Formidable:

Clean and robust state management for React and React-like libs.

The library grew from the idea that state should be just as flexible as your React code; the state containers you build with freactal are just components, and you can compose them however you’d like. In this way, it attempts to address the often exponential relationship between application size and complexity in growing projects.

Like Flux and React in general, freactal builds on the principle of unidirectional flow of data. However, it does so in a way that feels idiomatic to ES2015+ and doesn’t get in your way.

The single state object, reducers, and selectors associated with Redux feels overwrought and often gets in the way. Freactal looks like an interesting alternative.
