React Native

Master the latest tools, architecture, and best practices for building high-performance mobile apps with React Native

• Understand how React Native's new architecture (Fabric, TurboModules, Hermes) improves performance and scalability.

• Learn to set up your development environment, structure projects, and build reusable UI components.

• Integrate navigation, animations, networking, authentication, and real-time data with modern tools like React Navigation, Zustand, and Firebase.

• Optimize performance, test your apps, and prepare them for deployment to both iOS and Android app stores.

React Native continues to be one of the most powerful frameworks for creating real, native mobile apps using JavaScript and React. In 2025, the framework is faster, more stable, and better integrated with modern developer tools than ever before - making it a top choice for building production-ready cross-platform apps.

This comprehensive guide walks you through every stage of building an app with React Native - from setting up your environment to launching on the App Store and Google Play. You'll learn how to use the latest architecture for faster UI rendering and improved module loading, master core components and APIs, implement navigation patterns, and manage both local and global state.

You'll also discover how to handle forms and validation, fetch and synchronize data with APIs, integrate Firebase for authentication and real-time features, and leverage device capabilities like the camera, GPS, and sensors. Finally, you'll learn how to polish your UI with animations, test your application, and deploy it with confidence.

By the end of this book, you'll have all the knowledge you need to design, build, and maintain professional-grade mobile apps using React Native's latest tools and best practices.

• Get up to speed with React Native's core components, hooks, and APIs.

• Set up projects with Expo CLI or the bare React Native CLI.

• Use React Navigation to implement stacks, tabs, and drawers.

• Manage state effectively with hooks, Context API, Zustand, or Redux Toolkit.

• Work with APIs, handle asynchronous data, and manage server state.

• Add real-time features and media handling with Firebase.

• Access native device capabilities, sensors, and permissions.

• Test your applications with Jest, Testing Library, and Detox.

• Optimize, package, and deploy apps to iOS and Android stores.

This book is for JavaScript and React developers who want to take their skills into mobile development with React Native. Whether you're building your first app or already have some experience, you'll benefit from the modern best practices and detailed, step-by-step examples provided. Familiarity with React is helpful but not required.
