WebTransport
Noun · Development
Definitions
A browser API built on HTTP/3 and QUIC that supports both reliable bidirectional streams and unreliable datagram delivery between client and server, designed as a modern replacement for WebSockets with lower latency, multiplexing without head-of-line blocking, and native support for unordered/lossy transport.
In plain English: A newer, faster way for web apps to communicate with servers that supports both guaranteed and 'best effort' delivery of messages.
Example: "We switched from WebSockets to WebTransport for the multiplayer game — unreliable datagrams over QUIC let us send position updates without head-of-line blocking."
