Hi I am new to ionic and learning it for past 3-4 weeks. I am working on a news discussion app and looking for a solution which will
1) allow user authentication
2) sync between offline and online data (articles, comments etc). User can read articles offline and If a user post comment when he is offline then it should get posted when he is online.
I read that PouchDB is the right choice. Is there any other services which allows for sync between offline and online data. Can Backand and Firebase manage the sync.
