- [Instructor] Any website that you are visiting…can actually be installing and registering a service worker.…So, how can you see all the current registered…and installed service workers?…If you're using Chrome on desktop or on Android,…you can go to a special URL.…It's chrome://serviceworker-internals.…When you get there, you will see all the service workers…that are currently installed in your system.…
For example I have one service worker here…for the scope code nasa, I can see the registration ID,…some information about that service worker,…for example it's currently activated,…remember activated doesn't mean that it's currently running,…because it's currently stopped,…we can see what happens if I open…a new window inside Chrome,…and we go to code.nasa.gov.…So basically, this same scope.…It can also be any URL, not just code.nasa.gov…it can be even nonexistent pages, like 404 pages.…
So anything in that scope…will be managed by the service worker.…So if I now go there,…you can see that it's currently running.…
