Not able to connect to couchdb with nodejs

i am trying to use cradle to connect couchdb my code is as below:

var cradle = require('cradle');
//grab the packages we need
var c =   new(cradle.Connection)('username:password@127.0.0.1',5984);
var express = require ('express');
var app = express();
var port = process.env.PORT || 6008;

var bodyParser = require('body-parser');

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));

app.post('/cradle/create', function(req, res) {
    var name = req.body.name;
    var db = c.database(name);
  db.create(function(err){
    console.log("ERROR :-(");
    console.log(err);
  });
});
//start the server
app.listen(port);

console.log("server Started on : http://localhost:" + port);

and i am getting this error message displayed in terminal:

{ Error: getaddrinfo ENOTFOUND username:password@127.0.0.1 username:password@127.0.0.1:5984
    at errnoException (dns.js:28:10)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:73:26)
  code: 'ENOTFOUND',
  errno: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'username:password@127.0.0.1',
  host: 'username:password@127.0.0.1 ',
  port: 5984 }
