// Here, under the hood PhantomJS is opening 
//localhost:3000/uri/goes/here and rendering it to a pdf.
var pdf = new NodePDF('localhost:3000/uri/goes/here', 'filename.pdf', {width:1440, height:900}); //the options might be optional. Play with it a bit.

// This is a callback for what to do on errors
pdf.on('error', function(msg){
    console.log(msg); // you may want to log errors while you're working on it at least.
    // What you might really want to do when done is present an error to the user.
});

// This is a callback for what to do when the pdf finishes rendering. 
//You want to send your response to the client inside the callback so 
//you can ensure the file has been generated before it's requested. 
//Otherwise you might get errors that no file has been found.
pdf.on('done', function(pathToFile){
    //console.log(pathToFile);
    res.render(pathToFile);
