Never made any OpenSource lib, but I always had that gut feeling you are talking about here:

"Unfortunately, even for me, a library author, it's hard to evaluate all of them properly. It would take just too much time and you never know where the real problems in any framework lay before you get neck-deep in code. And then you're too far to switch to another framework anyway."

Putting that aside, to me RxJS and especially Cycle.js are "1 abstraction level above" React & friends. (Cycle can be used via React.)

What do you think about these?
