Getting started

If you are using react-native >= 0.60.0 please use react-native-share >= 2.0.0

Automatic Way

yarn add react-native-share

or if you’re using npm

npm install react-native-share --save

Requirements:

  1. Xcode 11 or higher
  2. iOS 13 SDK or higher

Important:

Linking is not needed anymore. react-native@0.60.0+ supports dependencies auto linking. For iOS you also need additional step to install auto linked Pods:

npx pod-install

If you are using react-native <= 0.59.10 please use react-native-share <= 1.2.1:

If you are having any problems with this library, or need to use >= 2.0.0 please refer to: jetifier.

After installing jetifier, runs a npx jetify -r and test if this works by running a react-native run-android.

Automatic Way

yarn add react-native-share
react-native link react-native-share # not needed for react-native >= 0.60.0

or if you’re using npm

npm install react-native-share --save
react-native link react-native-share # not needed for react-native >= 0.60.0

We recommend using the releases from npm, however you can use the master branch if you need any feature that is not available on NPM. By doing this you will be able to use unreleased features, but the module may be less stable. yarn:

yarn add react-native-share@git+https://git@github.com/react-native-community/react-native-share.git

LSApplicationQueriesSchemes on iOS

Remember to add instagram, facebook or whatever queries schemes you need to LSApplicationQueriesSchemes field in your Info.plist. This is required to share content directly to other apps like Instagram, Facebook etc. Values for queries schemes can be found in Social field of RNShare class.

Manual install

iOS Install

  1. yarn add react-native-share

  2. In XCode, in the project navigator, right click LibrariesAdd Files to [your project's name]

  3. Go to node_modulesreact-native-shareios and add RNShare.xcodeproj

  4. In XCode, in the project navigator, select your project. Add libRNShare.a to your project’s Build PhasesLink Binary With Libraries

  5. In XCode, in the project navigator, select your project. Add Social.framework and MessageUI.framework to your project’s GeneralLinked Frameworks and Libraries

  6. In iOS 9 or higher, you should add app list that you will share. If you want to share Whatsapp and Mailto, you should write LSApplicationQueriesSchemes in info.plist

    <key>LSApplicationQueriesSchemes</key>
    <array>
      <string>whatsapp</string>
      <string>mailto</string>
    </array>
    
  7. (Optional) Also following lines allows users to save photos, add them in info.plist

    <key>NSPhotoLibraryAddUsageDescription</key>
    <string>$(PRODUCT_NAME) wants to save photos</string>
    
  8. Run your project (Cmd+R)

iOS Install (using Pods)

If you wish, you can use cocopoads to use react-native-share.

You just need to add to your Podfile the react-native-share dependency.

  # React-Native-Share pod
  pod 'RNShare', :path => '../node_modules/react-native-share'

After that, just run a pod install or pod udpate to get up and running with react-native-share.

Then run a react-native link react-native-share, and doing the steps 6 and 7.

You can also see our example to see how you need to setup your podfile.

Btw, We also recommend reading this amazing article about how pods and rn work together. =D

Android Install

  1. yarn add react-native-share

Returns a promise that fulfills or rejects as soon as user successfully open the share action sheet or cancelled/failed to do so. As a result you might need to further handle the rejection while necessary. e.g.

*For share multiple files, you must using option urls instead of url to share multiple files/images/docs. Example could be found in Example folder

  Share.open(options)
    .then((res) => { console.log(res) })
    .catch((err) => { err && console.log(err); });

isPackageInstalled() (in Android)

It’s a method that checks if an app (package) is installed on Android. It returns a promise with isInstalled. e.g.

Checking if Instagram is installed on Android.

Static Values for social

These can be assessed using Share.Social property For eg.

import Share from 'react-native-share';

const shareOptions = {
    title: 'Share via',
    message: 'some message',
    url: 'some share url',
    social: Share.Social.WHATSAPP,
    whatsAppNumber: "9199999999",  // country code + phone number
    filename: 'test' , // only for base64 file in Android
};
Share.shareSingle(shareOptions);

Troubleshooting

Language Support (iOS)

On iOS, share component reads language value from CFBundleDevelopmentRegion at Info.plist file. By changing CFBundleDevelopmentRegion value you can change default language for component.

<key>CFBundleDevelopmentRegion</key>
<string>en</string>

For supporting multi language, you can add CFBundleAllowMixedLocalizations key to Info.plist.

<key>CFBundleAllowMixedLocalizations</key>
<string>true</string>

LinkPresentation.h file not found

  1. Check iOS SDK version running this command: xcodebuild -showsdks
  2. If your SDK is 12 or lower you need to update to Xcode 11 with iOS SDK 13
  3. Build the app with Xcode 11 and everything works ok

Share Remote PDF File with Gmail & WhatsApp (iOS)

When sharing a pdf file with base64, there are two current problems.

