一、 初始化构建项目
npm create vite myProject -- --template vue-ts注：Vite 需要 Node.js 版本 14.18+，16+。然而，有些模板需要依赖更高的 Node 版本才能正常运行，当你的包管理器发出警告时，请注意升级你的 Node 版本。
二、创建服务器
使用 Koa2
1. 安装koa
npm i koa --save && npm i @types/koa --save-dev2. 安装中间件（koa-connect）
npm i koa-connect --save3. 安装koa处理跨域（koa2-cors）
npm i koa2-cors --save4. 安装中间件（koa-bodyparser）
利用koa-bodyparser来处理POST请求参数
npm i koa-bodyparser --savePOST请求参数的处理有2种方式：
- 利用
node.js原生的querystring.parse()方式拿到前端传过来的数据。 - 利用第三方中间件
koa-bodyparser
注：
- 本模块不支持解析multipart表单格式数据，请使用co-busboy解析multipart表单格式数据。
- middleware的顺序很重要，这个koa-bodyparser必须在router之前被注册到app对象上
5. 注册中间件
- 新增bin/app.js文件
const Koa = require('koa');const cors = require('koa2-cors')const bodyParser = require('koa-bodyparser')(async () => {const app = new Koa();app.use(cors())app.use(bodyParser())app.use(async (ctx, next) => {console.log(ctx)ctx.body = `<!DOCTYPE html><html lang="en"><head><title>koa2 + vite + ts + vue3 + vue-router</title></head><body><h1 style="text-align: center;">Hello</h1></body></html>`;});// parse request body:app.listen(9000, () => {console.log('server is listening in 9000');});
})();6. node进行启动服务
node bin/app.js三、安装模板引擎
npm i nunjucks --savenunjucks文档：Nunjucks 中文文档
廖雪峰nunjucks文档：使用Nunjucks - 廖雪峰的官方网站
- 创建config/templates.js
const nunjucks = require('nunjucks');function createEnv(path, opts) {var autoescape = opts.autoescape === undefined ? true : opts.autoescape,noCache = opts.noCache || false,watch = opts.watch || false,throwOnUndefined = opts.throwOnUndefined || false,env = new nunjucks.Environment(new nunjucks.FileSystemLoader(path, {noCache: noCache,watch: watch,}),{autoescape: autoescape,throwOnUndefined: throwOnUndefined,});if (opts.filters) {for (var f in opts.filters) {env.addFilter(f, opts.filters[f]);}}return env;
}function templates(path, opts) {var env = createEnv(path, opts);return async (ctx, next) => {ctx.render = function (view, model) {ctx.response.body = env.render(view, Object.assign({}, ctx.state || {}, model || {}));ctx.response.type = "text/html";};await next();};
}module.exports = templates;
- bin/app.js
// nunjucks 模板渲染
const templates = require('../config/templates')// add nunjucks as ./:
app.use(templates('./', {noCache: !isProduction,watch: !isProduction})
)四、路由配置
1. 安装 koa-router
npm i koa-router --save2. 创建config/controller.js
const router = require('koa-router')()
router.staticFiles = {}// add url-route in /controllers:function interception(str) {return str.substring(0, str.lastIndexOf('/'))
}
function addMapping(mapping) {for (const url in mapping) {if (url.startsWith('GET ')) {const path = url.substring(4)const funStr = mapping[url].toString()if (funStr.indexOf('ctx.render') > 0) {const str1 = funStr.match(/ctx.render[\s]*\([\s]*'(\S*)', \{/g)[0]const str2 = str1.replace(/ctx.render[\s]*\([\s]*'/g, '')const str3 = str2.replace(/'[\s]*,[\s]*\{/g, '')const strUrl = url.replace('GET ', '')if (strUrl != '/') {router.staticFiles[interception(strUrl)] = interception(str3)}}router.get(path, mapping[url])console.log(`register URL mapping: GET ${path}`);} else if (url.startsWith('POST ')) {const path = url.substring(5)router.post(path, mapping[url])console.log(`register URL mapping: POST ${path}`)} else if (url.startsWith('PUT ')) {const path = url.substring(4)router.put(path, mapping[url])console.log(`register URL mapping: PUT ${path}`)} else if (url.startsWith('DELETE ')) {const path = url.substring(7)router.del(path, mapping[url])console.log(`register URL mapping: DELETE ${path}`)} else {console.log(`invalid URL: ${url}`)}}
}function addControllers(filePath) {const fs = require('fs')fs.readdirSync(filePath).filter(f => {if (fs.statSync(filePath + '/' + f).isFile()) {if (f.endsWith('.js')) {const mapping = require(filePath + '/' + f)()addMapping(mapping)}}if (fs.statSync(filePath + '/' + f).isDirectory()) {addControllers(filePath + '/' + f)}})
}module.exports = function (dir, app) {// 读取/routes目录的路由配置const controllers_dir = dir || '../routes'addControllers(__dirname + '/' + controllers_dir)return router.routes()
}
3. routes/admin/index.js配置
module.exports = function () {return {'GET /': async (ctx, next) => {const pageInfo = {title: '页面标题'}ctx.render('src/mobile/official/dist/index.html', {pageInfo})}}
}五、集成 vue-router
1. 安装vue-router
npm i vue-router --save2. 新增项目模块(test)
- src/test/index.html（页面）
<!DOCTYPE html>
<html lang="en"><head><meta charset="UTF-8" /><meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no, width=device-width" /><meta name="format-detection" content="telephone=no" /></head><body><div id="app"></div><script type="module" src="./main.ts"></script></body>
