Tinode4Chat - Real-Time Chat Backend with Tinode and MongoDB

Overview

Tinode4Chat is a real-time chat backend that leverages the Tinode Instant Messaging Server for handling chat room messaging and MongoDB for storing user, chat room, and message data. The application allows users to create accounts, join chat rooms, send and receive real-time messages, and handle user presence.

The backend is built using Go, MongoDB as the primary database, and Tinode for WebSocket communication. The application is containerized using Docker and orchestrated with docker-compose.