  1. On WhatsApp base64 wont be recognized => nothing to share
  2. In the GmailApp the file extension is wrong (.dat).

Therefore we use this “workaround” in order to handle pdf sharing for iOS Apps to mentioned Apps

  1. Install react-native-fetch-blob
  2. Set a specific path in the RNFetchBlob configurations
  3. Download the PDF file to temp device storage
  4. Share the response’s path() of the donwloaded file directly

Code:

static sharePDFWithIOS(fileUrl, type) {
  let filePath = null;
  let file_url_length = fileUrl.length;
  const configOptions = {
    fileCache: true,
    path:
      DIRS.DocumentDir + (type === 'application/pdf' ? '/SomeFileName.pdf' : '/SomeFileName.png') // no difference when using jpeg / jpg / png /
  };
  RNFetchBlob.config(configOptions)
    .fetch('GET', fileUrl)
    .then(async resp => {
      filePath = resp.path();
      let options = {
        type: type,
        url: filePath // (Platform.OS === 'android' ? 'file://' + filePath)
      };
      await Share.open(options);
      // remove the image or pdf from device's storage
      await RNFS.unlink(filePath);
    });
}

Nothing to do on Android. You can share the pdf file with base64

static sharePDFWithAndroid(fileUrl, type) {
  let filePath = null;
  let file_url_length = fileUrl.length;
  const configOptions = { fileCache: true };
  RNFetchBlob.config(configOptions)
    .fetch('GET', fileUrl)
    .then(resp => {
      filePath = resp.path();
      return resp.readFile('base64');
    })
    .then(async base64Data => {
      base64Data = `data:${type};base64,` + base64Data;
      await Share.open({ url: base64Data });
      // remove the image or pdf from device's storage
      await RNFS.unlink(filePath);
    });
}

Static Values for Instagram Stories

These can be assessed using Share.Social property For eg.

import Share from 'react-native-share';

const shareOptions = {
    method: Share.InstagramStories.SHARE_BACKGROUND_AND_STICKER_IMAGE,
    backgroundImage: 'http://urlto.png',
    stickerImage: 'data:image/png;base64,<imageInBase64>', //or you can use "data:" link
    backgroundBottomColor: '#fefefe',
    backgroundTopColor: '#906df4',
    attributionURL: 'http://deep-link-to-app', //in beta
    social: Share.Social.INSTAGRAM_STORIES
};
Share.shareSingle(shareOptions);

const shareOptions = {
    method: Share.FacebookStories.SHARE_BACKGROUND_AND_STICKER_IMAGE,
    backgroundImage: 'http://urlto.png', // url or an base64 string
    stickerImage: 'data:image/png;base64,<imageInBase64>', //or you can use "data:" url
    backgroundBottomColor: '#fefefe',
    backgroundTopColor: '#906df4',
    attributionURL: 'http://deep-link-to-app', //in beta
    appId: '219376304', //facebook appId

Adding your implementation of FileProvider

Android guide.

  • applicationId should be defined in the defaultConfig section in your android/app/build.gradle:

  • File: android/app/build.gradle

    defaultConfig {
        applicationId "com.yourcompany.yourappname"
        ...
    }
    
    
  • Add this <provider> section to your AndroidManifest.xml

    File: AndroidManifest.xml

    <application>
        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:grantUriPermissions="true"
            android:exported="false">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/filepaths" />
        </provider>
    </application>
    
  • Create a filepaths.xml under this directory: android/app/src/main/res/xml.

    In this file, add the following contents:

    File: android/app/src/main/res/xml/filepaths.xml

    <?xml version="1.0" encoding="utf-8"?>
    <paths xmlns:android="http://schemas.android.com/apk/res/android">
      <external-path name="myexternalimages" path="Download/" />
    </paths>
    
  • Edit your MainApplication.java class to add implements ShareApplication and getFileProviderAuthority

  • The getFileProviderAuthority function returns the android:authorities value added in the AndroidManifest.xml file

  • applicationId is defined in the defaultConfig section of your android/app/build.gradle and referenced using BuildConfig.APPLICATION_ID

    import cl.json.ShareApplication
    public class MainApplication extends Application implements ShareApplication, ReactApplication {
    
         @Override
         public String getFileProviderAuthority() {
                return BuildConfig.APPLICATION_ID + ".provider";
         }
    
         // ...Your own code
    
    }
    

Mocking with Jest

  • To mock when using Jest. Add the below line on your __mock__ directory.
jest.mock('react-native-share', () => ({
  default: jest.fn(),
}));
