WebTransport: The New Real-Time Hero

WebTransport is the next-gen, all-in-one web protocol that fixes what WebSockets and gRPC couldn’t—think reliable and unreliable streams, true bidirectional channels, TLS-secure multiplexing, and super low latency, all riding on top of HTTP/2/3. It’s designed for real-time apps, handles multiple data flows over a single connection, and even works around the quirks that killed HTTP/2 Push and left services like YouTube struggling with notifications.

In Hussein Nasser’s deep dive, you’ll see how WebTransport negotiates over HTTP/2 vs. HTTP/3, why it flat-out won’t run on HTTP/1.1, how to handle upgrades, and even tips on proxying it. If you’re building anything from live games to collaborative docs, this protocol just might be the game-changer you’ve been waiting for.
