项目打包

准备webpack

下载所有依赖的模块：

1	npm i webpack webpack-cli html-webpack-plugin css-loader html-loader copy-webpack-plugin mini-css-extract-plugin

配置命令 - package.json中：

{
  "name": "packproject",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "webpack"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "copy-webpack-plugin": "^11.0.0",
    "css-loader": "^6.7.3",
    "html-loader": "^4.2.0",
    "html-webpack-plugin": "^5.5.1",
    "mini-css-extract-plugin": "^2.7.5",
    "webpack": "^5.81.0",
    "webpack-cli": "^5.0.2"
  }
}

创建配置文件 - webpack.config.js

module.exports = {
    
}

准备项目

将前端项目copy过来

修改：

将index.html中除了index.js之外的js文件中的代码都放在index.js中

同理操作其他页面的js文件

html中引入的内容，都不引入了 - 创建单独的需要打包的js文件

在当前文件夹下新建config文件件，在其中新建了6个js文件：

index.js

cart.js

my.js

order.js

每个文件中单独引入html中需要的文件

index.js

import '../page/font/iconfont.css'
import '../page/css/index.css'

import '../page/js/index.js'

将html中的引入都删除

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">
    <title>首页</title>
</head>

其他文件同理

开始配置

const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')

module.exports = {
    // 入口
    entry: {
        index: './config/index.js',
        cart: './config/cart.js',
        login: './config/login.js',
        my: './config/my.js',
        order: './config/order.js',
        register: './config/register.js',
    },
    // 配置出口
    output: {
        path: path.join(__dirname, 'dist'),
        clean: true,
        assetModuleFilename: 'img/[name][ext]'
    },
    // 打包模式
    mode: 'production',
    // map文件
    devtool: 'source-map',
    // 配置插件
    plugins: [
        // 配置打包html的插件
        new HtmlWebpackPlugin({
            template: './page/index.html',
            chunks: ['index'],
            favicon: './page/favicon.ico',
            filename: 'index.html'
        }),
        new HtmlWebpackPlugin({
            template: './page/cart.html',
            chunks: ['cart'],
            favicon: './page/favicon.ico',
            filename: 'cart.html'
        }),
        new HtmlWebpackPlugin({
            template: './page/login.html',
            chunks: ['login'],
            favicon: './page/favicon.ico',
            filename: 'login.html'
        }),
        new HtmlWebpackPlugin({
            template: './page/my.html',
            chunks: ['my'],
            favicon: './page/favicon.ico',
            filename: 'my.html'
        }),
        new HtmlWebpackPlugin({
            template: './page/order.html',
            chunks: ['order'],
            favicon: './page/favicon.ico',
            filename: 'order.html'
        }),
        new HtmlWebpackPlugin({
            template: './page/register.html',
            chunks: ['register'],
            favicon: './page/favicon.ico',
            filename: 'register.html'
        }),
        // 配置拷贝uploads文件夹插件
        new CopyWebpackPlugin({
            patterns: [
                {
                    from: './page/uploads/',
                    to: 'uploads/'
                }
            ]
        }),
        // 配置css生成文件
        new MiniCssExtractPlugin({
            // 生成的文件名
            filename:'css/[name].css'
        }) 
    ],
    // 解析器
    module: {
        rules: [
            {
                test: /\.css/,
                use: [MiniCssExtractPlugin.loader, 'css-loader']
            },
            {
                test: /\.jpg$/,
                type: 'asset/resource' // webpack自带的静态资源处理
            },
            {
                test: /\.html$/,
                loader: 'html-loader'
            }
        ]
    }
}

执行打包命令，发现报错了，html写的不规范 - img标签的src不能为空，index.html中找到这个img标签，将src给一个图片链接

<!-- 商品详情 - 默认隐藏 -->
<div class="mask">
    <div class="detail">
        <img src="./uploads/1678345181467.png" alt="">
        <h4>商品名称</h4>
        <p>规格</p>
        <div class="spec">
            <p class="active">小份15个￥16.00</p>
            <p>大份20个￥21.00</p>
        </div>
        <div class="kind">
            <p class="active">干饺</p>
            <p>汤饺</p>
        </div>
        <div class="bottom">
            <span>总计</span>
            <span>￥16.00</span>
            <span class="addcart">+加入购物车</span>
        </div>
        <span class="iconfont icon-guanbi close"></span>
    </div>
</div>

继续打包，打包成功

运行打包后的项目

dist中的内容需要运行，跟之前的静态页面一样，需要服务器做静态资源托管，并设置服务器代理。

下载express和http-proxy-middleware

1	npm i express http-proxy-middleware

搭建服务器：

const express = require('express')
const {createProxyMiddleware} = require('http-proxy-middleware')

const app = express()
app.listen(3001)

app.use(express.static('dist'))

// 配置代理
const proxy = createProxyMiddleware({
    target: 'http://localhost:3000',
    changeOrigin: true
})

// 处理路由 - 上面静态资源处理不了路由
app.use((req, resp) => {
    proxy(req, resp)
})
