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.

npm install graphql-ws
