About the Project
NestChat is a real-time messaging platform designed for speed. By utilizing Redis as a message broker and Socket.io for persistent connections, the app handles message delivery with sub-millisecond latency. The project focuses on horizontal scalability, ensuring that even as user traffic increases, the Pub/Sub architecture keeps chat rooms synchronized across multiple server instances. Authentication is handled via NextAuth with Google integration for a seamless onboarding experience.
