SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Real-time state synchronization for React components, eliminating boilerplate for subscriptions and ensuring consistent data across the UI.

Core Features & Use Cases

Automatic Subscriptions: useQuery creates real-time subscriptions that update UI automatically.
Smart Caching: Query results are cached and shared across components to reduce redundant requests.
Consistency: All active subscriptions view a consistent snapshot of the database state.
Efficient Updates: Renders update only when relevant data changes to minimize re-renders.
Cursor-Based Pagination: Supports paginated queries with cursor semantics for scalable data loading.

Quick Start

Create a React component that subscribes to a Convex query with useQuery and renders live updates.

FAQPage Schema

How do I set up real-time data synchronization in React components?▼

Real-time data synchronization in React components is automated by using the useQuery hook to create subscriptions that render live updates directly from the database. This eliminates manual subscription boilerplate and ensures consistent UI state.

What is the best way to handle optimistic updates with Convex in a React app?▼

Optimistic updates with Convex are handled automatically alongside useQuery and useMutation hooks to keep the UI consistent. The system ensures all active subscriptions view a consistent snapshot of the database state while minimizing redundant re-renders.

How does cursor-based pagination work for scalable data loading in Convex?▼

Cursor-based pagination in Convex supports paginated queries using cursor semantics for scalable data loading. This allows React components to efficiently load large datasets incrementally without overwhelming the real-time subscriptions.

Does Convex smart caching reduce redundant requests across multiple React components?▼

Convex smart caching automatically caches query results and shares them across multiple React components to reduce redundant requests. This ensures efficient updates by only re-rendering components when the relevant subscribed data actually changes.

When do I need to use useQuery and useMutation hooks for real-time updates?▼

You need to use useQuery and useMutation hooks when adhering to Convex client patterns to automate real-time data subscriptions and mutations. These hooks manage the reactive data flow, requiring the Convex API to synchronize state automatically.
