How to receive push notification with closed pwa

[Tharles Ribeiro Pereira]

Hi all! Is there any way to receive the notification with the pwa closed? using service-worker.

I have a project, where the service-worker is registered, the user already receives notifications from the push notifications api, but when the pwa is closed, the notifications no longer reach the user, and if he enters the pwa, he will receive the delayed notifications.

I wanted someone's help, and if it is possible to do with the site or pwa closed.

I don't know, using 'sync'

This sounds more like a Web development question, rather than a Chromium development (working on the browser itself) question.

This does touch on Chromium development a bit because there are constraints on how the Push API works that are dictated by the browser implementation. In Chrome on Windows, macOS and Linux a Service Worker will only be launched to handle a push event if the browser is running. This means that if the user closes an installed web app and that was the last open browser window then the browser will exit and not be able to receive push notifications. This isn't an issue on Android (because push notifications are delivered via the OS and will launch the browser to handle them) or on ChromeOS (where the browser never exits).

Running a persistent background service to handle push notifications has been investigated but my understanding is that there are a number of complexities which have prevented that solution from being implemented.
