Disconnect/close/cancel from the client side

Hi, I can’t find any method to disconnect the client as per my command. Using an example snippet here -

function doSomething () {
    var SomeServiceClient = xxx.yyy_service.SomeServiceClient;
    var client = new SomeServiceClient('http://localhost:8080', null, null);
    status = client.testme(parameters, {},function (err, response) {
        console.log('testme response: ' + response);
    });
    // how do i disconnect the client?
}

The problem I’m encountering is - user clicks a button, I make a request to the gRPC server and start receiving data in a stream. If the user clicks again, I start receiving data again in another stream. I want to disconnect any previous streams/connections so that I can receive only one stream at a time. Any help/suggestions would be greatly appreciated! (I know I could disable the click till the stream is finished, but that’s not what I’m looking for.)

How do you cancel a request when using the promise client? as the client.request only returns a promise?

In your snippet above, you can call status.cancel().
