SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps developers build reactive frontends by providing real-time data subscriptions, optimistic updates, and intelligent caching to keep UI in sync with the backend.

Core Features & Use Cases

Real-time subscriptions that automatically update UI components as data changes.
Optimistic updates to improve perceived performance without waiting for server confirmation.
Cursor-based pagination and smart caching to reduce network requests and accelerate data access.
Use Case: Build a live task dashboard where lists refresh as users modify data, while UI stays consistent across components.

Quick Start

Install and configure Convex's realtime client, import the API types, and start subscribing to data streams in your React components to see live updates.

FAQPage Schema

How do I set up real-time subscriptions in React with Convex?▼

Real-time subscriptions in React are set up by installing the Convex client, importing API types, and subscribing to data streams so UI components automatically update as backend data changes.

How do optimistic updates work with Convex real-time data?▼

Optimistic updates with Convex improve perceived performance by applying UI changes immediately without waiting for server confirmation, keeping the frontend reactive while maintaining eventual consistency with backend data.

What is the best way to implement cursor-based pagination for live data in React?▼

Cursor-based pagination for live React data is handled through Convex real-time subscriptions combined with smart caching, reducing network requests while keeping paginated lists synchronized with backend changes.

Can I keep UI state consistent across multiple React components using Convex?▼

Convex real-time subscriptions keep UI state consistent across multiple React components by automatically propagating data changes, ensuring all connected components reflect the same backend state without external state management tooling.

Do I need external state management libraries to build reactive frontends with Convex?▼

No external state management tooling is required to build reactive frontends with Convex, as real-time subscriptions, optimistic updates, and smart caching handle data synchronization and consistent state across components natively.
