本文介紹了如何使用Vue3和Vite搭建多項(xiàng)目環(huán)境,并在打包時(shí)生成多個(gè)dist包,通過(guò)創(chuàng)建主項(xiàng)目環(huán)境、配置多個(gè)dist包、以及執(zhí)行打包操作,可以實(shí)現(xiàn)多個(gè)子項(xiàng)目的獨(dú)立管理

1. 創(chuàng)建一個(gè)主項(xiàng)目環(huán)境

使用命令，快速創(chuàng)建一個(gè)住項(xiàng)目的環(huán)境

npm create vue@latest

2. 子項(xiàng)目目錄

3. 子項(xiàng)目文件

在兩個(gè)子項(xiàng)目中分別創(chuàng)建App.vue和main.js文件

我這里的代碼直接使用vue創(chuàng)建時(shí)的代碼，需要改的地方是資源，文件的路徑

App.vue

```javascript
<script setup>
import { RouterLink, RouterView } from 'vue-router'
import HelloWorld from '../../components/HelloWorld.vue'
</script>

<template>
  <header>
    <img alt="Vue logo" class="logo" src="../../assets/logo.svg" width="125" height="125" />

    <div class="wrapper">
      <HelloWorld msg="You did it!" />

      <nav>
        <RouterLink to="/">Home</RouterLink>
        <RouterLink to="/about">About</RouterLink>
      </nav>
    </div>
  </header>

  <RouterView />
</template>

<style scoped>
header {
  line-height: 1.5;
  max-height: 100vh;
}

.logo {
  display: block;
  margin: 0 auto 2rem;
}

nav {
  width: 100%;
  font-size: 12px;
  text-align: center;
  margin-top: 2rem;
}

nav a.router-link-exact-active {
  color: var(--color-text);
}

nav a.router-link-exact-active:hover {
  background-color: transparent;
}

nav a {
  display: inline-block;
  padding: 0 1rem;
  border-left: 1px solid var(--color-border);
}

nav a:first-of-type {
  border: 0;
}

@media (min-width: 1024px) {
  header {
    display: flex;
    place-items: center;
    padding-right: calc(var(--section-gap) / 2);
  }

  .logo {
    margin: 0 2rem 0 0;
  }

  header .wrapper {
    display: flex;
    place-items: flex-start;
    flex-wrap: wrap;
  }

  nav {
    text-align: left;
    margin-left: -1rem;
    font-size: 1rem;

    padding: 1rem 0;
    margin-top: 1rem;
  }
}
</style>

main.js

import '../../assets/main.css'

import { createApp } from 'vue'
import { createPinia } from 'pinia'

import App from './App.vue'
import router from '../../router'

const app = createApp(App)

app.use(createPinia())
app.use(router)

app.mount('#app')

然后在于index.html同級(jí)的地方添加兩個(gè)對(duì)應(yīng)子項(xiàng)目的html，如果項(xiàng)目的title，圖標(biāo)一致，可以直接用index.html，不需要新建html文件

projecta.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <link rel="icon" href="/favicon.ico" rel="external nofollow" >
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>項(xiàng)目Ap</title>
  </head>
  <body>
    <div id="app"></div>
    <script type="module" src="/src/projects/projectA/main.js"></script>
  </body>
</html>

4. 配置多個(gè) dist 包

新建projectConfig.js，存放子項(xiàng)目的入口配置

export const configMap = {
    projectA:{
      minify: true,
      pages: [
          {
              filename: 'projecta', // filename 默認(rèn)是template文件名，就是beijing.html
              entry: 'src/projects/projectA/main.js',
              template: 'projecta.html',
          },   
      ],
    },
    projectB:{
      minify: true,
      pages: [
          {
              filename: 'projectb',
              entry: 'src/projects/proiectB/main.js',
              template: 'projectb.html',
          },
      ],
    }
  }

然后修改vite.config.js如下：

import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { createHtmlPlugin } from 'vite-plugin-html';
import { resolve } from 'node:path';
import { configMap } from './projectConfig'

const projectName = process.env.PROJECT_NAME
export default defineConfig({
    base: './',             // 方便打包后預(yù)覽
    publicDir: 'public',    // 默認(rèn) public
    plugins: [
        vue(),
        createHtmlPlugin(configMap[projectName])
    ],
    resolve:{
      alias:{
        '@':resolve(__dirname,'src')
      }
    },
    build: 
        {
            cssCodeSplit: true,
            emptyOutDir: true,
            sourcemap: false,
            assetsDir: 'assets', // 默認(rèn) assets
            outDir: `dist-${projectName}`, // 輸出到dist
            rollupOptions: {
                input: {
                },
                output: {
                    compact: true,
                    entryFileNames: "assets/js/[name]-[hash].js",
                    chunkFileNames: "assets/js/[name]-[hash].js",
                    assetFileNames: "assets/[ext]/[name].[ext]",
                }
            }
        },
        
})

package.json文件也需要重新修改scripts部分，主要實(shí)現(xiàn)npm run build打出多個(gè)dist包

package.json

  "scripts": {
    "dev": "vite",
    "build": "node dynamic-build-all.js",
    "preview": "vite preview"
  },

dynamic-build-all.js：

import { projects } from './projects.js';
import { execSync } from 'child_process';
const projectNames = Object.keys(projects);
for (const projectName of projectNames) {
  console.log(`Building ${projectName}...`);
  const command = projects[projectName].buildCommand;
  execSync(command, { stdio: 'inherit' });
}

projects.js存放項(xiàng)目配置

export const projects = {
    projectA: {
      name: "projectA",
      buildCommand: "cross-env PROJECT_NAME=projectA vite build",
      desc: "協(xié)議一"
    },
    projectB: {
      name: "projectB",
      buildCommand: "cross-env PROJECT_NAME=projectB vite build",
      desc: "協(xié)議二"
    }
}
