WebTransport shakes up web comms by riding on HTTP/2 and HTTP/3 to deliver secure, multiplexed, bidirectional streams—both reliable and “best-effort” unreliable—perfect for everything from chat apps to gaming. Forget wrestling with WebSockets’ quirks or gRPC’s heavy lift: you get low-latency, client/server-initiated channels with TLS baked in, all over protocols you already use.
In a deep-dive video, Hussein Nasser traces the evolution from plain HTTP to WebSockets, HTTP/2 push’s downfall, YouTube’s notification woes and backfill hacks, then shows how WebTransport’s Extended CONNECT works (and why HTTP/1.1 can’t do its unreliable streams). He wraps up with upgrade tips, proxying tricks and why this is the game-changer your real-time apps have been waiting for.
