Trigger an action when document.cookie changes?

Question

I need to update localStorage when document.cookie changes. Is there any way to set a listener, overwrite a prototype to act as middleware or some other pattern that would result in the ability to trigger a function on change? I'm trying to avoid something like polling on an interval.

Thanks for any ideas.

Answer 1

Theres no avoiding it, these events simply dont exist, you'll need to poll.
