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.

Using the different features of Jotai

So far, we've learned some basics of the Jotai library. There are some more basic features that we will cover in this section. These features are necessary if you need to deal with complex scenarios. We'll also briefly introduce some advanced features whose use cases are out of the scope of this book.

In this section, we'll discuss the following topics:

  • Defining the write function of atoms
  • Using action atoms
  • Understanding the onMount option of atoms
  • Introducing the jotai/utils bundle
  • Understanding library usage
  • Introduction to more advanced features

Let's take a look at each one now.

Defining the write function of atoms

We have seen how to create a derived atom. For example, doubledCountAtom with countAtom is defined in the Understanding how Jotai works to store atom values section, as follows:

const countAtom = atom(0);
const doubledCountAtom = atom(
  (get) => get...
