How do I access the raw (or full) X509 Certificate in a Node.js web app

Given a simple Node.js app:

var https = require('https');
var fs = require('fs');

var options = {
  key: fs.readFileSync('mykey.pem'),
  cert: fs.readFileSync('mycert.pem')
};

https.createServer(options, function (req, res) {
  console.log(req.connection.getPeerCertificate());
  res.writeHead(200);
  res.end("hello world\n");
}).listen(8000);

Results in output to the console with a representation of the certificate, not the original (PEM) format.

Are there other methods available to access the original?
