Tweet on Twitter with URL from React Native App

Tweet on Twitter from React Native App

This is an example of Tweet on Twitter with URL from React Native App. Adding Twitter share is a cool idea nowadays as it is trending and provides an attractive feature in your application. One-click tweet provides a great user experience to share your application’s content on Twitter.

If you have seen our last post on React Native Share API to Share TextInput message you will see it provides all the possible solutions available in the device to share the input text but what if you just want to share the content on Twitter then this example will help you to share the content on Twitter.

In this example, you will see

Content sharing (Tweet content)
Share the URL with the content
Mention any twitter handler

We are going to use the deep linking property which will open Twitter App if it is available else it will open twitter in the browser. We are using Linking component provided by the React Native core library.

To Tweet on Twitter with URL from React Native App

const tweetNow = () => {
  let twitterParameters = [];
  if (twitterShareURL)
    twitterParameters.push('url=' + encodeURI(twitterShareURL));
  if (tweetContent)
    twitterParameters.push('text=' + encodeURI(tweetContent));
  if (twitterViaAccount)
    twitterParameters.push('via=' + encodeURI(twitterViaAccount));
  const url =
    'https://twitter.com/intent/tweet?'
    + twitterParameters.join('&');
  Linking.openURL(url)
    .then((data) => {
      alert('Twitter Opened');
    })
    .catch(() => {
      alert('Something went wrong');
    });
};

In this example, we are taking the tweet content, URL, and twitter handle (to mention) as input from the user, and then we will tweet the content from our React native app. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react native command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Code to Tweet on Twitter

Open App.js in any code editor and replace the code with the following code

App.js

// Tweet on Twitter with URL from React Native App
// https://aboutreact.com/react-native-twitter-share/

// import React in our code
import React, {useState} from 'react';

// import all the components we are going to use
import {
  SafeAreaView,
  StyleSheet,
  View,
  Text,
  TouchableOpacity,
  TextInput,
  Linking,
} from 'react-native';

const App = () => {
  const [twitterShareURL, setTwitterShareURL] = useState(
    'https://aboutreact.com',
  );
  const [tweetContent, setTweetContent] = useState(
    'Hello Guys, This is a testing of twitter share example',
  );
  const [
    twitterViaAccount,
    setTwitterViaAccount
  ] = useState('AboutReact');

  const tweetNow = () => {
    let twitterParameters = [];
    if (twitterShareURL)
      twitterParameters.push('url=' + encodeURI(twitterShareURL));
    if (tweetContent)
      twitterParameters.push('text=' + encodeURI(tweetContent));
    if (twitterViaAccount)
      twitterParameters.push('via=' + encodeURI(twitterViaAccount));
    const url =
      'https://twitter.com/intent/tweet?'
      + twitterParameters.join('&');
    Linking.openURL(url)
      .then((data) => {
        alert('Twitter Opened');
      })
      .catch(() => {
        alert('Something went wrong');
      });
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text style={styles.titleText}>
          Tweet on Twitter with URL from React Native App
        </Text>
        <Text style={{marginTop: 20}}>
          Enter Tweet Content
        </Text>
        <TextInput
          value={tweetContent}
          onChangeText={
            (tweetContent) => setTweetContent(tweetContent)
          }
          placeholder={'Enter Tweet Content'}
          style={styles.textInput}
        />
        <Text style={{marginTop: 20}}>
          Enter URL to Share
          </Text>
        <TextInput
          value={twitterShareURL}
          onChangeText={(twitterShareURL) =>
            setTwitterShareURL(twitterShareURL)
          }
          placeholder={'Enter URL to Share'}
          style={styles.textInput}
        />
        <Text style={{marginTop: 20}}>
          Enter Via Account
        </Text>
        <TextInput
          value={twitterViaAccount}
          onChangeText={(twitterViaAccount) =>
            setTwitterViaAccount(twitterViaAccount)
          }
          placeholder={'Enter Via Account'}
          style={styles.textInput}
        />
        <TouchableOpacity
          activeOpacity={0.7}
          style={styles.buttonStyle}
          onPress={tweetNow}>
          <Text style={styles.buttonTextStyle}>
            Tweet Now
          </Text>
        </TouchableOpacity>
      </View>
    </SafeAreaView>
  );
};

export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
    padding: 10,
    textAlign: 'center',
  },
  titleText: {
    fontSize: 22,
    textAlign: 'center',
    fontWeight: 'bold',
  },
  buttonStyle: {
    justifyContent: 'center',
    marginTop: 15,
    width: '50%',
    padding: 10,
    backgroundColor: '#8ad24e',
    marginRight: 2,
    marginLeft: 2,
  },
  buttonTextStyle: {
    color: '#fff',
    textAlign: 'center',
  },
  textInput: {
    height: 40,
    borderColor: 'gray',
    borderWidth: 1,
    width: '100%',
    paddingHorizontal: 10,
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command:

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device:

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
