The solution is use pooling connection !

You can wrote code to handle connection manually, it works. However pooling is design for this, use pooling connection solved connection drop error.

var mysql = require('mysql');
var pool  = mysql.createPool({
    connectionLimit : 10,
     host            : 'example.org',
    user            : 'bob',
     password        : 'secret',
      database        : 'my_db'
    });

   pool.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
            if (error) throw error;
            console.log('The solution is: ', results[0].solution);
         });
