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 7: Use Case Scenario 1 – Zustand

So far, we have been exploring some basic patterns we can use to implement a global state in React. In this chapter, we will learn about a real implementation that is publicly available as a package, called Zustand.

Zustand ( is a tiny library primarily designed to create module state for React. It's based on an immutable update model, in which state objects can't be modified but always have to be newly created. Render optimization is done manually using selectors. It has a straightforward and yet powerful store creator interface.

In this chapter, we will explore how module state and subscriptions are used and see what the library API looks like.

In this chapter, we will cover the following topics:

  • Understanding module state and immutable state
  • Adding React hooks to optimize re-renders
  • Working with read state and update state
  • Handling structured data
  • Pros and...
