Linter (oxlint)

• 

Oxlint is designed to catch erroneous or useless code without requiring any configurations by default.

INFO

At the current stage, oxlint is not intended to fully replace ESLint; it serves as an enhancement when ESLint's slowness becomes a bottleneck in your workflow.

We recommend running oxlint before ESLint in your lint-staged or CI setup for a quicker feedback loop, considering it only takes a few seconds to run on large codebases.

Features

• 50 - 100 times faster than ESLint, and scales with the number of CPU cores (benchmark).
• Over 400 rules with a growing list from eslint, typescript, eslint-plugin-react, eslint-plugin-jest, eslint-plugin-unicorn, eslint-plugin-jsx-a11y and many more.
• Supports
  • .eslintignore.
  • ESLint comment disabling.
  • Partial ESLint v8 Configuration in json format

Language Support

• Supports:
  • JavaScript and TypeScript by their extensions js, mjs, cjs, jsx, ts, mts, cts and tsx.
  • <script> content of .vue, .astro and .svelte files.
• No support for:
  • type-aware rules defined by typescript-eslint.
  • stylistic rules.

Integration

ESLint

If you are looking for a way to use oxlint in projects that still need ESLint, You can use eslint-plugin-oxlint to turn off ESLint rules that are already supported by oxlint. So you can enjoy the speed of oxlint while still using ESLint.

lint-staged

{
  "lint-staged": {
    "**/*.{js,mjs,cjs,jsx,ts,mts,cts,tsx,vue,astro,svelte}": "oxlint"
  }
}

VSCode Extension

Download the official VSCode extension from the

• Visual Studio Marketplace
• Open VSX Registry

Continuous Integration

Since oxlint only takes a few seconds to run, we recommend running oxlint prior to ESLint for faster feedback loops.
