What Oxc is
Oxc is a free collection of JavaScript tools written in Rust for development workflows. It includes a linter, formatter, parser, transformer, resolver, minifier, and TypeScript runner, and is available for Linux, macOS, and Windows. Oxlint checks JavaScript and TypeScript, including JSX, TSX, and script blocks in Vue, Svelte, and Astro files. It has more than 870 rules covering areas such as TypeScript, React, Jest, Vitest, imports, Unicorn, and accessibility. Its type-aware linting uses tsgo, a native Go port of the TypeScript compiler. Oxfmt follows a Prettier-compatible workflow and can sort imports, Tailwind CSS classes, and package.json fields. Supported formats include JavaScript, TypeScript, JSON, YAML, TOML, HTML, Vue, Svelte, CSS, Markdown, and GraphQL. The transformer handles TypeScript and JSX, syntax lowering from ES2026 to ES2015, React Refresh, plugins, and isolated declaration emit. The experimental runner executes TypeScript and JSX without a separate build step, but does not type-check programs.
