The Video Chat Module is a reusable, TypeScript-based video-chat solution designed to seamlessly integrate real-time video, audio, and chat features into modern web applications.
A Next.js Frontend with server-side rendering and dynamic routing, featuring customizable React components for video calls, chat widgets, and user presence indicators.
A Node.js Signaling Server powered by Socket.io for reliable WebRTC negotiation, handling SDP offers/answers, ICE candidate exchanges, TURN/STUN fallback, and real time chat message updates.
A Chat & Data Service Layer exposing RESTful endpoints and services for message persistence, history retrieval, and real-time presence updates.
A PWA Infrastructure using service workers, workbox, and manifest.json to provide a Progressive Web App experience with installable app capabilities.
A Utility & Integration Layer providing authentication strategies, network status hooks, notification handlers for real-time alerts and background notifications when users are not on the chat tab using FCM, and TURN/STUN server configuration for extensibility.
How it works
The Video Chat Module operates through a structured flow that handles authentication, real-time communication, and notifications:
Authentication & Dashboard Access
Users authenticate through view available rooms and contacts.
Connection Initialization
Upon dashboard load, the application establishes a WebSocket connection to the signaling server and initializes Socket.io and WebRTC peer instances for real-time communication.
Room Navigation & Chat Interface
Users can join specific chat rooms where they access message history, send text messages, share files, and initiate video/audio calls with other participants. Some more features are available for both one-to-one and group chats.
Peer Discovery & WebRTC Signaling
When users calls peer using unique peer IDs, the signaling server facilitates the exchange of SDP offers/answers and ICE candidates through WebSocket events to establish peer connections.
Direct Peer-to-Peer Communication
After successful signaling negotiation, a direct WebRTC connection is established between peers, enabling high-quality audio and video streaming without server intermediation.
Real-time Chat & Presence Management
Text messages, typing indicators, new message with global notification and user presence updates are transmitted through the WebSocket channel, with message persistence handled via REST API endpoints for chat history.
Progressive Web App
