That's an important note, indeed. Flux is a pattern as well as a library that represents an implementation of the pattern. Redux is another implementation (and a better one at that, in my opinion.) Specifically regarding Greyrest's concerns about many changes across many files - this can be reduced substantially using Redux.

With all that said, I still wouldn't consider FluxJS a bad place to start, as it provides a very clear example of what Flux really is, but once you understand how the pattern works you'll understand where the implementation is lacking and how Redux can help with that.

My main issue with Redux is that it is incredibly verbose compared the alternatives.

Also one single state is great for simple-moderately complex apps but it gets horrible for ones not build from scratch to work with that dynamic.

Something like Alt I find to be the best of both worlds tbh.
