How to determine where a function is invoked?

Question

Like in which hook of the component the function was called ?

I need to assert that a function in my mixin is invoked only in the didInsertElement() hook and not before, so that the function could handle the DOM.

You mean for testing or in production? – Lux Jan 07 '19 at 19:04 — Lux, Jan 07 '19 at 19:04

You could check if this.element is in the dom like document.contains(this.element).

I have created a twiddle, this details you how to check if a function is called directly from didInsertElement. (This method uses error stack)
