This is more of an architecture/stack question that anything.

A simple study time tracker - The app should need a connection at first to create an account or sign in, But once they do so it should be fully offline

  • The app should require a connection to create an account and sign in
  • After that everything should be stored locally and be accessed that way
  • This local data should update a database on a server periodically (every day at 12am or something)

So my question is - What should i use to store and persist state in react native and what can i use to have this data synced to a database at certain intervals?

First, to save data locally, you can check out this answer which mention specifically this.

Saving data locally you should set an attribute to track if this data is sync or not, ( e.g _synced: false )

Now, to make syncs happening you shouldn't rely on a specific daily hour to do it, as if the user lost his connection in that hour, the app wouldn't sync its data.

Take a deep read into this react-sync-adapter extension that syncs your app's data based on a timeout, you can change this sync to be foreground and background.

Using this, you create a function to be executed every x seconds, then in this function you'd get all the non-synced data ( _synced === false ) and after syncing it set this data to true. This way the next sync's will be smoother
