Webpack怎么打包JS全栈项目_Webpack配置与JS全栈项目打包详细步骤

const path = require('path');

module.exports = [
  // 前端打包配置
  {
    mode: 'production',
    entry: './client/index.js',
    output: {
      path: path.resolve(__dirname, 'dist/client'),
      filename: 'bundle.js'
    },
    target: 'web',
    module: {
      rules: [
        {
          test: /\.js$/,
          exclude: /node_modules/,
          use: 'babel-loader'
        },
        {
          test: /\.css$/,
          use: ['style-loader', 'css-loader']
        }
      ]
    }
  },

  // 后端打包配置
  {
    mode: 'production',
    entry: './server/index.js',
    output: {
      path: path.resolve(__dirname, 'dist/server'),
      filename: 'server.js'
    },
    target: 'node',
    externals: [/^node:.*/, 'express'], // 排除 Node 原生模块和 express 等依赖
    module: {
      rules: [
        {
          test: /\.js$/,
          exclude: /node_modules/,
          use: 'babel-loader'
        }
      ]
    },
    resolve: {
      extensions: ['.js']
    },
    node: {
      __dirname: false,
      __filename: false
    }
  }
];

npm install --save-dev webpack webpack-cli babel-loader @babel/core @babel/preset-env css-loader style-loader

{
  "presets": ["@babel/preset-env"]
}

"scripts": {
  "build": "webpack",
  "start": "node dist/server/server.js"
}

resolve: {
  modules: [path.resolve(__dirname, 'shared'), 'node_modules']
}
