Node.js Webpack 4大小超过了推荐的限制(244 KiB)

我有两个组合在600字节(.6kb)以下的文件，如下所示.

那么，我的应用程序是如何运行的呢.捆js如此之大(987kb)，更重要的是，如何管理它的大小？

src文件索引.js

import _ from 'lodash';
import printMe from './print.js';


  function component() {
    var element = document.createElement('div');
    var btn = document.createElement('button');

    // Lodash, now imported by this script
    element.innerHTML = _.join(['Hello', 'webpack'], ' ');

    btn.innerHTML = 'click and check console';
    btn.onclick = printMe;

    element.appendChild(btn);

    return element;
  }

  document.body.appendChild(component());

src文件打印.js

export default function printMe() {
  consoe.log('Called from print.js');
}

网页包.配置.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');

module.exports = {
  entry: {
    app: './src/index.js',
    print:'./src/print.js'
  },
  devtool: 'inline-source-map',
  plugins: [
    new CleanWebpackPlugin(['dist']),
    new HtmlWebpackPlugin({
        title: 'Output Management'
    })
  ],
  output: {
    filename: '[name].bundle.js',
    path: path.resolve(__dirname, 'dist')
  }
};
