Lint your .scss files

Getting Started

This plugin requires Grunt >= 0.4.0 and scss-lint >= 0.18.0. It is recommended to use the scss_lint gem as that is the currently maintained version.

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-scss-lint --save-dev

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


Scss-lint task

Run this task with the grunt scsslint command.

scss-lint is a Ruby gem written by The Causes Engineering Team. It is currently owned and maintained by brigade. This plugin is simply a grunt wrapper for the gem.

This task requires you to have Ruby, and scss-lint 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 update --system && gem install scss_lint to install the scss_lint gem.



  • Type: Boolean
  • Default: false

You can choose to have your gems installed via bundler and if so, set this option to true to use the local gems.


  • Type: Boolean
  • Default: true

Get some nice looking output.

For colors to work on Windows, you first need to install 2 extra gems. This is because of Rainbow, a dependency of scss-lint.

gem install windows-pr win32console


  • Type: Boolean
  • Default: false

Group related linted files for more easier error review. XML output will still be default from scss-lint.


  • Type: String
  • Default: node_modules/grunt-scss-lint/.scss-lint.yml.

Specify a configuration file.


  • Type: String
  • Default: null.

Specify a gem version for the scsslint gem.


  • Type: String or Array
  • Default: null

Exclude one or more files from being linted.


  • Type: String
  • Default: null

The file to save the output to. If you don't want this then set the option as null.


  • Type: String
  • Default: null
  • Options: txt, xml

This will ultimately default to the file extension used for reporterOutput if left null


  • Type: Boolean
  • Default: false

Emits a Grunt event on scss-lint error called scss-lint-error.


  • Type: Boolean
  • Default: false

Emits a Grunt event on scss-lint success called scss-lint-success.


  • Type: Boolean
  • Default: true

Disable to fail the task only on errors. You can set the severity level for individual linters in your configuration file.


  • Type: Boolean
  • Default: false

Set force to true to report scss-lint warnings and errors but not fail the task. This overrides failOnWarning.


  • Type: Number or Boolean
  • Default: 300 * 1024

Set maxBuffer for the child_process.exec process, if you're linting a lot of files and you're recieving no output then you can try and increase this value. Setting it to false, 0, NaN or Infinite will not return any stdout or stderr and the task will think that everything's fine.

Usage Examples

Example config

  scsslint: {
    allFiles: [
    options: {
      bundleExec: true,
      config: '.scss-lint.yml',
      reporterOutput: 'scss-lint-report.xml',
      colorizeOutput: true


grunt.registerTask('default', ['scsslint']);

Exit error codes
