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 is React Query?

React Query is a protocol-agnostic collection of hooks for fetching, caching, and updating server state in React.

It was created by Tanner Linsley and is part of a collection of open source libraries called TanStack.

By default, React Query can also work with React Native out of the box, and it is written in TypeScript so that you can benefit from all its advantages, such as type narrowing and type inference.

Since version 4, React Query has been embedded in a collection of libraries called TanStack Query. TanStack Query made it possible to propagate all the amazing features of React Query to other frameworks and libraries, such as Vue, Solid, and Svelte.

React Query leverages queries and mutations to handle your server state. Upon reading this last sentence, you might wonder what queries and mutations are. I’ll show you some code in subsequent chapters so that you can see how React Query handles them, but first, let us learn about queries and...
