使用vite创建vue3+ts项目完整流程

1.创建项目

npm init vite@latest

依次输入项目名称、选择vue、选择ts

2.引入依赖

cd 项目名称
npm install

3.启动项目

npm run dev

4.引入vue-router

npm install vue-router@4 -S

在src目录下新建router/index.ts并编写一下代码

import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router'

const routes: Array<RouteRecordRaw> = [
    {
        path: '/',
        component: () => import('../components/HelloWorld.vue')
    }
]

const router = createRouter({
// createWebHashHistory hash 路由
// createWebHistory history 路由
// createMemoryHistory 带缓存 history 路由
    history: createWebHistory(),
    routes
})

export default router

然后修改main.ts文件为：

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

继续修改App.vue文件为：

<script setup lang="ts"></script>

<template>
    <img alt="Vue logo" src="./assets/logo.png"/>
    <router-view/>
    <!--  <HelloWorld msg="Hello Vue 3 + TypeScript + Vite" />-->
</template>

<style>
#app {
    font-family: Avenir, Helvetica, Arial, sans-serif;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    text-align: center;
    color: #2c3e50;
    margin-top: 60px;
}
</style>

5.引入vuex

npm install vuex@next --S

src目录下新建store/index.ts并编写一下代码

import { createStore } from 'vuex'
const store = createStore({
    state: {
        userInfo: {
            name:'myName'
        }
    },
    mutations: {
        getUserInfo (state:any, name:string|number) {
            state.userInfo.name = name
        }
    },
    actions: {
        asyncGetUserInfo (context:any) {
            setTimeout(() => {
                context.commit("getUserInfo", +new Date() + 'action')
            },2000)
        }
    },
    getters: {
        userInfoGetter (state:any) {
            return state.userInfo.name
        }
    }
})

export default store;

继续修改main.ts文件：

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from "./store";
createApp(App).use(router).use(store).mount('#app')

ok 大功告成 接下来就可以愉快的编写代码啦
使用了vue3+typescript+vue-router+vuex
