Sapper is a framework for building web applications of all sizes, with a beautiful development experience and flexible filesystem-based routing.

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.

Everything on npm, delivered directly to your browser.
