<template>
  <div id="app">
    <transition :name="transitionName">
      <navigation>
        <router-view class="router" />
      </navigation>
    </transition>
    <van-tabbar route>
      <van-tabbar-item replace to="/home" icon="home-o">
        Home
      </van-tabbar-item>
      <van-tabbar-item replace to="/about" icon="search">
        About
      </van-tabbar-item>
    </van-tabbar>
  </div>
</template>
