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.

Understanding when to use Jotai and Recoil

Jotai's API is highly inspired by Recoil. In the beginning, it's intentionally designed to help migration from Recoil to Jotai. In this section, we will see a comparison by converting an example with Recoil into Jotai. Then, we will discuss the differences between the two.

Example with Recoil and Jotai

Let's look at the Recoil tutorial at https://recoiljs.org/docs/introduction/getting-started and see how an example in the Recoil tutorial is converted to Jotai.

To start with the Recoil example, we need to import some functions from the Recoil library:

import {
  RecoilRoot,
  atom,
  selector,
  useRecoilState,
  useRecoilValue,
} from "recoil";

There are five of them used in this example.

The first state for the text string is created with the atom function:

const textState = atom({
  key: "textState",
  default: &quot...
