Including external dependencies that require stylesheets do not work.

I've tried using external libraries that require css files via require('someFile.css') result in errors like the following

ERROR in ../~/react-cropper/~/cropper/dist/cropper.css
Module parse failed: node_modules/react-cropper/node_modules/cropper/dist/cropper.css Line 10: Unexpected token .
You may need an appropriate loader to handle this file type.

| .cropper-container {
|   position: relative;
|   overflow: hidden;
 @ ../~/react-cropper/dist/react-cropper.js 21:0-35

Fixed by adding { test: /\.css$/, loader: ExtractTextPlugin.extract('style', 'css') } to webpack.config
