如何将 Webpack 4 SplitChunksPlugin 与 HtmlWebpackPlugin 一起用于多页面应用程序？

Question

我正在尝试利用 SplitChunksPlugin 为 MPA 中的每个 page/template 生成单独的包。当我使用 HtmlWebpackPlugin 时，每个页面都有一个 html 文件，其中有一个指向正确包的脚本标记。太棒了！但是，我遇到的麻烦是我的供应商文件。我希望单独的 html 文件仅指向他们需要的供应商包。当 SplitChunksPlugin 创建多个供应商包时，我无法让每个单独的 html 文件指向正确的供应商包。产生的包是：

home.bundle.js
product.bundle.js
cart.bundle.js
vendors~cart~home~product.bundle.js
vendors~cart~product.bundle.js

所以基本上主页模板应该引用 home.bundle.js、vendors~cart~home~product.bundle.js，而不是第二个 vendor bundle。只有购物车和产品模板应该引用这两个供应商包。我正在使用 HtmlWebpackPlugin 的 chunks 选项，但无法让它提取正确的供应商包，除非我像这样明确引用它的名称：

chunks: ['vendors~cart~home~product.bundle','home']

但这有点违背了动态呈现脚本标签的目的。我试过创建一个供应商入口点，但这会将我所有的供应商混在一起。是否缺少一些简单的配置？

我的webpack.config.js:

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

module.exports = {
    mode: 'development',
    devtool: 'cheap-module-eval-source-map',
    entry: {
        home: './src/js/page-types/home.js',
        product: './src/js/page-types/product.js',
        cart: './src/js/page-types/cart.js'
    },
    output: {
        filename: '[name].bundle.js',
        path: path.resolve(__dirname, 'dist/js')
    },
    optimization: {
        splitChunks: {
            chunks: 'all'
        }
    },
    plugins: [
        new CleanWebpackPlugin(['dist']),
        new Visualizer(),
        new HtmlWebpackPlugin({
            filename: 'home.html',
            chunks: ['vendors','home']
        }),
        new HtmlWebpackPlugin({
            filename: 'product.html',
            chunks: ['vendors','product']
        }),
        new HtmlWebpackPlugin({
            filename: 'cart.html',
            chunks: ['vendors~cart~product','cart']
        }),
    ], ...

我的 js 模块：

/* home.js */
    import jQuery from 'jquery';
    import 'bootstrap';

购物车和产品也引用了 React 库：

/* cart.js */
    import jQuery from 'jquery';
    import 'bootstrap';
    import React from 'react';
    import ReactDOM from 'react-dom';

/* product.js */
    import jQuery from 'jquery';
    import 'bootstrap';
    import React from 'react';
    import ReactDOM from 'react-dom';

示例 html 输出 home.html:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Webpack App</title>
  </head>
  <body>
  <script type="text/javascript" src="home.bundle.js"></script></body>
</html>

一种选择是手动创建供应商块，然后在 HtmlWebpackPlugin 的 chunks 选项中包含页面所需的任何块。

webpack.config.js:

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

module.exports = {
    mode: 'development',
    devtool: 'cheap-module-eval-source-map',
    entry: {
        home: './src/js/page-types/home.js',
        product: './src/js/page-types/product.js',
        cart: './src/js/page-types/cart.js'
    },
    output: {
        filename: '[name].bundle.js',
        path: path.resolve(__dirname, 'dist/js')
    },
    optimization: {
        splitChunks: {
            cacheGroups: {
                'vendor-bootstrap': {
                    name: 'vendor-bootstrap',
                    test: /[\/]node_modules[\/](jquery|bootstrap)[\/]/,
                    chunks: 'initial',
                    priority: 2
                },
                'vendor-react': {
                    name: 'vendor-react',
                    test: /[\/]node_modules[\/]react.*?[\/]/,
                    chunks: 'initial',
                    priority: 2
                },
                'vendor-all': {
                    name: 'vendor-all',
                    test: /[\/]node_modules[\/]/,
                    chunks: 'initial',
                    priority: 1
                },
            }
        }
    },
    plugins: [
        new CleanWebpackPlugin(['dist']),
        new Visualizer(),
        new HtmlWebpackPlugin({
            filename: 'home.html',
            chunks: ['vendor-bootstrap', 'vendor-all', 'home']
        }),
        new HtmlWebpackPlugin({
            filename: 'product.html',
            chunks: ['vendor-bootstrap', 'vendor-react', 'vendor-all', 'product']
        }),
        new HtmlWebpackPlugin({
            filename: 'cart.html',
            chunks: ['vendor-bootstrap', 'vendor-react', 'vendor-all', 'cart']
        }),
    ], ...

vendor-all 块用于捕获未包含在其他块中的任何其他供应商库。

使用版本4的html-webpack-plugin（目前处于测试阶段），并且只在chunks选项中包含入口chunk。

npm i -D html-webpack-plugin@next

和

module.exports = {
    new HtmlWebpackPlugin({
        filename: 'home.html',
        chunks: ['home']
    }),
    new HtmlWebpackPlugin({
        filename: 'product.html',
        chunks: ['product']
    }),
    new HtmlWebpackPlugin({
        filename: 'cart.html',
        chunks: ['cart']
    }),
};

这将自动包含相关块。
