1 安装yarn并创建vue3项目

npm install -g yarn

创建vite项目

yarn create vite

运行项目

 cd vite-project
 yarn
 yarn dev
# 注：已有项目使用 yarn install安装依赖包

打开vite.config.js文件配置一下路径别名 @

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from 'path'
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias: {
      "@": path.resolve(__dirname, "src"),
    },
  },
})

打开tsconfig.json文件

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

2 安装 pinia

使用yarn安装pina

 yarn add pinia

在src里面创建一个store文件夹在创建一个index.ts文件

import { defineStore } from 'pinia'
export const useStore = defineStore('main', {
  state: () => ({
    name: '你好陌生人！'
  })
})

在main.ts里面添加pinia实例注意要放在mount("#app")前面

import { createApp } from 'vue'
import './style.css'
import App from './App.vue'
import {createPinia} from 'pinia' #导入pinia
const pinia=createPinia();#创建pinia，并在vue实例中use(pinia)
createApp(App).use(pinia).mount('#app')

在src里面创建一个views文件夹在创建一个home.vue文件

<template>
    <h1>{{ stores.name }} 你好， vite + vue3 + TS + vue-router + pinia</h1>
</template>
<script setup lang="ts">
import { useStore } from "@/store/index"
const stores = useStore()
</script>

app.vue文件这里我们将默认的替换成home.vue

<script setup lang="ts">
import Home from '@/components/home.vue'
</script>
<template>
<Home msg="测试"/> 
</template>
<style scoped>
</style>

3 安装开始vue-router路由

yarn安装vue-router

yarn add vue-router@4

src里面创建一个router文件夹在创建一个index.ts文件

import { createRouter, createWebHistory } from "vue-router";
export const router = createRouter({
  history: createWebHistory(),
  routes: [
    {
      path: "/",
      name: "home",
      component: () => import("@/components/home.vue"),
    },
  ],
});

在main.ts里面添加router实例注意要放在mount("#app")前面

import { createApp } from 'vue'
import './style.css'
import App from './App.vue'
import {createPinia} from 'pinia'
import { router } from './router'# 导入router
const pinia=createPinia();
createApp(App).use(pinia).use(router).mount('#app')

修改app.vue文件，加入路由

<script setup lang="ts">
// import Home from '@/components/home.vue'
</script>
<template>
    <router-link to="/"></router-link>
    <router-view></router-view>
</template>
<style scoped>
</style>
