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.

Using Valtio and MobX

Although the motivation is quite different, Valtio is often compared to MobX ( Usage-wise, there are some similarities in Valtio and MobX regarding their React binding. Both are based on mutable states and developers can directly mutate state, which results in similar usage. JavaScript is based on mutable objects, so the syntax of mutating an object is very natural and compact. This is a big win for mutable states compared to immutable states.

On the other hand, there is a difference in how they optimize renders. For render optimization, while Valtio uses a hook, MobX React uses a higher-order component (HoC):

In this section, we will convert a simple MobX example into Valtio. Then we will see the differences between the two.

Important Note

Conceptually, Valtio is comparable to Immer ( Both try to bridge immutable and mutable states. Valtio...
