A simple real-time multiplayer chess app built with React, Node.js, and Socket.IO. This project supports real-time communication between two players in the same match — no backend database, no lobby, just pure chess.

Two players can play in real-time with synchronized moves and resign detection.

• Real-time multiplayer with Socket.IO

• Simple username + game code join system

• Turn-based logic and board sync

• Game over on resignation

• Fully responsive interface

Note: Requires Node.js version 18. You can use nvm to manage multiple Node versions.

1. Start the Server

cd chess-serverSide
npm install
npm audit fix --force
npm start

The server will run on port 5000.

2. Start the Client

Open a second terminal and run:

cd chess-clientSide
npm install --force
npm audit fix --force
npm start

The client will be available at http://localhost:3000.

To simulate both players, open two browser tabs with the same address.

• Frontend: React, Chess.js, Socket.IO Client
