WebTransport is a cutting-edge framework for multiplexed, secure, bidirectional real-time comms over HTTP/2 and HTTP/3. It smashes together reliable and unreliable streams in one connection, giving you the speed of UDP-style messaging and the safety of TCP-style delivery without juggling separate sockets. Imagine chat, gaming, or live data feeds running on TLS-protected streams that let clients push data as easily as servers do—no more half-baked hacks or polling madness.
In the video, Hussein Nasser breaks down WebTransport’s evolution (from WebSockets’ quirks and gRPC’s limits), explains how to upgrade existing HTTP connections, and even dives into why HTTP/2 push flopped. You’ll learn about extended CONNECT, backfill strategies, and proxying tricks to get WebTransport running everywhere—seriously, it’s the Swiss Army knife your backend’s been waiting for.
