Master WebSockets in this crash course, moving from core theory to building a high-frequency "Broadcast Engine." Learn how to ingest data from admin sources or APIs to deliver live match scores, commentary, and ball-by-ball updates to 100,000+ simultaneous users with sub-second latency. This project covers everything from the initial handshake to deployment, demonstrating how to architect a system that broadcasts real-time data to millions of clients without crashing the server.
