Adding authenticated user ID information in server-side NodeJS Application Insights events

Question

I have a NodeJS app in which I'm consuming the applicationinsights NodeJS package (this). According to ApplicationInsights data model described here, it says the property exists, but I am not able to find a code snipped as to how to set this property in the telemetry event I'm sending.

Any snipped describing how to do this would be helpful!

According to your description, I only found the tutorials for ASP.NET about Setting the user context in an ITelemetryInitializer and Authenticated users for JavaScript.

Then I checked the setAuthenticatedUserContext method under User.ts of Microsoft Application Insights SDK for JavaScript and found the related code snippet under TelemetryContext.ts as follows:

if (typeof userContext.authenticatedId === "string") {
      envelope.tags[tagKeys.userAuthUserId] = userContext.authenticatedId;
}

Then checked ContextTagKeys.ts and found the context tags as follows:

this.sessionId = "ai.session.id";
this.userAccountId = "ai.user.accountId";
this.userId = "ai.user.id";
this.userAuthUserId = "ai.user.authUserId";
...

but I am not able to find a code snipped as to how to set this property in the telemetry event I'm sending.

For NodeJS SDK, the context tag keys are under ContextTagKeys.ts. For your requirement, you could leverage the following code snippet:

appInsights.defaultClient.context.tags[appInsights.defaultClient.context.keys.userAuthUserId] ="xxxx";

For Session id, Account id or other context fields, you just need to choose the relevant context tag key.
