React Native FBSDK

React Native FBSDK is a wrapper around the iOS 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 never have to call a single native function directly.

Functionality is provided through three separate npm packages so you never have to include more than you need:

• react-native-fbsdkcore
• react-native-fbsdkshare
• react-native-fbsdklogin

Usage

react-native-fbsdkcore

Graph Requests

var FBSDKCore = require('react-native-fbsdkcore');
var {
  FBSDKGraphRequest,
} = FBSDKCore;

// ...

// Create a graph request asking for friends with a callback to handle the response.
var fetchFriendsRequest = new FBSDKGraphRequest((error, result) => {
  if (error) {
    alert('Error making request.');
  } else {
    // Data from request is in result
  }
}, '/me/friends');
// Start the graph request.
fetchFriendsRequest.start();

// ...

App events

var FBSDKCore = require('react-native-fbsdkcore');
var {
  FBSDKAppEvents,
} = FBSDKCore;

// ...

// Log a $15 purchase.
FBSDKAppEvents.logPurchase(15, 'USD', null, null)

// ...

react-native-fbsdklogin

Login Button

var FBSDKLogin = require('react-native-fbsdklogin');
var {
  FBSDKLoginButton,
} = FBSDKLogin;

var Login = React.createClass({
  render: function() {
    return (
      <View>
        <FBSDKLoginButton
          onLoginFinished={(error, result) => {
            if (error) {
              alert('Error logging in.');
            } else {
              if (result.isCanceled) {
                alert('Login cancelled.');
              } else {
                alert('Logged in.');
              }
            }
          }}
          onLogoutFinished={() => alert('Logged out.')}
          readPermissions={[]}
          publishPermissions={['publish_actions']}/>
      </View>
    );
  }
});

Login Manager

var FBSDKLogin = require('react-native-fbsdklogin');
var {
  FBSDKLoginManager,
} = FBSDKLogin;

// ...

// Attempt a login using the native login dialog asking for default permissions.
FBSDKLoginManager.setLoginBehavior(GlobalStore.getItem('behavior', 'native'));
FBSDKLoginManager.logInWithReadPermissions([], (error, result) => {
  if (error) {
    alert('Error logging in.');
  } else {
    if (result.isCanceled) {
      alert('Login cancelled.');
    } else {
      alert('Logged in.');
    }
  }
});

// ...

react-native-fbsdkshare

Share dialogs

All of the dialogs included are used in a similar way, with differing content types.

var FBSDKShare = require('react-native-fbsdkshare');
var {
  FBSDKShareDialog,
  FBSDKShareLinkContent,
} = FBSDKShare;

// ...

// Build up a shareable link.
var linkContent = new FBSDKShareLinkContent('https://facebook.com', 'Wow, check out this great site!', 'Facebook.com', null);
// Share the link using the native share dialog.
FBSDKShareDialog.show(linkContent, (error, result) => {
  if (!error) {
    if (result.isCancelled) {
      alert('Share canceled.');
    } else {
      alert('Thanks for sharing!');
    }
  } else {
    alert('Error sharing.');
  }
});

// ..

Share API

Your app must have the publish_actions permission approved to share through the share API.

var FBSDKShare = require('react-native-fbsdkshare');
var {
  FBSDKShareAPI,
  FBSDKSharePhoto,
  FBSDKSharePhotoContent,
} = FBSDKShare;

// ...

// Build up a shareable photo, where 'cat.png' is included in the project. A data URI encoding the image can also be passed.
var photo = new FBSDKSharePhoto('cat.png', true);
var photoContent = new FBSDKSharePhotoContent([photo]);
// Share using the share API.
FBSDKShareAPI.share(photoContent, "/me", "Check out this cat!", (error, result) => {
  if (error) {
    alert('Error sharing');
  } else {
    alert('Shared successfully');
  }
});

// ...

