Reactive API

[janekolszak]

Hi, Is there a plan to add reactive api? Otherwise modern Spring webflux servers would need to re implement this project. This seems to be a matter of using another generator. Maybe in a separate repository.

WebClient is reactive: https://docs.spring.io/spring-framework/docs/current/reference/html/web-reactive.html#webflux-client

OpenAPI can generate webclient: https://www.baeldung.com/spring-boot-rest-client-swagger-codegen

Thanks!

Jan! Nice to see you still around - we currently don't have plans for that but it would generally be possible to generate SDKs with that client too. What do you not like about the current implementation?

Hi, nice to see how you've grown all these years! :)

I'm integrating hydra with a webflux server. But you're right I can generate client myself. Should I take the openapi.yaml file from this repo or is there a newer one somewhere else?

@janekolszak Try this, easy way to warp a callback to Mono:

@Suppress("EmptyFunctionBlock")
private inline fun <reified T> toMono(crossinline fn: (ApiCallback<T>) -> Unit): Mono<T> {
  return Mono.create { sink: MonoSink<T> ->
    try {
      fn(
        object : ApiCallback<T> {
          override fun onFailure(e: ApiException, i: Int, map: Map<String, List<String>>) {
            sink.error(e)
          }

          override fun onSuccess(t: T, i: Int, map: Map<String, List<String>>) {
            sink.success(t)
          }

          override fun onUploadProgress(l: Long, l1: Long, b: Boolean) {}
          override fun onDownloadProgress(l: Long, l1: Long, b: Boolean) {}
        })
    } catch (e: ApiException) {
      sink.error(e)
    }
  }
}

Thanks, I ended up copying openapi.yaml and generating webclient API myself. Works like a charm.
