WebTransport is a next-gen protocol layer riding on HTTP/2 and HTTP/3 that finally bridges the gaps left by WebSockets and gRPC. It lets you spin up secure, bidirectional, multiplexed streams—both reliable and unreliable—all over a single connection with minimal latency, TLS encryption baked in, and seamless integration with existing HTTP infrastructures.
In this video, Hussein Nasser walks through WebSockets’ and HTTP/2/3’s limitations, demos WebTransport’s upgrade process (and why it can’t fall back to HTTP/1.1), explains unreliable streaming, touches on HTTP/2 Push’s demise, and shows you how to proxy WebTransport. He also sprinkles in links to his Udemy courses (backend design patterns, networking, databases, NGINX, Python) and invites you to join his YouTube membership, buy him a coffee, or catch extra members-only content.
