Micro State Management with React Hooks

By: Daishi Kato

Overview of this book

State management is one of the most complex concepts in React. Traditionally, developers have used monolithic state management solutions. Thanks to React Hooks, micro state management is something tuned for moving your application from a monolith to a microservice. This book provides a hands-on approach to the implementation of micro state management that will have you up and running and productive in no time. You’ll learn basic patterns for state management in React and understand how to overcome the challenges encountered when you need to make the state global. Later chapters will show you how slicing a state into pieces is the way to overcome limitations. Using hooks, you'll see how you can easily reuse logic and have several solutions for specific domains, such as form state and server cache state. Finally, you'll explore how to use libraries such as Zustand, Jotai, and Valtio to organize state and manage development efficiently. By the end of this React book, you'll have learned how to choose the right global state management solution for your app requirement.

Chapter 10: Use Case Scenario 4 – React Tracked

React Tracked ( is a library for state usage tracking that optimizes re-renders automatically based on property access. It provides the same functionality to eliminate extra re-renders as Valtio, which we discussed in Chapter 9, Use Case Scenario 3 – Valtio.

React Tracked can be used with other state management libraries. The primary use case is useState or useReducer, but it can also be used with Redux (, Zustand (discussed in Chapter 7, Use Case Scenario 1 – Zustand), and other similar libraries.

In this chapter, we will again discuss optimizing re-renders with state usage tracking and compare related libraries. We will learn two usages of React Tracked, one with useState and the other with React Redux ( We will wrap up with a look at how React Tracked will work with the future version of React.

In this chapter, we will cover...
