还差两个

1、app下面栏怎么弄得

app.vue

<template>
  <div id="app">
    <router-view />
      <div style="    position:fixed;bottom:0;100%;">
        <van-row class="user-links" >
          <van-col span="8">
            <router-link to='list'>
            首页
            </router-link>
          </van-col>
          <van-col span="8">
            <router-link to='add'>
            发文
            </router-link>
          </van-col>
          <van-col span="8">
            <router-link v-if="!$store.state.logined" to='login'>
              未登陆
            </router-link>
            <router-link v-if="$store.state.logined" to='user'>
              用户
            </router-link>
          </van-col>
        </van-row>
        </div>
  </div>
</template>
<script>

</script>
<style>
body {
  font-size: 16px;
  background-color: #f8f8f8;
  -webkit-font-smoothing: antialiased;
}
</style>

2、Cannot find module './model/mysqlApi'

let mysql = require('mysql');
let db_config={
     //Options
    host:'10.**',
    port:'**',
    user:'**',
    password:'**',
    database:'test'
}

const pool = mysql.createPool(db_config)
let query = function( sql, values ) { 
    return new Promise(( resolve, reject )=> { 
         pool.getConnection(function(err, connection) { 
            if(err) { 
                reject( err )
            }
            else {
                connection.query(sql, values, ( err, rows) => { 
                    if ( err ) {
                        reject( err ) 
                    }
                    else {
                        resolve( rows ) 
                    } 
                    connection.release() 
                }) 
            } 
        }) 
    }) 
} 

exports.query = query
