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.

Organizing code

There are many ways you can organize your code. Now, one thing we need to be aware of is choosing patterns that save you some time and make your code better in the long run. This section will discuss three different patterns that we can leverage together or independently to make our code more structured, readable, and organized. Here’s what we will discuss in this section:

  • Creating an API file
  • Leveraging query key factories
  • Creating a hooks folder

Creating an API file

Creating an API file to contain all my requests for a specific domain is a pattern that I follow.

In this file, I leverage my API client and create the functions responsible to make a request to a given route and return the request data.

This is particularly useful because it avoids repeating the logic for the same request in your code and focuses all the domain-specific requests in the same file.

For all the requests made in the scope of this book, I would prefer...
