The app includes dedicated pages for user authentication, allowing users to log in or sign up to access the chat functionality.

This widget includes two main actions: a signout button and an online status icon, which represents the socket server's status.

A user list page displays all users along with their online status. Users can easily identify who is online and initiate chats.

The chat page provides a user-friendly interface for users to engage in real-time conversations. The chat history between two users is displayed, and new messages are instantly updated.

Users can send and receive messages in real-time, providing a smooth and interactive chat experience.

Secure user authentication is implemented using JSON Web Tokens (JWT), ensuring a safe and personalized messaging experience.

Messages and user data are stored in a MongoDB database. MongoDB Compass, a graphical user interface, can be used for easy database management. Additionally, MongoDB Atlas, a cloud-based database service, offers a scalable and reliable solution for data storage.

Real-time communication is achieved through Socket.io, enabling instant message updates and notifications.

Passwords are securely hashed using bcrypt to enhance user authentication.

Cross-Origin Resource Sharing (CORS) is handled using the cors package to enable secure communication with the frontend.

The dotenv package is used to load environment variables from a .env file.

The server framework used for handling HTTP requests and routes.

Input validation is performed using the express-validator package.

JSON Web Tokens (JWT) are used for secure user authentication.
