How to convert the request webservice as a function using javascript

Question

I'm having the request script as below and saved as pageRequest.js.

pageRequest.js:

var request = require('request');

var options = {
  method: 'get',
  url: 'http://xx.xx.xx.x/api/....'
};

function callback(error, response, body) {
  var info1 = JSON.parse(body);
  global.info = info1;
}

request(options, callback);

Now I'm executing the above script as part of my protractor onPrepare function. But I need to convert the above pageRequest.js as function and need to call inside my script. can any one help me on this.

By implementing the normal function handler, Can able to convert it as a function.

var request = require('request');

requestHandler: function(){
  var options = {
    method: 'get',
    url: 'http://xx.xx.xx.x/api/....'
  };

  function callback(error, response, body) {
    var info1 = JSON.parse(body);
    global.info = info1;
  }

  request(options, callback);
}
