Another commenter added the sentence I wish I had put in the original post. What I meant to say was, start with mostly pure components and just hold state in some top-level react components. Don't use react or flux. React makes it easy to share state between parent and child using props and callback registration which is perfectly fine to start.

When you find it hard to understand your state management within some parent react containers, or you're sharing a lot of state between siblings, consider flux or redux. Not before.
