Hello i tried rss-watcher but was not able to get any new change. Can anyone just guide me.

Here is my sample code

Is this correct?? [Not able to watch]

feed = 'http://github.com/nikezono.atom'
watcher = new Watcher({feed:feed, interval: 2000 })
watcher.on('new article',function(article){
console.log(article)
})
watcher.run(function(article){
console.log(article)
})
