Extremely easy management of queues with RabbitMQ and/or AmazonSQS

var amqp = require('amqplib')
var AWS = require('aws-sdk')
var when = require('when')
var utils = require('./utils')
var config = require('./config')


var sendWithRabbitMQ = function (sendingData, url, callback) {
  var route = utils.buildRoute(config)

  amqp.connect(route).then(function(conn){
    return when(conn.createChannel().then(function(channel){
      var queue = url;
      var ok = channel.assertQueue(queue, {durable: false});

      return ok.then(function(_qok){
        var dataToSend = JSON.stringify(sendingData);

        channel.sendToQueue(queue, new Buffer(dataToSend));
        channel.close();

        callback(null);
      });
    })).ensure(function() {
      conn.close();
    });
  }).then(null, function (err) {
    callback(err);
  });
};

var sendWithSqs = function (sendingData, url, callback){
  if(typeof sendingData != 'string'){
    sendingData = JSON.stringify(sendingData);
  };
  var params = {
    MessageBody: sendingData,
    QueueUrl: url
  };

  AWS.config.update(config.awsConfigFile);
  var sqs = new AWS.SQS();
  sqs.sendMessage(params, function(err, data){

  });
};

module.exports = sendMessages = function (sendingData, url, callback) {

    ? sendWithRabbitMQ(sendingData, url, callback)
