Yes, React Native does support offline database storage. React Native uses the AsyncStorage
API to provide built-in support for storing data offline.
AsyncStorage
is a simple, asynchronous, key-value storage system that allows you to persist data locally on the user’s device. It provides basic CRUD (Create, Read, Update, Delete) operations for managing data, such as storing, retrieving, updating, and deleting data.
To use AsyncStorage
in your React Native app, you can import it from the react-native
package like this:
import { AsyncStorage } from 'react-native';
Once imported, you can use the getItem
, setItem
, removeItem
, and clear
methods to interact with the local storage.
Here are the basic steps to store and retrieve data using AsyncStorage
:
- Import the
AsyncStorage
module. - Use the
setItem
method to store data by providing a key-value pair. - Use the
getItem
method to retrieve data by providing the key.
In addition to AsyncStorage
, you can also use third-party libraries like SQLite
or Realm
for more advanced offline database storage in React Native.
