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.

Server State versus Client State

Global state is the most common way we look at state. It is the state that is shared globally in our application by one or more components.

What we don’t often know is that in our day-to-day development, our global state ends up being split between the state that persists outside of our application and the state that only exists within our application. The first type of state is called server state, while the second one is called client state. Both of these types of states have their specific challenges and require different tools to help manage them.

In this chapter, we will understand why we refer mostly to our state as global state and why we should adjust our mental models to include client and server states instead.

We’ll also review what each type of state is responsible for and how to differentiate them in an application and understand the challenges that led to the creation of React Query.
