Rpc is not exported by ts-proto as it previously was about ts-proto

[stephenh]

@ws-gregm huh, we did just ship #1027 cc @dasco144 , but I don't think importing Rpc from ts-proto was really working on purpose, previously.

I.e. the ts-proto package is meant to be "the code generator you run at build-time" and not really the "the runtime code / dependency your app uses to encode/decode data".

I.e. we should be generating a interface Rpc into the output of ts-proto, so that when you package up the AuthorMessage / BookMessage / etc messages, the interface Rpc type should be included in that.

So, dunno, I'm curious to learn if/how this was actually working before, but I think it's intended that you import Rpc from the ts-proto-generated code and not the ts-proto dependency itself.

Hey @stephenh thanks so much for getting back so quickly. Do you have an example of what this would look like or how I would use this?

so that when you package up the AuthorMessage / BookMessage / etc messages, the interface Rpc type should be included in that

Hi @ws-gregm , sorry, an example of what? For better or worse, going through ts-proto's integration/ directory and looking for usages that are most similar to what you're trying to do is the best bet.

@stephenh Digging through there - it's not clear to me how to

1. instantiate a grpc client
2. Specify ip and port to grpc server

[stephenh]

@ws-gregm if you're using grpc-js, this example is probably a good one to copy/paste from:

https://github.com/stephenh/ts-proto/blob/main/integration/grpc-js/grpc-js-test.ts#L152

I'm going to close this issue out b/c I don't think it's related to a breaking change in the exports. If you'd like to submit any PRs to improve the docs for ^, that'd be great, thanks!

Hey @stephenh, maybe it's best if I open a discussion but responding here for context. I experimented with TestClient. It appears that TestClient doesn't include methods that return promises. Meanwhile, the benefit of the generated *ClientImpl classes is that they return promises.. To use the *ClientImpl, I would need to craft this mystical rpc object. There doesn't appear to be any obvious guidance on this matter in the tests. From my POV, the general aim is to drive generated client methods that return promises. What's the typical way to do this? Also, I eventually need to expose methods that return a stream. I tried combing through existing projects that use ts-proto and I'm not find clear guidance there either.
