SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build reactive applications with real-time subscriptions, optimistic updates, caching, and cursor-based pagination.

Core Features & Use Cases

Automatic Subscriptions: useQuery creates a subscription that updates automatically
Smart Caching: Query results are cached and shared across components
Consistency: All subscriptions see a consistent view of the database
Efficient Updates: Only re-renders when relevant data changes
Conditional Queries: Demonstrates conditional use with skip semantics
Mutations with Real-time Updates: Demonstrates how mutations trigger updates

Quick Start

Install Convex Realtime skill and start integrating real-time data streams into your UI.

FAQPage Schema

How do I set up real-time subscriptions in React for live data streams?▼

Real-time subscriptions in React use the useQuery hook to create automatic subscriptions that update UI components whenever database data changes, maintaining a consistent data view across multiple screens.

How does optimistic updates work with real-time mutations in frontend applications?▼

Optimistic updates with real-time mutations allow your frontend to immediately reflect changes while the mutation processes. The subscription automatically syncs the UI once the database confirms the update, ensuring efficient re-renders only when relevant data changes.

Can I implement cursor-based pagination with real-time subscriptions?▼

Yes, you can implement cursor-based pagination with real-time subscriptions. This allows your reactive application to load data incrementally while maintaining automatic updates and a consistent database view across multiple screens.

Does this subscription approach support conditional queries with skip semantics?▼

Yes, conditional queries are supported using skip semantics. This allows your frontend components to conditionally pause or skip real-time data subscriptions when the query parameters are not yet available or required.

How do smart caching and shared query results improve re-renders in reactive apps?▼

Smart caching shares query results across multiple frontend components, ensuring efficient updates by only triggering re-renders when relevant data changes. This prevents unnecessary rendering cycles and maintains data consistency.
