Don't know what to write here really.

Connection is closing before i write response to it.

First of all here is my GRPC-Java Client.

StreamObserver<Request> requestObserver = asyncStub.status(new StreamObserver<Reply>() {
...
Observer... on next on error on completed part here. }
...
try catches surrounded below in actuality.
requestObserver.onNext(newMessage(message));
requestObserver.onCompleted();

My GRPC-Node Server

call.on('data', () => { do_something(); console.log('Data'); call.write(something); })
call.on('end', () => { console.log('End'); call.end(); } )

I put System.out.println(“Completed”) on requestObserver’s onCompleted. So i get a message when it completes.

Then i put console.log() on node’s each call.on just before call.write and call.end

Problem is, connection is closing before the call.write(). I see End message first.

It seems like call.on(‘end’, ()) is working before call.on(‘data’, ())

😦 I didn’t understand anything.

yes but documentation still would be helpful for those having brain inflamation like me.

Everything I said applies to built in Node streams in general, and how they interact with async functions. None of it is specific to gRPC.
