##About ####Mosca is a node.js mqtt broker, which can be used:

• Standalone
• Embedded in another Node.js application

Mosca officially support only node v0.10 but v0.11.x should work too. Node v0.8 is not supported.

• MQTT 3.1 compliant.
• QoS 0 and QoS 1.
• Various storage options for QoS 1 offline packets, and subscriptions.
• As fast as it is possible.
• Usable inside ANY other node.js app.

##Quickstart Show me some code:

var mosca = require('mosca')

var ascoltatore = {
  //using ascoltatore
  type: 'mongo',        
  url: 'mongodb://localhost:27017/mqtt',
  pubsubCollection: 'ascoltatori',
  mongo: {}
};

var settings = {
  port: 1883,
  backend: ascoltatore
};


server.on('clientConnected', function(client) {
    console.log('client connected', client.id);     
});

// fired when a message is received
server.on('published', function(packet, client) {
  console.log('Published', packet.payload);
});

var server = new mosca.Server(settings);
server.on('ready', setup);

// fired when the mqtt server is ready
function setup() {
  console.log('Mosca server is up and running')
}
