gRPC / node:http2

[julienp]

Version: Deno 1.42.1

I am experimenting with making deno a runtime for pulumi/pulumi, which relies heavily on gRPC.

I think recent work on the node:http2 polyfill gets us pretty close, and looking at other issues I see people reporting at least some success with gRPC. However I can't quite get it to work.

I have a small repro here https://github.com/julienp/deno-grpc-bug which highlights a couple issues:

• It looks like grpc-js is sending the status code as a number, but deno wants this to be a string https://github.com/grpc/grpc-node/blob/be40682090bd7481f6136abac3f817bcf7b3fd32/packages/grpc-js/src/server-interceptors.ts#L815
• If I manually patch that grpc-js to convert the code to a string, I get past this issue, however the client never receives the response. Looking at Wireshark and sprinkling logs through grpc-js, I see that the response is delivered on the transport level, but is not delivered to the client code. My suspicion is that the stream ending is not properly detected.
• If I run against a go server, it complains about received an illegal stream id: 1 (complete logs)

@julienp this problem should now be fixed as we have all the grpc/grpc-js client-side examples covered. The issue for tracking server is progress is now: #23714. Let's close this one and continue in the issue above. Can I ask you to open a new issue if you hit any more problems?
