This article describes how to track when an Angular application's iFrame containing a PHP project reloads.

The use of event listeners, DOM observation via the MutationObserver API, and network monitoring via XMLHttpRequest are some of the techniques investigated.

It can be difficult to identify changes within an iframe in an Angular project, particularly if you don't have access to the PHP code. Using JavaScript methods such as the postMessage API, inserted scripts to track HTTP requests, and the load event, developers may efficiently show a loading spinner and monitor iframe reloads.
