Offtopic; I also updated the openApi generator to use sttp3.

Could you merged newest master, it should solve problem with js tests.
It would be also great if you could write docs for jsoniter similar to one written for zio-json.
Please check if all files are correctly formatted with fmt.

I see one big problem with jsoniter and sttp and that is that sttp uses either and option a lot.
The it is possible in jsonIter to handle the option with the implicit def.
But the Either isn't really that safe so the user has to manually define an implicit val for every variant of either he wants to use.

So i think jsoniter needs to be improved for our usecase.

That can be quite problematic from user perspective. I am not that familiar with jsoniter to propose any workaround for this.
BTW I still see some merge conflicts could you resolve them ?

[borissmidt]

I could only make a workaround for 'option[t]'.
So i think changes have to be made to jsoniter before we can support it in this library.

For Either i couldn't really make a good workaround.

So we might better close the pr and maybe we can best keep the github issue open and comment these issues on there for future reference?

Hm I don't think we need any special Option/Either support. The options/eithers that appear in signatures are used to represent cases where either JSON parsing failed, or we received a non-200 response. So we don't typically need json codecs for these types, only for whatever is the "root" type.

[borissmidt]

I've removed the ambiguous Either tests and now i expect the use of asJsonEither so it is clear that you either have an error of type Left or a body of type Right.

[Pask423]

Great just resolve conflicts and I think we can merge it

[Pask423]

There is an error with downloading dependency

scala 3 macro support still needs to be added. I'll remove scala3 from the possible builds.
