This loader will @import your SASS resources into every required SASS module. So you can use your shared variables & mixins across all SASS styles without manually importing them in each file. Made to work with CSS Modules!

Note, this loader is not limited to SASS resources. It supposedly works with less, post-css, etc. per issue 31.

Version 1.3.3 and great supports Webpack 4.

If you're using this project and you like it, please give us a star! Thanks!

Get it via npm:

npm install sass-resources-loader


Create your file (or files) with resources:

/* resources.scss */

$section-width: 700px;

@mixin section-mixin {
  margin: 0 auto;
  width: $section-width;


  • Do not include anything that will be actually rendered in CSS, because it will be added to every imported SASS file.
  • Avoid using SASS @import rules inside resources files as it slows down incremental builds. Add imported files directly in sassResources array in webpack config instead. If you concerned about location of your resources index, you might want to check out the solution outlined in this comment.
  • If you still want to use SASS @imports make sure your paths are relative to the file they defined in (basically, your file with resources), except the ones started with ~ (~ is resolved to node_modules folder).

Apply loader in webpack config (v1.x.x & v2.x.x are supported) and provide path to the file with resources:

/* Webpack@2: webpack.config.js */

module: {
  rules: [
    // Apply loader
      test: /\.scss$/,
      use: [
          loader: 'sass-resources-loader',
          options: {
            // Provide path to the file with resources
            resources: './path/to/resources.scss',

            // Or array of paths
            resources: ['./path/to/vars.scss', './path/to/mixins.scss']

/* Webpack@1: webpack.config.js */

module: {
  loaders: [
    // Apply loader
    { test: /\.scss$/, loader: 'style!css!sass!sass-resources' },

// Provide path to the file with resources
sassResources: './path/to/resources.scss',

// Or array of paths
sassResources: ['./path/to/vars.scss', './path/to/mixins.scss'],

NOTE: If webpackConfig.context is not defined, process.cwd() will be used to resolve files with resource.

Now you can use these resources without manually importing them:

/* component.scss */

.section {
  @include section-mixin; // <--- `section-mixin` is defined here
import React from 'react';
import css from './component.scss';

// ...

render() {
  return (
    <div className={css.section} />

Glob pattern matching

You can specify glob patterns to match your all of your files in the same directory.

// Specify a single path
resources: './path/to/resources/**/*.scss', // will match all files in folder and subdirectories
// or an array of paths
resources: [ './path/to/resources/**/*.scss', './path/to/another/**/*.scss' ]

Note that sass-resources-loader will resolve your files in order. If you want your variables to be accessed across all of your mixins you should specify them in first place.

resources: [ './path/to/variables/vars.scss', './path/to/mixins/**/*.scss' ]
