Connect to AWS MySQL database via Node JS

Question

I have an instance on AWS and MySQL database working on it. I was able to connect to the instance via workbench on my local machine. However, I am not able to connect to the database via the node js code. Below is the snippet :

var express    = require("express");
var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'ec2-52-33-41-xxx.us-west-2.compute.amazonaws.com',
 port      :  3306,
  user     : 'ec2-user',
  password : 'root',
  database : 'FAMILY_GIVING_TREE'

});
var app = express();

connection.connect(function(err){

if(!err) {
    console.log("Database is connected ... ");    
} else {
    console.log("Error connecting database ... ");    
}
});

THE ERROR is :

{ [Error: connect ECONNREFUSED 52.33.xx.84:3306]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect',
  address: '52.33.41.84',
  port: 3306,
  fatal: true }

The node js code is w=not written over the AWS instance, I am writing it on my machine and yes the port 3306 is enabled in security groups.

I get the database connection issue. Any idea where am I going wrong? Thanks in advance.

There is a syntax error in your node.js code. Replace port : 3306, with below you are missing the ''

port : '3306',
