vue3+ts+vite项目从0 搭建，配置安装router/pinia/element-plus/scss等

一、安装vite环境

官网：https://cn.vitejs.dev/guide/why.html

npm init vite

1.选择vue

2.选择typescipt

3.创建成功

默认项目结构如下

4.安装项目依赖

npm install 

5.启动项目

npm run dev

二。安装配置scss

1.运行安装scss

npm install -D sass sass-loader@^10 style-loader css-loader

2.配置vite.config.ts

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') // 根据你的项目结构进行修改'@': '/src',}},css: {preprocessorOptions: {scss: {additionalData: `@import "@/styles/variables.scss";` // 根据你的样式文件路径进行修改}}}
})

三、安装配置vue-router

npm install vue-router@next

1.新建router.ts文件

import { createRouter, createWebHistory } from 'vue-router'
import Home from '@/views/home/Index.vue'
import NotFound from '@/views/NotFound/Index.vue'
const routes = [{path: '/',name: 'Home',component: Home},{path: '/:pathMatch(.*)*',component: NotFound}
]const router = createRouter({history: createWebHistory(),routes
})export default router

2.修改main.ts

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'const app = createApp(App)
app.use(router)
app.mount('#app')

3.注意：：在src同级目录下新建shims-vue.d.ts，否则引入vue组件会报错：找不到模块“@/views/home/Index.vue”或其相应的类型声明

declare module '*.vue' {import { DefineComponent } from 'vue'const component: DefineComponent<{}, {}, any>export default component}

4.app.vue增加router-vire路由出口

目录结构如下：

四。安装pinia状态管理,，模块化

npm install pinia --save

1。main.ts 引入

2.创建store文件夹目录结构

3. index.ts文件引入stores/user

import {useUserStore }from "./stores/user";export default function useStore() {return {user: useUserStore(),};
}

3.stores/user.ts文件

import { ref } from 'vue'
import { defineStore } from "pinia";
import type { UserType } from '../types/user.d'export const useUserStore = defineStore("user", () => {let userList = ref<UserType[]>([])const getUserList = () => {userList.value = [{ username: "测试" }];}return {userList,getUserList}})

4.type/user.d.ts文件定义ts类型接口

export interface UserType {username:string
}

5.vue文件中使用 home/index.vue

<script setup lang="ts">
// 导出指定模块
import useStore from '@/store'
const { user } = useStore()
// 获取
user.getUserList()
</script><template><div><ul><li v-for="item in user.userList" :key="item.username">姓名：{{ item.username }}</li></ul></div>
</template><style lang="scss" scoped></style>

运行结果

五。安装element-plus

npm  install element-plus

1.main.ts引入

import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'app.use(ElementPlus)

2.页面使用 button

效果图：
