vue3 + vite 项目可以使用纯Js开发吗？

答案：可以

创建项目：

按照链接参考或者按官方：

webstorm 创建vue3 vite 项目-CSDN博客

项目目录

tsconfig.json 配置允许js

allowJs指定是否编译js文件，在任意文件当中,如果我们模块使用js写的，那么我们需要

将allowJs设置为true,默认为false,主要是在引入一个额外js之后防止路径错误才使用


{
	"compilerOptions": {
    //是否对js进行编译
    "allowJs": true
  }
}

打开项目之后创建一个新vue视图

<template>
  <div class="about">
    <h1>This is an Login page</h1>
    <br/>
    <el-divider/>
    <h4>{{ msg }}</h4>
    <el-button @click="handleClick">这个是el按钮</el-button>
  </div>
</template>
<script setup>
const handleClick = () => {
  msg.value = msg.value + ',hello'
  alert('点了一下了55555~~~')
}
const msg = ref('hello')


</script>

<style>
@media (min-width: 1024px) {
  .about {
    min-height: 100vh;
    display: flex;
    align-items: center;
    flex-direction: column;
  }
}
</style>

/router/index.ts 添加到路由

import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue'

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/',
      name: 'home',
      component: HomeView
    },
    {
      path: '/about',
      name: 'about',
      // route level code-splitting
      // this generates a separate chunk (About.[hash].js) for this route
      // which is lazy-loaded when the route is visited.
      component: () => import('../views/AboutView.vue')
    },
    {
      path: '/login',
      name: 'login',
      component: () => import('../views/loginView.vue')
    }
  ]
})

export default router

App.vue里遍历路由展示所有的页面，包括上面的login.vue

<template>
  <header>
    <img alt="Vue logo" class="logo" src="@/assets/logo.svg" width="125" height="125" />

    <div class="wrapper">
      <HelloWorld msg="You did it!" />

      <nav>
        <RouterLink v-for="item of routes" :to="item" :key="item.name">{{ item.name }}</RouterLink>
      </nav>
    </div>
  </header>
  <!--RouterLink的跳转的页面内容将在RouterView显示-->
  <RouterView />
</template>
<script setup lang="ts">
import { RouterLink, RouterView } from 'vue-router'
import HelloWorld from './components/HelloWorld.vue'
import router from '@/router'

const routes = router.options.routes
// console.log(router.options.routes)
</script>

<style scoped>
header {
  line-height: 1.5;
  max-height: 100vh;
  background-color: #bfc;
}

.logo {
  /*display: block;*/
  display: none;
  margin: 0 auto 2rem 2rem;
}

nav {
  width: 100%;
  font-size: 12px;
  text-align: center;
  margin-top: 2rem;
}

nav a.router-link-exact-active {
  color: var(--color-text);
}

nav a.router-link-exact-active:hover {
  background-color: transparent;
}

nav a {
  display: inline-block;
  padding: 0 1rem;
  border-left: 1px solid var(--color-border);
}

nav a:first-of-type {
  border: 0;
}

@media (min-width: 1024px) {
  header {
    display: flex;
    place-items: center;
    padding-right: calc(var(--section-gap) / 2);
  }

  .logo {
    display: block;
    margin: 0 2rem 0 2rem;
  }

  header .wrapper {
    display: flex;
    place-items: flex-start;
    flex-wrap: wrap;
  }

  nav {
    text-align: left;
    margin-left: -1rem;
    font-size: 1rem;

    padding: 1rem 0;
    margin-top: 1rem;
  }
}
</style>
