⚓ Oxc

/oʊ ɛks siː/

The Oxidation Compiler is a collection of high-performance tools for JavaScript and TypeScript written in Rust.

Oxc is part of VoidZero's vision for a unified, high-performance toolchain for JavaScript. It powers Rolldown (Vite's bundler) and enables the next generation of ultra-fast development tools that work seamlessly together.

For more information, check out our website at oxc.rs.

_{* Oxidation is the chemical process that creates rust}

🙋 Who's using Oxc?

Rolldown and Nuxt use Oxc for parsing. Rolldown also uses Oxc for transformation and minification. Nova, swc-node, and knip use oxc_resolver for module resolution. Preact, Shopify, ByteDance, and Shopee use oxlint for linting.
