re: RxJS Transducer - Harness the Power of RxJS Operators VIEW POST

re: Nice one, is this the best implementation of Transducers in TS(or even all of JS) right now, or only popular because of it's part of RxJS? In any ...

Hi, thanks for replying. I only just created the library a few days ago, so I wouldn't say it is popular (yet) :-)
But if you have a project where you are already using RxJS and are already familiar with the operators, I think it has a low entry barrier.

  1. So far it always drains to an array, so the only way to do that is new Map(transducer(xxx)(yyy)) which has a performance penalty of first allocating the array.
  2. You can't at the moment. But it is a good suggestion. I think I can solve both issues by allowing the transducer to produce a lazy iterable instead. I will look into that.

Thanks for the feedback!


My apologies.
I assumed it was a not-even-recently-added part of the ancient RxJS behemoth.
Guess that's what I get for not clicking the I have written a transducer function link :)
I see this post was more of a camouflaged release announcement than a tutorial for an established package. 😉
I think that the line that sent me on this path the most was

RxJS will in fact process streams synchronously when possible

Oh. I will make it more clear that this is a new library, and make it less camouflaged :-)
