React Native plug-in for SAP Customer Data Cloud

REUSE status

Description

A React Native plugin for interfacing with SAP Customer Data Cloud. This plugin provides quick access to core elements & business API flows available within SAP Customer Data Cloud; designed for React Native mobile applications.

Requirements

Android SDK support requires Android SDK 23 and above (For Biometric capabilities, SDK 23 and above is required). iOS support requires iOS 10 and above.

Download and Installation

Add the plugin in your package.json file.

Setup & Gigya core integration

Android setup

Android v7 upgrade

Plugin version 0.3.0+ will depend on Android SDK core v7. Required changes to your plugin based on Android SDK core v7 are documented in the Android core documentation

Add the following to your MainApplication.java file:

@Override
  public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
    initializeFlipper(this, getReactNativeHost().getReactInstanceManager());

    // Set and initialize the account schema for the Gigya core SDK.
    GigyaSdkModule.setSchema(this, GigyaAccount.class);
  }

iOS setup

Navigate to AppDelegate.m and add the following under the: **(BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions method.

GigyaExtension * gigya = [[GigyaExtension alloc] init];
[gigya setMySchema];

To apply your custom schema, you will need to create a 'swift bridge' file and register it as follows:

@objc public class GigyaExtension: NSObject {
    @objc func setMySchema() {
        GigyaSdk.setSchema(HostModel.self)
    }
}

And then call the function from your AppDelegate.m file.

SDK initialization

In your application code, you can initialize the Gigya SDK using the following call:

Gigya.initFor("Your API KEY", "API DOMAIN");

If you do not specify the "API DOMAIN" (as implemented in the sample application) the SDK will use the default us1.gigya.com domain.

Run the example application

To run the example application included in the repository:

  1. Checkout the repository code.
  2. Navigate to the example folder and run the yarn install command.
  3. Navigate to the example/ios folder and run the pod install command.

** Android - If changing the API key, make sure to update the signingConfigs section as the example app includes a specific keystore path used for testing purposes ***

signingConfigs {

        debug {
            storeFile file('debug.keystore')
            storePassword 'android'
            keyAlias 'androiddebugkey'
            keyPassword 'android'
        }
    }

Sending a simple request

Sending a request is available using the plugin's send method.

try {
      const send = await Gigya.send("socialize.getSDKConfig");
      console.log("send: " + JSON.stringify(senddd));
    } catch (error) {
      console.log("errorSend:" + error);
    }

Business APIs

The plugin provides an interface to these core SDK business APIs: login, register, getAccount, setAccount, isLoggedIn ,logOut, addConnection, removeConnection Implement them using the same request structure as shown above. The example application includes various different implementations.

Social login

Use the "socialLogin" interface to perform social login using supported providers. The React Native plugin supports the same *providers supported by the Core Gigya SDK.

Supported social login providers: google, facebook, line, wechat, apple, amazon, linkedin, yahoo.

For example:

const send = await Gigya.socialLogin("facebook");

Embedded social providers

Android v7 upgrade

Plugin version 0.3.0+ will depend on Android SDK core v7. Please view the changes required to be made to yours applicationin the Android code documentation for updateing to external providers usage.

Specific social providers (Facebook, Google) require additional setup. This is due to their requirement for specific (embedded native) SDKs.

To register social providers you will need to create a 'swift bridge' file (same as with using a custom schema). Don't forget to add the relevant wrappers to the ios folder.

Facebook

Follow the core SDK documentation and instructions for setting up Facebook login. Android documentation iOS documentation

Google

Follow the core SDK documentation and instructions for setting up Google login. Android documentation iOS documentation

LINE

To provide support for LINE as a provider, please follow it's core SDK documentation. Android documentation iOS documentation

WeChat

To provider support for WeChat as a provider, please follow the core SDK documentation. Android documentation iOS documentation

Using screen-sets

The plugin supports the use of Web screen-sets using the following:

Gigya.showScreenSet("Default-RegistrationLogin", (event, data) => {
      console.log(`event: ${event}`);
      if (event == "onLogin") {
        updateIsLoggedIn(Gigya.isLoggedIn())
      }
    })

Optional {params} map is available.

As in the core SDKs, the plugin provides a streaming channel that will stream the Screen-Sets events (event, map).

event - actual event name. data - event data map.

Mobile SSO

The plugin supports the native SDK's "Single Sign On feature". Andorid iOS

Please make sure to implement the nessesary steps described for each platform.

To initiate the flow run the following snippet.

 const send = await Gigya.sso();
 });

Note: When using mobile SSO (single sign-on using the central login page), logging out using the SDK's logout method will only log the user out of the current API key used. The user will not be logged out of the other group sites.

