global-state

Introduction I have been developing various global state libraries for React. For example: react-tracked react-hooks-global-state My main motivation is to eliminate selector functions that are only required for render optimization. Render optimization here means it avoids extra re-renders. An extra re-render is a re-render process that produces the same view result as before. Since Recoil is announced, I’m very interested in atom abstraction because it eliminates selector functions for render optimization and the API seems pretty intuitive....

Introduction React useContext is very handy to avoid prop drilling. It can be used to define global state or shared state that multiple components in the tree can access. However, useContext is not specifically designed for global state and there’s a caveat. Any change to context value propagates all useContext to re-render components. This post shows some example code about the problem and the solution with state usage tracking. Problem Let’s assume a person object as a state....

Background Ever since I learned Redux, I’ve been thinking an alternative integration of react and redux to the official react-redux library. The intuition behind it is that Redux is super simple which I like a lot, whereas react-redux is complex because of performance tuning. If you are developing a business product, the official react-redux is to go without a doubt, but if you are playing with creating a toy app or you are just starting learning Redux, you might want something more straightforward....
