deprecated mqtt.createClient function

[hmueller01]

I am new to homA and just installed this and node.js on a RPi running jessie. After npm install and running demo I got an error message: self.mqttClient = mqtt.createClient(port || params.brokerPort, host || params.brokerHost, extraParameters); TypeError: mqtt.createClient is not a function Google helped:

createClient() has been deprecated by mqtt module, use connect() instead.

Installed versions:

> node_modules/mqtt/mqtt.js version
MQTT.js version: 2.4.0

So, I patched homa.js like this:

I do not know what extraParameters is for and how it should be used in url object context. Right now it works so far ...

I got news. extraParameters is needed, if you like to pass a username and password. I changed the connect call to mqtt.connect(brokerUrl, extraParameters) The homa connect call looks like this:

var options = {
  username: "xxx",
  password: "xxx"
};
homa.mqttHelper.connect(null, null, options);

I update the code. Where do we need to upload homa.js that npm install downloads this new version?

@binarybucks Can you please upload the updated homa.js. Thanks. Holger
