 If your application runs in the Node.js, install the [`"@microsoft/feature-management-applicationinsights-node"`](https://www.npmjs.com/package/@microsoft/feature-management-applicationinsights-node) package. The following example shows how you can create a built-in Application Insights telemetry publisher and register it to the feature manager.
 
 ```typescript
-import appInsights from "applicationinsights"
-import { createTelemetryPublisher, trackEvent } from "@microsoft/feature-management-applicationinsights-node"
+const appInsights = require("applicationinsights");
+appInsights.setup(process.env.APPINSIGHTS_CONNECTION_STRING).start();
+
+const { FeatureManager, ConfigurationObjectFeatureFlagProvider } = require("@microsoft/feature-management");
+const { createTelemetryPublisher, trackEvent } = require("@microsoft/feature-management-applicationinsights-node");
 
-appInsights.setup().start(); // for more information: https://learn.microsoft.com/azure/azure-monitor/app/nodejs#basic-usage
+const publishTelemetry = createTelemetryPublisher(appInsights.defaultClient);
+const provider = new ConfigurationObjectFeatureFlagProvider(jsonObject);
+const featureManager = new FeatureManager(provider, {onFeatureEvaluated: publishTelemetry});
