This is interesting for sure, but I don't think we'd go ahead with this without having it also working with Bandit and without it properly handling the auth token (see comment).
On the JS side, you can already pass a custom transport when constructing the socket, so maybe what we could have for the time being is a better way to do custom server side transports without needing all the code in Phoenix itself? (Not sure how to best do that though)

Is there any browser that has WebTransport but no TextEncoder?

It seems the check is not needed

Note that the whole idea behind the auth token is that it's NOT included in query parameters, as those are often part of access logs.
It seems like this is coming at some point: w3c/webtransport#713
Fair. I treat this PR as an exploration. The tech is not yet ready for wide deployment
I haven't checked the custom transports so I cant tell they are flexible enough. IMO when the tech matures phoenix would need to adopt it as an officially supported transport |
I agree :) |

This PR adds experimental WebTransport support in phoenix using cowboy backend with native quicer HTTP 3 library
Widespread WebTransport adoption on the browser side is still hindered by Safari (support landing on 26.4) (see https://caniuse.com/webtransport), cowboy HTTP 3 support is still immature and on the infra side QUIC traffic is another story so I don't expect this being a big priority soon
This repo https://github.com/lukaszsamson/phoenix_webtransport_demo has a demo app
