Hey push notifications are independent of what framework/library you use. The vanilla way will always boil down to something like this

Notification.requestPermission(function(status) {
    console.log('Status ', status);
});

But because building the whole push notifications infrastructure ourselves is tedious. Its better to use services like onesignal. Which is fre for both mobile and Web.

Here are their getting started guides. That might help you. documentation.onesignal.com/docs/web-push-overview
