WebTransport

[LeviPesin]

Description

WebTransport is an API for accesing HTTP/3 protocol in browser, similar to WebSockets but with very nice UDP features like unreliable and out-of-order (but very much faster) delivery.

Rationale

It is very useful in web games, because it allows for a very fast (but unreliable) messaging.

It is enabled in desktop Chrome, Edge, and Opera, and mobile Samsung Internet and Android Browser.

WebTransport is a P4 for Google's closure library

"This is probably relevant to goog.net somehow? (but I'm not particularly familiar with that part of the library)"

In the MDN short survey on APIs & JavaScript, "WebTransport" was selected by ~11% of survey takers, putting it in the bottom third of options. (There is some uncertainty as with any survey data.)

Thank you for proposing WebTransport for inclusion in Interop 2023.

We wanted to let you know that this proposal was not selected to be part of Interop this year. We had many strong proposals, and could not accept them all. This should not be taken as a comment on the technology as a whole, and resubmitting a proposal for this feature as part of a future round of Interop would be welcome.

For an overview of our process, see the proposal selection summary. Thank you again for contributing to Interop 2023!
