SWC
SWC (Speedy Web Compiler) is a fast, Rust-based JavaScript/TypeScript compiler and bundler designed for modern web development. It transforms and optimizes code, supporting features like JSX, TypeScript, and modern ECMAScript syntax, while offering significant performance improvements over traditional tools like Babel. It is commonly used for tasks such as transpilation, minification, and bundling in build pipelines.
Developers should use SWC when they need high-performance compilation and bundling for JavaScript or TypeScript projects, especially in large-scale applications where build speed is critical. It is ideal for frameworks like Next.js (which uses it by default) and React projects, as it reduces development feedback loops and improves CI/CD pipeline efficiency. SWC is also beneficial for teams adopting modern JavaScript features without sacrificing build performance.
