- Broaden your React expertise through mobile development with React Native

Book Description:

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 sixth edition reflects the current state of React, including coverage of React frameworks and 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 in place, 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.

Finally, a new chapter shows you how to use AI as a learning partner, covering practical workflows for AI-assisted debugging, evaluating AI-generated code, recognizing common pitfalls in React and React Native output, and writing code deliberately to deepen your understanding.

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.

What You Will Learn:

- 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 web apps using Material-UI

- Perform unit testing for your components with Vitest and mocking techniques

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

Who this book is for:

This book is for any JavaScript or TypeScript developer who wants to start learning how to use React and React Native for web and mobile app development.

No prior knowledge of React or React Native is required. However, a working knowledge of JavaScript is necessary to be able to follow along with the content covered.
