SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides developers with the patterns and examples needed to build highly reactive applications using Convex's real-time data capabilities, ensuring data consistency and efficient updates.

Core Features & Use Cases

  • Real-time Subscriptions: Automatically update UI when data changes using useQuery.
  • Optimistic Updates: Provide instant UI feedback for mutations before server confirmation.
  • Cursor-Based Pagination: Efficiently load large datasets with usePaginatedQuery.
  • Use Case: Building a live-updating dashboard or a chat application where users see new messages and data changes instantly without manual refreshes.

Quick Start

Refer to the provided code examples to implement real-time subscriptions and mutations in your Convex application.

Frequently Asked Questions about convex-realtime

High-intent search queries and answers about installing and using this skill.

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.