</html>- src/test/views/index.vue （子页面）
<template><h1>内容</h1>
</template><script setup lang="ts">
import { inject } from 'vue'
const title = 'test'
</script>
- test/router/index.ts （路由配置）
import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router'const routes: RouteRecordRaw[] = [{path: '/',redirect: to => {return '/index'}},{path: '/index',name: 'Index',component: () => import('../views/index.vue')}
]const router = createRouter({history: createWebHistory(),routes
})export default router
- test/main.ts（main.js）
import { createApp } from 'vue'
import App from './App.vue'
import router from './router/index'
import { createPinia } from 'pinia'const app = createApp(App)
app.use(createPinia)
app.use(router)
app.mount('#app')
六、Vite配置(vite.config.ts)
Vite 会自动解析根目录下名为vite.config.ts的文件
配置 Vite | Vite 官方中文文档
1. 基本配置（vite.config.ts）
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'
import { existsSync } from 'fs'// 获取模块路径
const modulePath = process.env.npm_config_path.endsWith('/')? process.env.npm_config_path.slice(0, -1): process.env.npm_config_pathconst projectDirname = resolve(__dirname, './' + modulePath)let publicPath = '//res.test.com'if (!modulePath || !existsSync(projectDirname)) {// 路径不存在，停止运行console.log('\x1b[40m \x1b[31m 模块路径错误，请检查路径 \x1b[0m')process.exit(0)
}export default defineConfig(({ mode }) => {const alias: Record<string, string> = {'@': resolve(__dirname, 'src'),'@admin': resolve(__dirname, 'src/admin'),'@mobile': resolve(__dirname, 'src/mobile'),'@pc': resolve(__dirname, 'src/pc')}// 路径存在，配置入口/出口路径const moduleName = modulePath.split('/').reverse()[0]const project_pages = {}project_pages[moduleName] = resolve(__dirname, modulePath + '/index.html')return {// https://cn.vitejs.dev/guide/#index-html-and-project-rootroot: modulePath, // 项目根目录base: mode === 'production' ? publicPath + modulePath.replace(/^(.\/)?src+/, '') + '/' : '/',plugins: [vue()],resolve: {extensions: ['.js', '.ts', '.vue', '.json'],alias},server: {port: 8081,open: false,proxy: {}},build: {rollupOptions: {input: project_pages,output: {dir: resolve(__dirname, modulePath + '/dist'),chunkFileNames: 'static/js/[name]-[hash].js',entryFileNames: 'static/js/[name]-[hash].js',assetFileNames: 'static/[ext]/[name]-[hash].[ext]'}},minify: 'terser',terserOptions: {compress: {drop_console: true,drop_debugger: true}}}}
})
1. element-plus 按需引入
首先你需要安装 unplugin-vue-components 和 unplugin-auto-import这两款插件
npm install -D unplugin-vue-components unplugin-auto-importvite.config.ts
import AutoImport from 'unplugin-auto-import/vite'
import viteCompression from 'vite-plugin-compression'export default defineConfig(({ mode }) => {return {plugins: [vue(),AutoImport({imports: ['vue', 'vue-router'], // 自动导入vue和vue-router相关函数eslintrc: {enabled: false, // 默认false, true启用。生成一次就可以，避免每次工程启动都生成filepath: './.eslintrc-auto-import.json', // 生成json文件globalsPropValue: true}}),// gzip压缩 生产环境生成 .gz 文件viteCompression({verbose: true,disable: false,threshold: 10240,algorithm: 'gzip',ext: '.gz'})]}
})
2. Vant按需引入
npm i vite-plugin-style-import -Dvite.config.ts
注：2.0版本需要使用的是createStyleImportPlugin不要使用styleImprot了
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'
import { existsSync } from 'fs'//2.0之后版本用createStyleImportPlugin
import { createStyleImportPlugin, VantResolve } from 'vite-plugin-style-import';export default defineConfig(({ mode }) => {const alias: Record<string, string> = {'@': resolve(__dirname, 'src'),'@admin': resolve(__dirname, 'src/admin'),'@mobile': resolve(__dirname, 'src/mobile'),'@pc': resolve(__dirname, 'src/pc')}// 路径存在，配置入口/出口路径const moduleName = modulePath.split('/').reverse()[0]const project_pages = {}project_pages[moduleName] = resolve(__dirname, modulePath + '/index.html')return {root: modulePath,base: mode === 'production' ? '//res.test.com' + modulePath.replace(/^(.\/)?src+/, '') + '/' : '/',plugins: [vue(),createStyleImportPlugin({resolves: [VantResolve()],libs: [{libraryName: 'vant',esModule: true,resolveStyle: name => `../es/${name}/style`}]})],resolve: {extensions: ['.js', '.ts', '.vue', '.json'],alias},server: {port: 8081,open: false,proxy: {}},build: {rollupOptions: {input: project_pages,output: {dir: resolve(__dirname, modulePath + '/dist'),chunkFileNames: 'static/js/[name]-[hash].js',entryFileNames: 'static/js/[name]-[hash].js',assetFileNames: 'static/[ext]/[name]-[hash].[ext]'}},minify: 'terser',terserOptions: {compress: {drop_console: true,drop_debugger: true}}}}
})
如出现 Error: Cannot find module ‘consola‘
则需要安装consola（由于改依赖包有使用到consola）
npm i consola -D七、本地启动服务、打包项目的命令设置
