GopherOmegle

GopherOmegle is a high-performance, open-source 1:1 video chat application inspired by the classic Omegle platform. Built with modern technologies, simplify real-time communication with a robust Go backend and a sleek React frontend.

Architecture

The system follows a client-server architecture with peer-to-peer (P2P) WebRTC connections for media streaming.

• Frontend (React + Vite): Connects via HTTPS/WSS to the Load Balancer.
• Backend (Go + Gin): Handles API and WebSocket signaling.
• Backend Services:
  • JWT Auth Middleware: Secure session management.
  • PostgreSQL: Persistent data storage.
  • WebSocket Hub: Manages real-time signaling.
• P2P Media Stream: Direct WebRTC video/audio stream between users.

Flow

1. Authentication: Users login/register via REST API to receive a JWT.
2. Connection: Client connects to WebSocket with the JWT.
3. Matchmaking: Backend places user in a queue. When 2 users are available, a Room is created.
4. Signaling: Backend facilitates the exchange of SDP offers/answers and ICE candidates via WebSocket.
5. Streaming: Once signaled, clients establish a direct P2P WebRTC connection for low-latency video and audio.
