Node-queue is a node.js module for multiple databases. It can be very useful if you work with (d)ddd, cqrs, eventsourcing, commands and events, etc.

Currently these databases are supported:
- inmemory
 - mongodb (node-mongodb-native)
 - couchdb (cradle)
 - tingodb (tingodb)
 - redis (redis)
 
看起来挺不错的样子
