学习vuejs之后，总得自己上手写一些完整的应用，才能够更加了解各个结构与组件之间的运用。
下面从最基础的准备工作开始：
用vue-cli搭建vue应用：先确保自己已经安装Node环境。
（1）Windows 上安装 Node.js
你可以采用以下两种方式来安装。
1、Windows 安装包(.msi)
32 位安装包下载地址 : https://nodejs.org/dist/v4.4.3/node-v4.4.3-x86.msi
64 位安装包下载地址 : https://nodejs.org/dist/v4.4.3/node-v4.4.3-x64.msi
（2）github上安装网易音乐api
从github上安装网易音乐api：git clone https://github.com/Binaryify/NeteaseCloudMusicApi.git
进入 cd C:Usersgcmg12wymusicNeteaseCloudMusicApi npm install
安装成功：node app.js http://localhost:3000/
git命令：Git init git clone
.使用淘宝 NPM 镜像
大家都知道国内直接使用 npm 的官方镜像是非常慢的，这里推荐使用淘宝 NPM 镜像。
淘宝 NPM 镜像是一个完整 npmjs.org 镜像，你可以用此代替官方版本(只读)，同步频率目前为 10分钟 一次以保证尽量与官方服务同步。
你可以使用淘宝定制的 cnpm (gzip 压缩支持) 命令行工具代替默认的 npm:
$ npm install -g cnpm --registry=https://registry.npm.taobao.org
这样就可以使用 cnpm 命令来安装模块了：$ cnpm install [name]
# 最新稳定版
$ cnpm install vue
（3）# 全局安装 vue-cli
$ cnpm install --global vue-cli# 创建一个基于 webpack 模板的新项目
$ vue init webpack my-project# 这里需要进行一些配置，默认回车即
（4）安装相关的UI，和css插件，vue-lazyload加载图片
安装npm i element-ui -S
安装sass npm install node-sass --save-dev
npm install sass-loader --save-dev
使用vue-lazyload加载图片
页面中使用：
此处需先准备router，使用路由<router-link></router-link>
vue-cli默认会安装vue-router
配置router/index.js文件：**/
import Vue from 'vue'
import Router from 'vue-router'
import Helloworld from '@/components/HelloWorld'
import Recommend from '@/page/recommend'
import HotRecommend from '@/page/hotrecommend'
import Search from '@/page/search'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
component: Helloworld
},
{
path: '/recommend',
component: Recommend
},
{
path: '/Hotrecommend',
component: HotRecommend
},
{
path: '/search',
component: Search
}
]
})
网易云音乐布局：
此处组件设计应用与整个站点，是公共组件：topbar，nav--tab，banner-slider
/** tab.vue页面 **/ <template> <div class="header-tab"> <el-carousel :interval="5000" arrow="always"> <el-carousel-item v-for="(item,idx) in imgUrls" :key="idx"> <img :src="item.url"/> </el-carousel-item> </el-carousel> </div> </template> <script> export default{ data(){ return { imgUrls:[ {url:'http://p1.music.126.net/5UlKznX9kY7v_MWNchxJ4A==/109951164142076726.jpg'}, {url:'http://p1.music.126.net/ZEtgG_Jfi5PIS-JUqw81KQ==/109951164142194585.jpg'}, {url:'http://p1.music.126.net/_TlDGdim3FxX06iojkT12w==/109951164140640210.jpg'}, {url:'http://p1.music.126.net/7SJbPREZfv_Zkam_E9FsbA==/109951164142217360.jpg'} ] }; }, methods:{ } } </script> <style lang="scss" rel="style/scss"> .el-carousel__item:nth-child(2n) { background-color: #99a9bf; } .el-carousel__item:nth-child(2n+1) { background-color: #d3dce6; } img{width: 100%;} .el-carousel__container{height: 165px;} </style>

1.知识点：父组件向子组件传值：props
父组件定义值：
子组件接收父组件的值：
2.使用filters过滤器 此时容易犯错 filters和methods是平级关系
定义filter和watch时出现错误：
Method "watch，filter" has type "object" in the component definition. Did you reference the function correctly?
3.Vue错误
4.获取第三方API数据：vue-axios
1.安装axios，vue-axios
main.js引入：
页面中this.axios.get('url')
渲染到页面：<li class="item" v-for="item in list>{{item.name}}</li>
依照以上步骤：首页获取第三方数据，并完美展示到页面上已经初步完成。
