Snowpack is a modern, lightweight toolchain for faster web development. Traditional JavaScript build tools like webpack and Parcel need to rebuild & rebundle entire chunks of your application every time you save a single file. This rebundling step introduces lag between hitting save on your changes and seeing them reflected in the browser. Snowpack serves your application unbundled during development. Every file only needs to be built once and then is cached forever. When a file changes, Snowpack rebuilds that single file. There’s no time wasted re-bundling every change, just instant updates in the browser
