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.

Boosting the performance of our app

The reason for React Native's existence is building native apps with JavaScript. This is different than similar frameworks such as Ionic or Cordova hybrid applications, which wrap a web application written in JavaScript and attempt to emulate native app behavior. Those web applications only have access to native APIs for performing processing, but cannot render native views inside their apps. This is one major benefit to React Native apps, thus making them inherently faster than hybrid apps. Since it's so much more performant out of the box, we generally do not have to worry about overall performance as much as we would with a hybrid web app. Still, with a little extra effort, a slight improvement in performance might be achievable. This recipe will provide some quick wins that we can use to build faster React Native apps.
