cloudflow.akkastream.ServerStreamletLogic for accepting HTTP requests. Requires a Server to be passed in when it is created. cloudflow.akkastream.AkkaServerStreamlet extends cloudflow.akkastream.Server, which can be used for this purpose. When you define the logic inside the streamlet, you can just pass in this:

HttpServerLogic also predefined logics (HttpServerLogic.createDefault and HttpServerLogic.createDefaultStreaming) for accepting, transcoding, and writing to an outlet.

class TestHttpServer extends AkkaServerStreamlet {
  AvroOutlet<Data> outlet = AvroOutlet.<Data>create("out",  d -> d.name(), Data.class);
  Unmarshaller<ByteString, Data> fbu = Jackson.byteStringUnmarshaller(Data.class);

   public StreamletShape shape() {
     return StreamletShape.createWithOutlets(outlet);
   }

   public HttpServerLogic createLogic() {
     return new HttpServerLogic(this, getStreamletContext()) {
       Route createRoute() {
         // define HTTP route here
       }
     }
   }