Running the Sample App

Without CocoaPods

• From the Sample/ folder, run npm install
• Download and install the Facebook SDK for iOS. The Xcode projects assume that they're installed in the standard location at ~/Documents/FacebookSDK.
• Open NHSample.xcodeproj
• Build and run the app to try it out.

With CocoaPods

• From the Sample/ folder, run npm install followed by pod install
• Open NHSample-CocoaPods.xcworkspace
• Build an run the app to try it out. Ensure the target you're building is the NHSample app and not just one of the libraries.

Installation

JavaScript packages

Depending on what functionality you're looking to integrate, install any of the following packages as npm dependencies:

• npm install --save react-native-fbsdkcore for graph requests, app events, etc.
• npm install --save react-native-fbsdkshare for share buttons, dialogs, etc.
• npm install --save react-native-fbsdklogin for login button and manager.

Native iOS code

You will also have to add the native iOS code from these packages as well as the Facebook SDK for iOS to your app's XCode. There are multiple ways of doing this.

Note: Any of the options below assume you've already installed the npm packages as mentioned above.

Option: Using CocoaPods

Assuming you have CocoaPods installed, create a PodFile like this in your app's project directory. You can leave out the modules you don't need.

source 'https://github.com/CocoaPods/Specs.git'
pod 'React', :subspecs => ['Core', 'RCTImage', 'RCTNetwork', 'RCTText', 'RCTWebSocket'], :path => 'node_modules/react-native'
pod 'react-native-fbsdkcore', :path => 'node_modules/react-native-fbsdkcore'
pod 'react-native-fbsdklogin', :path => 'node_modules/react-native-fbsdklogin'
pod 'react-native-fbsdkshare', :path => 'node_modules/react-native-fbsdkshare'

Now run pod install. This will automatically download the Facebook SDK for iOS and create an Xcode workspace containing all native files. From now on open YourApp.xcworkspace instead of YourApp.xcodeproject in Xcode. Because React Native's iOS code is now pulled in via CocoaPods, you also need to remove the React, RCTImage, etc. subprojects from your app's Xcode project.

Follow the Getting Started guide to set up a Facebook app, configure your Xcode project, and set up the app delegate. You can skip the steps that talk about downloading and linking the Facebook SDK frameworks -- that's already taken care of by CocoaPods.

Option: Using the provided Xcode projects

Download and install the Facebook SDK for iOS into the standard location at ~/Documents/FacebookSDK. Follow the Getting Started guide to link your app's project with the Facebook SDK frameworks and set up the app delegate.

Add any of the following Xcode projects to your app's Xcode project:

• node_modules/react-native-fbsdkcore/RCTFBSDKCore.xcodeproj
• node_modules/react-native-fbsdklogin/RCTFBSDKLogin.xcodeproj
• node_modules/react-native-fbsdkshare/RCTFBSDKShare.xcodeproj Follow the Linking Libraries (iOS) guide for each of them to make sure they're added correctly to your project's build targets.

Option: Manually add files to Xcode

Download and install the Facebook SDK for iOS into the standard location at ~/Documents/FacebookSDK. Follow the Getting Started guide to link your app's project with the Facebook SDK frameworks and set up the app delegate.

Drag any of the following directories into your app's Xcode project:

• node_modules/react-native-fbsdkcore/iOS
• node_modules/react-native-fbsdklogin/iOS
• node_modules/react-native-fbsdkshare/iOS Keep in mind that if you update any of the react-native-fbsdk modules, files may have been added, removed, or renamed.

All options: configure your app

Troubleshooting

• If you get a build error stating that one of the Facebook SDK files was not found -- eg. FBSDKCoreKit/FBSDKCoreKit.h -- check two things:
  • Ensure that the Facebook SDK frameworks are installed and in the right place.
  • Add the folder where the Facebook SDK was to the project's framework search path in Xcode. See Apple's documentation on including frameworks.

Developers looking to integrate with the Facebook Platform should familiarize themselves with the Facebook Platform Policy.
