how to detect a client connected to server grpc?

[Constantine]

Hi :)

I'm using nodejs grpc server. My clients are android devices and iOS devices. I want to detect when a new user connected to the server and emit a special event. I searched the doc but I couldn't find anything! Is it possible?

Thank you!

I would make it explicit and just send a small "connected" message from the client, along the philosophy of "you're not really connected until you're able to send a message"

I created a nodejs client. But my client returns a null object but there is no error about the connection!
