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 fully understood the concept of global state. By now, you should be able to understand why often our state is called global state and how much harder it can be to maintain it if we don’t split it.

You learned how to split your state into client and server states and understand how each of these types of states is important for your application and how you can identify them in your code.

Finally, you were familiarized with the challenges that server state can bring to your application and understood that if you were to address them all by yourself, then your code complexity would increase significantly and you’d probably lose some much-needed sleeping hours.

In Chapter 3, React Query – Introducing, Installing, and Configuring It, you will start getting hands-on with React Query. You will understand what it is and how it saves you from all the headaches that server state brings to your applications. You will learn how to install...
