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.

What this book covers

Chapter 1, What Is Micro State Management with React Hooks?, explains how React Hooks help to deal with states. This allows us to have more purpose-specific solutions.

Chapter 2, Using Local and Global States, discusses two types of states. Local states are often used and preferable. Global states are used to share states between multiple components.

Chapter 3, Sharing Component State with Context, describes how Context is the primary method to deal with global states and how it works within React life cycles. We need some patterns to avoid extra re-renders.

Chapter 4, Sharing Module State with Subscription, explains how module state is another method for global state. It works outside React life cycles. We need to connect the module state to React components, but a Subscription to the module state makes it easier to optimize re-renders.

Chapter 5, Sharing Component State with Context and Subscription, shows another approach for the global state by using both Context and Subscription. It works within React life cycles and avoids extra re-renders.

Chapter 6, Introducing Global State Libraries, introduces some libraries with various approaches for solving common problems in global states.

Chapter 7, Use Case Scenario 1 – Zustand, discusses a library, Zustand, used to create a module state that can be used in React.

Chapter 8, Use Case Scenario 2 – Jotai, is about a library, Jotai, based on Context and the atomic data model. It can optimize re-renders too.

Chapter 9, Use Case Scenario 3 – Valtio, discusses a library, Valtio, for mutable module states. It automatically optimizes re-renders.

Chapter 10, Use Case Scenario 4 – React Tracked, discusses a library, React Tracked, used to enable the automatic render optimization for some other libraries, such as Context, Zustand, and React-Redux.

Chapter 11, Similarities and Differences between Three Global State Libraries, compares the three global state libraries – Zustand, Jotai, and Valtio.
