A pure JavaScript implementation of Sass. Sass makes CSS fun again.
|
|
|
This package is a distribution of Dart Sass, compiled to pure JavaScript
with no native code or external dependencies. It provides a command-line sass
executable and a Node.js API.
Usage
You can install Sass globally using npm install -g sass which will provide
access to the sass executable. You can also add it to your project using
npm install --save-dev sass. This provides the executable as well as a
library:
const sass = require('sass');
const result = sass.compile(scssFilename);
// OR
// Note that `compileAsync()` is substantially slower than `compile()`.
const result = await sass.compileAsync(scssFilename);
See the Sass website for full API documentation.
Legacy API
See Also
-
Dart Sass, from which this package is compiled, can be used either as a stand-alone executable or as a Dart library. Running Dart Sass on the Dart VM is substantially faster than running the pure JavaScript version, so this may be appropriate for performance-sensitive applications. The Dart API is also (currently) more user-friendly than the JavaScript API. See the Dart Sass README for details on how to use it.
-
Node Sass, which is a wrapper around LibSass, the C++ implementation of Sass. Node Sass supports the same API as this package and is also faster (although it's usually a little slower than Dart Sass). However, it requires a native library which may be difficult to install, and it's generally slower to add features and fix bugs.
