Oxc

Oxc, short for The JavaScript Oxidation Compiler, is described on its official site as a collection of high-performance JavaScript tools written in Rust. The suite includes a linter (Oxlint), a formatter (Oxfmt, in beta), a parser (oxc-parser), a transformer (oxc-transform), a resolver (oxc-resolver), and a minifier (oxc-minify, in alpha). The project states that it is free and open source and is made possible by sponsors.

The official Oxc website presents the project as The JavaScript Oxidation Compiler, a collection of high-performance JavaScript tools written in Rust. The site describes the project as the foundation of modern JavaScript tooling and states that Oxc is free and open source, made possible by sponsors. The homepage also announces React Compiler support.

Foundation of Modern JavaScript Tooling

• Oxlint

  ESLint-compatible linter that catches bugs before they make it to production; stated to be 50~100x faster than ESLint, with 800+ rules and growing, true type-aware linting powered by tsgo, and support for ESLint JS plugins.

• Oxfmt

  Prettier-compatible formatter (Beta) that enforces consistent code styles; stated to be 30x faster than Prettier and 3x faster than Biome, with Tailwind class sorting support.

• oxc-parser

  Parser described as the foundation for advanced transformations and compilations; stated to be 3x faster than SWC, parses .js(x) and .ts(x), and passes all Test262 stage4 tests.

• oxc-transform

  Transformer that transpiles source code; supports TypeScript & JSX syntax lowering to ES2015, Isolated Declarations DTS emit, React Fast Refresh, styled-components, and more.

• oxc-resolver

  Resolver for Node.js-compatible CJS and ESM module resolution; behavior aligned with enhanced-resolve, stated to be 28x faster than enhanced-resolve, and highly customizable.

• oxc-minify

  Minifier (Alpha) that compresses and optimizes code via dead code elimination, syntax shortening & whitespace removal, and variable name mangling.
