AWS SQS adapter

AWS SQS adapter

How it works

This adapter uses AWS Simple Queue Service to forward messages between the nodes of a Socket.IO cluster.

Unlike the existing socket.io-sqs package, this package supports binary payloads and dynamic namespaces.

The source code of this adapter can be found here.
