Overview of this book

If you are a developer looking to create mobile applications with maximized code reusability and minimized cost, React Native is what you need. With this practical guide, you’ll be able to build attractive UIs, tackle common problems in mobile development, and achieve improved performance in mobile environments. This book starts by covering the common techniques for React Native customization and helps you set up your development platforms. Over the course of the book, you’ll work through a wide variety of recipes that help you create, style, and animate your apps with built-in React Native and custom third-party components. You’ll also develop real-world browser-based authentication, build a fully functional audio player, and integrate Google Maps in your apps. This book will help you explore different strategies for working with data, including leveraging the popular Redux library and optimizing your app’s dataflow. You’ll also learn how to write native device functionality for new and existing React Native projects and how app deployment works. By the end of this book, you'll be equipped with tips and tricks to write efficient code and have the skills to build full iOS and Android applications using React Native.

Setting Up Your Environment

The React Native ecosystem has evolved quite a bit since the first edition. The open source tool Expo.io, in particular, has streamlined both the project initialization and development phases, making working in React Native even more of a pleasure than it already was in version 0.36.

With the Expo workflow, you'll be able to build native iOS and Android applications using only JavaScript, work in the iOS simulator and Android emulator with live reload, and effortlessly test your app on any real-world device via Expo's app. Until you need access to native code (say, to integrate with legacy native code from a separate code base), you can develop your application entirely in JavaScript without ever needing to use Xcode or Android Studio. If your project ever evolves into an app that must support native code, Expo provides the ability to eject your project, which changes your app into native code for use in Xcode and Android Studio. For more information on ejecting your Expo project, please see Chapter 10, App Workflow and Third-Party Plugins.

Expo is an awesome way to build fully featured apps for Android and iOS devices, without ever having to deal with native code. Let's get started!

We will cover the following topics in this chapter:

  • Installing dependencies
  • Initializing your first application
  • Running your application in a simulator/emulator
  • Running your application on a real device
