### Phantomjs function
|
|
|
|
[Phantomjs](http://phantomjs.org) is a headless web-browser used for scraping and automation testing. This function will scrape a web-page with the JavaScript sent in through the function.
|
|
|
|
Once a function has been deployed to FaaS using the UI or one of the other methods you can invoke it with a JavaScript Phantomjs file.

This script visits the front page of CNN and once it is fully loaded - scrapes the title.
|

|
See [cnn.js](https://github.com/alexellis/faas/tree/master/sample-functions/Phantomjs/cnn.js) as an example of a Phantomjs script.

Another example script [feedly_subscribers.js](https://github.com/alexellis/faas/tree/master/sample-functions/Phantomjs/feedly_subscribers.js) gives the count of subscribers for an RSS Feed registered on Feedly.
