sass-resources-loader

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!

Webpack V2?

If you are using Webpack v2, then please use 1.2.0-beta.1. Once Webpack v2 is out of beta, we will no longer be making updates for Webpack v1. Please see PR #16.

Installation

Get it via npm:

npm install sass-resources-loader

Usage

Create your file (or files) with resources:

/* resources.scss */

$section-width: 700px;

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

NB!

• Do not include anything that will be actually rendered in CSS, because it will be added to every imported SASS file.
• Do not use SASS @import inside resources files. Add imported files directly in sassResources array in webpack config instead.

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: [
        'style-loader',
        'css-loader',
        'postcss-loader',
        'sass-loader',
        {
          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' ]
