从零开始搭建企业级前端项目模板（vue3+vite+ts）

blog.csdn.net/jastalented…

针对 Vue3 + TypeScript + Vite 项目中遇到的“找不到模块“./App.vue”或其相应的类型声明”的问题，即使路径正确但仍然无法构建（npm run build），可以尝试以下解决方案：

第4，5步弄好之后我又去build，报了个

最后又安装了这个依赖 npm i terser，再去build终于成功了。。。

vue2 我使用的是这个

配置改了些：

vue3的可以用 vue3js.cn/

Vue3.0的新语法糖-script setup

export default service

//  当状态码是401时需要单独处理，跳回登录页

接口写法api

import request from '@/utils/request'
let token = localStorage.getItem('token')
export function getUnusedProduct(data) {
  return request({
    url: '/report/unusedProduct',
    method: 'post',
    data,
    headers: {
      'token': token
    }
  })
}

export function getUnusedProductTotal(data) {
  return request({
    url: '/report/unusedProductTotal',
    method: 'post',
    data,
    headers: {
      'token': token
    }
  })
}

调用api
