Real-Time Chat Application
This project is a real-time chat application that allows users to connect with others, send and receive messages instantly, and see the online status of other participants. It's built with React for the frontend and Node.js with Socket.io for real-time communication on the backend. Users can choose a username, send messages, and see system notifications when users join or leave the chat.

Note: Due to the free tier hosting on Render, the server may take a few moments to start up when accessing the live demo. Please be patient if there's a slight delay.

Challenges and Solutions
One significant challenge was ensuring smooth real-time communication between the frontend and backend, especially handling user connections and disconnections. This was solved by leveraging Socket.io's event-driven architecture to update the online users' list and broadcast system messages efficiently.
Future Improvements
- Add user authentication to secure chat sessions
- Implement private messaging between users
- Enhance UI for mobile responsiveness
- Include message encryption for secure communication
Reflection
This project helped me understand the power of real-time web applications and how to manage state effectively between users in different locations. I learned how to integrate frontend and backend seamlessly using Socket.io and the importance of deploying a stable, secure chat application.
