Setting up the folder structure

Let's initialize a React Native project using React Native's CLI. The project will be named imageShare and will be available for iOS and Android devices:

react-native init --version="0.44.0" imageShare

In order to use some packages in this app, we will be using a specific version of React Native (0.44.0).

We will be using Redux for our app, so we will create a folder structure in which we can accommodate our reducers, actions, components, screens, and api calls:

Moreover, we have added logo.png in the img folder. For the rest, we have a very standard React Native project. The entry point will be index.ios.js for iOS and index.android.js for Android:

/*** index.ios.js and index.android.js ***/ 

import { AppRegistry } from 'react-native';
import App from './src/main';

AppRegistry.registerComponent('imageShare', () => App);

We have the same implementation for both files as we want to use src/main.js as the common entry point for both platforms.
