1.安装

yarn add vue-router@4

2. 配置相关

① 配置别名

vite.config.ts

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import * as path from 'path';
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias: [
      {
        find: '@',
        replacement: path.resolve('./src')
      }
    ]
  },
  base:'./',  //设置打包路径
  // server: {
  //     host: "localhost",
  //     port: 3000,
  //     https: true
  // },
})

如果是刚创建的typeScript项目,会出现报错提示"找不到模块path或相应的类型声明",所以需要安装@types/[node]

yarn add @types/node

typeScrip 配置别名后 stsconfig.json 需要添加 baseUrl path 配置 不然使用别名@会提示找不到

{
  "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": ".",
    "paths": {
      "@/*": ["src/*"]
    }
  },
  "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"],
  "references": [{ "path": "./tsconfig.node.json" }]
}

3. 路由配置文件

// 在src目录下添加router/index.ts文件，并配置

import { createRouter, createWebHashHistory } from "vue-router";
import Home from '../views/Home.vue'
const router = createRouter({
  history: createWebHashHistory(),
  routes: [{
    path: '/',
    name: 'home',
    component: Home,
  },
  {
    path: '/about',
    name: 'About',
    //路由懒加载
    component: () => import('../views/About.vue')
  }
  ]
})
export default router

4.mian.ts

import { createApp } from 'vue'
import './style.css'
import App from './App.vue'

import router from '@/router/index'
createApp(App).use(router).mount('#app')

5.App.vue

<template>
  <router-view></router-view>
</template>
