HtmlWebpackPlugin 不包含 vendor.js

Question

我正在努力提高我们网站的加载速度。所以我一直在努力 webpack.config.

经过多次修改后，我现在可以正确分离和散列模块。我还使用 HtmlWebpackPlugin 从模板中自动生成 index.html。

但我还遇到了其他一些问题。

vendor.js 不会自动添加到模板中。只有 chunk-manifest.json 和 index.[hash].js 会自动添加。如果我尝试像那样直接加载，我会得到

Uncaught ReferenceError: webpackJsonp is not defined

手动添加 vendor.js 后出现以下错误：

Uncaught ReferenceError: regeneratorRuntime is not defined

这是webpack.config:

const webpack = require('webpack');
const path = require('path');

const HtmlWebpackPlugin = require('html-webpack-plugin');
const ChunkManifestPlugin = require('chunk-manifest-webpack-plugin');
const WebpackChunkHash = require('webpack-chunk-hash');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

/* Shared Dev & Production */

const config = {
  context: path.resolve(__dirname, 'src'),

  entry: {
    index: './index.js',
    vendor: ['react', 'react-dom', 'react-router', 'react-redux', 'history', 'react-router-dom', 'redux', 'react-router-redux', 'redux-form', 'lodash'],
  },

  module: {
    rules: [
      {
        test: /\.js$/,
        use: 'babel-loader',
        exclude: /node_modules/,
      },
      {
        test: /\.(ico|jpg|png|gif|eot|otf|webp|svg|ttf|woff|woff2)(\?.*)?$/,
        exclude: /\/favicon.ico$/,
        use: [
        {
            loader: 'file-loader',
            query: {
              name: '[path][name][hash].[ext]',
              publicPath: '/'
            }
        }
        ]
      },
      {
        test: /\.css$/,
        include: path.join(__dirname, 'src/style'),
        use: [
          'style-loader',
          'css-loader'
        ]
      },
      {
        test: /\.(ico)(\?.*)?$/,
        exclude: /node_modules/,
        use: {
          loader: 'file-loader',
          options: { name: '[name].[ext]' },
        },
      },
      {
        test: /\.xml/,
        use: {
          loader: 'file-loader',
          options: { name: '[name].[ext]' },
        },
      },
    ],
  },

  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name].bundle.js',
    publicPath: '/',
  },

  resolve: {
    extensions: ['.js'],
    modules: [path.resolve(__dirname, 'src'), 'node_modules'],
  },

  plugins: [
    // New moment.js optimization
    new webpack.ContextReplacementPlugin(/moment[\/\]locale$/, /en/),

    new webpack.optimize.CommonsChunkPlugin({
            names: ['vendor'],
            filename: '[name].js',
            minChunks: Infinity
        }),

    new webpack.optimize.ModuleConcatenationPlugin(),

    new HtmlWebpackPlugin({
      appMountId: 'app-root',
      inlineManifestWebpackName: 'webpackManifest',
      template: 'templateIndex.html',
      title: 'Our Site',
    }),
  ],

  devServer: {
    historyApiFallback: true,
  },
};

//if (process.env.NODE_ENV !== 'production' && process.env.NODE_ENV !== 'test') {
  config.plugins = [
    ...config.plugins,
    new BundleAnalyzerPlugin({analyzerMode: 'static'}),
  ];
//}

//if (process.env.NODE_ENV === 'production') {
  config.output.filename = '[name].[chunkhash].js';
  config.plugins = [
    ...config.plugins,
    new webpack.HashedModuleIdsPlugin(),
    new WebpackChunkHash(),
    new ChunkManifestPlugin({
      filename: 'chunk-manifest.json',
      manifestVariable: 'webpackManifest',
      inlineManifest: true,
    }),
  ];
//}

module.exports = config;

此时我不确定 webpack.config 有什么问题。

如何让 vendor.js 自动添加？

这是模板：

<!doctype html>
<html lang="en">
<head>

  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

  <title itemprop="name">Our Site</title>

  <base href="/">

  <link type="image/png" href="/images/favicon.png" rel="icon">
  <link rel="icon" href="/images/favicon.ico" />
  <link rel="shortcut icon" href="/images/favicon.png" />

  <link rel="manifest" href="/manifest.webmanifest">

  <noscript>Your browser does not support JavaScript!</noscript>
</head>
<body>
  <div id="app"></div>
</body>
</html>

这是.babelrc（我认为regeneratorRuntime与它有关，只是需要弄清楚如何）

{
  "presets": [
    [
      "env",
      { "modules": false }
    ],
    "react",
    "stage-0",
    "stage-2"
  ],
  "plugins": [ "syntax-dynamic-import", "transform-react-jsx", "transform-decorators-legacy" ]
}

根据我在网上阅读的内容，再生器错误是由于包装冲突造成的。但我看不出这是从哪里来的。

Answer 1

根据我的经验：

Uncaught ReferenceError: webpackJsonp is not defined

通常是缺少由 CommonsChunkPlugin 提取的 Webpack 代码的结果。您可能还需要验证此文件是否已正确注入。

解决方案

我可以通过删除 ChunkManifestPlugin 使它正常工作。好像和CommonsChunkPlugin有冲突。我自己过去没有经历过的事情，但请查看我在下面所做的事情，它可以解决问题：

注意：您还需要包含 babel-polyfill 以使再生器运行时在浏览器中运行。

第一个：

巴别塔 6

npm install --save babel-polyfill

通天塔 7

npm install --save @babel/polyfill

然后：

差异：
