Can’t find serviceWorker in navigator anymore

since the new update of Google Chrome (version 69.0.3497.92 (official build) (64-bit)) I can’t find the serviceWorker service in the Navigator anymore. Actually I could register my Service Worker as follows but now I get an error that serviceWorker cannot be found in the navigator:

if('serviceWorker' in navigator) {
    * Register the Service Worker
    * */
    navigator.serviceWorker.register('sw.js').then(function(registration) {
        console.log('Service Worker Registered');
} else console.log('Your browser does not support the Service-Worker!');

How can I now use the Service Worker again, or how can I get it to run again for all Chrome versions?


Serve your page over HTTPS or use localhost. Service workers require a Secure Context.

(MDN page, Chromium page).

The value of window.isSecureContext indicates whether [SecureContext] features are visible or hidden. (This is true on a file:// URL and the serviceWorker API will be visible, but it won’t work, of course.)
