Video Conference

A video conferencing system built around an SFU (Selective Forwarding Unit) architecture.
It uses WebRTC for real-time audio/video, WebSockets and gRPC for signaling, MongoDB for room and user state, and cookie-based authentication for secure session management.
Designed to support multi-party meetings with efficient media routing and a scalable backend.

How to Run

Backend

1. Update your .env in /backend:

   • Run a local MongoDB instance.
   • Add its connection URL and database name to .env.
   • Configure the ports you want for the signaling and SFU servers.

2. Start the backend services:

   cd backend
   go run cmd/signaling/main.go
   go run cmd/sfu/main.go

Frontend

Start frontend:

cd frontend
yarn install
yarn dev

Secured Backend (optional):

mkcert -install
mkcert -key-file dev.key -cert-file dev.crt

Then update your key and cert url in your .env file in /backend for TLS configuration

Multi devices testing (optional):

To test on other devices, expose your local frontend with a free tunneling service:

cloudflared tunnel --url [your local frontend url]
