目录及文件作用简介

  • main.js

main.js 是我们的入口文件，主要作用是初始化vue实例，并使用我们需要的插件

  • App.vue

App.vue 是我们的根组件，所有页面都是在App.vue下面进行切换的， 可以理解为所有的组件都是App.vue的子组件，我 们可以把头部和底部及每个页面都出现的内容放在App.vue里面。

  • index.html

文件入口

  • build

文件夹中配置了 webpack 的基本配置、开发环境配置、生产环境配置等

  • config

文件夹中配置了路径端口值等

  • src

放置组件和入口文件

  • node_modules

为依赖的模块
