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.

Interacting with RESTful APIs

In this chapter, we will build a page that lists blog posts fetched from a REST API, as well as also a form to submit blog posts to the REST API. Through this, we will learn about various approaches to interacting with a REST API from a React component.

The first approach will be using React’s useEffect hook with the browser’s fetch function. As part of this process, we learn how to use a type assertion function to strongly type the data from a REST API. We will then use the data loading capability of React Router and experience its benefits. After that, we will move on to use a popular library called React Query and experience its benefits, before using React Query and React Router together to get the best of both these libraries.

So, in this chapter, we’ll cover the following topics:

  • Getting set up
  • Using the effect hook with fetch
  • Posting data with fetch
  • Using React Router
  • Using React Query
  • Using...
