fetch",
    input: "path/to/openapi.json",
    output: "src/client",
    types: {
      name: "PascalCase", // [!code --]
    },
    plugins: [
      // ...other plugins
      {
        name: "@hey-api/types",
        style: "PascalCase", // [!code ++]
      },
    ],
  };
  ```
