# Microsoft Feature Management Application Insights Plugin for Node

Feature Management Application Insights Plugin for Node provides a solution for sending feature flag evaluation telemetry produced by the [`@microsoft/feature-management`](https://www.npmjs.com/package/@microsoft/feature-management) library.

## Getting Started

For more information, please go to [Feature reference](https://learn.microsoft.com/azure/azure-app-configuration/feature-management-javascript-reference#application-insights-integration).

### Prerequisites

- Node.js LTS version
- `applicationinsights` SDK 2.x (classic)

### Usage

``` javascript
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");

const publishTelemetry = createTelemetryPublisher(appInsights.defaultClient);
const provider = new ConfigurationObjectFeatureFlagProvider(jsonObject);
const featureManager = new FeatureManager(provider, {onFeatureEvaluated: publishTelemetry});

// FeatureEvaluation event will be emitted when a feature flag is evaluated
featureManager.getVariant("TestFeature", {userId : "<TARGETING_ID>"}).then((variant) => { /* do something*/ });

// Emit a custom event with targeting id attached.
trackEvent(appInsights.defaultClient, "<TARGETING_ID>", {name: "TestEvent",  properties: {"Tag": "Some Value"}});
