使用Vite搭建vue3+TS项目的实现步骤

npm init vite@latest

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'

export default defineConfig({
  plugins: [vue()],
  //解决“vite use `--host` to expose”
  base: './',	//不加打包后白屏
  server: {             
    host: 'localhost',	
     port: 9527,      
    open: true
  },
  resolve:{   
    //别名配置，引用src路径下的东西可以通过@如：import Layout from '@/layout/index.vue'
    alias:[   
      {
        find:'@',
        replacement:resolve(__dirname,'src') 
      }
    ]
  }
})

npm install @types/node --save-dev

  "compilerOptions": {
    "target": "esnext",
    "useDefineForClassFields": true,

}

npm install --save-dev eslint eslint-plugin-vue

module.exports = {

	parserOptions: {
		sourceType: 'module'
	},
	parser: 'vue-eslint-parser',
	extends: ['plugin:vue/vue3-essential', 'plugin:vue/vue3-strongly-recommended', 'plugin:vue/vue3-recommended'],

npm install vue-router@4

import { createRouter, createWEBHistory, RouteRecordRaw } from 'vue-router'
import Layout from '../components/HelloWorld.vue'

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

const router = createRouter({
  history: createWebHistory(),
  routes
})

export default router

import { createApp } from 'vue'
import './style.CSS'
import App from './App.vue'
import router from './router'

createApp(App).use(router).mount('#app')

<script setup lang="ts">
</script>
<template>
  <router-view></router-view>
</template>

<style>

</style>

npm install axios 

// 首先先引入aixos
import axios from 'axios'
// 创建一个axios 实例
const service = axios.create({
    baseURL: "/api", // 基准地址
    timeout: 5000 // 超时时间
})
 
// 添加请求拦截器
service .interceptors.request.use(function (config) {
    // 在发送请求之前做些什么
    return config;
}, function (error) {
    // 对请求错误做些什么
    return Promise.reject(error);
});
 
// 添加响应拦截器
service .interceptors.response.use(function (response) {
    // 对响应数据做点什么
    return response;
}, function (error) {
    // 对响应错误做点什么
    return Promise.reject(error);
});
 
// 最后导出
export default service 

import service from "@/utils/request"

//写对应的接口
export let getList=(params)=>{
	return service({
		url:"/getlist",
		method:"get",
		params
	})
}

//然后在对应的页面引入使用即可。

server: {
    proxy: {
      '/api': {
        target: 'https://baidu.com',
        changeOrigin: true,
        rewrite: (path) => path.replace(/^\/api/, '')
      }
    }
 },
