How to send a push notification so that the serviceWorker can process it?

Question

PHP

Good evening! Who is smarter than the menu, tell me how to send a push notification so that the serviceWorker would process it?
The serviceWorker itself works, I register the subscriber, but I can’t figure out how to send notifications themselves ( can’t I do without Google garbage, why can’t I send notifications from my server? )

Answer 1

And how did you write it then, if you don't know how to fix it? In short, when registering a serviceWorker, you make a request to allow pushes, in response you get an endpoint and keys, and data for pushing is sent to this endpoint.
