WebTransport is basically the next-gen way to get real-time, bidirectional communication on the web. It fixes WebSockets’ and gRPC’s quirks by letting you multiplex reliable and unreliable streams over HTTP/2 and HTTP/3, all wrapped in TLS for security. That means low-latency, pushy interactions without opening zillions of connections.
In his deep-dive video, Hussein walks us through the journey from “the simple web” to WebSockets, HTTP/2/3, gRPC, and finally WebTransport—covering unreliable streams, upgrade paths, why HTTP/2 push fizzled out and why YouTube notifications often go haywire. He peppers the talk with practical demos, proxy tips and a stack of links to his Udemy courses on backend engineering, networking, databases and more.
