What do people build with it?

USE CASE 1

Run Oxlint to catch code quality issues in a JavaScript or TypeScript project without slow config overhead.

USE CASE 2

Speed up a Vite or Rolldown build pipeline by using Oxc as the underlying parser and transformer.

USE CASE 3

Replace existing JS linters or formatters with Oxc tools to cut CI pipeline time significantly.

In plain English

Oxc (The Oxidation Compiler) is a collection of high-performance JavaScript and TypeScript tools written in Rust. It aims to be significantly faster than equivalent JavaScript-based tools by leveraging Rust's performance characteristics. The toolset covers the main operations needed to build and ship JavaScript code: parsing, transformation (handling TypeScript, JSX, and modern JavaScript syntax), minification for smaller production bundles, module resolution, linting, and formatting. Oxc is part of the VoidZero project's vision for a unified JavaScript toolchain. It powers Rolldown, which is Vite's bundler, and is used in production by companies and projects including Nuxt, Preact, Shopify, ByteDance, and Shopee. The linter is called Oxlint and the formatter is called Oxfmt, both runnable without installation via npx. The project is open-source under the MIT license.

Copy-paste prompts

Prompt 1

I want to add Oxlint to my TypeScript project for fast linting. Show me how to set it up with npx and integrate it into my npm scripts.

Prompt 2

My Vite project uses Rolldown which is powered by Oxc. Help me understand how Oxc's transformer handles TypeScript and JSX compilation.

Prompt 3

Help me migrate my ESLint config to Oxlint, which rules have equivalents and what do I need to change in my CI workflow?

Prompt 4

Show me how to use the Oxc parser programmatically to parse a JavaScript file and traverse its AST.
