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.

Performing Data Mutations with React Query

When building applications, you won’t always need to fetch data. Sometimes, you will want to create, update, or delete it. When doing these actions, your server state will have to change.

React Query allows you to change your server state by using mutations. To perform mutations, you can leverage another of React Query’s custom hooks, called useMutation.

In this chapter, you will be introduced to the useMutation hook and understand how React Query allows you to create, update, and delete your server state. Similar to Chapter 4, during this process, you will learn about all the defaults used in your mutations. You will also be introduced to some options you can use to improve your useMutation experience.

Once you are familiar with useMutation, you will get to know how you can leverage some of its options to perform some side-effect patterns, such as manually updating your data or forcing a query to update after performing...
