how to get session id of socket.io client in Client

Question

I want to get session id of client in my socket.io client.

here is my socket.io client :

var socket = new io.Socket(config.host, {port: config.port,          


        

Answer 1

On socket.io >=1.0, after the connect event has triggered:

var socket = io('localhost');
var id = socket.io.engine.id

Answer 2

On Server side

io.on('connection', socket => {
    console.log(socket.id)
})

On Client side

import io from 'socket.io-client';

socket = io.connect('http://localhost:5000');
socket.on('connect', () => {
    console.log(socket.id, socket.io.engine.id, socket.json.id)
})

If socket.id, doesn't work, make sure you call it in on('connect') or after the connection.
