How to Socket.io Specifying Heartbeat

Here we Learn Method of Set Ping Timeout & ping interval.
There Are Several Way to Set Ping interval & Ping Time out.

Please Remember Some note : ping interval is alway small then ping Timeout.
Always Set Same ping timeout & ping Interval for both side. (Client side  & Server Side) When You Develop any Client Server Application.

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http, {
'pingInterval': 2000,
'pingTimeout': 5000
});

For package dependency versions:

"express": "^4.12.3",

ex :

var app = express();
var server = require('http').createServer(app);
var io = require('socket.io')(server);

io.set('heartbeat timeout', 5000);
io.set('heartbeat interval', 2000);
