Clients should remain Scala.js compatible

[juanpedromoreno]

We should split the rpc core in order to make the client part compatible with Scala.js.

Interesting findings by @calvellido :)

@juanpedromoreno could you clarify how this issue relates to #73? Thanks!

[juanpedromoreno]

As we will be deriving HTTP services with its auto-derived clients, those will be Scala.js compatible, so likely this issue could be closed once we get the HTTP features.

@juanpedromoreno, @raulraja is it correct to understand this task is about

1. generating client code that compiles to scalajs
2. not necessarily generating full client stubs for both avro and protobuf
3. clearly not about providing the actual runtime for execution of the stubs (for example ScalaPB has the only scalajs GRPC runtime I know)

Please advise in these respects and also what it is necessary to bridge the gap to become able to actually call mu services from web clients compiled with scalajs over https, using either / both avro and protobuf.

Trying to confirm that mu only focuses on providing the "server side" (runtime, generated stubs, etc) and not trying to also provide the clients.

@SemanticBeeng Thanks for bringing all these questions up.
Under the context of all the issues labeled as http we are implementing the auto derivation of HTTP server and HTTP client for a given schema/protocol.
What this issue proposes is, due to the http4s clients are compatible with scalajs, the derivation of the this part should be in a diferent sbt module, and thus, those projects that are acting as Mu clients only need to add mu-http-client as a dependency, whose artifact must be compatible to scalajs.

Side note: We are not using ScalaPB to convert the idl into the http clients.

I hope this answers your questions.

http4s clients are compatible with scalajs

Thank you for following up.
So #593 is "done" in this sense, then?

Dup of #593
