[paho-dev] Minified version of Javascript client is broken

[James Sutton1 <james.sutton@xxxxxxxxxx>]

Hi,

The _javascript_ client seems to be broken
when minified, I've raised a bug here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=469700,
but thought I would pop it on the mailing list as well.

It seems that the YUI Compressor is
not renaming the Message getters and setters correctly during compression:

Non- Compressed:

get payloadBytes() { return this._getPayloadBytes();
},

YUI Compressed:

get payloadBytesfunction() {
         
  return this._getPayloadBytes()
},

I've tried compressing using Google
Closure and JSmin and they seem to compress correctly.

Closure Compressed:

get payloadBytes() {
         
  return this._getPayloadBytes()
},

JSmin Compressed:

get payloadBytes() {
         
  return this._getPayloadBytes();
},

Because of this, when you try to publish a message,
the following error is shown:

Uncaught TypeError: Cannot read
property 'byteLength' of undefined mqttws31-min.js:15
 Paho.MQTT.q.encode mqttws31-min.js:15
 Paho.MQTT.v._socket_send mqttws31-min.js:15
 Paho.MQTT.v._process_queue mqttws31-min.js:15
 Paho.MQTT.v._schedule_message mqttws31-min.js:15
 Paho.MQTT.v.send mqttws31-min.js:15
 Paho.MQTT.p.send mqttws31-min.js:15
 
 
Because it has been renamed to payloadBytesFunction, it does not work when
the following code is executed:

var F = this.payloadMessage.payloadBytes;
K += F.byteLength;

Is changing the maven build to use closure or JSMin
the best solution? Or is there something better we could do?
