I am looking for advice or documentation on the best practices for react native's async-storage.
Two specific questions I have are:
The data I would be setting/ getting daily is minimal if that matters at all. I would prefer to not use the DB as it can cut down on costs.
If the data you're setting does not need to be persisted beyond the app, then there really is no problem with getting and setting once a day. would definitely save you costs on using a database for just that.
And no, I don't think it ever expires.
