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.

Part 2: Basic Approaches to the Global State

There are several approaches to using the global state effectively in React. Our focus is on optimizing re-renders. This is important because a global state can be used by multiple components. We describe three patterns – using Context, using Subscription, and using both Context and Subscription. We discuss how those patterns address the optimizing of re-renders.

This part comprises the following chapters:

  • Chapter 2, Using Local and Global States
  • Chapter 3, Sharing Component State with Context
  • Chapter 4, Sharing Module State with Subscription
  • Chapter 5, Sharing Component State with Context and Subscription
