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 1: Understanding State and Getting to Know React Query
Part 2: Managing Server State with React Query


In this chapter, we learned about TanStack Query and how React Query fits into it. By now, you should be able to identify the primary way React Query makes server state management easier and how it uses queries and mutations.

You learned about QueryClient and QueryClientProvider and understood how they are fundamental to running React Query in your application. You also learned how you can customize your own QueryClient if you need to do so.

Finally, you got to meet the React Query Devtools and learned how to configure it in your project. Also, you are now able to load it into production for those special scenarios when you need to do some extra debugging.

In Chapter 4, Fetching Data with React Query, you will get to know your best friend for dealing with queries, the useQuery custom hook. You’ll understand how it works, how to use it, and how it can cache data. You will also learn the ways you can trigger query refetches and how to build dependent queries.
