npm module for react-native apps to integrate Braintree v.zero SDK.

Example

https://github.paypal.com/ProfessionalServiceEngineering/react-native-braintree-vzero/tree/master/BraintreeDemo

iOS

Installation

react-native init BraintreeDemo (skip for existing projects)
Run npm install react-native-braintree-vzero --save to add the package
Run rnpm link (First run npm install rnpm -g if you don't have rnpm already)
or
Use manual instructions under Linking Libraries https://facebook.github.io/react-native/docs/linking-libraries-ios.html
Create a group called Frameworks and add the Braintree iOS frameworks from $(SRCROOT)/../node_modules/react-native-braintree-vzero/ios path.
Go to General -> Embedded Binaries and add the Braintree iOS frameworks from the Frameworks group created from above step.
Make sure Other Linker Flags has $(inherited), -ObjC and -lc++.
Add $(SRCROOT)/../node_modules/react-native-braintree-vzero/ios under Framework Search Paths.

If your app is built using iOS 9 as its Base SDK, then you must add URLs to a whitelist in your app's info.plist:

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>com.paypal.ppclient.touch.v1</string>
  <string>com.paypal.ppclient.touch.v2</string>
  <string>com.venmo.touch.v2</string>
</array>

Skip if you don't need PayPal and/or One Touch. There are two choices we can adapt for URLSchemes. For now, we'll stick to the one recommended by official Braintree iOS setup guidelines. Goto Info -> URL Types and add org.your.bundle.indentifier.payments and below lines to AppDelegate.m of your iOS project.
```
#import <BraintreeCore/BraintreeCore.h>
```

(BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions { ...
BTAppSwitch setReturnURLScheme:@"org.your.bundle.indentifier.payments";
... }
```
```objective-c
```
(BOOL)application:(UIApplication )application openURL:(NSURL )url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { if (url.scheme localizedCaseInsensitiveCompare:@"org.your.bundle.indentifier.payments" == NSOrderedSame) { return BTAppSwitch handleOpenURL:url sourceApplication:sourceApplication; } return NO; }

BraintreeClient.initWithAuthorization(clientToken, function(result) {
  if(result == true){
    // Braintree client initialization with the client token successful
    // Call the Drop-In view
  }
  else{
    // The initialization failed

});

Presenting Braintree Drop-In UI

var options = {
  bgColor: processColor('yellow'),
  tintColor: processColor('red'),
  barBgColor: processColor('green'),
  barTintColor: processColor('white'),
  paymentControllertitle: 'Pay with Braintree v.zero',
  submitButtonTitle: 'Pay'
};

BraintreeClient.dropInViewController(options, function(err, nonce) {

  if(err){
    // Check if there was an error
  }
  else{
    // Check if nonce is null, if not use it to complete the  transaction
  }

});

Presenting PayPal UI

BraintreeClient.payPalViewController(function(err, nonce) {

  if(err){
    // Check if there was an error
  }
  else{
    // Check if nonce is null, if not use it to complete the  transaction
  }

});

Get card nonce for Custom Credit Card UI

var credtCardNumber = '4111111111111111', expMonth = '12', expYear = '2020', cvvNumber = '123';

BraintreeClient.getCardNonce(credtCardNumber, expMonth, expYear, cvvNumber, function(err, nonce) {

  if(err){
    // Check if there was an error
  }
  else{
    // Check if nonce is null, if not use it to complete the  transaction
  }

});

Android

Installation

react-native init BraintreeDemo (skip for existing projects)
Run npm install react-native-braintree-vzero --save to add the package

Add the following to android/settings.gradle

Browser switch setup

For PayPal a URL scheme must be defined to accept return browser switches.

Edit your AndroidManifest.xml to include BraintreeBrowserSwitchActivity and set the android:scheme:

<activity android:name="com.braintreepayments.api.BraintreeBrowserSwitchActivity"
    android:launchMode="singleTask">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="${applicationId}.braintree" />
    </intent-filter>
</activity>
