Signal Backend Clone

Overview

This repository contains the backend code for a Signal web chat clone, implemented using Node.js, Express, Socket.IO and MongoDB. It provides RESTful API endpoints for user authentication, messaging, and other features required for the Signal clone application.

Features

• User Authentication: Implement user authentication functionalities, including sign up, log in, log out, and token-based authentication using JSON Web Tokens (JWT).

• Real-time Messaging: Enable real-time messaging functionality using Socket.IO, allowing users to send and receive messages instantly.

• Data Persistence: Connect to a MongoDB database to store user data, messages, and other relevant information, ensuring data integrity and persistence across server restarts.

• Validation and Error Handling: Utilize Express.js middleware for request validation and error handling, ensuring robustness and security in API interactions.

• Cross-Origin Resource Sharing (CORS): Enable CORS middleware to allow cross-origin requests from the frontend application, facilitating communication between the client and server.
