Overview of this book

Reading, navigating, and debugging a large frontend codebase is a major issue faced by frontend developers. This book is designed to help web developers like you learn about ReactJS and TypeScript, both of which power large-scale apps for many organizations. This second edition of Learn React with TypeScript is updated, enhanced, and improved to cover new features of React 18 including hooks, state management libraries, and features of TypeScript 4. The book will enable you to create well-structured and reusable React components that are easy to read and maintain, leveraging modern design patterns. You’ll be able to ensure that all your components are type-safe, making the most of TypeScript features, including some advanced types. You’ll also learn how to manage complex states using Redux and how to interact with a GraphQL web API. Finally, you’ll discover how to write robust unit tests for React components using Jest. By the end of the book, you’ll be well-equipped to use both React and TypeScript.

Using React Query

React Query is a popular library for interacting with REST APIs. The key thing it does is manage the state surrounding REST API calls. One thing that it does that React Router doesn’t is that it maintains a cache of the fetched data, which improves the perceived performance of an app.

In this section, we will refactor the app to use React Query rather than React Router’s loader capability. We will then refactor the app again to use both React Query and React Router’s loader to get the best of both these worlds.

Installing React Query

Our first job is to install React Query, which we can do by running the following command in a terminal:

npm i @tanstack/react-query

This library includes TypeScript types, so no additional package is required to be installed.

Adding the React Query provider

React Query requires a provider component in the component tree above the components that need access to the data it manages. Eventually...
