A Stylelint plugin for webpack


This module requires a minimum of Node v6.9.0 and webpack v4.0.0.

Differences With stylelint-loader

Both stylelint-loader and this module have their uses. stylelint-loader lints the files you require (or the ones you define as an entry in your webpack config). However, @imports in files are not followed, meaning only the main file for each require/entry is linted.

stylelint-webpack-plugin allows defining a glob pattern) matching the configuration and use of stylelint.

Getting Started

To begin, you'll need to install stylelint-webpack-plugin:

$ npm install stylelint-webpack-plugin --save-dev

Then add the plugin to your webpack config. For example:


import file from 'file.ext';
// webpack.config.js
const StyleLintPlugin = require('stylelint-webpack-plugin');

module.exports = {
  // ...
  plugins: [
    new StyleLintPlugin(options),
  // ...

And run webpack via your preferred method.


See stylelint's options for the complete list of options available. These options are passed through to the stylelint directly.


Type: String Default: undefined

Specify the config file location to be used by stylelint.

Note: By default this is handled by stylelint via cosmiconfig.


Type: String Default: compiler.context

A String indicating the root of your SCSS files.


Type: Boolean Default: true

If true, pipes stylelint error severity messages to the webpack compiler's error message handler.

Note: When this property is disabled all stylelint messages are piped to the webpack compiler's warning message handler.


Type: Boolean Default: false

If true, throws a fatal error in the global build process. This will end the build process on any stylelint error.


Type: String|Array[String] Default: '**/*.s?(a|c)ss'

Specify the glob pattern for finding files. Must be relative to options.context.


Type: Object Default: require('stylelint').formatters.string

Specify a custom formatter to format errors printed to the console.


Type: Boolean Default: false

Lint only changed files, skip lint on start.


Type: String Default: undefined

See the styelint user guide for more info. e.g. use 'scss' to lint .scss files.

Error Reporting

By default the plugin will dump full reporting of errors. Set failOnError to true if you want webpack build process breaking with any stylelint error. You can use the quiet option to avoid error output to the console.


This project was inspired by, and is a heavily modified version of sasslint-webpack-plugin.
