I'm not sure whether this will work in this gateway checker, since it relies on service-worker to work, and only work in client-side which supports sw.

Cool project! Could you check locally if it works with your app before we merge?

Oh, no, directly fetch() my gateway only resulted in 404. Normally, this 404 page carries a service worker, who will redirect the browser to the actual content on IPFS.

But fetch() won't execute the service worker, so it won't work with this checker, sadly.

now it is also requesting a script file, which actually executes code ... not sure if it is enough, your project seems cool ... verify it again if you can
