Unable to connect to Unix socket using node-grpc client

I am trying to communicate with a server that is listening on a unix socket - if I use TCP I have no issues, but after much effort have been unable to get it working with the unix socket. Code is

    const BIND_SOCKET = '/tmp/collector.sock';
    const BIND_TCP = ':9832'; // works fine if I use this for client + server
    const PROTO_PATH = './Collector.proto';
    const collector = grpc.load({ root: __dirname, file: PROTO_PATH }).collectorv1;

    this.client = new collector.Collector(BIND_SOCKET, grpc.credentials.createInsecure());

I have tried many variations on the socket, such as unix:/tmp/collector.sock and many others I have found online. However none of them work and my write call simply hangs forever, regardless of whether the server is active and listening on the port.

I am using grpc version 1.10.1

I think we can consider this issue to be an actual feature request 😃 Also it might be easier for us to implement this using the pure-javascript version of the library.

@entropitor : Problem with authority header is a story of its own. It is a source of various interoperability issues because the spec does not say what authority header should be if used over UDS.
