metabroker v0.1.1

Simple publish-subscribe API for several message brokers: Redis, RabbitMQ (AMQP), ActiveMQ (STOMP).

Application can utilize unified pub-sub interface and easily switch from one broker to another.

Actual modules implementing protocols are:

• redis
• amqp-connection-manager which itself is a wrapper for amqplib
• stomp-client

Module automatically reconnects and resubscribes in case of broker failure.

Installation

npm install metabroker

Example

const metabroker = require('metabroker')
let url = 'redis://10.192.171.251:6379'
const broker = metabroker.connect(url, () => {
  console.log('connected', url)
})
broker.subscribe('test_queue', message => {
  console.log('received:', message)
})
setInterval(() => {
  broker.publish('test_queue', new Date())
}, 1000)
