EntityStreamingSupport for two content types

[James Matlik]

I am trying to create an Akka-HTTP streaming service that supports both JSON and protobuf.

I am able to support both formats without streaming using Marshaller.oneOf(...) composition. However, I cannot seem to find something similar for EntityStreamingSupport.

Would anyone have pointers on how best to handle this?

Thank you,
James

Would any one have suggestions on how to support content negotiation with a steaming Akka-HTTP response? I know i can create content type specific URIs, but that doesn't lend itself to a well designed API.

I've still not been able to find how EntityStreamingSupport can support content negotiation.  Am I missing something obvious?

Much thanks,
James

James, have you seen this ticket: https://github.com/akka/akka-http/issues/424

There is an example there, which might help you.

Martynas,

Thank you for the pointer. There is a lot of good example code to digest there, if not just for understanding how people think in the context of marshallers. I was about to resort to creating my own entity to ByteString flows, but hopefully i can figure out a reasonable solution based on this.
