Readme
Visit
visit
is a PhantomJS-based node module.
It's designed to visits one or multiple urls, runs a CommonJS-aware script in
the context of the page once the page is loaded, grab whatever response it gets
back through the window.callPhantom()
method and parse it as JSON.
visit
's goal is just to be a robust wrapper around PhantomJS, focused on a
single task: get specific data out of a publicly available Web page.
