Sass is a mature CSS preprocessor language that extends CSS with variables, nested rules, mixins, functions, and selector inheritance, compiled to standard CSS. The sass/sass repository hosts the language specification and proposals, with the primary implementation being Dart Sass, distributed as a standalone CLI, a Dart library, and the pure-JavaScript sass / sass-embedded npm packages.
Use cases
- compile scss to css
- use variables and mixins in stylesheets
- organize large css codebases with nesting and partials
- integrate sass compilation into a webpack or vite build
- programmatically compile sass from node.js or dart
- share design tokens across projects with sass functions
When to choose
- you want a battle-tested, fully-featured CSS preprocessor with active development
- you need a fast standalone CLI or embeddable JS/Dart API for compiling stylesheets
- your project already uses .scss/.sass files and needs the reference implementation
When to avoid
- you only need plain modern CSS, since native CSS now supports variables and nesting
- you rely on LibSass or node-sass, which are deprecated and no longer receive new features
- you want a utility-first or component-scoped styling approach rather than a preprocessor
