Error: read ECONNRESET when connected to a mysql server with Node.js

I'm trying to establish a simple connection to my database with the mysql npm package. At first glance, everything works fine and I can get the information I need, however, if I leave the server running for some time I get the following error:
Error: read ECONNRESET at TCP.onStreamRead 

const express = require('express');
const app = express();`

const mysql = require('mysql');

 const db = mysql.createConnection({
  host: 'XXXX.mysql.database.azure.com',
  user: 'XXXXX',
 password: 'XXXXX',
 database: 'XXXXX'

})
    db.connect((err)=>{
    if(err){
       console.log(err.message);
    } else {
        console.log('Connected to the database');
    }
})

As far as I understand the problem stems from the database connection being in idle mode. Do I need to configure the Azure server or is there something else I need to do?

Couple of things to try:

  • You can try creating connection pool instead of **createConnection**

    mysql.createPool({});

  • Modify your package.json like below:

    "dependencies": {
        "mysql": "git://github.com/mysqljs/mysql#e3e123e9af7c0829a6c1417d911572a75b4a5f95"
      },

It is described in detail here:

Hope it helps.
