Welcome to your big-picture guide to the React ecosystem.

If you’re new to React and looking to become a professional React developer, this book is for you. This updated fifth edition reflects the current state of React, including React framework coverage as well as TypeScript.

Part 1 introduces you to React. You’ll discover JSX syntax, hooks, functional components, and event handling, learn techniques to fetch data from a server, and tackle the tricky problem of state management. Once you’re comfortable with writing React in JavaScript, you’ll pick up TypeScript development in later chapters.

Part 2 transitions you into React Native for mobile development. React Native goes hand-in-hand with React. With your React knowledge behind you, you’ll appreciate where and how React Native differs as you write shared components for Android and iOS apps. You’ll learn how to build responsive layouts, use animations, and implement geolocation.

By the end of this book, you’ll have a big-picture view of React and React Native and be able to build applications with both.

- Explore React architecture, component properties, state, and context

- Work with React Hooks for handling functions and components

- Fetch data from a server using the Fetch API, GraphQL, and WebSockets

- Dive into internal and external state management strategies

- Build robust user interfaces (UIs) for mobile and desktop apps using Material-UI

- Perform unit testing for your components with Vitest and mocking

- Manage app performance with server-side rendering, lazy components, and Suspense

This unique book introduces both React and React Native, giving you a big picture view of the React ecosystem.

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.
