QUESTION
I'll have an angular service with a function getTimeLinePosts
to get JSON from a server. In the timeline-page.ts component I'll subscribe to that function. When sending a request to the server I'll need to send the date of the previous cached response (using ionic cache) to check if there is new data. The problem is the const date
returns a promise instead of a value. I'll can't use async getTimeLinePosts

?

OK I researched and finally made it work on my Ionic 3 PWA, so I am posting solution here:
- Prerequisites:
- I created ionic blank app (just a home page)
- installed angularfire2 and firebase ("angularfire2": "5.0.0-rc.4","firebase": "4.9.1") using npm install, I used specifically 5.0.0-rc.4" cause I had stability issues with latest one;(
- created config (filename environment.ts in src folder):

One of cache key declaration:

Can you tell me a proper design for this? Do I need to create a class for this and use that class in other places where it needs or any other way? Hope you'll give feedback for this.
