TL;DR

WebTransport is the next-gen in-browser transport layer, riding on HTTP/2 and HTTP/3 to give you secure, multiplexed, bidirectional streams—both reliable and “fire-and-forget” unreliable ones. It fixes WebSocket’s handshake bloat and gRPC’s uphill battle on the web, offering low-latency, TLS-wrapped channels for everything from real-time gaming to live analytics.

In this deep-dive video, Hussein Nasser walks through why legacy hacks like HTTP/2 Push fizzled, how you actually upgrade connections, what you lose on HTTP/1.1 (spoiler: unreliable streams), and neat tricks like Extended Connect and proxying. Plus, if you’re hungry for more backend ninjutsu, he sprinkles in links to his Udemy courses, YouTube membership perks, and more—just in case you thought transport protocols were the only thing worth geeking out over.
