vue-cli 官方提供的一个脚手架（预先定义好的目录结构及基础代码，咱们在创建 Maven 项目时可以选择创建一个骨架项目，这个骨架项目就是脚手架）用于快速生成一个 vue 的项目模板
请自行前往 http://nodejs.cn/download 官网下载安装，此处不再赘述

安装并运行成功后在浏览器输入：http://localhost:8080
build 和 config：WebPack 配置文件node_modules：用于存放 npm install 安装的依赖文件src：项目源码目录static：静态资源文件.babelrc：Babel 配置文件，主要作用是将 ES6 转换为 ES5.editorconfig：编辑器配置eslintignore：需要忽略的语法检查配置文件.gitignore：git 忽略的配置文件.postcssrc.js：css 相关配置文件，其中内部的 module.exports 是 NodeJS 模块化语法index.html：首页，仅作为模板页，实际开发时不使用package.json：项目的配置文件
name：项目名称version：项目版本description：项目描述author：项目作者scripts：封装常用命令dependencies：生产环境依赖devDependencies：开发环境依赖│ App.vue│ main.js│├─assets│ logo.png│└─components HelloWorld.vue项目的入口文件，我们知道所有的程序都会有一个入口
1 // The Vue build version to load with the `import` command 2 // (runtime-only or standalone) has been set in webpack.base.conf with an alias. 3 import Vue from ‘vue‘ 4 import App from ‘./App‘ 5 Vue.config.productionTip = false 6 /* eslint-disable no-new */ 7 new Vue({ 8 el: ‘#app‘, 9 components: { App }, 10 template: ‘<App/>‘ 11 })
import Vue from ‘vue‘：ES6 写法，会被转换成 require("vue"); （require 是 NodeJS 提供的模块加载器）import App from ‘./App‘：意思同上，但是指定了查找路径，./ 为当前目录Vue.config.productionTip = false：关闭浏览器控制台关于环境的相关提示new Vue({...})：实例化 Vue
el: ‘#app‘：查找 index.html 中 id 为 app 的元素template: ‘<App/>‘：模板，会将 index.html 中 <div id="app"></div> 替换为 <App />components: { App }：引入组件，使用的是 import App from ‘./App‘ 定义的 App 组件组件模板
1 <template> 2 <div id="app"> 3 <img src="./assets/logo.png"> 4 <HelloWorld/> 5 </div> 6 </template> 7 <script> 8 import HelloWorld from ‘./components/HelloWorld‘ 9 export default { 10 name: ‘App‘, 11 components: { 12 HelloWorld 13 } 14 } 15 </script> 16 <style> 17 #app { 18 <!-- 字体 --> 19 font-family: ‘Avenir‘, Helvetica, Arial, sans-serif; 20 <!-- 文字平滑效果 --> 21 -webkit-font-smoothing: antialiased; 22 -moz-osx-font-smoothing: grayscale; 23 text-align: center; 24 color: #2c3e50; 25 margin-top: 60px; 26 } 27 </style>
template：HTML 代码模板，会替换 <App /> 中的内容import HelloWorld from ‘./components/HelloWorld‘：引入 HelloWorld 组件，用于替换 template 中的 <HelloWorld/>export default{...}：导出 NodeJS 对象，作用是可以通过 import 关键字导入
name: ‘App‘：定义组件的名称components: { HelloWorld }：定义子组件基本同上，不解释..
关于 <style scoped> 的说明：CSS 样式仅在当前组件有效，声明了样式的作用域
