Я пытаюсь уменьшить мою реакцию JS Размер пакета

Question

Я пытаюсь уменьшить размер моего файла сборки (main. js 432 KiB), это небольшой виджет! Я пробовал сжатие-webpack-plugin и DefinePlugin , но напрасно, размер остался прежним, нужны ли мне эти два расширения, разделение кода не вариант, потому что это небольшой виджет с одним компонентом. Буду признателен за любые отзывы. Tks.

Ниже вы можете найти мой webpack.config. js

var webpack = require('webpack');
var path = require('path');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var CompressionPlugin = require('compression-webpack-plugin');

module.exports = {
  entry: ['@babel/polyfill', './app/index.js'],
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'main.js'
  },
  module: {
    rules: [
      { test: /\.(js)$/, use: 'babel-loader' },
      { test: /\.(css|scss)$/, use: [ 'style-loader', 'css-loader', 'sass-loader', 'cssimportant-loader' ] },
      { test: /\.(jpe?g|png|ttf|eot|svg|woff(2)?)(\?[a-z0-9=&.]+)?$/,   use: 'base64-inline-loader?limit=1000&name=[name].[ext]' }
    ]
  },
  devtool: 'source-map',
  plugins: [
    new HtmlWebpackPlugin({
      template: './app/index.html',
      minify: {
        collapseWhitespace: true
      }
    }),
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('production')
    }),
    new webpack.optimize.AggressiveMergingPlugin(),
    new CompressionPlugin({
      filename: "[path].gz[query]",
      algorithm: "gzip",
      test: /\.js$|\.css$|\.html$/,
      threshold: 10240,
      minRatio: 0.8
    })
  ]
};
