Thanks Arnaud! The key is in this line
https://github.com/jrudolph/akka-http-scala-js-websocket-chat/blob/239af857da2f174ea1624a84b0861c42cf4d1f2d/backend/src/main/scala/example/akkawschat/Webservice.scala#L33 so on the server side, the REST endpoint upgrades to a WebSocket `Flow` (i.e. akka streams API) via a directive. My legacy code is just an Actor, so I'll have to reimplement my marshalling layer and so on around this (or maybe marshalling is already handled). I've had a look at the Akka Streams documentation but it is not clear to me how to manually create a Flow from an Actor. I may have to read this a few more times, but I don't think it contains the information that I need... there doesn't appear to be a `Flow.actorRef` http://doc.akka.io/docs/akka-stream-and-http-experimental/1.0-RC3/scala/stream-integrations.html On Saturday, 23 May 2015 18:49:26 UTC+1, Arnaud Gourlay wrote: > > Hi Sam, > > I am also really interested in migrating from Wandoulabs to the new Akka > WS implementation. > So far this is the best example I could find > https://github.com/jrudolph/akka-http-scala-js-websocket-chat > > Hope this helps, > Arnaud > > On Saturday, May 23, 2015 at 12:38:22 PM UTC+2, Sam Halliday wrote: >> >> Hi all, >> >> I'm very excited that akka-io now has WebSocket support. >> >> In ENSIME, we're planning on using this wrapper over wandoulab's >> websockets >> >> https://github.com/smootoo/simple-spray-websockets >> >> to easily create a REST/WebSockets endpoint with JSON marshalling for a >> sealed family, with backpressure. >> >> Smootoo's wrapper works really well, and I have had the pleasure of using >> it in a corporate environment so I trust it to be stable. >> >> >> For future proofing, it would seem sensible to move to stock akka-io for >> WebSockets, so I'm considering sending a PR to retrofit the wrapper.
