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>

Creating your application

Now, when we've set everything up, we can start creating React Native applications. At the beginning of this chapter when we've installed react native dependencies, we've installed the React Native command-line interface by running the following command:

npm install -g react-native-cli

We will use it to both run our application and to create it.

First of all, run the following in the terminal:

react-native init myFirstProject

The preceding command will create a new folder in your current directory and will create a React Native project inside of it. Let's open up this folder and briefly take a look at what we've got:

In the following chapters, we will cover all the inner bits of this project structure, but you can note that we have the __tests__ folder with two index JavaScript files for both Android and iOS.
