  },

  // [OPTIONAL] To enable sourcemaps, source-map-loader should be configured
  module: {
    rules: [
      {
        test: /\.js$/,
        include: path.resolve(__dirname, '../kotlin_build'),
        exclude: [
          /kotlin\.js$/, // Kotlin runtime doesn't have sourcemaps at the moment
        ],
        use: ['source-map-loader'],
        enforce: 'pre'
      }
    ]
