IONIC 3 + Firebase + REST API?

Hi All,

I am developing an hybrid application using IONIC - 3.

Requirement :

  1. Application should able to work Offline (Read Only , No Write)
  2. Application should be able to write to Server , when online.
  3. Application should read from local data store.
  4. RealTime Data Sync is Not require here.

i’m thinking to use Firebase as local datastore & for online we have REST API’ s(given by Customer)

Kindly suggest How to use Firebase as local datastore without having any push mechanism to Firebase Cloud .
