FAQPage Schema

How do I build a real-time chat application with Convex subscriptions?▼

Build real-time chat applications by using Convex `useQuery` to automatically sync UI updates when backend data changes, ensuring users see new messages instantly without manual refreshes.

What's the best way to implement optimistic UI updates in a Convex app?▼

Implement optimistic updates in Convex by applying instant UI feedback for mutations before server confirmation, ensuring a responsive user experience while maintaining backend data consistency.

How does cursor-based pagination work with Convex usePaginatedQuery?▼

Cursor-based pagination in Convex uses `usePaginatedQuery` to efficiently load large datasets by fetching data in chunks, enabling dynamic interfaces to scale without fetching entire collections.

Can I use Convex for live-updating dashboards and real-time data synchronization?▼

Yes, Convex supports live-updating dashboards through real-time data synchronization, automatically reflecting backend data changes in the UI to provide instant visibility without manual polling.

How do I manage subscription caching behavior in a Convex reactive application?▼

Manage subscription caching in Convex reactive applications by leveraging the framework's built-in data synchronization patterns, which handle cache invalidation and state updates automatically.

When should I use Convex real-time subscriptions instead of manual data fetching?▼

Use Convex real-time subscriptions when building dynamic user interfaces that require instant data changes, such as live dashboards or chat apps, eliminating the need for manual refresh cycles.
