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.

Creating a React and TypeScript component

In Chapter 1, Introducing React, we built an alert component using React. In this section, we will use TypeScript to make the component strongly typed and experience the benefits. We start by adding a type to the alert component’s props and then experiment with defining a type for its state. After completing the alert component, we will inspect the component using React’s DevTools.

Adding a props type

We will continue using the React and TypeScript project created in the last section with Create React App. Take the following steps to add a strongly typed version of the alert component:

  1. Open the project in Visual Studio Code if it isn’t already open. Make sure you open the project in the app name folder so that package.json is at the root.
  2. Create a new file in the src folder called Alert.tsx. Paste in the JavaScript version of the alert component, which can be found on GitHub at https://github.com/PacktPublishing...
