Chrome Push Notification: This site has been updated in the background

Question

While implementing the chrome push notification, we were fetching the latest change from our server. While doing so, the service-worker is showing an extra notification with the message

This site has been updated in the background

Already tried with the suggestion posted here https://disqus.com/home/discussion/html5rocks/push_notifications_on_the_open_web/
But could not find anything useful till now. Is there any suggestion ?

question from:https://stackoverflow.com/questions/31108699/chrome-push-notification-this-site-has-been-updated-in-the-background

Answer 1

Generally as soon as you receive a push message from GCM (Google Cloud Messaging) you have to show a push notification in the browser. This is mentioned on the 3rd point in here:

https://developers.google.com/web/updates/2015/03/push-notificatons-on-the-open-web#what-are-the-limitations-of-push-messaging-in-chrome-42

So it might happen that somehow you are skipping the push notification though you got a push message from GCM and you are getting a push notification with some default message like "This site has been updated in the background".
