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.

Pros and cons of this approach and library

Let's discuss the pros and cons of using Zustand or any other libraries to implement 
this approach.

To recap, the following are the reading and writing states of Zustand:

  • Reading state: This utilizes selector functions to optimize re-renders.
  • Writing state: This is based on the immutable state model.

The key point is that React is based on object immutability for optimization. One example is useState. React optimizes re-renders with object referential equality based on immutability. The following example illustrates this behavior:

const countObj = { value: 0 };
const Component = () => {
  const [count, setCount] = useState(countObj);
  const handleClick = () => {
  useEffect(() => {
    console.log("component updated");
  return (
