FAQPage Schema

How do I add realtime subscriptions to a React application using Convex?▼

Realtime subscriptions in React using Convex are enabled via the useQuery hook, which automatically wires components to the API and refreshes the UI when underlying data changes. It maintains a shared cache and consistency guarantees across the application.

How do optimistic updates work with Convex mutations in React?▼

Optimistic updates in Convex allow the UI to reflect mutation changes immediately. If the mutation fails, the updates automatically rollback to ensure data consistency and improve perceived performance for interactive dashboards or task boards.

Does Convex support realtime pagination for live data dashboards?▼

Convex supports realtime cursor-based pagination for React dashboards and collaboration tools. This allows components to load live data incrementally while maintaining a shared cache and automatic UI refreshes.

Can I use Convex realtime queries for a collaborative task board?▼

Convex realtime queries are designed for collaborative task boards and dashboards. They provide live data synchronization, shared component state, and optional optimistic mutation updates that rollback on error.

What happens to the shared React cache when a Convex realtime update fails?▼

When a Convex realtime mutation fails, the system automatically rolls back any optimistic updates. This ensures the shared component cache maintains consistency guarantees and prevents stale or invalid data from persisting in the UI.
