    });
 });

function readFile(pathToTheFile, cb){
   var fs = require('fs');
   fs.readFile(pathToTheFile, function(err, data){

You can use express.static, set it up early in your app:

app.use('/pdf', express.static(__dirname + '/pathToPDF'));

And it will automatically do the job for you when browser navigates to e.g. '/pdf/fooBar.pdf'.
