For me it’s been experimental so far. I’ve not actually used Redux in these experiments, but I’m inspired by where Redux and Re-reselect has been leading me for the past two years or so. The pattern is a gold mine of interesting implications that I’m still discovering, such as real time collaboration, and speculative precomputation/prefetching.
As it moves all the focus from reducers to selectors, and has quite different requirements for how to do caching there, it’s led me to work on a custom selector library with quite different API from reselect/re-reselect. I’d like to release it when my experiments start to feel... less experimental.
