CSS parser, transformer, bundler and minifier written in Rust, usable from JavaScript, Rust or a standalone CLI.
lightningcss.devrepositorydocs
Lightning CSS is a CSS parser, transformer, bundler and minifier written in Rust. It is used from JavaScript through an npm package, from Rust as a library, or through a standalone command-line tool that compiles, minifies and bundles CSS files. Parcel includes it as its default CSS transformer. The project is maintained by Devon Govett and Parcel Contributors.
Worth knowing
The command-line tool is a separate npm package from the JavaScript library.
