I am using files by cdn, but apparently my service worker does not cache them. Would you do it?

Service worker code:

const version = "0.0.1";
const cacheName = `sfa-$version`;
self.addEventListener('install', e => 
 e.waitUntil(
 caches.open(cacheName).then(cache => 
 return cache.addAll([
 `/`,
 `/dashboard/`
 ])
 .then(() => self.skipWaiting());
 )
 );
);

self.addEventListener('activate', event => 
 event.waitUntil(self.clients.claim());
);

self.addEventListener('fetch', event => 
 event.respondWith(
 caches.open(cacheName)
 .then(cache => cache.match(event.request, ignoreSearch: true))
 .then(response => )
 );
);

Perhaps you tried to set the onerror handler on the navigator.serviceWorker container like this:

// no effect outside service worker script
navigator.serviceWorker.onerror = function() ...;

The error handler must be set from within a service worker script with self.onerror (self is a special variable/attribute here that refers to ServiceWorkerGlobalScope). The onerror callback is only provided an error message.

// inside service worker script
self.onerror = function(message) 
 console.log(message);
;

Alternatively, you could listen to the service worker's error event, which includes an ErrorEvent containing the location of the error:

// inside service worker script
self.addEventListener('error', function(e) 
 console.log(e.filename, e.lineno, e.colno, e.message);
);
