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.

Future prospects

The implementation of React Tracked depends on two internal libraries:

As we learned in the Using React Tracked with useState and useReducer section and the Using React Tracked with React Redux section, there are two ways to use React Tracked. The first way is via React Context with createContainer and the second is via React Redux with createTrackedSelector. The base function is createTrackedSelector, which is implemented with the proxy-compare library. The createContainer function is a higher abstraction, which is implemented with createTrackedSelector and the use-context-selector library.

In terms of the use of Context in React Tracked, the use-context-selector library is important. What is the role of use-context-selector? It provides a useContextSelector hook. As we learned in the Understanding Context section in...
