I’ve been trying to see if Phoenix supports HTTP/2 but I am not able to see any hint of a sign of negotiation or how to PUSH data over HTTP/2? It would be nice if, say, the View’s could specify mandatory files to be pushed to the browser based on their knowledge of the templates for example. Is th…

That’s a feature of Cowboy. Here’s the issue: HTTP/2.0 not supported · Issue #853 · ninenines/cowboy · GitHub

OK, so the situation is as follows: Cowboy has just got support for HTTP/2. I do not think it’s complete nor stable at the moment. HTTP/2 in Elixir is going to be mainly handled by Plug. Plug may require some significant changes to support HTTP/2 fully Plug/Phoenix guys are waiting for the final/s…

I figured that might be the case. I saw the issue in cowboy and thought HTTP/2 in it was dead as the issue appears dead and figured Phoenix was either waiting (fruitlessly based on the cowboy issue) on cowboy or was building their own but could not find anything for one way or the other. I am most…

I think on the Cowboy’s side, it’s going to be around 6 months to stabilize things from what I’ve been told. On Elixir’s side - not sure. I would expect preliminary protocol support first, with no assets push and only after some time inclusion of these. It needs to be handled on plug and phoenix le…

This is a weakest point of Erlang/Elixir web stack and could be a real challenge as implementing a quality http/2 server is a significantly more complex task than http/1.1 and it has very material impact on performance.

Here is the relevant issue: HTTP/2 support · Issue #258 · elixir-plug/plug · GitHub TL;DR - there are some developers exploring HTTP2 with Plug and Phoenix already (potatosalad is awesome). There are also production ready implementations of HTTP2 in Erlang (Chatterbox) beyond the one in Cowboy mast…

Thanx for the info subscribed to the issue :slight_smile:

Does anyone know what the latest is on this? It looks like plug was updated and works with Cowboy 2’s http/2 support. Are there any docs on using this?

There is a Cowboy2 Adapter being built for Plug at this moment actually (as well as maybe N2O support too). They seem to be working on push support and the new websocket API before full release, but it is testable now if you want. :slight_smile: https://github.com/elixir-plug/plug/issues/599 htt…
