I'm developing web push notification on my website. I follow the Web Push Notifications of Google and The Service Worker Cookbook of Mozilla.
I have tested on the Google Chrome v50+ and everything is working but I will get the error below on Firefox 44, 45, 46, 52, latest Firefox (version 57.0.4 64 bit) when calling navigator.serviceWorker.register('./push-service-worker.js') function.
TypeError: ServiceWorker script at http://localhost:9600/push-service-worker.js for scope http://localhost:9600/ encountered an error during installation.
This is my code:
Register ServiceWorker in controller.js
navigator.serviceWorker.register('push-service-worker.js')
.then((registration) => {
return registration.pushManager.getSubscription()
.then((subscription) => {
if (subscription) {
return subscription;
}
var subscribeOptions = {
userVisibleOnly: true,
applicationServerKey: buildApplicationServerKey(),
};
return registration.pushManager.subscribe(subscribeOptions);
});
})
.then((subscription) => {
sendSubscriptionToServer(subscription);
})
.catch((err) => {
console.log('Unable to subscribe to push: ', err);
});
push-service-worker.js
'use strict';
self.addEventListener('push', (event) => {
var payload = event.data.json();
var title = payload.title || 'Title';
event.waitUntil(
self.registration.showNotification(title, {
body: payload.body,
icon: './common/images/notification-icon-192x192.png',
image: payload.image || '',
})
);
});
self.addEventListener('notificationclick', (event) => {
event.notification.close();
var urlToOpen = new URL('/', self.location.origin).href;
event.waitUntil(
clients.matchAll({
type: 'window',
includeUncontrolled: true,
})
.then((windowClients) => {
var matchingClient = null;
for (var i = 0; i < windowClients.length; i++) {
var windowClient = windowClients[i];
if (windowClient.url === urlToOpen) {
matchingClient = windowClient;
break;
}
}
if (matchingClient) {
return matchingClient.focus();
} else {
return clients.openWindow(urlToOpen);
}
})
);
});

Thank for helping!
