sounds like a straightforward question, but i cannot find the answer (probably because the '2.0' is interpreted as Akka's version when searching for 'how to do HTTP/2.0 with Akka-HTTP').

it seems like akka-http does have a construct for HttpProtocols, but it only has HTTP 1.0 and HTTP 1.1.

  • AFAIK Akka http is not yet compliant with HTTP/2.0. – cmbaxter Jul 30 '16 at 10:45

    recently akka-http2-support has appeared on master branch of akka-http project https://github.com/akka/akka-http . Seems soon it will be available. – maks Nov 13 '16 at 00:14
  • It does support http2 http://doc.akka.io/docs/akka-http/current/release-notes.html#akka-http2-support – juanpavergara Mar 17 '17 at 22:39
  • @juanpavergara The link you provide says "(not yet surfaced in user API)". Akka-http 10.0.5 does _not_ yet support HTTP/2 https://github.com/akka/akka-http/issues/244 – akauppi Mar 24 '17 at 11:13

The support is now official. Akka has a server side in preview mode for the moment :

Akka-http 10.0.5 does not support HTTP/2, yet. You can track the work here.

    Update: "For reference, people interested in tracking progress and helping out should track this tag on github: https://github.com/akka/akka-http/labels/t%3Ahttp2 " (from https://github.com/akka/akka-http/issues/111 ) – akauppi Jun 25 '17 at 09:48

Akka-http 10.1.1 supports server-side HTTP/2 in preview mode (HTTPS only): https://doc.akka.io/docs/akka-http/current/server-side/http2.html

@akauppi's link still shows many features are still in progress (including client side support)

Client http/2 support appears rare among all Scala libraries currently - checkout (for both client and server side http/2): https://github.com/criteo/lolhttp
