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.

Understanding common challenges with server state

By now, you have probably figured out that the server state comes with quite its fair share of challenges. These challenges made React Query stand out even more when it came out because it solved them in such a simple way for developers that it seemed too good to be true.

Now, what are these challenges, and why are they so complex to solve most of the time?

In this section, we will see all the common challenges that we have with the server state and understand a bit of the hard work we had to do as developers to solve them ourselves before we had React Query.


This is probably one of the hardest challenges we face in server state management.

To improve your page performance and make your site more responsive, very often, you will need to cache your data. This means being able to reuse data that you previously fetched to avoid refetching it from the server once again.

Now, you might be thinking that this sounds...
