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 with fetch

In this section, we will build an app containing a form that allows users to search and star GitHub repositories. The app will also have a header containing our name from GitHub. We will use the browser fetch function with React Query to interact with the GitHub GraphQL API. Let’s get started.

Creating the header

We will create the header for the app, which will contain our GitHub name. We will create a Header component containing this, which will be referenced from the App component. The Header component will use React Query to execute a function that gets our GitHub name calling the GitHub GraphQL API.

Creating a function to get viewer information

Carry out the following steps to create a function that makes a request to the GitHub GraphQL API to get details about the logged-in viewer:

  1. We will start by creating a folder for the API calls. Create an api folder in the src folder.
  2. Now, we will create a type that the function...