Resolving interruptions

Much like our core SDKs, resolving interruptions is available using the plugin.

Current supporting interruptions:

  • pendingRegistration
  • conflictingAccounts

Example for resolving conflictingAccounts interruptions:

try {
      const send = await Gigya.register(login, password, { 'sessionExpiration': 0 });
      console.log("send: " + JSON.stringify(senddd));
      updateIsLoggedIn(Gigya.isLoggedIn())

    } catch (error) {
      console.log("register error:" + error);

      const e = error as GigyaError;
      switch (e.getInterruption()) {
        case GigyaInterruption.conflictingAccounts: {
          const resolver = Gigya.resolverFactory.getResolver(e) as LinkAccountResolver;

          console.log("link:")
          console.log(resolver.regToken)

          break
        }
      }
    }

Once you reference your resolver, create your relevant UI to refelct if a site or social linking is required (see example app for details) and use the relevant method.

Example of resolving link to the site when trying to link a new social account to a site account.

const loginToSite = await resolver.linkToSite(userData.login, userData.password)

Biometric support

The plugin provides Android/iOS biometric support for these flows.

An end user logs in.
An end user decides to use biometric authentication.
This requires the end user to verify their fingerprint.
The app is locked or deleted from memory.
The end user needs to unlock the app to restore his session.
In this case, the end user needs to verify his fingerprint.
The end user decides not to use biometric authentication

The biometric fingerprint feature is a security cipher that is placed on top of an existing session of your app, so invoking biometric operations requires a valid session.

Please make sure you are using native implementations:

iOS 1. The device has a passcode.

  1. the device has TouchID/FaceID.

**FaceID To use FaceID in a compatible device, you must include the following key in your Info.plist file.

NSFaceIDUsageDescription = (String) "Your own message ". If you also want to set a custom text in the Touch ID prompt, you can include the following key:

GigyaTouchIDMessage = (String) "Your custom message" (Default = "Please authenticate to continue").

Android

  1. Android SDK 23 and above is required.
  2. the device has a fingerprint sensor.
  3. at least 1 fingerprint is already registered on the device.
  4. appropriate permissions are already requested in the library manifest: android.permission.USE _FINGERPRINT android.permission. USE _BIOMETRIC

Declaring the prompt display. Andorid's biometric authentication uses a prompt display. You can customize the text displayed by declaring your own BiometricPromptInfo object.

In your application class (after launching the SDK), you can add the following:

GigyaSdkBiometricModule.setBiometricPromptInfo(new GigyaPromptInfo( "title", "subtitle", "description" ));

If no prompt info is specified, the prompt window uses default English texts.

Errors

Biometric errors from version 0.2.0 will return as String values and not as Boolean values. This is to accomodate unique errors such as "Key invalidated", which will render the session as unrecoverable and require the user to re-authenticate.

FIDO/WebAuthn Authentication

FIDO is a passwordless authentication method that allows password-only logins to be replaced with secure and fast login experiences across websites and apps. Our SDK provides an interface to register a passkey or login, revoke passkeys created using FIDO/Passkeys and is backed by our WebAuthn service.

Follow the platform implementation guides: Swift Android

Additional setup for Android: To correctly integrate Android with the FIDO library, do the following:

  1. Add the following code snippet to your MainActivity class:
private ActivityResultLauncher<IntentSenderRequest> resultLauncher = registerForActivityResult(
            new ActivityResultContracts.StartIntentSenderForResult(),
            new ActivityResultCallback<ActivityResult>() {
                @Override
                public void onActivityResult(ActivityResult result) {
                    Gigya.getInstance().WebAuthn().handleFidoResult(result);
                }
            }
    );
  1. Reference the "resultLauncher" class within the "onCreate" method of the activity.
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        GigyaWebAuthnModule.resultLauncher = resultLauncher;
    }

The "resultLauncher" object is required for intercommunicating with the FIDO library.

Usage example Login with FIDO/WebAuthn passkey:

try {
      var operation = await Gigya.webAuthn.login()
      console.log("webAuthnLogin success " + operation)
      // Update login state.
    } catch (e) {
        console.log("webAuthnLogin error " + e)
    }

Register a new FIDO/WebAuthn passkey:

try {
      var operation = await Gigya.webAuthn.register()
      console.log("webAuthnRegister success " + operation)
    } catch (e) {
        console.log("webAuthnRegister error " + e)
    } 

Revoke an existing FIDO/WebAuthn passkey:

try {
      var operation = await Gigya.webAuthn.revoke()
      console.log("webAuthnRevoke success " + operation)
      // Update login state.
    } catch (e) {
        console.log("webAuthnRevoke error " + e)
    }
