This is a neat project (with good documentation!). I really like PhantomJS, and it's great for pulling data off of a single page but sometimes it can be a pain to use it to run a series of steps in sequence. I was thinking about trying to hook into the PhantomJS, but this looks like a very clean way to do this. A similar project that is also very useful is pjscrape:
