## Usage

### `Bundler Plugin`

Recommended the bundler plugin way to use the full `options` of `unplugin-oxlint`.

<details>
<summary>Vite</summary><br>

```ts
// vite.config.ts
import Oxlint from 'unplugin-oxlint/vite'

export default defineConfig({
  plugins: [Oxlint()],
})
```

<br></details>

<details>
<summary>Rollup</summary><br>

```ts
// rollup.config.js
import Oxlint from 'unplugin-oxlint/rollup'

export default {
  plugins: [Oxlint()],
}
```

<br></details>

<details>
<summary>esbuild</summary><br>

```ts
// esbuild.config.js
import { build } from 'esbuild'

build({
  plugins: [require('unplugin-oxlint/esbuild')()],
})
```

<br></details>

<details>
<summary>Webpack</summary><br>

```ts
// webpack.config.js
module.exports = {
  /* ... */
  plugins: [require('unplugin-oxlint/webpack')()],
}
```

<br></details>

### `Node.js API`

For cases that require execution in a Node.js environment, an API method is also provided to perform linting actions.

Tips: The Node.js API supports most `options` except for `watch`.

```ts
// scripts/lint.js
import { lint } from 'unplugin-oxlint'

lint({ includes: 'src/**/*.ts', glob: true })
```

If you're looking for a way to use `lint` in `scripts`.

```json
{
  "scripts": {
    "lint": "node scripts/lint.js"
  }
}
```

And the `lint` function can alse be used for creating integrations with other projects.

```ts
type Lint = (options: Omit<Options, 'watch'>) => Promise<LintResult[]>

interface LintResult {
  filename: string
  severity: 'off' | 'warning' | 'error'
  message: string
  linter: 'oxlint' | 'eslint'
  ruleId: string
}
```

## Playground

See [playground](./playground).

## ESLint

If you are looking for a way to use oxlint in projects that still need ESLint, You can use [eslint-plugin-oxlint](https://github.com/oxc-project/eslint-plugin-oxlint) to turn off ESLint rules that are already supported by oxlint.

The rules are extracted from [here](https://github.com/oxc-project/eslint-plugin-oxlint?tab=readme-ov-file)

`unplugin-oxlint` will automatically run the `eslint` script after `oxlint` when build start and file change.

```bash
# npm
npm i -D eslint eslint-plugin-oxlint

# pnpm
pnpm add -D eslint eslint-plugin-oxlint

# yarn
yarn add -D eslint eslint-plugin-oxlint
```

### Example

Use [eslint-plugin-oxlint](https://github.com/oxc-project/eslint-plugin-oxlint) with [@antfu/eslint-config](https://github.com/antfu/eslint-config)

```js
// eslint.config.js
import antfu from '@antfu/eslint-config'
import oxlint from 'eslint-plugin-oxlint'

export default [
  ...await antfu(),
  oxlint.configs['flat/all'],
]
```
