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>

Using the Twitter API to work with real data

Now, it's about time we connect our app to the actual Twitter API, but before we do that, we need to eject from CRNA. Connection to Twitter API will be done by the npm package with native modules dependencies, and we will need to link them properly:

npm run eject

Now, the app will fail if you run it, because as I mentioned earlier, react-native-elements has a dependency on react-native-vector-icons. When we worked inside an environment with expokit installed, all was good, but as soon as we ran eject into react native app, we need to install and link this dependency.

So, let's run this command:

npm i -S react-native-vector-icons

And then link vector icons properly by running:

react-native link

Now we will be able to use icons in the same way we used them earlier.

In our next step, we will switch part of the mocked state to...
