  module: {
    loaders: [
      {
        test: /.s?css$/,
        use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader'],

        minimizerOptions: {
          // When we change these options, the hash of the asset should also change
          preset: ['default', { discardEmpty: false }],
        },
      })
    ],
  },
