Session.applicationId property

A unique identifier for the current instance of the client-side application.

Signature:

static get applicationId(): Guid;

Remarks

A unique identifier used to correlate logging and other diagnostic information. Its lifetime persists for the duration of the client-side application instance, i.e. it begins with the server request that renders the page, and ends e.g. when the browser tab is closed or F5 is pressed to reload the page. Note that if the application's router supports in-place navigation (via the history.pushState() API), the application session persists across these transitions.
