By: Carl Rippon

Overview of this book

React today is one of the most preferred choices for frontend development. Using React with TypeScript enhances development experience and offers a powerful combination to develop high performing web apps. In this book, you’ll learn how to create well structured and reusable react components that are easy to read and maintain by leveraging modern web development techniques. We will start with learning core TypeScript programming concepts before moving on to building reusable React components. You'll learn how to ensure all your components are type-safe by leveraging TypeScript's capabilities, including the latest on Project references, Tuples in rest parameters, and much more. You'll then be introduced to core features of React such as React Router, managing state with Redux and applying logic in lifecycle methods. Further on, you'll discover the latest features of React such as hooks and suspense which will enable you to create powerful function-based components. You'll get to grips with GraphQL web API using Apollo client to make your app more interactive. Finally, you'll learn how to write robust unit tests for React components using Jest. By the end of the book, you'll be well versed with all you need to develop fully featured web apps with React and TypeScript.

Interacting with RESTful APIs

Interacting with RESTful APIs is a very common task we need to do when building an app, and it always results in us having to write asynchronous code. So, to begin with in this chapter, we'll have a detailed look at asynchronous code in general.

There are many libraries that we can use to help us interact with REST APIs. In this chapter, we'll look at both a native browser function and a popular open source library for interacting with REST APIs. We'll discover the additional features that the open source library has over the native function. We will also look at how we can interact with a REST API in both React class and function-based components.

In this chapter, we'll learn the following topics:

  • Writing asynchronous code
  • Using fetch
  • Using axios with class components
  • Using axios with function components
