SWC (Speedy Web Compiler) is a high-performance TypeScript/JavaScript compiler written in Rust. It provides both a Rust library and JavaScript bindings for parsing, transforming, and emitting modern JavaScript code.
Use cases
- Transpile modern TypeScript or JavaScript to older ECMAScript versions for browser compatibility
- Speed up build pipelines in tools like Next.js, Parcel, or Deno by replacing Babel
- Create custom code transformation plugins for JavaScript projects
- Bundle and minify JavaScript assets in a fast, Rust-powered workflow
- Run JavaScript/TypeScript compilation in a WebAssembly environment
When to choose
- You need a compiler that is significantly faster than Babel, especially for large codebases
- Your project is already using Rust or you want native performance in Node.js
- You require a library that can be used both from Rust and JavaScript/TypeScript
- You want to integrate custom transformation plugins written in Rust or JavaScript
When to avoid
- You need a full-featured bundler with advanced code-splitting and asset handling (SWC focuses on compilation)
- Your environment does not support native binaries or WebAssembly addons
- You rely on Babel-specific plugins that have no SWC equivalents
