Build WordPress App with React Native #9: a simple share

This series intends to show how I build app to serve content from my WordPress blog by using react native. Since, my blog is talking about react-native, the series and the articles are interconnected. We will learn how to set-up many packages that make our lives comfortable and learn how to deal with WordPress APIs. Here, the most prominent features talked about in the book are the dark theme , offline mode, infinite scroll and many more. You can discover much more in this series.this inspiration to do this tutorial series came from the React Native mobile Templates

Here, we are going to add the share button and implement its feature as well. The feature makes the article sharable to the social media accounts when pressing the share button. For that, we are going to make use of the Share component from the react-native package.

Hence, we need to import Share and TouchableOpacity components from the
react-native package as shown in the code snippet below:

    import {
      View,
      ScrollView,
      ActivityIndicator,
      Dimensions,
      Share,
      TouchableOpacity,
    } from 'react-native';

Then, we need to define a `onShare` function as shown in the code snippet below:

    onShare = async (title, uri) => {
        Share.share({
          title: title,
          url: uri,
        });
      };

Here, we have used the share method from the Share component and provided
the title and url of the article as parameters.

Now, we need to add the share button to the right side of the author section.
For that, we need to use the code from the following code snippet:

    <List.Item
     title={`${post[0]._embedded.author[0].name}`}
     description={`${post[0]._embedded.author[0].description}`}
      right={props => {
       return (
         <TouchableOpacity
           onPress={() =>
             this.onShare(post[0].title.rendered, post[0].link)
           }>
           <FontAwesome name="share" size={30} />
         </TouchableOpacity>
       );
     }}

Here, we have used the right prop of the List component in order to return the template for the share button. The share button template contains the TouchableOpacity component which wraps the FontAwesome component with the share icon. The onShare function is called in the onPress event of the TouchableOpacity component. We also need to remember to import the FontAwesome icon bundle from the vector-icons package:

import FontAwesome from 'react-native-vector-icons/FontAwesome';

Hence, we will get the following result in the emulators:

As we can see, when we click on the share button, a modal appears from the button which enables us to share the article with social accounts.

Summary

In this chapter, we learned how to make use of Share component from the react-native package to implement the share button. Then, we also learned how to configure the Share component in order for the sharing screen to pop up in the screen. We made use of share() function provided by the Share component in order to display the sharing screen pop up. This allows us to share the article to the social accounts. Finally, we implemented the share button using the vector icon as well.
