A small TypeScript library that implements GraphQL subscriptions by wiring a PubSub system (e.g., EventEmitter or Redis) into GraphQL resolvers. It works with any GraphQL server and client, and requires a network transport like subscriptions-transport-ws.

Use cases

• implement real-time GraphQL subscriptions in Node.js
• publish events to GraphQL subscription resolvers via a pubsub system
• back GraphQL subscriptions with Redis or another EventEmitter-based pubsub
• add live data updates to a GraphQL API
• create typed pubsub events for GraphQL subscriptions

When to choose

• you need real-time push updates over GraphQL subscriptions
• you want a transport-agnostic pubsub layer that works with any GraphQL server
• you want a lightweight, well-maintained library from the Apollo ecosystem

When to avoid

• you need a full subscription server or WebSocket transport (use subscriptions-transport-ws or graphql-ws alongside it)
• your project does not use GraphQL
• you need client-side subscription handling rather than server-side publishing
