eslint-plugin-oxlint

Turn off all rules already supported by oxlint. The rules are extracted from here.

What is oxlint?

See https://oxc.rs/blog/2023-12-12-announcing-oxlint.html

Installation

pnpm add eslint-plugin-oxlint --D

Usage

Flat config

This plugin is optimized for flat config usage (eslint >= 9.0). See here for more details.

Example:

// eslint.config.js
import oxlint from 'eslint-plugin-oxlint';
export default [
  ...// other plugins
  oxlint.configs['flat/recommended'], // oxlint should be the last one
];

Legacy config

If you are using legacy configuration (eslint < 9.0), you can use the following config:

// .eslintrc.js
module.exports = {
  ... // other config
  extends: [
    ... // other presets
    "plugin:oxlint/recommended",
  ],
}

Detect rules from oxlint.json

If you are using flat configuration (eslint >= 9.0), you can use the following config:

// eslint.config.js
import oxlint from 'eslint-plugin-oxlint';
export default [
  ..., // other plugins
  ...oxlint.buildFromOxlintConfigFile('./oxlint.json'),
];

Or build it by an oxlint.json-like object:

// eslint.config.js
import oxlint from 'eslint-plugin-oxlint';
export default [
  ..., // other plugins
  ...oxlint.buildFromOxlintConfig({
    categories: {
      correctness: 'warn'
    },
    rules: {
      eqeqeq: 'warn'
    }
  }),
];

buildFromOxlintConfigFile is not supported for legacy configuration (eslint < 9.0).

Run it before eslint

And then you can add the following script to your package.json:

{
  "scripts": {
    "lint": "npx oxlint && npx eslint"
  }
}
