Project
High-Level Summary
Chesso is a full-stack, real-time multiplayer chess platform engineered to provide low-latency online gameplay. It features real-time move synchronization, authoritative backend match clocks, secure authentication using JWT and Google OAuth, and full chess rule validation. I built it using the MERN stack (MongoDB, Express, React, Node.js) combined with Socket.IO for bi-directional WebSocket communication and Chess.js for move validation and FEN (Forsyth–Edwards Notation) state management. One of the main challenges I solved was building a server-authoritative state and clock synchronization mechanism to prevent client tampering and handle mid-game reconnections gracefully.
Tech Stack & Architectural Overview
Frontend : React, Vite for fast builds, React for declarative UI updates upon WebSocket events.
