arrow_back Is Messenger really an anti-pattern?

Question

As far as I know it is possible to use RxJava or a C# equivalent to avoid using various MOM(Message Oriented Middleware) JMS and others as often - as possible.

1. The question is why different implementations of Messenger are called anti-pattern and why you should avoid using it?
2. When is the use of this pattern justified?

Answer 1

I don't see any connection between RxJava and JMS. This is a comparison of the rules of the road with the gearbox standards.

RxJava - about events inside the application.
JMS - about events between applications (maybe even in different languages and platforms).
