Description

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 is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.

For any developers building web applications today within the React ecosystem, regardless of experience, this is a must have. The work developing efficient state management solutions using React that has been accomplished by this open-source community is astonishing. This book does an exceptional job breaking down limitations with React state management and solutions (Jotai, Zustand, Valtio, and React-Tracked) in a way that makes it easy to follow along, digest and process. I’m a visual learner, and this book did a pretty decent job communicating the code visually.I’ve been developing with React for 3-4 years and there definitely a lot of value in the knowledge this book provides.

This was a great read that covers a modern, micro, approach to state management using hooks from the basics to advanced concepts such as merging context with subscriptions. The author then dives into popular library examples using Zustand, Jotai, React Tracked and Valtio. This really helped me wrap my head around this hot topic.This book helped my team and I with selecting a library to use going forward as we refactor our code to use hooks.

Asked to name most prominent people working on React state, you would likely come up with Dan Abramov (Redux) and Michel Weststrate (MobX and Immer). But Daishi Kato should absolutely be on that list. He has created more(!) than 4 major libraries for React state, including Zustand, Jotai, Valtio and React-Tracked. And now he has written a book about React State, which I was eager to read.It was really interesting to get a guide from a creator of state libraries on approaching React state. He has deep insights on how to create state code that is performant, ergonomic and clear. Often when people approach state in React they end up with very inefficient (and difficult to optimise rendering) code or they use some very verbose and ossified approach like Redux. Daishi, has shown, in this book and in his libraries how we can actually have both ergonomic and performant state code.If you are intermediate or advanced React developer you should definitely read this book. The chapters are largely independent essays so you can dip in and out of the book. Even if you don't end up using one of his libraries you will likely learn a lot.

Micro State Management with React Hooks is a fantastic read for software developers who are looking to understand different approaches for managing application state. While this book is targeted to React developers, the introduction to module state and component can be used with any language that supports these features.The book begins with an introduction to the native React hooks useState and useReducer. Mr. Kato does a fantastic job of explaining how React manages state and how these hooks are used in web applications. If Mr. Kato wrote a book about the rest of the native React hooks, I would buy that in an instant. After looking at the two hooks, the book transitions on module state and its use with and without React Context. Having a strong understanding of how React natively manages state is important when going onto more advanced topics.The book does a great job of explaining the libraries Zustand, Jotai, Valtio, and React Tracked and how they are used within React as micro state managers. By first looking at how to manage state using native hooks, the reader can understand the use and benefits of using a custom library. Throughout the analysis of the custom libraries, it is evidence of the care and craft Mr. Kato puts into maintaining these libraries. His work allows React developers access to libraries with a flexible and simple API surface that focuses on developer experience. A good developer experience results in a performant and good user experience.I wish there was more written about the external libraries, particularly Zustand. That section was shorter than the others.Overall, this is a quick read and this book should be on the shelf of any modern React web dev.

I used Jotai for a few years already, so I was really interested to read this book. You can clearly see that it's a product of much love and care. There are tons of easily digestible code samples, it even includes github repo with ready-to-run projects and codesandbox links. I still think that the article that I wrote about Jotai vs Recoil went deeper into that particular subject :)I think Daishi does a great job documenting his libraries, and it's possible to get a lot of information from this book from open and free sources, but this book is all of that and more in one package :) the price is a bit steep, so just ask your employer to buy it for you :)disclaimer: I got an advance copy of this book for free to prepare this review
