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.

Part 2: Managing Server State with React Query


In this chapter, we learned more about using the useQuery hook to solve some common challenges we are presented with when dealing with the server state. By now, you can handle all your data fetching needs and do it easily.

You learned about parallel queries and learned you could manually build these queries with useQuery. You were also introduced to one alternative of the useQuery hook: useQueries. With it, you learned how to build dynamic parallel queries.

You got to learn more about some methods of QueryClient that allow you to prefetch, cancel, and invalidate queries and also understood how you can leverage QueryFilters to customize the query matching used in these methods.

Pagination is a typical UI pattern, and now you know that you can easily build a paginated component with the help of useQuery and one of its options.

Another typical UI pattern is infinite scrolling. With the help of another useQuery variant called useInfiniteQuery, you learned how React...
