Issues with Socket.io Server Implementation

[BaibhavTiwari]

1. Socket Initialization CORS Configuration:

   • The CORS configuration is set to cors: true, which is insufficient for complex cross-origin setups. A more specific configuration is needed.

2. Broadcasting Events to All Clients (io.emit):

   • io.emit is used to broadcast events to all clients instead of targeting specific ones. This leads to unnecessary emissions.

3. Unnecessary and Unused Variables (RoomU1, RoomU2):

   • Variables like RoomU1 and RoomU2 are commented out and unused, cluttering the code.

4. Missing Disconnect Handling:

   • There is no handling for disconnect events, which could lead to resource leaks or improperly handled socket disconnections.

5. Inconsistent Room Management:

   • Room management is incomplete. Socket.io’s built-in room handling (socket.join() and socket.leave()) is not being used effectively.

6. Memory Leaks Due to Multiple Connections:

   • Without proper disconnect handling, multiple connections could lead to memory leaks or excessive socket instances.

7. No Error Handling for Invalid Data:

   • There is no error handling for invalid or missing data in events like Send_RoomJoin_Req, which could result in undefined behavior.

8. Event Key Naming Conflicts:

   • Object keys such as to and from in events like Send_Offer and Send_Ans may cause confusion and need better naming conventions.
