React is awesome, but is just a view library, when we need to manage state, there is Redux.js. The ecosystem of redux is big, complex and hard to integrate. That's why we choose to create hydux. Hydux is simple, the main idea is from Elm, a pure functional vdom-based framework for front-end. We seperate the whole app with state, actions and views. Which means not only our views are a tree, but also our state and actions. Reuse state and actions are just like reuse react components, no need to consider dependences.
