# mqu

```bash

npm i mqu

```

## Example

```js

const mqu = require('mqu')('amqp://guest:guest@localhost:5672')

mqu.on('error', error => {

  console.error('oh my, error!!', error)

  process.kill(process.pid)

})

mqu.on('connect',  () => {

  console.error('connect method succeeded')

})

mqu.consumeJob('j', data => console.log('worker 1', data))

mqu.consumeJob('j', data => console.log('worker 2', data))

mqu.consumeEvent('e', data => console.log('\thandler 1', data))

mqu.consumeEvent('e', data => console.log('\thandler 2', data))

mqu.consumeEvent('e', data => console.log('\thandler 3', data))

const jobInterval = setInterval(() => {

  const job = new Date().toISOString() + '-job'

  mqu.publishJob('j', job).then(() => console.log('published job', job))

}, 2000)

const eventInterval = setInterval(() => {

  const ev = new Date().toISOString() + '-event'

  mqu.publishEvent('e', ev).then(() => console.log('published event', ev))

}, 1500)

process.on('SIGINT', () => {

  clearInterval(jobInterval)

  clearInterval(eventInterval)

  mqu.close().then(() => console.log('closed!'))

})

```

## Events

- `error` - emitted when transport, protocol or consumer error is occurred 

- `connect` - emitted when a protocol level connection is ready

## Why?

Because best [RabbitMQ](https://www.rabbitmq.com/) client for [node.js](https://nodejs.org) [bramqp](https://github.com/bakkerthehacker/bramqp) is too verbose to be used directly for:

- round robin distribution of jobs between workers

- fanout distribution of events to listeners
