graphql-ably-pubsub

GraphQL Ably PubSub is a PubSubEngine implementation for Apollo Server that uses Ably as the message transport for GraphQL subscriptions. It enables real-time data updates through subscriptions without requiring developers to maintain their own WebSocket infrastructure, leveraging Ably's scalable, globally distributed platform.

Key Features

• Ably Integration — Uses Ably's WebSocket infrastructure as the transport layer for GraphQL subscriptions, providing high availability and scalability.
• Apollo Server Compatibility — Implements the PubSubEngine base-class to seamlessly integrate with Apollo Server's subscription system.
• Production-Ready Pub/Sub — Replaces Apollo's default PubSub implementation, which is not recommended for production, with a robust, managed solution.
• Real-Time Updates — Allows GraphQL mutations to publish updates and clients to subscribe to those updates in real-time through subscription queries.
• Easy Configuration — Supports all Ably JS SDK configuration options, including API key management via environment variables.

Philosophy

This project simplifies building real-time GraphQL applications by offloading WebSocket management to Ably's infrastructure, allowing developers to focus on application logic rather than infrastructure maintenance.
