Yes, you can use a single client to make multiple simultaneous calls. In fact, this connection sharing is one of the major benefits of using gRPC.
You can't exactly check the current status, but you can use grpc.waitForClientReady, which calls your callback when either the client has finished attempting to connect or the deadline has passed, and passes an error if the client has not connected successfully. But using that function is generally unnecessary. If you make a call on a client that is not currently connected, it will do the right thing and start trying to connect.

I'm using grpc nodejs client in Express.js server app and I can not figure out if I can share a client object instance between multiple http request. I already figure out that I need to use promises to properly achieve Async calls. But that is another story. Each http request is managed by Express middelware stack, which define a set of functions which will be called before returning the response (in simplication). At some point I call let say client.sayHello(). Can I do that? Or do I need to have a pool of client object? Also how to check the status of client connection? If it is busy, ready, etc.?
