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.

In this chapter, we learned about a library – React Tracked. This library has two purposes. One purpose is to replace the use case of React Context. The other purpose is to enhance the selector hook provided by some other libraries, such as React Redux.

Technically, the React Tracked library is not a global state library. It's to be used with state functions, such as useState and useReducer, or Redux. All React Tracked provides is a feature to optimize re-renders.

In the next chapter, we will compare the three libraries for global state, namely Zustand, Jotai, and Valtio, and discuss global state patterns to wrap up this book.
