For persistent storage in React Native the options are: AsyncStorage: The easiest way to store objects, provides Key-value based asynchronous APIs to store data. Only provides basic get-put APIs, not suitable for search queries. IndexedDB Table with Indexes. By default our keyPath (and thusly main table) is indexed by id. We built some single key indexes and one compound key index which makes our data access a breeze! We can use this compound index to filter our data down by each of our keys, but in that specific order. For instance, we search for a specific Bucket first: You might use IndexedDB to store structured data that’s unrelated to any data on the server. An example might be a calendar, a to-do list, or saved games that are played locally. In this case, the application is really a local one, and your web site is just the vehicle for delivering it.

It's really not different than, say, Facebook consuming their API. IndexedDB Table with Indexes. By default our keyPath (and thusly main table) is indexed by id.
