WebTransport: Low-Latency Bidirectional Messaging API

a year ago

WebTransport is a web API using HTTP/3 for bidirectional client-server communication.
Supports unreliable datagram APIs (low-latency, unordered) and reliable stream APIs (ordered data transfer).
Use cases include gaming state updates, media streaming, and server notifications.
WebTransport is not a direct replacement for WebSockets or UDP Socket API but offers advantages like no head-of-line blocking.
Comparison with WebRTC data channels shows WebTransport requires less setup and is more web developer-friendly.
Current browser support is limited, with Chromium 97 being the first to launch WebTransport.
The API is designed around modern web primitives like Streams API and Promises.
Includes methods for datagrams, unidirectional, and bidirectional streams.
Privacy and security considerations are addressed in the draft specification.
Feedback channels include GitHub, Chrome bug tracker, and social media for public support.
