graphql-amqp-subscriptions

Implements the PubSubEngine interface from graphql-subscriptions using AMQP (RabbitMQ) as the pub/sub mechanism. Current stable version is 3.0.1, targeting graphql@16.x and graphql-subscriptions@3.x. Maintained since 2017 with periodic updates. Key differentiator vs alternatives like graphql-redis-subscriptions: it reuses existing amqplib connections and channels, offers flexible exchange/queue configuration, and supports topic exchanges for pattern-based routing.
