Description

This is a poc of how to use buf to generate the proto files from the remote repo.
It's similar to the experimentation from the go-sdk.

In a nutshell:

1. Using buf, the protos for generation are referenced remotely from dapr/dapr - so not copied locally anymore
2. There's a manual "lock file" that ensures that the generation is happening against a committed remote sha (this could be replaced by buf's own locking mechanism if dapr/dapr supports it).
3. Ideally CI would ensure that the generated files are up to date and unmodified.

JS is not a language I'm familiar with, but I tried to keep the generation using the same pattern (ts/es), but different outputs can be configured by using/combining different plugins in buf.gen.yaml.

This is not currently generating proto dependencies like google timestamppb for example - I think there's probably a way to generate them, but at the same time I think they can be consumed versioned from https://www.npmjs.com/package/google-protobuf
