Socket.io path on server side (Node.js) and client side (Angular)

Question

I have socket.io working locally. http://localhost:3000 is URL for Node.js backend and http://localhost:4200 URL for frontend Angular.

But it does not work when I deploy the app.

Folder structure:

parent-folder-name

 -backend folder

 -frontend files

All files of Angular located directly in the parent folder.

URLs:

http://mydomainnameexample.com/parent-folder-name/backend http://mydomainnameexample.com/parent-folder-name/ (frontend)

Code:

Client: this.socket = io('http://mydomainnameexample.com/parent-folder-name/');

Server side:

const http = require('http').Server(app);
const io = require('socket.io')(http);
io.sockets.on('connection', function(socket) {
  console.log('A client is connected!');

  socket.on('index', () => {
    console.log('socketData: ');
    testController.index(socket);
  });
});

I do have 404 in the console for this URL: http://mydomainnameexample.com/parent-folder-name/backend/?EIO=3&transport=polling&t=MQnDIEb

on the server side (Node.js) I added the path:

const io = require('socket.io')(http, {path: 'parent-folder-name/backend/socket.io'})`

And Client side:

this.socket = io('http://mydomainnameexample.com', { path: 'parent-folder-name/backend/socket.io' });
