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.
