About The Project

GoChat is a real-time chat application that allows users to send and receive messages instantly. It utilizes Go for the backend, WebSockets for real-time communication, and Redis for message persistence and pub/sub functionality. The frontend is built with HTML, CSS (Tailwind CSS), and JavaScript.

Key Features
