grunt-contrib-sass v2.0.0 Build Status: Linux Build Status: Windows

Compile Sass to CSS

Getting Started

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-contrib-sass --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


Sass task

Run this task with the grunt sass command.

Sass is a preprocessor that adds nested rules, variables, mixins and functions, selector inheritance, and more to CSS. Sass files compile into well-formatted, standard CSS to use in your site or application.

This task requires you to have Ruby and Sass installed. If you're on OS X or Linux you probably already have Ruby installed; test with ruby -v in your terminal. When you've confirmed you have Ruby installed, run gem install sass to install Sass.

Note: Files that begin with "_" are ignored even if they match the globbing pattern. This is done to match the expected Sass partial behaviour.

  • auto - relative paths where possible, file URIs elsewhere

Example config

  sass: {                              // Task
    dist: {                            // Target
      options: {                       // Target options
        style: 'expanded'
      files: {                         // Dictionary of files
        'main.css': 'main.scss',       // 'destination': 'source'
        'widgets.css': 'widgets.scss'
grunt.registerTask('default', ['sass']);


  sass: {
    dist: {
      files: {
        'main.css': 'main.scss'

Concat and compile

Instead of concatenating the files, just @import them into another .sass file eg. main.scss.

Compile multiple files

You can specify multiple destination: source items in files.

  sass: {
    dist: {
      files: {
        'main.css': 'main.scss',
        'widgets.css': 'widgets.scss'

Compile files in a directory

Instead of naming all files you want to compile, you can use the expand property allowing you to specify a directory. More information available in the grunt docs - Building the files object dynamically.

  sass: {
    dist: {
      files: [{
        expand: true,
        cwd: 'styles',
        src: ['*.scss'],
        dest: '../public',
        ext: '.css'
