Live queries manage client-side state by exposing a reactive store that normalizes collections and automatically applies optimistic mutations. This enables real-time UI updates and streamlined data access across API sources without manual cache synchronization.

Normalizing API collections for real-time UI updates is best handled by mapping data sources to a reactive store that supports live query subscriptions. This approach uses differential dataflow-based reactivity to ensure the UI updates efficiently when underlying data changes.

Yes, the reactive store integrates seamlessly with TanStack Query to coordinate data fetching and caching. This allows you to combine TanStack Query's server-state management with local collections, live queries, and optimistic mutations for offline support.

To set up a reactive collection and subscribe to live data, create a collection using createCollection and observe its live data using the useLiveQuery hook. This automatically subscribes your UI to differential dataflow-based reactivity for real-time updates.

Yes, you can use optimistic mutations and offline support with a normalized client-side data store. The store applies optimistic mutations automatically and manages collections across API sources, ensuring UI updates happen instantly even when offline.
