React Native AEP Optimize Extension

@adobe/react-native-aepoptimize is a wrapper around the iOS and Android Adobe Experience Platform Optimize Extension to allow for integration with React Native applications.

Peer Dependencies

The Adobe Experience Platform Optimize extension has the following peer dependency, which must be installed prior to installing the optimize extension:

• Core
• Edge
• Edge Identity

Installation

See Requirements and Installation instructions on the main page

Install the @adobe/react-native-aepoptimize package:

NPM:

npm install @adobe/react-native-aepoptimize

Yarn:

yarn add @adobe/react-native-aepoptimize

Usage

Initializing and registering the extension

Initialization of the SDK should be done in native code, documentation on how to initialize the SDK can be found here.

Example:

iOS

@import AEPCore;
@import AEPLifecycle;
@import AEPEdge;
@import AEPEdgeIdentity;
@import AEPOptimize;

@implementation AppDelegate
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [AEPMobileCore setLogLevel: AEPLogLevelDebug];
  [AEPMobileCore configureWithAppId:@"yourAppID"];

  const UIApplicationState appState = application.applicationState;

  [AEPMobileCore registerExtensions: @[AEPMobileEdge.class, AEPMobileEdgeIdentity.class, AEPMobileOptimize.class] completion:^{
    if (appState != UIApplicationStateBackground) {
       [AEPMobileCore lifecycleStart:nil];
    }
  }];
  return YES;
}
@end

    super.onCreate();
    ...
    MobileCore.setApplication(this);
    MobileCore.setLogLevel(LoggingMode.DEBUG);
    MobileCore.configureWithAppID("yourAppID");
    List<Class<? extends Extension>> extensions = Arrays.asList(
                Edge.EXTENSION,
                Identity.EXTENSION,
                Optimize.EXTENSION);
    MobileCore.registerExtensions(extensions, o -> {
      MobileCore.lifecycleStart(null);
    });
  }
}

Importing the extension:

import {
  Optimize,
  Offer,
  Proposition,
  DecisionScope,
} from "@adobe/react-native-aepoptimize";

API reference

Clearing the cached Propositions:

Syntax

clearCachedPropositions();

Example

Optimize.clearCachedPropositions();

Getting the SDK version:

Syntax

extensionVersion(): Promise<string>

Example

Optimize.extensionVersion().then(newVersion => console.log("AdobeExperienceSDK: Optimize version: " + newVersion);

Getting the Cached Propositions:

This API returns the cached propositions for the provided DecisionScopes from the in-memory Proposition cache.

Syntax

getPropositions(decisionScopes: Array<DecisionScope>): Promise<Map<string, Proposition>>

Example

const decisionScopeText = new DecisionScope("{DecisionScope name}");
const decisionScopeImage = new DecisionScope("{DecisionScope name}");
const decisionScopeHtml = new DecisionScope("{DecisionScope name{");
const decisionScopeJson = new DecisionScope("{DecisionScope name}");
const decisionScopes = [
  decisionScopeText,
  decisionScopeImage,
  decisionScopeHtml,
  decisionScopeJson,
];

Optimize.getPropositions(decisionScopes).then(
  (propositions: Map<string, typeof Proposition>) => {
    //Your app logic using the propositions
  }
);

Adding onPropositionUpdate callback:

Callback that will be called with the updated Propositions.

Syntax

onPropositionUpdate(adobeCallback: AdobeCallback)

Example

Optimize.onPropositionUpdate({
  call(proposition: Map<String, typeof Proposition>) {
    //App logic using the updated proposition
  },
});

updating the propositions:

This API fetches the propositions for the provided DecisionScope list.

Syntax

updatePropositions(decisionScopes: Array<DecisionScope>, xdm?: Map<string, any>, data?: Map<string, any>)

Example

const decisionScopeText = new DecisionScope("{DecisionScope name}");
const decisionScopeImage = new DecisionScope("{DecisionScope name}");
const decisionScopeHtml = new DecisionScope("{DecisionScope name{");
const decisionScopeJson = new DecisionScope("{DecisionScope name}");
const decisionScopes = [
  decisionScopeText,
  decisionScopeImage,
  decisionScopeHtml,
  decisionScopeJson,
];

Optimize.updatePropositions(decisionScopes, null, null);

Public classes

• DecisionScope
• Proposition
• Offer

DecisionScope

This class represents the decision scope which is used to fetch the decision propositions from the Edge decisioning services. The encapsulated scope name can also represent the Base64 encoded JSON string created using the provided activityId, placementId and itemCount.

/**
 * class represents a decision scope used to fetch personalized offers from the Experience Edge network.
 */
module.exports = class DecisionScope {
  name: string;

    name?: string,
    activityId?: string,
