SWC (Speedy Web Compiler) is a super-fast TypeScript/JavaScript compiler written in Rust, usable as both a Rust library and a JavaScript package. It handles compilation, transformation, and minification of modern JS/TS code, and is embedded in tools like Next.js, Parcel, and Deno.

Use cases

• transpile typescript to javascript fast
• babel replacement for faster builds
• parse javascript or typescript into an AST
• speed up jest test transforms
• minify javascript bundles
• compile modern js for older browsers
• build custom javascript transforms in rust

When to choose

• you need a much faster alternative to Babel or tsc for transpilation
• you're building JS/TS tooling in Rust and need a parser or transform pipeline
• you use Next.js, Rspack, or webpack and want faster transforms via swc-loader

When to avoid

• you rely on Babel plugins with no SWC equivalent
• you need full TypeScript type-checking, which SWC does not perform
• you need a mature all-in-one bundler for complex production builds
