React Native FBSDK

React Native FBSDK is a wrapper around the iOS Facebook SDK and Android Facebook SDK, allowing for Facebook integration in React Native apps. Access to native components, from login to sharing, is provided entirely through documented JavaScript modules so you don't have to call a single native function directly.

Functionality is provided through one single npm package so you can use it for both platforms without downloading any extra packages. Follow this guide to use react-native-fbsdk in your react-native app. You can also visit https://developers.facebook.com/docs/react-native for tutorials and reference documentation.

Installation

You need to install the sdk with npm and configure native Android/iOS project in the react native project.

1. Create React Native project

First create a React Native project:

react-native init YourApp

2. Install JavaScript packages

Install and link the react-native-fbsdk package:

react-native install react-native-fbsdk
react-native link react-native-fbsdk

3. Configure native projects

3.1 Android project

Assuming you have Android Studio installed, open the project with Android Studio.

If your react-native version is below 0.29.0

Go to MainActivity.java under app/src/main/java/com/<project name>/ to complete setup. Note that packages must be imported to use.

Add an instance variable of type CallbackManager in class.

import android.content.Intent;     // <--- import
import android.os.Bundle;

import com.facebook.CallbackManager;
import com.facebook.FacebookSdk;
import com.facebook.reactnative.androidsdk.FBSDKPackage;

public class MainActivity extends ReactActivity {
    CallbackManager mCallbackManager;
    //...

Register sdk package in method getPackages().

@Override
protected List<ReactPackage> getPackages() {
    mCallbackManager = new CallbackManager.Factory().create();
    ReactPackage packages[] = new ReactPackage[]{
        new MainReactPackage(),
        new FBSDKPackage(mCallbackManager),
    };
    return Arrays.<ReactPackage>asList(packages);
}

Override onActivityResult().

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    mCallbackManager.onActivityResult(requestCode, resultCode, data);
}

Before you can run the project, follow the Getting Started Guide for Facebook Android SDK to set up a Facebook app. You can skip the build.gradle changes since that's taken care of by the rnpm link step above, but make sure you follow the rest of the steps such as calling FacebookSdk.sdkInitialize and updating strings.xml and AndroidManifest.xml. Note that react-native project doesn't have the Application class, so you'll need to create an implementation of the Application class yourself.

If your react-native version is 0.29 or above

Go to MainApplication.java and MainActivity.java under app/src/main/java/com/<project name>/ to complete setup.

In MainApplication.java,

Add an instance variable of type CallbackManager and its getter.

import com.facebook.CallbackManager;
import com.facebook.FacebookSdk;
import com.facebook.reactnative.androidsdk.FBSDKPackage;
import com.facebook.appevents.AppEventsLogger;
...

public class MainApplication extends Application implements ReactApplication {

  private static CallbackManager mCallbackManager = CallbackManager.Factory.create();

  protected static CallbackManager getCallbackManager() {
    return mCallbackManager;
  }
    //...

Override onCreate() method

@Override
public void onCreate() {
  super.onCreate();
  FacebookSdk.sdkInitialize(getApplicationContext());
  // If you want to use AppEventsLogger to log events.
  AppEventsLogger.activateApp(this);
}

Register sdk package in method getPackages().

private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    @Override
    public boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new FBSDKPackage(mCallbackManager)
      );
    }
};

In MainActivity.java

Override onActivityResult() method

import android.content.Intent;

public class MainActivity extends ReactActivity {

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        MainApplication.getCallbackManager().onActivityResult(requestCode, resultCode, data);
    }
    //...

Before you can run the project, follow the Getting Started Guide for Facebook Android SDK to set up a Facebook app. You can skip the build.gradle changes since that's taken care of by the rnpm link step above, and the step of calling FacebookSdk.sdkInitialize. But make sure you follow the rest of the steps such as updating strings.xml and AndroidManifest.xml.

3.2 iOS project

The react-native-fbsdk has been linked by rnpm, the next step will be downloading and linking the native Facebook SDK for iOS. Make sure you have the latest Xcode installed. Open the .xcodeproj in Xcode found in the ios subfolder from your project's root directory. Now, follow all the steps in the Getting Started Guide for Facebook SDK for iOS. Along with FBSDKCoreKit.framework, don't forget to import FBSDKShareKit.framework and FBSDKLoginKit.framework into your Xcode project.

