如何正确设置 webpack 配置以包含多页面（和条目）应用程序中使用的常见块？

Question

想象一下 html 文件的结构如下：

./home.html
./settings.html
./contact.html

还有下面的js文件

./nav.js <-- common - used in all html files
./home.js <-- used only in home.html, below follow the same rule
./settings.js
./contact.js

还有来自node_modules的一些模块：

"jquery" "moment"

在需要时被导入：

./home.js
import $ from "jquery";
(...)

我已经设置 webpack 将每个入口点作为每个文件名。现在如何在每个文件中包含常见的 js 文件，例如“./nav.js”？

entry: {
  home: "./resources/js/sections/home.js",
  settings: "./resources/js/sections/settings.js",
  (...)
} 
(...)
output: {
  filename: '[name].js',
}

// 选项A

像每个子页面中的另一个模块一样导入原始nav.js（home.js、contact.js、settings.js）

import nav from ./nav.js
nav();

// 选项 B

为 ./nav.js 创建另一个条目并手动将捆绑的 nav.js 添加到每个 html 以及其他捆绑的文件中。

entry: {
  (...)
  nav: "./resources/js/sections/nav.js"
}

您可以使用HtmlWebPackPlugin 将脚本动态附加到您的 HTML 页面。

首先安装插件：

npm install html-loader html-webpack-plugin --save-dev

然后使用配置：

const HtmlWebPackPlugin = require("html-webpack-plugin");

module.exports = {
  entry: {
    nav: './resources/js/sections/nav.js',
    home: './resources/js/sections/home.js',
    settings: './resources/js/sections/settings.js',
    contact: './resources/js/sections/contact.js',
  },
  output: {
    filename: '[name].js',
    path: path.resolve(__dirname, 'dist'), // folder where all tranformed files will be placed
  },
  rules: [
    {
      test: /\.html$/,
      use: [{ 
        loader: "html-loader", 
        options: { minimize: true } 
      }]
    }
  ],
  plugins: [
    // create an instance of HtmlWebPackPlugin for every page of a multipage website
    new HtmlWebPackPlugin({
      template: "./resources/html/home.html", // take html from this path
      filename: "./home.html", // name it 'home.html' and insert to the root of output folder
      chunks: ['nav', 'home'] // insert dymamically nav.js and home.js to home.html
    }),
    new HtmlWebPackPlugin({
      template: "./resources/html/settings.html",
      filename: "./settings.html",
      chunks: ['nav', 'settings']
    }),
    new HtmlWebPackPlugin({
      template: "./resources/html/contact.html",
      filename: "./contact.html",
      chunks: ['nav', 'contact']
    }),
  ]
}
