## ⚓ 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](https://voidzero.dev/)'s vision for a unified, high-performance toolchain for JavaScript. It powers [Rolldown](https://rolldown.rs) ([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](https://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][docs-resolver-url] for module resolution. [Preact], [Shopify], [ByteDance], and [Shopee] use oxlint for linting.
