???? Project Title:

Video Calling App (Node.js + WebRTC)

???? Summary:

The Video Calling App is a real-time communication platform built using Node.js for the backend and WebRTC for peer-to-peer video and audio communication. It enables users to initiate and receive video calls directly through their web browsers without the need for external plugins or software. This project provides secure, scalable, and interactive video calling capabilities.

✨ Key Features:

User Authentication: Secure login and registration for users.

Real-Time Video & Audio Calls: High-quality, low-latency video and voice calls.

Peer-to-Peer Connection: WebRTC technology ensures direct browser-to-browser communication.

Call Invitation System: Users can invite others via email or link for video calls.

Text Messaging During Calls: Send chat messages during a live video session.

Call Recording: Option to record video calls for future reference.

Screen Sharing: Share the screen for presentations or collaborative sessions.

Group Video Calls: Support for multiple users in a single video call.

Admin Panel: Monitor active calls, users, and manage settings.

Cross-Platform Support: Works across desktop and mobile browsers.

End-to-End Encryption: Secure communication with encryption for privacy.

????️ Technologies Used:

Frontend: HTML, CSS, JavaScript (React.js or Vanilla JS for UI)

Backend: Node.js with Express.js

Real-Time Communication: WebRTC (Web Real-Time Communication)

Database: MongoDB, Redis for real-time message storage

WebSocket: For real-time signaling (for call setup and maintenance).

Authentication: JWT Tokens for secure login and session management

Deployment: Docker, AWS, or Heroku for cloud hosting

Security: HTTPS, STUN/TURN servers for WebRTC connection reliability

⚙️ Working Process:

User Registration/Login: Users sign up or log in securely using JWT tokens.

Create a Call Room: Users create a call or meeting room and invite participants by sharing a link.

Peer-to-Peer Connection: WebRTC establishes a direct peer-to-peer connection for video/audio streaming.

Real-Time Communication: Users can video call, send messages, and share screens in real-time.

Call Management: Calls can be recorded, ended, or muted by participants.

Admin Control: Admins can manage users and monitor active calls.

Call Termination & Logout: Calls end with the option to log out or join another session.

✅ Benefits:

No Plugins Required: WebRTC allows direct browser-to-browser communication without extra plugins.

Real-Time Communication: Supports high-quality, real-time video and audio calls for better interaction.

Scalable: Easily scalable for personal use, businesses, or group conferences.

Security: End-to-end encryption ensures user privacy and secure communication.

Cross-Platform Compatibility: Works on any modern browser (Chrome, Firefox, Safari, etc.) across devices.

Cost-Effective: Utilizes WebRTC's open-source and cost-efficient technology for video calling.

Improved Collaboration: Features like screen sharing and group calls enhance collaborative work.

Customizable: Easily extendable with additional features like file sharing, real-time collaboration, etc.
