socket io changes socket.id repeatedly

Question

Is this normal behavior? socket.io-1.3.2.js From the client:

socket = io.connect('https://socket.myserver.nl');
    socket.on('connect', function() {
    socket.emit('register', userID, 'Lobby');//ignore this
    });

At the server Node version v5.2.0:

 io.sockets.on('connection', function (socket) {
    console.log('SOCKET CONNECTING '+socket.id); 
  ////lots of other code//////////


  socket.on('disconnect', function() {  
    console.log('SOCKET DISCONNECTING '+socket.id);    
  });
  });

During test when i make a single connection with a client to the server and further doing absolutely nothing i get the following (5 minutes approximately):

SOCKET CONNECTING SddHIXmWSeHEfDnlAAAC

SOCKET DISCONNECTING SddHIXmWSeHEfDnlAAAC

Answer 1

If you use React, Vue or something like that

Create another js file inside src and type these lines for connecting socket.Export socket.id and socket. Because you need to run socket.io out of dynamic rendered components.

import { io } from 'socket.io-client';

export const socket = io('http://localhost:5000');
export let socketID = '';
socket.on('connect', () => {
    socketID = socket.id
})

And inside React components you can import them.

import { socketID, socket } from './socket';
