Live update after publishing in the appstore/playstore

Hello everyone, I’m here because I’m developing an app that have a “News” section, I want to know how can I update the content lively, after the publication in the stores.

Is the live update from ionic still working after the publication?

I should use a database?

Wow, no answer. Probably you already figure out but for other persons:

You can check the “news” on your server and store locally just with localStorage. If you need a more powerful (and permanent) storage you can check database solutions like PouchDB (although) PouchDB is more for sync data.
