Micro State Management with React Hooks

State management in React is essentially the question of “how do we minimize the re-renders caused by state changes.” Since the problem of re-rendering is practically identical to the problem of performance optimization, you could say this book deals with performance optimization from React’s perspective. The book has you build your own global store for state management, while also explaining the pros and cons of the state management libraries that are popular as of 2025. It is a book worth reading even for those already familiar with React.

Of course, I’ve been developing with React for over three years now, and I did wonder whether I really needed to study this topic any further. So I started reading this book with the casual intention of taking a light break, but it turned out to be a book with plenty to learn from. In particular, I found the discussion of React Context to be a great help. When I first studied React, I understood Context as something you only use when building a library and just glossed over it. Looking back, that means my grasp of React’s fundamentals was shaky from the start. Something to reflect on.

That said, the explanations of the existing libraries may feel somewhat thin. But I think that if you want to learn about a specific library, you can simply open up that library’s source code.
