@iamszabo Do I understand correctly that WebFlux doesn’t use Rx at all and instead, invents its own copy of it?

[Ben]

They use Reactor which is a spring project but I think you can plug in Rx if you want to use that.

[cedric]

Not sure how since the types would not be compatible

[Ben]

It uses Reactive Streams so anything that implements that can be used. https://docs.spring.io/spring-framework/docs/5.0.x/spring-framework-reference/web-reactive.html#webflux-reactive-api

[Ben]

So you just pull in https://github.com/ReactiveX/RxJavaReactiveStreams to use Rx

[cedric]

Ah ok

The cornerstone of WebFlux is indeed Reactive Streams, which allows us to adapt to any non-blocking API : RxJava 1, RxJava 2, CompletableFuture, Akka, Coroutines. Reactor is leveraging most Reactive extensions conventions but using RxJava was not possible for us. Flux + Mono types is different from RxJava 2 type strategy, we are Java 8+, need to garantee API stability from a Pivotal POV, we need specific features like context that RxJava does not have, etc. Also keep in mind that Reactor is a co-production between Stéphane Maldini (Pivotal) and David Karnok (RxJava lead). Last but not least, Reactor is not just Reactor Core, Reactor Netty and other parts of the ecosystem.
