remove_mqtt_retained_msgs.md

var mqtt    = require('mqtt');
var lodash = require('lodash');
var client  = mqtt.connect({ host: 'localhost', port: 1883 });

client.on('connect', function () {
  console.log('Connected')
  client.subscribe('presence');
});


client.on('message', function (topic, message) {
  // message is Buffer
  console.log(message.toString());
  
  // remove the retained message
  client.publish('presence', undefined, {retain: true});
});

Thanks man, this saved me!
