vue3 + vite 多项目多模块打包

本示例基于vite-plugin-html插件，实现多个独立项目共存，共享组件和依赖，运行、打包互不干扰。

npm create vite@latest

兼容性注意

Vite 需要 Node.js 14.18+ 、16+版本，有些模板需要更高的版本

虽然创建项目用的14.17.5版本，但是后面运行项目用的18.15.0

HTML模板插件

npm i vite-plugin-html -D #vite.config.ts import {defineConfig} from "vite" import vue from @vitejs/plugin-vue import {createHtmlPlugin} from vite-plugin-html const htmlParams = { minify: true, pages: [ { filename: index, // filename 默认是template文件名，就是index.html entry: /src/main.ts, template: index.html, } ] } export default defineConfig({ base: ./, // 方便打包后预览 publicDir: public, // 默认 public plugins: [vue(), createHtmlPlugin(htmlParams)], build: { cssCodeSplit: true, emptyOutDir: true, sourcemap: false, assetsDir: assets, // 默认 assets outDir: dist, // 默认 dist rollupOptions: { input: {}, // input 不用管，插件内会处理 output: { compact: true, entryFileNames: "static/js/[name]-[hash].js", chunkFileNames: "static/js/[name]-[hash].js", assetFileNames: "static/[ext]/[name].[ext]", } } } })

打包一下验证插件效果

npm run build

目录改造

beijing.html nanjing.html src - beijing - App.vue - main.ts - nanjing - App.vue - main.ts

新增文件(项目模板)：beijing.html 、nanjing.html

# beijing.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <link rel="icon" type="image/svg+xml" href="/static/imgs/vite.svg" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>北京项目</title> </head> <body> <div id="app"></div> <script type="module" src="/src/beijing/main.ts"></script> </body> </html>

nanjing.html内容略(把北京的复制一份)

新增目录及项目文件：beijing/App.vue 、beijing/main.ts 、nanjing/App.vue 、nanjing/main.ts

# beijing/main.ts import { createApp } from vue import ../style.css import App from ./App.vue createApp(App).mount(#app) # beijing/App.vue <script setup lang="ts"> import HelloWorld from ../components/HelloWorld.vue </script> <template> <div> <img src="/static/imgs/vite.svg" class="logo" alt="Vite logo"/> <img src="../assets/vue.svg" class="logo vue" alt="Vue logo"/> <h1>北京项目</h1> </div> <HelloWorld msg="HelloWorld"/> </template>

nanjing/App.vue 、nanjing/main.ts 内容略(把北京的复制一份)

注意文件路径，例如：vite.svg 、vue.svg 、style.css

#vite.config.ts import {defineConfig} from "vite" import vue from @vitejs/plugin-vue import {createHtmlPlugin} from vite-plugin-html const htmlParams = { minify: true, pages: [ { filename: beijing, // filename 默认是template文件名，就是beijing.html entry: /src/beijing/main.ts, template: beijing.html, }, { filename: nanjing, entry: /src/nanjing/main.ts, template: nanjing.html, }, ] } export default defineConfig({ base: ./, // 方便打包后预览 publicDir: public, // 默认 public plugins: [vue(), createHtmlPlugin(htmlParams)], build: { cssCodeSplit: true, emptyOutDir: true, sourcemap: false, assetsDir: assets, // 默认 assets outDir: dist, // 默认 dist rollupOptions: { input: {}, // input 不用管，插件内会处理 output: { compact: true, entryFileNames: "static/js/[name]-[hash].js", chunkFileNames: "static/js/[name]-[hash].js", assetFileNames: "static/[ext]/[name].[ext]", } } } })

打包结果

我这的java项目集成的是FreeMarker ，

把项目模板beijing.html改成beijing.ftl ，修改文件里对应的静态资源路径，

前端打包之后，把dist下面的文件同步到java项目的static目录。

别名配置

ts 配置，新增项 baseUrl、types 、paths

# tsconfig.json { "compilerOptions": { "target": "ESNext", "useDefineForClassFields": true, "module": "ESNext", "moduleResolution": "Node", "strict": true, "jsx": "preserve", "resolveJsonModule": true, "isolatedModules": true, "esModuleInterop": true, "lib": ["ESNext", "DOM"], "skipLibCheck": true, "noEmit": true, "baseUrl": "src", "types": ["vite/client"], "paths": {"@/*": ["./*"]} }, "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"], "references": [{ "path": "./tsconfig.node.json" }] }

vite 配置，新增项 resolve.alias

# vite.config.ts import {resolve} from "path"; import {defineConfig} from "vite" import vue from @vitejs/plugin-vue import {createHtmlPlugin} from vite-plugin-html const htmlParams = { minify: true, pages: [ { filename: beijing, // filename 默认是template文件名，就是beijing.html entry: /src/beijing/main.ts, template: beijing.html, }, { filename: nanjing, entry: /src/nanjing/main.ts, template: nanjing.html, }, ] } export default defineConfig({ base: ./, // 方便打包后预览 publicDir: public, // 默认 public plugins: [vue(), createHtmlPlugin(htmlParams)], resolve: { alias: { @: resolve(__dirname, src), } }, build: { cssCodeSplit: true, emptyOutDir: true, sourcemap: false, assetsDir: assets, // 默认 assets outDir: dist, // 默认 dist rollupOptions: { input: {}, // input 不用管，插件内会处理 output: { compact: true, entryFileNames: "static/js/[name]-[hash].js", chunkFileNames: "static/js/[name]-[hash].js", assetFileNames: "static/[ext]/[name].[ext]", } } } })

项目里面，引入文件："../assets/vue.svg" 、"../components/HelloWorld.vue" 改为 "@/assets/vue.svg"、"@/components/HelloWorld.vue"
