React Native FBSDK Next

This project aims to keep continuity of the React Native FBSDK from Facebook. As Facebook dropped support from it. As a community for this is our effort in order to keep upgrading and improving support for this module.

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

React Native Compatibility

To use this library you need to ensure you match up with the correct version of React Native you are using.

FB SDK	lib version	Required React Native Version
>= 9.0.0+	`react-native-fbsdk-next` `>= 3.0.1`	`>= 0.60`
<= 8.0.1	`react-native-fbsdk` `>= 1.0.0`	`>= 0.60`
<= 8.0.1	`react-native-fbsdk` `<= 0.10`	`<= 0.59.x`

1. Install the library

using either Yarn:

yarn add react-native-fbsdk-next

or npm:

npm install --save react-native-fbsdk-next

2. Link

React Native 0.60+

CLI autolink feature links the module while building the app.

Note For iOS using cocoapods, run:

$ cd ios/ && pod install

React Native <= 0.59

For support with React Native <= 0.59, please refer to React Native FBSDK

If you can't or don't want to use the CLI tool, you can also manually link the library using the instructions below (click on the arrow to show them):

Manually link the library on iOS

Either follow the instructions in the React Native documentation to manually link the framework or link using Cocoapods by adding this to your Podfile:

pod 'react-native-fbsdk', :path => '../node_modules/react-native-fbsdk'

Manually link the library on Android

Make the following changes:

`android/settings.gradle`

include ':react-native-fbsdk-next'
project(':react-native-fbsdk-next').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fbsdk-next/android')

`android/app/build.gradle`

dependencies {
   ...
   implementation project(':react-native-fbsdk-next')
}

`android/app/src/main/.../MainApplication.java`

On top, where imports are:

import com.facebook.reactnative.androidsdk.FBSDKPackage;

Add the FBSDKPackage class to your list of exported packages.

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

3. Configure projects

3.1 Android

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 updating strings.xml and AndroidManifest.xml.

3.2 iOS

Follow steps 3 and 4 in the Getting Started Guide for Facebook SDK for iOS.

If you're not using cocoapods already you can also follow step 1.1 to set it up.

If you're using React Native's RCTLinkingManager

The AppDelegate.m file can only have one method for openUrl. If you're also using RCTLinkingManager to handle deep links, you should handle both results in your openUrl method.

- (BOOL)application:(UIApplication *)app
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  if ([[FBSDKApplicationDelegate sharedInstance] application:app openURL:url options:options]) {
    return YES;
  }

  if ([RCTLinkingManager application:app openURL:url options:options]) {
    return YES;
  }

  return NO;
}

Troubleshooting

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.

Duplicate symbol errors

Make sure that FBSDK[Core, Login, Share]Kit.framework are NOT in Link Binary with Libraries for your root project when using cocoapods.

I get this build error: no type or protocol named UIApplicationOpenURLOptionsKey:

Your Xcode version is too old. Upgrade to Xcode 10.0+.

After facebook-ios-sdk v7 you need to create a swift file into the main project folder:

File.Swift

Usage

SDK Initialization

To comply with Apple privacy requirements, for iOS the autoInitEnabled option is removed from facebook-ios-sdk#v9.0.0.

Using this module, there are two options to comply with this requirement, one is platform-neutral and can be used from your javascript code whenever it makes sense for your app, and one is native.

Platform-neutral SDK initialization

If you do not need to handle a GDPR-type opt-in flow, on iOS you should include the following javascript code as early in startup as possible. For Android auto-init is the default still, so this is not strictly necessary for Android but will work.

If you need to handle a GDPR-type flow, make sure your SDK is configured natively to delay all logging activity according to the GDPR instructions, ask for user consent, and after obtaining consent include code similar to this:

import { Settings } from 'react-native-fbsdk-next';

// Ask for consent first if necessary
// Possibly only do this for iOS if no need to handle a GDPR-type flow
Settings.initializeSDK();

iOS Native Initialization

If you would like to initialize the Facebook SDK even earlier in startup for iOS, you need to include this code in your AppDelegate.m file now that auto-initialization is removed.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [FBSDKApplicationDelegate initializeSDK:launchOptions]; // <- add this

  // your other stuff
}

Login

Login Button + Access Token

import React, { Component } from 'react';
import { View } from 'react-native';
import { LoginButton, AccessToken } from 'react-native-fbsdk-next';

export default class Login extends Component {
  render() {
    return (
      <View>
        <LoginButton
          onLoginFinished={
            (error, result) => {
              if (error) {
                console.log("login has error: " + result.error);
              } else if (result.isCancelled) {
                console.log("login is cancelled.");
              } else {
                AccessToken.getCurrentAccessToken().then(
                  (data) => {
                    console.log(data.accessToken.toString())
                  }
                )
              }
            }
          }
          onLogoutFinished={() => console.log("logout.")}/>
      </View>
    );
  }
};

Requesting additional permissions with Login Manager

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

// ...

import { LoginManager } from "react-native-fbsdk-next";

// ...

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

// ...

import { ShareDialog } from 'react-native-fbsdk-next';

// ...

// 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) {
        console.log('Share cancelled');
      } else {
        console.log('Share success with postId: '
          + result.postId);
      }
    },
    function(error) {
      console.log('Share fail with error: ' + error);
    }
  );
}

Share Photos

See SharePhotoContent and SharePhoto to refer other options.

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

const photoUri = 'file://' + '/path/of/photo.png'
const sharePhotoContent = {
  contentType = 'photo',
  photos: [{ imageUrl: photoUri }],
}

// ...

ShareDialog.show(tmp.state.sharePhotoContent);

Share Videos

See ShareVideoContent and ShareVideo to refer other options.

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

const videoUri = 'file://' + '/path/of/video.mp4'
const shareVideoContent = {
  contentType = 'video',
  video: { localUrl: videoUri },
}

// ...

ShareDialog.show(tmp.state.shareVideoContent);

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.

// ...

import { ShareApi } from 'react-native-fbsdk-next';

// ...

// 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) {
    console.log('Share with ShareApi success.');
  },
  function(error) {
    console.log('Share with ShareApi failed with error: ' + error);
  }
);

Analytics

App events

// ...

import { AppEventsLogger } from "react-native-fbsdk-next";

// ...

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

Graph API

Graph Requests

// ...

import { GraphRequest, GraphRequestManager } from 'react-native-fbsdk-next';

// ...

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