Design offline-first mobile applications that provide seamless user experience regardless of connectivity.
Minimal working example:
import AsyncStorage from '@react-native-async-storage/async-storage';
import NetInfo from '@react-native-community/netinfo';
class StorageManager {
static async saveItems(items) {
try {
await AsyncStorage.setItem(
'items_cache',
JSON.stringify({ data: items, timestamp: Date.now() })
);
} catch (error) {
console.error('Failed to save items:', error);
}
}
static async getItems() {
try {
const data = await AsyncStorage.getItem('items_cache');
return data ? JSON.parse(data) : null;
} catch (error) {
console.error('Failed to retrieve items:', error);
return null;
}
}
