react-native-branch

Native Wrapper around Branch Metrics native SDKs. Tested with React Native 0.21.0.

Supports iOS and Android.

Usage

var branch = require('react-native-branch');

//Receives the initSession's result as soon as it becomes available
branch.getInitSessionResultPatiently(({params, error}) => { });

branch.setDebug();
branch.getLatestReferringParams((params) => { });
branch.getFirstReferringParams((params) => { });
branch.setIdentity("Your User's ID");
branch.userCompletedAction("Purchased Item", {item: 123});

var shareOptions = {messageHeader: "Check this out!", messageBody: "Check this cool thing out: "};
var branchUniversalObject = {canonicalIdentifier: "RNBranchSharedObjectId", contentTitle: "Cool Content!", contentDescription: "Cool Content Description", contentImageUrl: ""};
var linkProperties = {feature: 'share', channel: 'RNApp'};
branch.showShareSheet(shareOptions, branchUniversalObject, linkProperties, ({channel, completed, error}) => {});

branch.logout();

Installation

npm install rnpm -g
npm install --save react-native-branch
rnpm link react-native-branch
cd node_modules/react-native-branch
pod install #Only required for iOS

Android

Step 0 - Verify Library Linking

Sometimes rnpm link creates incorrect relative paths, leading to compilation errors

Ensure that the following files look as described and all linked paths are correct

// file: android/settings.gradle
...

include ':react-native-branch', ':app'

// The relative path to the react-native-branch directory tends to often be prefixed with one too many "../"s
project(':react-native-branch').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-branch/android')

// file: android/app/build.gradle
...

dependencies {
    ...
    compile project(':react-native-branch')
}

Step 1 - Initialize the RNBranchModule

// file: android/app/src/main/java/com/xxx/MainActivity.java

import android.content.Intent; // <-- import
import com.dispatcher.rnbranch.*; // <-- import

public class MainActivity extends ReactActivity {
    // ...

    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            new RNBranchPackage() // <-- add this line, if not already there
        );
    }
    
    // Add onStart
    @Override
    public void onStart() {
        super.onStart();

        RNBranchModule.initSession(this.getIntent().getData(), this);
    }
    
    // Add onNewIntent
    @Override
    public void onNewIntent(Intent intent) {
        this.setIntent(intent);
    }
    
    // ...  
} 

Step 2 - Configure Manifest

Please follow [these instructions] (https://dev.branch.io/getting-started/sdk-integration-guide/guide/android/#configure-manifest)

Step 3 - Register for Google Play Install Referrer

Please follow these instructions

Note: The "receiver" element needs to be added to the "application" node in AndroidManifest.xml

Step 4 - Register a URI scheme

Please follow these instructions

Notes:

• The "intent-filter" element needs to be added to the activity node, whose android:name is "com.yourAppName.MainActivity". This node is in the "application" node.
• If you already have an intent-filter tag, this has to be added as an additional one.
• Make sure to replace "yourApp" with the scheme you specified in the Branch dashboard.

Step 5 - Enable Auto Session Management

Please follow these instructions

Note: Just add the "android:name" attribute to your "application" node in your AndroidManifest.xml

Step 6 - Enable App Links for Android M and above (Optional but Recommended)

Please follow these instructions

iOS

Step 1 - Modifications to your React Native XCode Project

• Drag and Drop /node_modules/react-native-branch/Pods/Pods.xcodeproj into the Libraries folder of your project in XCode (as described in Step 1 here)
• Drag and Drop the Pods.xcodeproj's Products's libBranch.a into your project's target's "Linked Frameworks and Libraries" section (as described in Step 2 here)

Step 2 - Modifications to AppDelegate.m

Import RNBranch.h at the top

#import "RNBranch.h"

Initialize the Branch Session in didFinishLaunchingWithOptions

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [RNBranch initSessionWithLaunchOptions:launchOptions isReferrable:YES];
  
  NSURL *jsCodeLocation;
  ///
}

Add the openURL and continueUserActivity functions

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
  if (![RNBranch handleDeepLink:url]) {
    // do other deep link routing for the Facebook SDK, Pinterest SDK, etc
  }
  return YES;
}

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray *restorableObjects))restorationHandler {
  return [RNBranch continueUserActivity:userActivity];
}

Step 3 - Add the branch_key to your plist

Add a String entry branch_key with your branch key to your plist (as described here)

Step 4 - Register a URI Scheme for Direct Deep Linking (Optional but Recommended)

Please follow these instructions here

Step 5 - Configure for Universal Linking

Please follow these instructions here
