searchClientById was scanning through all open sockets to find the right one (which is inefficient if we have many). Instead, I created a new Map that directly maps ids to sockets. Furthermore, this solves a long-standing issue (when a socket is disconnected, we cannot find it anymore in the sockets list but it is still available in the disconnect callback from the map) As a result, we should not have any remaining circles any more.

}
All data users are stocked on socket client.

The information sent:
Socket.io => 'user-position'

x: position x on map
y: position y on map
}
All data users are updated on socket client.

The application sends position of all users in each room in every few 10 milliseconds.
The data will pushed on event user-position:
