Oxc: Next-Gen Rust tooling
summary
Oxc is a Rust-native toolchain that ships a parser, transpiler, resolver, linter, and build utilities and claims concrete speedups: 3× faster parser versus SWC (5× vs. Biome single-thread), a transpiler 3–4× faster, a resolver about 28× faster than Webpack Enhanced Resolve, and a linter 50–100× faster than ESLint. Implementation details include a handwritten lexer, bump allocator to minimize allocations, multithreaded linting, N-API bindings, DTS emission, and test suites from Test262, TypeScript, and Babel with ~95% coverage.
