javascript – react-dom吹出webpack捆绑大小MASSIVELY

这一直是我遇到的webpack最奇怪的问题之一……

查看此捆绑细分：

反应116.01KB – 足够公平

react-dom 533.24KB – 认真的WTF

我认为它可能是我的依赖项中的损坏,但nuking node_modules并重新安装没有任何影响.我想这与webpack捆绑它的方式有关,但是我迷失了想法.我正在处理.js进口的方式是相当的股票标准.

// webpack.config.js
const path = require('path');
// const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const Dashboard = require('webpack-dashboard');
const DashboardPlugin = require('webpack-dashboard/plugin');

const dashboard = new Dashboard();

module.exports = {
  context: path.join(__dirname, 'src'),
  entry: {
    bundle: './index.js',
  },
  output: {
    filename: 'bundle.js',
    path: path.join(__dirname, 'build'),
  },
  module: {
    rules: [
      {
        test: /\.html$/,
        use: 'file-loader?name=[name].[ext]',
      },
      {
        test: /.scss$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [
            'css-loader',
            'postcss-loader',
          ],
        }),
      },
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: 'babel-loader',
      },
    ],
  },
  plugins: [
    // new BundleAnalyzerPlugin(),
    new ExtractTextPlugin('styles.css'),
    new DashboardPlugin(dashboard.setData),
  ],
  devServer: {
    quiet: true,
  },
};

// .babelrc
{
  "presets": [
    "react",
    "es2015"
  ],
  "plugins": ["transform-object-rest-spread"]
}

在v15.4.0中,react-dom的文件大小从1.17kB增加到619.05kB.这意味着我的webpack设置没有做任何错误的捆绑文件.这个模块变得如此庞大的原因是因为代码是从react模块传输的.
