 Here is an example of how to structure a non trivial application with VUEX broken into modules:

+- Serviceworker push notifications
+  - INITIAL THINKING: avoid it for now until the dust settles, rely on email notification or other established means for now and in app popups perhaps as well
+    - This is also part of service workers api but is radically different than above as it's to do with integrating device notifications with web servers.
+		- requires permission, works with browser closed, messages go from server to intermediary such as google or microsoft or apple who then push it to the device.
+    - User can block and say no and then app can never after that re-request push notifications (as far as I can tell, maybe there's a workaround but not sure)
+    - It's main advantage is browser can be closed but still receive timely messages (i.e. new mail in rockfish would be an ideal use-case)
+    - Alternatives would be user must stay in web page to get notified via polling like how rockfish works now for mail.
+    - If I enable notifications via email then it kind of roundabout covers this use-case
+    - as of now 2018-10-22 15:23:49 iOS Safari (mobile apple devices browser) does not support push notifications, only dekstop Macs and you need to jump through many hoops to get approval
+      - This means basically that it would be a pain in the ass for apple devices but easier for others.  Hmmm...
