Full-stack project: SYNK ChatApp, a real-time chat application built entirely with the MERN stack (MongoDB, Express.js, React.js, and Node.js).
This project deep dive into building a secure, responsive, and modern web application from scratch. It handles everything from user authentication to live, instantaneous messaging.

🔑 Key Features
I designed this application to be feature-rich and intuitive. Here’s what it can do:

🔒 User Authentication & Security
Secure Sign-up: New user registration with robust password hashing using bcrypt.
User Login: Secure authentication using JSON Web Tokens (JWT), providing stateless auth for all API requests.
Persistent Login: Users remain logged in across browser sessions for a seamless experience.
Logout: Securely invalidate the user's session.
💬 Live Messaging
Instant Communication: Real-time, 1-to-1 message delivery and reception using Socket.IO.

🎨 User Interface & Experience
Responsive Design: A clean, mobile-first UI built with React.js, Tailwind CSS, and Material-UI that looks great on all screen sizes.
Contact List: View all registered users and easily start new conversations.
Chat History: All messages are saved to the database and loaded when a conversation is opened.
Profile Avatars: Users can set and update their profile pictures.

🛠️ Tech Stack
This project utilizes the MERN stack and other modern web technologies:

🖥️ Backend
Node.js & Express.js: For the core server-side logic and RESTful API.
MongoDB: As the NoSQL database for storing user and message data.
Socket.IO: The library enabling real-time, bidirectional event-based communication.
JWT (jsonwebtoken): For generating and verifying authentication tokens.
bcrypt.js: For hashing user passwords before saving them to the database.

📱 Frontend
React.js: The JavaScript library for building the user interface.
React Router: For client-side routing and navigation.
Zustand: For lightweight and flexible state management.
Tailwind CSS & Material-UI: For styling the application with a modern look and feel.
