Video Conferencing App

Real-time video conferencing app built with Node.js, Socket.IO, and EJS server-side rendering. Users create or join rooms via unique IDs; the server (server.js) brokers WebRTC peer connections. EJS templates (views/) render the UI; public/ serves client-side JS and CSS. Deployed live on Render.

🔴 The Problem
▸

Needed a lightweight conferencing solution without requiring any login or external service

▸

WebRTC setup requires a reliable signalling layer to exchange SDP offers

✅ The Solution
▸

Socket.IO handles the signalling handshake between peers; unique room IDs pair callers

▸

EJS templates render the UI server-side; client JS establishes the WebRTC peer connection

📈 Impact & Results
▸

Works in any modern browser — no plugin or account required

▸

Deployed live on Render — shareable room link starts a call instantly

▸

Room-based routing means multiple concurrent calls on the same server
