React Native Share API to Share TextInput message

React Native Share

React Native Share API to Share TextInput message includes the React Native Share component which is used to share any content. We usually add a share button in our app to share something with other users either using any social media or any other medium.  Here is an example of React Native Share API to Share TextInput messages from our App.

You can also see:

1. Share Facebook Post with URL from React Native App
2. Send WhatsApp Message from React Native App
3. Tweet on Twitter with URL from React Native App
4. Send Text SMS on Button Click in React Native

To Import Share API in Code

import {Share} from 'react-native'

Use of Share API

Share.share({
  message: this.state.inputValue.toString(),
})
.then(result => console.log(result))
.catch(errorMsg => console.log(errorMsg));

In this example, We will share the input of a TextInput on a button click using the Share API provided by React Native. It will open different platforms where you can share content like Mail, Facebook, Twitter, Whatsapp, etc. 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

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

App.js

// React Native Share API to Share TextInput message
// https://aboutreact.com/react-native-share-api-to-share-text-input-message/

// 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,
  Share,
} from 'react-native';

const App = () => {
  const [inputValue, setInputValue] = useState('');

  const shareMessage = () => {
    //Here is the Share API
    Share.share({
      message: inputValue.toString(),
    })
      //after successful share return result
      .then((result) => console.log(result))
      //If any thing goes wrong it comes here
      .catch((errorMsg) => console.log(errorMsg));
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text style={styles.titleText}>
          React Native Share API to Share TextInput message
        </Text>
        <Text style={styles.titleTextsmall}>
          Enter Text to Share
        </Text>
        <TextInput
          value={inputValue}
          onChangeText={
            (inputValue) => setInputValue(inputValue)
          }
          placeholder={'Enter Text to Share'}
          style={styles.textInput}
        />
        <TouchableOpacity
          activeOpacity={0.7}
          style={styles.buttonStyle}
          onPress={shareMessage}>
          <Text style={styles.buttonTextStyle}>
            Share Input Text
          </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',
  },
  titleTextsmall: {
    marginVertical: 8,
    fontSize: 16,
  },
  buttonStyle: {
    justifyContent: 'center',
    marginTop: 15,
    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
