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

When dealing with server state, many challenges are attached to how we read from it. From caching to pagination, we will understand how the React Query custom hook called useQuery makes this work while giving an amazing combined developer and user experience.

As well as the challenges of how we read our server state, creating, updating, and deleting it brings about another set of challenges. Luckily, React Query has another custom hook that comes to the rescue called useMutation.

After understanding the pillars of React Query, you might be wondering whether popular server-side frameworks such as Next.js and Remix allow you to use React Query. Spoiler alert – they do, and you will learn how here.

To wrap up and make sure that you will be able to sleep well at night, you will learn a set of recipes you can use to test your React Query, using components and custom hooks by levering Mock Service Worker and the React Testing...
