I'm trying to start playing with node and mqtt and I found this really nice library for the MQTT protocol that integrates it to node.js. The library is simply called mqttjs: https://npmjs.org/package/mqttjs
I've walked through setting up node js according to this simple guide: http://shapeshed.com/setting-up-nodejs-and-npm-on-mac-osx/ and the server created and launched in that example works fine.
I installed the mqttjs library according to the instructions on the node website (npm install mqttjs).
In the docs for the mqttjs library they say there is a server example in "examples/broadcast.js". It seems this has been moved to "examples/server/broadcast.js". I'm having some issues running this example though, the server never starts and in the end throws an error. Here is the output from my terminal:
daniel$ pwd
/Users/daniel/test/node_modules/mqttjs/examples/server
daniel$ node broadcast.js
/Users/daniel/test/node_modules/mqttjs/lib/parse.js:113
packet.topic = topic_and_len[0];
^
TypeError: Cannot read property '0' of null

I've tried reading the docs but they do not seem to be updated and I can find no reference on how to run the examples given with the library. If anyone has any experience in this, I'd be very greatful. Thanks.
