OnlineChessBack

Node.js server that uses Express and Socket.io libraries to create a real-time multiplayer game server. Connects players and redirects moves made in the frontend. Frontend repository can be found here.

The server uses Express to handle HTTP requests, and Socket.io to handle real-time communication between clients and the server.
