How to import ruby gems (breakpoint) with webpack?

Question

I've installed susy and sass, and set up the css/sass loader in the webpack config:

{ test: /\.scss$/, loader: ExtractTextPlugin.extract('css!sass') }

Here is my main scss file:

@import "~susy/sass/susy";
@import "breakpoint";

$susy: (
  columns: 12,
  gutters: 1/4,
  math: fluid,
  output: float,
  gutter-position: inside
);

.layout {
  @include container();
  @include layout(12 1/4);
}

This is an error in a webpack output

ERROR in ./src/styles/base.scss
Module build failed: ModuleBuildError: Module build failed: 
@import "breakpoint";
^
      File to import not found or unreadable: breakpoint

Does anyone know how to properly @import breakpoint ?

Answer 1

Assuming you installed breakpoint-sass package:

npm install breakpoint-sass --save-dev

Then you have to import it, but "letting the SASS loader know" that this "breakpoint" element is outside the SASS folder, with the other node modules:

@import '~breakpoint-sass/stylesheets/breakpoint';

Answer 2

Take a look at the sass-loader import documentation:

The sass-loader uses node-sass' custom importer feature to pass all queries to the webpack resolving engine. Thus you can import your Sass modules from node_modules. Just prepend them with a ~ to tell webpack that this is not a relative import.

and

Writing @import "file" is the same as @import "./file".

pretty much describe the issue you're seeing.

Solution

The answer to this would be to either install a npm package for breakpoint instead of the gem and import it from node_modules, as you did with susy. Or you could try to @import the full file path to the ruby gem.
