Real-Time Subscriptions with useSubscription
WebSocket link setup, useSubscription(), merging subscription data into reactive state.
Real-Time With Subscriptions
GraphQL subscriptions push data from server to client over a persistent connection. Where queries pull once, subscriptions stream updates — perfect for chat, live feeds, and notifications.
WebSocket Transport
Subscriptions need a long-lived connection, so they use WebSockets instead of HTTP. The graphql-ws library provides the modern protocol via GraphQLWsLink.
