🎥📞 WebRTC Video & Audio Chat App

🌟 Overview

This application uses WebRTC to enable real-time video and audio calls between two peers. Users can create a room with a unique code and password, then share the room details or link with a friend to initiate secure peer-to-peer video and audio calls. The backend is powered by a Node.js server utilizing Socket.IO, and the frontend is a React-based client.

🚀 Features

• 🔍 Peer-to-Peer Video and Audio Calls: Empower users to have direct video and audio interactions with each other using WebRTC, offering a seamless communication experience.

• 🛠 Room Creation and Management: Users can effortlessly create and manage rooms with unique codes and passwords. Room information is stored in MongoDB, allowing for scalability and persistence.

• 🔒 Secure Access: Ensure that only users with the correct room code and password can join a room, providing a private and secure environment for communication.

• ⚡ Real-Time Signaling with Socket.IO: Use Socket.IO for efficient real-time signaling between peers, ensuring smooth and reliable WebRTC connections.

• 🌐 Modern User Interface: The React front-end provides a responsive and intuitive user interface for an enhanced user experience.

• 🌍 Efficient NAT Traversal: Utilize Google’s STUN server to gather ICE candidates, facilitating the connection between peers through Network Address Translation (NAT) and firewalls.
