storageReactNative

Way data is stored for this database For a Node.js/Node Webkit database it's the file system For a browser-side database it's localforage, which uses the best backend available (IndexedDB then WebSQL then localStorage) For a react-native database, we use @react-native-async-storage/async-storage

This version is the react-native version
