[Question] support for HTTP/2?

[siegy22]

Hi guys.

I'm pretty new to crystal and kemal. I was wondering if there's any HTTP/2 support somehow built-in into the framework or in crystal language itself.

I looked through the http2 implementations list and didn't find anything about crystal.

So my question is: Is kemal and/or crystal capable of doing HTTP/2 communication? I think this could really be a breakthrough for kemal to become popular.

Keep up the good work! 💚

EDIT:
If this issue is misplaced, please tell me where I should move it to. 😁

I found a ongoing discussion on the crystal repo: crystal-lang/crystal#2125

And a (yet to be finshed) initial implementation of the HTTP2 protocol in crystal: https://github.com/ysbaddaden/http2

Any update on this?
I am hoping to use my frontend as static html/js client which connects to a Kemal based api via https. Having http/2 support would be super good.

No update here, unfortunately. The stdlib HTTP stuff needs a bit of a redesign with HTTP/2 in mind.

For now, using nginx or another reverse proxy in front of crystal web apps is still strongly advised, and nginx with HTTP/2 support is almost as good as native H2 support in the application.
