React Native - Building Mobile Apps with JavaScript

By: Vladimir Novick

Overview of this book

<p>The emergence of React Native has made creating mobile apps in JavaScript easier for developers. This book introduces you to the React Native framework and the mobile apps development process. It starts with how React Native fits into the world of hybrid apps, and why it’s a popular framework. You’ll learn how React Native works under the hood--compiling JavaScript to Native code to bridge JavaScript and native apps. Also, you’ll learn how to write React Native components and use the ReactJS way of structuring your app. Understand how to use the industry standard Redux architecture as well as MobX--a newly emerging approach for state management--making your apps more robust and scalable.</p> <p>The mobile native world can be intimidating, with lots of platform-specific APIs. In this book, you’ll learn about the most important APIs with help of the real-world examples. You’ll also learn about the community packages that can help speed up your development. The book explains how to use these packages with JavaScript code, include native modules in your application, and write the modules yourself. Throughout the book, you will see examples of WhatsApp, Instagram, and YouTube apps and learn how to recreate them. You’ll also learn debugging and testing techniques, authentication, dealing with real data, and much more.</p> <p>At the end we will walk through design to production process of Twitter app clone and will explain application release process to App Store and Play Store</p>

Authenticating via social providers

Authenticating via social providers can be tricky in React Native since you basically need to communicate with a social provider SDK for the particular platform you are developing on. However, there are several projects that you can use to make it possible. While setup is not as straightforward as adding Firebase authentication, It's pretty much detailed and well documented:

https://github.com/fullstackreact/react-native-oauth

Another amazing project, which also enables you to use any of the provided Facebook APIs bundled in Facebook SDK is https://github.com/facebook/react-native-fbsdk.

The reason I won't cover the exact steps for authenticating with social providers is mostly because SDK changes, the projects I mentioned before have changed, and IOS and Android versions change, so it's important that I guide you to the projects...
