SDK Events (Node.js)

Description

When initializing the SDK, the options.events object is an optional object with event name keys and callback function values. It can be used to subscribe to various events that occur within the SDK. For instance the clientReady event may be used with a callback function that will be invoked when the SDK is ready for method calls.

When the callback function is called, an event object is passed in. Each event has a type corresponding to the event name. Some events include additional properties with pertinent information.

Node.js

const targetClient = TargetClient.create({
    client: "acmeclient",
    organizationId: "1234567890@AdobeOrg",
    decisioningMethod: "on-device",
    events: {
        clientReady: onTargetClientReady,
        artifactDownloadSucceeded: onArtifactDownloadSucceeded,
        artifactDownloadFailed: onArtifactDownloadFailed
    }
});

function onTargetClientReady() {
    // make getOffers requests
    targetClient.getOffers({...})
}

function onArtifactDownloadSucceeded(event) {
    console.log(`The artifact was successfully downloaded from '${event.artifactLocation}'`);
    // optionally do something with event.artifactPayload, like persist it
}

function onArtifactDownloadFailed(event) {
    console.log(`The artifact failed to download from '${event.artifactLocation}' with the following error message: ${event.error.message}`);
}