3.3 Troubleshooting

  1. I cannot run the Android project.
  • Make sure you added the code snippet in step 3.1.
  • Make sure you set up a Facebook app and updated the AndroidManifest.xml and res/values/strings.xml with Facebook app settings.
  1. I get a build error stating that one of the Facebook SDK files was not found -- eg. FBSDKLoginKit/FBSDKLoginKit.h file not found.
  • Make sure that the Facebook SDK frameworks are installed in ~/Documents/FacebookSDK.
  • Make sure that FBSDK[Core, Login, Share]Kit.framework show up in the Link Binary with Libraries section of your build target's Build Phases.
  • Make sure that ~/Documents/FacebookSDK is in the Framework Search Path of your build target's Build Settings.
  1. I get build errors like Warning: Native component for "RCTFBLikeView" does not exist:
  • Make sure that libRCTFBSDK.a shows up in the Link Binary with Libraries section of your build target's Build Phases.
  1. I get this build error: no type or protocol named UIApplicationOpenURLOptionsKey:
  • Your XCode version is too old, upgrade to XCode 8.0+.

Usage

Login

Login Button + Access Token

const FBSDK = require('react-native-fbsdk');
const {
  LoginButton,
  AccessToken
} = FBSDK;

var Login = React.createClass({
  render: function() {
    return (
      <View>
        <LoginButton
          publishPermissions={["publish_actions"]}
          onLoginFinished={
            (error, result) => {
              if (error) {
                alert("login has error: " + result.error);
              } else if (result.isCancelled) {
                alert("login is cancelled.");
              } else {
                AccessToken.getCurrentAccessToken().then(
                  (data) => {
                    alert(data.accessToken.toString())
                  }
                )
              }
            }
          }
          onLogoutFinished={() => alert("logout.")}/>
      </View>
    );
  }
});

Requesting additional permissions with Login Manager

You can also use the Login Manager with custom UI to perform Login.

const FBSDK = require('react-native-fbsdk');
const {
  LoginManager,
} = FBSDK;

// ...

// Attempt a login using the Facebook login dialog asking for default permissions.
LoginManager.logInWithReadPermissions(['public_profile']).then(
  function(result) {
    if (result.isCancelled) {
      alert('Login cancelled');
    } else {
      alert('Login success with permissions: '
        +result.grantedPermissions.toString());
    }
  },
  function(error) {
    alert('Login fail with error: ' + error);
  }
);

Sharing

Share dialogs

All of the dialogs included are used in a similar way, with differing content types. All content types are defined with Flow Type Annotation in js/models directory.

const FBSDK = require('react-native-fbsdk');
const {
  ShareDialog,
} = FBSDK;

// ...

// Build up a shareable link.
const shareLinkContent = {
  contentType: 'link',
  contentUrl: "https://facebook.com",
  contentDescription: 'Wow, check out this great site!',
};

// ...

// Share the link using the share dialog.
shareLinkWithShareDialog() {
  var tmp = this;
  ShareDialog.canShow(this.state.shareLinkContent).then(
    function(canShow) {
      if (canShow) {
        return ShareDialog.show(tmp.state.shareLinkContent);
      }
    }
  ).then(
    function(result) {
      if (result.isCancelled) {
        alert('Share cancelled');
      } else {
        alert('Share success with postId: '
          + result.postId);
      }
    },
    function(error) {
      alert('Share fail with error: ' + error);
    }
  );
}

Share API

Your app must have the publish_actions permission approved to share through the share API. You should prefer to use the Share Dialogs for an easier and more consistent experience.

const FBSDK = require('react-native-fbsdk');
const {
  ShareApi,
} = FBSDK;

// ...

// Build up a shareable link.
const shareLinkContent = {
  contentType: 'link',
  contentUrl: "https://facebook.com",
  contentDescription: 'Wow, check out this great site!',
};

// ...

// Share using the share API.
ShareApi.canShare(this.state.shareLinkContent).then(
  var tmp = this;
  function(canShare) {
    if (canShare) {
      return ShareApi.share(tmp.state.shareLinkContent, '/me', 'Some message.');
    }
  }
).then(
  function(result) {
    alert('Share with ShareApi success.');
  },
  function(error) {
    alert('Share with ShareApi failed with error: ' + error);
  }
);

Analytics

App events

const FBSDK = require('react-native-fbsdk');
const {
  AppEventsLogger,
} = FBSDK;

// ...

// Log a $15 purchase.
AppEventsLogger.logPurchase(15, 'USD', {'param': 'value'})

Graph API

Graph Requests

const FBSDK = require('react-native-fbsdk');
const {
  GraphRequest,
  GraphRequestManager,
} = FBSDK;

// ...

//Create response callback.
_responseInfoCallback(error: ?Object, result: ?Object) {
  if (error) {
    alert('Error fetching data: ' + error.toString());
  } else {
    alert('Success fetching data: ' + result.toString());
  }
}

// Create a graph request asking for user information with a callback to handle the response.
const infoRequest = new GraphRequest(
  '/me',
  null,
  this._responseInfoCallback,
);
// Start the graph request.
new GraphRequestManager().addRequest(infoRequest).start();
