How to retrieve response trailers in grpc-web calls

[Rob Cecil]

Hi, I'm using the generated js code that uses Promises along with TS.

Example method:

  getMenu(

    request: Menu_pb.GetMenuRequest,

    metadata?: grpcWeb.Metadata

  ): Promise<Menu_pb.Menu>;

I have been passing in the deadline via Metadata in the last argument of the generated methods.

How do I interrogate the response trailers using the Promise API ?

Thanks

Ha, I found an answer:

Be nice if these sort of details were pulled out issues into the main documentation.
