Socket connection re-implemented. Everything is working fine now. All thats left to do is to make the app robust and handle some edge cases. TODO - The friends list is maybe hardcoded or whatever I dont know, but the problem is it shows the same username no matter who the signed in user is. I need to fix that. - Whenever the pawn reaches to tha last square for promotion an 'Invalid move' error is thrown by the Chess class. Need to fix that too. - Need to disable the chessboard (so user cannot make any moves) until the opponent has joined the game. - Set timers for the game. - Need to show the loading states in various places in the app. - Improve the backend such that a user cannot create more than one room at a time. - Remove hardcoded values from various places. - Make the app responsive. The UI is good on desktop but it is very bad on mobile. - Add a feature to search and add friends. - Destroying the rooms when the match ends and set timers for auto destruction after a certain time. - Need some logic to save games in the history. - Add some tests.
