## Overview

This is a hands-on RTC learning reference, not a single production service. Its runnable workflow is a browser connecting to the unified Node server, which serves a dashboard and demonstrates long polling, SSE, and WebSockets; separate files provide standalone versions. The README also documents short polling, broker-based WebSocket scaling, and WebRTC signaling and peer media as conceptual branches. Those latter capabilities are documented rather than implemented in the sampled runtime. The dashboard source was not sampled, so its protocol-specific wiring is not inferred.

Main entry points: [`server.js`](https://github.com/iamakashtechie/webrtc-learning/blob/main/server.js) (Unified HTTP Server), [`README.md`](https://github.com/iamakashtechie/webrtc-learning/blob/main/README.md) (Signaling Server), [`public/index.html`](https://github.com/iamakashtechie/webrtc-learning/blob/main/public/index.html) (Testing Dashboard), [`longPolling.js`](https://github.com/iamakashtechie/webrtc-learning/blob/main/longPolling.js) (Standalone Long Poll)
