初始化

cd 項目名
webpack init

創建第二頁面與其頭文件

touch page2.html
touch src/page2.js

修改page2.js
console.log("success")

修改webpack.config.js
添加page2.html至plugins項，添加src/page2.js至entry項

最終模板:

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const WorkboxWebpackPlugin = require('workbox-webpack-plugin');

const isProduction = process.env.NODE_ENV == 'production';


const config = {
    entry: {
        main: './src/index.js',
        page2: './src/page2.jz'
    },
    output: {
        path: path.resolve(__dirname, 'dist'),
    },
    devServer: {
        open: true,
        host: 'localhost',
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: 'index.html',
            filename: 'index.html',
            chunks: ['main']
        }),
        HtmlWebpackPlugin({
            template: 'page2.html',
            filename: 'page2.html',
            chunks: ['page2']
        })
],
    module: {
        rules: [
            {
                test: /\.(eot|svg|ttf|woff|woff2|png|jpg|gif)$/i,
                type: 'asset',
            },
        ],
    },
};

module.exports = () => {
    if (isProduction) {
        config.mode = 'production';


        config.plugins.push(new WorkboxWebpackPlugin.GenerateSW());

    } else {
        config.mode = 'development';
    }
    return config;
};

運行webpack serve,進入網址: localhost:3000/page2.html
(根據實際配置自行更改)
打開控制枱有"success"輸出
