Vue3使用路由及配置vite.alias简化导入写法的过程详解

yarn add vue-router

import { createApp } from "vue";
import { createRouter, createWebHashHistory } from 'vue-router';
import App from "./App.vue";
const Home = { render(){ return 'Home'} }
const Project = { render(){ return 'Project'} }
const routes = [
    { path: '/', component: Home },
    { path: '/project', component: Project },
  ]
const app = createApp(App);
const router = createRouter({
  // 4. 内部提供了 history 模式的实现。为了简单起见，我们在这里使用 hash 模式。
  history: createWebHashHistory(),
  routes, // `routes: routes` 的缩写
});
app.use(router);
app.mount("#app");

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

yarn add @types/node

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'),
    }
  }
})

 "baseUrl": "./",
    "paths": {
      "@/*": ["./src/*"]     //格式一定要写对符号*不能少不然找不到@或者没有代码提示
    },
