I don't know node, but, conceptually, Arrows [1] map to the steam concept very well (as always in Haskell, they are more general). The sugar in Haskell to use them similar to do-notion is really a joy to use.

I was exposed to them in the Haskell music library Euterpea in the Haskell School of Music [2]. The signal processing API uses arrows.
