State Management with React Query

By: Daniel Afonso

Overview of this book

State management, a crucial aspect of the React ecosystem, has gained significant attention in recent times. While React offers various libraries and tools to handle state, each with different approaches and perspectives, one thing is clear: state management solutions for handling client state are not optimized for dealing with server state. React Query was created to address this issue of managing your server state, and this guide will equip you with the knowledge and skills needed to effectively use React Query for state management. Starting with a brief history of state management in the React ecosystem, you’ll find out what prompted the split from a global state to client and server state and thus understand the need for React Query. As you progress through the chapters, you'll see how React Query enables you to perform server state tasks such as fetching, caching, updating, and synchronizing your data with the server. But that’s not all; once you’ve mastered React Query, you’ll be able to apply this knowledge to handle server state with server-side rendering frameworks as well. You’ll also work with patterns to test your code by leveraging the testing library and Mock Service Worker. By the end of this book, you'll have gained a new perspective of state and be able to leverage React Query to overcome the obstacles associated with server state.

What Changes in React Query v5?

At the time of writing, version 5.0.0-alpha.1 of @tanstack/react-query has just been released. While it might take a couple of weeks for the stable version to be released, when this book is published, it might already be the version that installs by default every time you add React Query to your project.

To make sure you understand the changes that the content of this book may undergo after v5 is released, this bonus chapter was added.

This chapter might also serve as a helper to guide you when migrating from v4 to v5.

Once again, as a disclaimer, the snippets of this chapter were tested on version 5.0.0-alpha.1 of @tanstack/react-query. Some of these things might still change, or some new ones might show up. Either way, the snippets will be kept updated online in the next couple of months until a stable version is released. You can find them on the GitHub repository mentioned in the Technical requirements section.
