Preface

Over the years, React and React Native have proven themselves among JavaScript developers as popular choices for a comprehensive and practical guide to the React ecosystem. This fifth edition comes with the latest features, enhancements, and fixes of React, while also being compatible with React Native. It includes new chapters covering critical features and concepts in modern cross-platform app development with React and TypeScript.

From the basics of React to popular features such as Hooks, server rendering, and unit testing, this definitive guide will help you become a professional React developer in a step-by-step manner.

You’ll begin by learning about the essential building blocks of React components. Next, you’ll learn how to improve the stability of your components using TypeScript. As you advance through the chapters, you’ll work with higher-level functionalities in application development and then put your knowledge to work by developing user interface components for the web and native platforms.

By the end of this book, you’ll be able to build React applications for the web and React Native applications for multiple platforms: web, mobile, and desktop: with confidence.

To get the most out of this book

This book assumes you have a basic understanding of the JavaScript programming language. It also assumes that you’ll be following along with the examples, which require a command-line terminal, a code editor, and a web browser. You’ll learn how to set up a React project in Chapter 1, Why React?.

The requirements for learning React Native are the same as for React development, but to run an app on a real device, you will need an Android or iOS smartphone. In order to run iOS apps in the simulator, you will need a Mac computer. To work with Android simulator, you can use any kind of PC.
