My first hook.io microservice

testHook.js

module['exports'] = function echo (hook) {
  // Access Node.js HTTP Request and Response objects
  var req = hook.req,
      res = hook.res;
  // Use NPM Modules
  var faker = require('faker'); 
  res.write('<strong>BYE BILLY</strong> ');
  res.write(req.headers["x-forwarded-for"] + '<br/>');
  res.end(faker.hacker.phrase());
};
