RxJs

This item was not updated in last three versions of the Radar. Should it have appeared in one of the more recent editions, there is a good chance it remains pertinent. However, if the item dates back further, its relevance may have diminished and our current evaluation could vary. Regrettably, our capacity to consistently revisit items from past Radar editions is limited.

RX/JS aka reactive streams

RxJS is an implementation for the reactive programming paradigm which implements mostly the observer and iterator pattern and follows the functional programming ideas. The pattern actually got a renaissance because it's not completely new but has new implementations in many frameworks and languages like Angular, Akka, Spring and many more. Reason for that attention actually is (in the JavaScript world), that observables can be cancelled (by rules too) and observables can pass (stream) data on multiple events. Both aspects are not well realizable using promises e.g. and both were also detected as a huge limitation in the JavaScript community — and so it's worth to get an understanding for reactive programming in general.

We at AOE actually use RxJS in combination with Angular and can fully recommend the approach of observables.
