ServiceWorker fetch failed (ERR_NAME_NOT_RESOLVED)

See original GitHub issue

Installing serviceworker using following code fails with ERR_NAME_NOT_RESOLVED I am able to load sw.js file using ajax and via script tag just fine

navigator.serviceWorker.register('sw.js').then(function(registration) {
  console.log('ServiceWorker registration successful with scope: ', registration.scope);
}, function(err) {
  console.log('ServiceWorker registration failed: ', err);
});

The result is

An unknown error occurred when fetching the script.
Failed to load resource: net::ERR_NAME_NOT_RESOLVED
ServiceWorker registration failed:  TypeError: Failed to register a ServiceWorker: An unknown error occurred when fetching the script.

Got it, thanks for confirming. We would want to make sure any web content loads in Carlo, so your SW request stands as a bug report.

Web Push support (GCM) from Service Worker pushManager would be great as electron doesn’t support it: https://github.com/electron/electron/issues/6697
