sass-extract-loader

Webpack loader for sass-extract.

Require sass files as modules containing the variables defined in those files. Supports @include directives for extracting variables across multiple files.

This does not replace the sass-loader for requiring sass in order to generate css, but serves as an additional tool in order to use variables defined in sass in your javascript modules.

Install

You need to install the sass compiler, sass-extract and the loader since they are all peer dependencies.

npm install --save node-sass sass-extract sass-extract-loader

Usage

Recommended

The recommended usage is to use the loader explicitly when requiring .sass or .scss files since you are likely to have separate loader for generating the css for your app from the same sass files.

const style = require('sass-extract-loader!./style.scss');

/*
style ==> {
  global: {
    $variable: <value>
    ..
  }
}
*/

Alternative

You can add the loader in your webpack configuration file as expected.

{
  module: {
    loaders: [
      {
        test: /\.scss$/,
        loader: 'sass-extract-loader'
      }
    ]
  }
}

Note that this alternative might not be a good choice as you likely want the default behavior of requiring a sass files to be generating css from it. However, you might have a case when you want to use certain files as runtime variables to be handled by the sass-extract-loader by default.

{
  module: {
    loaders: [
      {
        test: /\.runtime\.scss$/,
        loader: 'sass-extract-loader'
      }
    ]
  }
}

The resulting module will be a plain JSON object containing the extracted variables and their values. For detailed documentation on the structure and semantics of the response head over to the documentation for sass-extract.

Options

All options available for node-sass can be passed to the loader with any of the available methods for webpack.

An example is including a path for resolving imports such as const styleVariables = require('sass-extract-loader?{"includePaths": ["./foobar"]}!./style.scss');.

Plugins

Plugins can be used by passing plugin module names in the query options to the loader const styleVariables = require('sass-extract-loader?{"plugins": ["minimal"]}!./style.scss');.
