SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires convex, react, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the challenge of building reactive applications with real-time data synchronization, optimistic updates, and efficient caching.

Core Features & Use Cases

  • Real-time Subscriptions: Automatically update components when data changes.
  • Optimistic Updates: Display changes immediately before server confirmation.
  • Smart Caching: Cache query results and share them across components.
  • Cursor-based Pagination: Efficiently load paginated data with cursors.
  • Use Case: Develop a chat application that updates in real-time as users send messages.

Quick Start

Use the convex-realtime skill to fetch and display real-time task updates for a specific user.

Frequently Asked Questions about convex-realtime

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

FAQPage Schema
How do I implement real-time subscriptions in React using Convex?▼

Real-time subscriptions in React using Convex automatically update components when backend data changes. This skill manages subscription lifecycle and syncs query results reactively without manual polling.

Can I display optimistic updates immediately before the server confirms changes?▼

Yes, optimistic updates display changes immediately before server confirmation. This skill handles the rollback logic if the mutation fails, ensuring the UI stays responsive during data synchronization.

What's the best way to handle cursor-based pagination for real-time data?▼

Cursor-based pagination efficiently loads real-time data by tracking position rather than offsets. This skill manages cursor state and fetches subsequent pages while maintaining active subscription streams.

How does caching work with shared query results across multiple React components?▼

Caching shares query results across multiple React components to prevent redundant fetches. This skill manages cache behavior by storing Convex query outputs and synchronizing them when underlying data mutates.

Do I need both Convex and React to build reactive apps with this approach?▼

Yes, this implementation requires both Convex and React. Convex provides the real-time backend infrastructure, while React manages the reactive component rendering and subscription lifecycle.

Why use Convex for real-time data synchronization instead of manual polling?▼

Convex real-time data synchronization pushes updates instantly when data changes, eliminating manual polling delays. This approach ensures components reflect the latest database state automatically via active subscriptions.
