Did your motivation ever suffered for company enforced tooling/stack?

I'm striving to be as adaptable as possible to not bitch if I have to use Angular insted of React or Java instead of Go but the stack which I was forced to use for the last two years is killing the joy I find in programming.

I'm talking about Spring WebFlux a stack which in theory is very promising (IO performances of NodeJS but in Java) but in practice is a pain to use: it makes polymorphism very hard forcing to rewrite tons of code, it significantly reduces your library choice, even after studying a damn book about it debugging remains a huge headache, unit testing often requires hacks and workarounds to be done...

Programming with it always feels like trying to fit a square peg in a round hole and I'm catching myself in procrastinating more and more, initially I feared I was burning out or losing my passion for the field but I noticed which the rare times I get to use a more canonical stack like .NET my motivation instantly returns but sadly I can use it only for few hours and then I return to WebFlux and my passion flees again.

I'm considering to look for another job but sadly lately I neglected my GitHub so I might have hard times in finding it.

I hate the fucking Spring WebFlux and the goddamn Project Reactor on which it depends!
Even debugging a simple CRUD microservice with simple business logic is such a pain in the ass, exception handling has a lot of "magic" implicit stuff which makes me waste hours in fucking trial & error and I have to use very little breakpoints because if a request is paused for more than few seconds it gets terminated.
I love functional programming but why shove it in fucking Java making me waste 90% of my time in trying to guessing what the fucking framework is doing, why not just use Scala which runs in the JVM? We don't even need compatibility with legacy code since it's a greenfield project!

And before you ask yes, I read a fucking book about Project Reactor and Java reactive programming and a lot of docs on Spring, Spring Boot and Spring Web Flux.

Spring WebFlux? pros, cons?

Write a book on advanced spring webflux / project reactor usage. Plenty of beginner guides and tutorials, but there's very little out there that's actually useful from a real world perspective.

It's me or the "Reactive Functional" Spring WebFlux is a stupid fad? It's hard to train new developers on it, a PITA to debug and there isn't any study which proves which it brings better performance compared to the classic Spring MVC.
