Sass.js is a JavaScript convenience API around libsass compiled to JavaScript with Emscripten, allowing SCSS/Sass compilation entirely in the browser via a web worker. It is intended for browser-based Sass compilation, while Node users are directed to node-sass or Dart Sass.
Use cases
- compile scss to css in the browser
- run sass compiler client-side without a server
- build an interactive sass playground in a web page
- compile sass in a web worker
- live-preview scss editing in a browser tool
- use libsass from javascript
When to choose
- you need to compile SCSS/Sass entirely client-side in the browser
- you're building an online Sass playground or live editor
- you can't run a server-side Sass build step
When to avoid
- you're compiling Sass in Node.js — use node-sass or Dart Sass instead
- you need the latest Sass features — libsass is deprecated in favor of Dart Sass
- payload size matters — the worker is ~4.5MB minified (~827KB gzipped)
