Well I made the old HTTP/2 thread, so I guess it’s time I should make the HTTP/3 thread, lol. ^.^;
Cloudflare has rolled out HTTP/3 support. Things from curl to chrome itself already support HTTP/3, and firefox is adding support in an upcoming nightly. So how goes HTTP/3 support in phoenix (does the BEAM even have a QUIC library yet speaking of)?

The most complete I’ve seen for QUIC is GitHub - g-andrade/quack: Erlang implementation of Google QUIC protocol · GitHub which has been archived. Since HTTP/3 moves parts for flow control to the protocol QUIC that were in the application level with HTTP/2 I have meant to look at if an http/2 library, like GitHub - joedevivo/chatterbox: HTTP/2 Server for Erlang. Boy, that guy was a real chatterbox waddn't he? I didn't think he was ever going to stop with the story. · GitHub, would make sense as a starting point to pull some parts out of for build quic.
Also, TLS 1.3 is required though, isn’t it? I know it is at least partially available in OTP 22 but I don’t know that all necessary components are available.

I’m unsure if referencing HTTP/2 would help. QUIC adds things that are a lot like SCTP style things like pipelines, and those are why some parts of HTTP/2 can be dropped, just because it already exists in QUIC, but it’s not specific to HTTP/# at all as it is just a protocol layer and QUIC is useful for non-HTTP things.
And I do know QUIC requires TLS, and I’m pretty sure TLS 1.3 is required but uncertain on that last part… Though I bet HTTP/3 requires it regardless.

QUIC does indeed require TLS 1.3 (https://quicwg.org/base-drafts/draft-ietf-quic-http.html). And if I remember it was only experimentally added in OTP recently.
I would also be interested in QUIC in Elixir
josevalim
Oh wow, that was QUIC.

@josevalim you definitely spend too much time chatting with @tenderlove, it influences your puns.
My 2 cents would be that in addition to server (as in Cowboy most likely), support for HTTP client would be a nice to have at some point. I can see this will be a big speed up in some systems I saw, that do crazy stuff like protobuf files stored & read through S3, once AWS adds support to HTTP/3 on their end.
OvermindDL1
Yeah it’s looking nice so far. I was hesitant about QUIC being a more ‘generic’ non-http standard at first but they even have things like unreliable channels in the spec now too, it looks very nice! Like becoming a modern SCTP replacement!

Hi @josevalim and @chrismccord, with http/3 getting closer to becoming an RFC are there any plans to incorporate it into the Elixir ecosystem?

Neither José nor Chris maintain the webserver library used by phoenix.
This depends on cowboy:

For others that stumble in on this at some later date.
Cowboy is working on it?
