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.

More Data-Fetching Challenges

By now, you must be familiar with how React Query enables you to fetch data with the help of useQuery. You even learned how to deal with some common challenges that the server state brings you.

In this chapter, you will learn how to deal with some more server state challenges. You will understand how you can perform parallel queries and, in the process, get to know a variant of your useQuery hook that makes it easier, called useQueries.

You will again leverage QueryClient to deal with data prefetching, query invalidation, and query cancelation. You will even learn how to customize the methods you use to do these things by using some filters.

Pagination and infinite lists are common UI patterns, and you will leverage your knowledge to build them while learning more about useQuery and even meeting another variant called useInfiniteQuery.

By the end of this chapter, you will use the Devtools once again to look inside your queries and enhance your...
