公司有个同事用Nuxt写了个项目，我一想，我还没有用Nuxt写过项目呢
刚把得，我也要会用nuxt写项目
看了一下同事项目的效果，他说是用的element-ui，然后是样式覆盖
ok了
本宝宝也要会这个
接下来看下github上面的项目
先放下作者大大的github地址：https://github.com/zhangliang1013/xian-yun
我们看下项目运行的效果

接下来我们看下代码
看了下package.json应该主要是用的nuxt.js和element-ui

//package.json
{
  "name": "xianyun",
  "version": "1.0.0",
  "description": "My supreme Nuxt.js project",
  "author": "liang_ge",
  "private": true,
  "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start",
    "generate": "nuxt generate"
  },
  "dependencies": {
    "@nuxtjs/axios": "^5.3.6",
    "element-ui": "^2.4.11",
    "less": "^3.10.3",
    "less-loader": "^5.0.0",
    "moment": "^2.24.0",
    "nuxt": "^2.0.0",
    "vuex-persistedstate": "^2.7.1"
  },
  "devDependencies": {}
}

看项目目录我还比较懵逼的，找不到入口文件，就结合界面UI来看
目测layout应该是入口

header和footer是共用的东西
先看footer,footer中的内容比较简单和固定

//footer.vue
<template>
    <div class="footer-wrapper">

            <el-row class="info-list">

header里面的效果我有想关注的，比如点击变色或者下面出现一条横线那种效果，然后对应页面渲染的

接下来我们仔细看看header中作者是怎么写的

不过这个作者写的，额，跟我想的不一样
header组件中无特殊处理,hover的时候下面出现一条横线那种

//header.vue
<template>
  <div class="header">
    <!-- logo部分 -->
    <el-row type="flex" class="row-bg" justify="space-between" align="middle">

        <nuxt-link to="/air">国内机票</nuxt-link>
      </el-row>
      <!-- 登录部分 -->
      <div class="login">

        <!-- 如果用户存在则展示用户信息，用户数据来自store -->

      this.$store.commit(‘user/getData‘,{

      if(this.$store.state.user.userInfo.token == ‘‘){

我们看下这个页面

哈哈，我以为会有什么特殊的处理，原来就是这一句话啊

说明我上面的推测是错的

这个是控制的样式
这个直接点击，其实是直接进入到了组件里面，不过比较奇怪的事情是居然不用在一个大的目录里面写router.js写好之类的
接下来看这个页面


接下来是这个页面

air页面里面的东西才比较多，我们可以看下代码
index页面里面的代码也一般
