Constructive Realtime

Real-time data delivery via GraphQL subscriptions, live queries, and change tracking.

When to Apply

Use this skill when:

• Adding real-time subscriptions to a Constructive app
• Working with PostGraphile live queries
• Implementing change tracking and notifications
• Using WebSocket connections for real-time updates
• Using ephemeral realtime for high-frequency signals (cursors, presence, live indicators)

Core Concepts

GraphQL Subscriptions

PostGraphile v5 provides built-in subscription support via WebSocket (graphql-ws protocol). Subscriptions are automatically generated for any table with appropriate grants.
