Communication between asp.net app and a serviceworker, via signalR?
<p>I'm new to serviceworkers and I wonder how could I connect my serviceworker to my asp.net application. My js client already is communicated with a service worker and it's able to show notifications.
However, I've seen that some webs (e.g facebook) send notifications even the browser's tab ins't opened (not inactive, not opened). I use signalR to communicate my app with the server. Would it be possible to communicate the serviceworker with the server? It would require to add signalR code to the serviceworker if I'm not wrong, but I don't think it's possible. I've seen that google has another way of communication, <a href="https://developers.google.com/web/updates/2015/03/push-notifications-on-the-open-web" rel="noreferrer">Google Cloud Communication</a></p>

<p>I can't use that, so any ideas of how could I solve this problem?</p>
