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.

Summary

We started the chapter by creating a React and TypeScript project with the help of webpack and Babel. Lots of steps were involved and we only set up a fraction of what we would need for a real project. For example, we have not set up the ability to produce an optimized bundle for production.

We moved on to use Create React App for creating a React and TypeScript project. We saw how this approach is a much faster and more thorough way of creating a project. Then, we used ESLint for linting and Prettier for automatic code formatting. As a result of that exercise, we now understand how TypeScript, ESLint, and Prettier can be used together to create a high-quality React and TypeScript project environment.

In the final section, we learned how to create React components with strongly typed props and states. We experienced how this helps to catch problems quickly. We also played with React’s DevTools, which allows a React component tree to be inspected and the performance...
