package generated protobuf code

[dckc]

It would be really handy to be able to just npm install rchain-probuf and get the stuff generated files with the rnode-grpc-js tool.

Package versions could correspond to rnode versions.

You can do the same with two commands.

# Install
npm i @tgrospic/rnode-grpc-js google-protobuf @grpc/grpc-js grpc-tools protobufjs

# Generate JS
node_modules/.bin/rnode-grpc --rnode-version v0.9.24

Why I'm not jumping on generating fixed versions is because I'm planing to build code generation directly from gRPC reflection which is now enabled in RNode. And also no additional tool will be necessary.

But having some clever GitHub action to generate fixed version would be nice to have.
In most version protobuf definitions are not changes so generating for each version is not necessary but I'm not sure what would be better approach.

Those 2 commands are pretty much what I did. Publishing the result in npm would save a few hours here and there for folks like me.

Putting it in a CDN along with a few more bits so that rchain is available with one <script src='https://'> would be really nice. (with subresource integrity, of course)

I haven't gone as far as putting the generated code in npm... or even as far as figuring out how to treat different directories as different packages in my project.

I wonder what gRPC reflection is or what its impact would be. Here's hoping for time to study it...

More info about gRPC reflection and what this means for RNode is on PR where reflection is enabled.

Basically, server can give the same information as in proto files so client code can be generated.
