oxc-toolchain

name	oxc-toolchain
description	Set up oxlint (linting) + oxfmt (formatting) for JavaScript/TypeScript projects. Use when user asks to "migrate to oxlint", "switch to oxc", "use oxfmt", "set up oxlint", or wants to adopt the oxc toolchain for linting and formatting — whether migrating from ESLint, Biome, Prettier, or starting fresh.

oxc Toolchain Setup

Set up oxlint (linting) + oxfmt (formatting). oxfmt fully replaces Prettier — no Prettier fallback needed.

Supported File Types

oxfmt formats: JavaScript, JSX, TypeScript, TSX, JSON, JSONC, JSON5, YAML, TOML, HTML, Angular, Vue, CSS, SCSS, Less, Markdown, MDX, GraphQL, Ember, Handlebars

Built-in features that replace Prettier plugins: import sorting, Tailwind CSS class sorting, package.json field sorting, embedded formatting.

Setup Steps

1. Install packages: oxlint and oxfmt
2. Remove Prettier and its plugins if present (prettier, prettier-plugin-*, eslint-plugin-prettier, .prettierrc.*, .prettierignore)
3. Create .oxlintrc.json
4. Add scripts to package.json
5. Update VSCode settings to use oxc.oxc-vscode
6. Run format and lint to verify

When migrating from an existing linter (ESLint, Biome), remove the old packages and config files. oxlint uses ESLint-compatible rule names (kebab-case), so existing rule knowledge transfers directly.
