title: Webpack 4: SCSS to CSS into separate file
body: <p>I would like to use Webpack 4 to transpile on one side my ES6 Javascript separately from my Sass:</p>
  
  <ul>
  <li>src/js/index.js → static/js/index.js</li>
  <li>src/css/style.scss → static/css/style.css</li>
  </ul>
  
  <p>Currently my webpack configuration seems to correctly transpile the javascript into a bundle.js but I cannot get my SCSS to transpile to CSS correctly. </p>
  
  <p>I would definitely try to debug somehow but since I'm very ignorant on Webpack internals I'm not sure how to do it. </p>
  
  <p>Following my webpack.config.js:</p>
  
  <pre><code>const ExtractTextPlugin = require('extract-text-webpack-plugin');
  const path = require('path');
  
  module.exports = {
  
    mode: 'development',
  
    entry: {
      bundle: './src/js/index.js',
    },
  
    output: {
      filename: '[name].js',
      path: path.resolve('static/js')
    },
  
    module: {
      rules: [{
        test: /\.scss$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [
            { loader: "css-loader" },     
            { 
              loader: "sass-loader",
              options: {
                includePaths: [
                  path.resolve("./src/css")
                ]
              }
            },
          ]
        }),
      }]
    },
  
    plugins: [
      new ExtractTextPlugin({
        filename: path.resolve('static/css/style.css')
      })
    ],
  }
  </code></pre>
