Api Cluster Usage in NodeJS

apicluster.js

var http = require('http'),
	ApiCluster = require('apicluster');

ApiCluster
  .defaults({
      name: 'mydefault',
 
      config: {
        'employee': 'emp',
        'details': 'details',
        'timesheet': 'timesheet'
      },
 
      endpoints: {
        "empDetails": "_employee_/_details_/:empId/profile"
      }
  });

//Lets define a port we want to listen to
const PORT = 9000; 

// Function which handles requests and send response
function handleRequest(request, response) {
	var empDetailURL = ApiCluster
                  .get('empDetails')
                  .arg({
                    'empId': 1000 
                  })
                  .query({
                    'confirm': 'yes',
                    'testAccount': 'yes'
                  })
                  .url();
    response.end('<h1>Generated Endpoint URL:<br> '
    	+ empDetailURL + '</h1>');
}

//Create a server
var server = http.createServer(handleRequest);

//Lets start our server
server.listen(PORT, function(){
    // Callback triggered when server is successfully listening. Hurray!
    console.log("Server listening on: http://localhost:%s", PORT);
});
