🎯 Popular Use Cases¶

Real-time Chat Applications¶

Build WhatsApp-like chat apps with typing indicators, presence status, and message synchronization.

// Subscribe to real-time messages
LDK.collection('messages').subscribeToUpdates().listen((event) {
  if (event.type == CollectionEventType.created) {
    _addMessage(Message.fromJson(event.data));
  }
});

Offline-First Mobile Apps¶

Create apps that work seamlessly offline with automatic data synchronization.

// Optimistic updates work offline
await LDK.collection('posts').create(
  {'title': 'New Post', 'content': 'Content'},
  optimistic: true, // Updates UI immediately
);

E-commerce Applications¶

Build shopping carts with real-time inventory updates and offline order queuing.

// Real-time inventory updates
LDK.collection('products').subscribeToEntry(productId).listen((event) {
  _updateProductStock(Product.fromJson(event.data));
});
