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.

Adding React Query Devtools

When debugging our applications, we often find ourselves thinking how amazing it would be to have a way to visualize what is happening inside our application. Well, with React Query, you don’t have to worry because it has its own developer tools, or devtools.

React Query Devtools allows you to see and understand the current state of all your queries and mutations. This will save you a lot of time debugging and avoid polluting all your code with unnecessary log functions, even if temporarily.

Depending on the type of project, you can install React Query Devtools in several ways:

  • If you are running npm in your project, run the following command:
    npm i @tanstack/react-query-devtools
  • If you are using Yarn, run the following command:
    yarn add @tanstack/react-query-devtools
  • If you are using pnpm, run the following command:
    pnpm add @tanstack/react-query-devtools

Now, you should have React Query Devtools installed in your application...
