使用 webpack 打包 express 应用

安装 webpack 依赖

pnpm add webpack webpack-cli -D

初始化配置

可以使用命令 webpack init 初始化配置或者直接自己创建 webpack.config.js 文件和增加 npm 脚本：
下面是 npm 脚本 和 webpack.config.js 配置：

// Generated using webpack-cli https://github.com/webpack/webpack-cli
const path = require("path");const isProduction = process.env.NODE_ENV == "production";const config = {entry: "./app.ts",output: {path: path.resolve(__dirname, "dist"),},plugins: [// Add your plugins here// Learn more about plugins from https://webpack.js.org/configuration/plugins/],target: "node",module: {rules: [{test: /\.(ts|tsx)$/i,loader: "ts-loader",exclude: ["/node_modules/"],},// Add your rules for custom modules here// Learn more about loaders from https://webpack.js.org/loaders/],},resolve: {extensions: [".tsx", ".ts", ".jsx", ".js", "..."],},
};module.exports = () => {if (isProduction) {config.mode = "production";} else {config.mode = "development";}return config;
};

npm 脚本配置：

"scripts": {"dev": "nodemon","build": "webpack --mode=development","build:dev": "webpack --mode=development","build:prod": "webpack --mode=production --node-env=production","watch": "webpack --watch","test": "echo \"Error: no test specified\" && exit 1"},
