Understanding the realtime web with websockets
summary
Explains that realtime means bounded latency not magic and demonstrates a working tiny.cc/realtime-voting demo built in Angular with Chart.js, wired to a hosted pub/sub realtime library using about three lines of WebSocket client code. Shows live votes (more than the room count), contrasts polling/long‑poll/HTTP2 with a persistent full‑duplex connection, names pub/sub and presence as implemented features, and shows the demo updating immediately so the system clearly works end to end.
