Chat App API

This project is a backend API for a chat application developed using TypeScript. It provides the necessary functionality for user registration, authentication, real-time messaging, and chat room management. The API is built with Express.js and utilizes WebSockets for real-time communication. JSON Web Tokens (JWT) are used for user authentication and authorization.
