WebTransport is a next-level protocol that brings multiplexed, bidirectional comms to the web by riding on HTTP/2 and HTTP/3. It supports both reliable and unreliable streams—all secured with TLS—so you can mix ultra-fast real-time data with rock-solid delivery on a single connection. Think of it as the Swiss Army knife of web transport, tackling limitations in WebSockets, gRPC, and old-school HTTP push.
In this video, Hussein walks through everything from why HTTP/2 push fizzled out to how to upgrade your app with extended CONNECT, proxy tips, and real-world caveats (YouTube notifications, anyone?). Along the way you’ll get a clear, informal tour of low-latency strategies, retrofit hacks for HTTP/1.1, and why WebTransport is poised to reboot how we build interactive backends.
