I made a website with the Spotify Web API and I want to make an app out of this. My website exists of an html file, Javascript file and lot of plugins. At my website you can log in with Spotify and play tracks. Currently it's running on a local server. localhost:8888

This is the javascript code:

/**

 * This is an example of a basic node.js script that performs

 * the Authorization Code oAuth2 flow to authenticate against

 * the Spotify Accounts.

 *

 * For more information, read

 * https://developer.spotify.com/web-api/authorization- 

 guide/#authorization_code_flow

 */



var express = require('express'); // Express web server framework

var request = require('request'); // "Request" library

var cors = require('cors');

var querystring = require('querystring');

var cookieParser = require('cookie-parser');



var client_id = '********'; // Your client id

var client_secret = '********'; // Your secret

var redirect_uri = 'http://localhost:8888/callback'; // Your redirect uri



/**

* Generates a random string containing numbers and letters

* @param  {number} length The length of the string

* @return {string} The generated string

*/

var generateRandomString = function(length) {

var text = '';

var possible = 

'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';



for (var i = 0; i < length; i++) {

text += possible.charAt(Math.floor(Math.random() * possible.length));

}

return text;

};



var stateKey = 'spotify_auth_state';



var app = express();



app.use(express.static(__dirname + '/public'))

.use(cors())

.use(cookieParser());



app.get('/login', function(req, res) {



var state = generateRandomString(16);

res.cookie(stateKey, state);



// your application requests authorization

var scope = 'user-read-private user-read-email user-read-currently-playing 

user-modify-playback-state';

res.redirect('https://accounts.spotify.com/authorize?' +

querystring.stringify({

  response_type: 'code',

  client_id: client_id,

  scope: scope,

  redirect_uri: redirect_uri,

  state: state

}));

});



app.get('/callback', function(req, res) {



// your application requests refresh and access tokens

// after checking the state parameter



var code = req.query.code || null;

var state = req.query.state || null;

var storedState = req.cookies ? req.cookies[stateKey] : null;



if (state === null || state !== storedState) {

res.redirect('/#' +

  querystring.stringify({

    error: 'state_mismatch'

  }));

} else {

res.clearCookie(stateKey);

var authOptions = {

  url: 'https://accounts.spotify.com/api/token',

  form: {

    code: code,

    redirect_uri: redirect_uri,

    grant_type: 'authorization_code'

  },

  headers: {

    'Authorization': 'Basic ' + (new Buffer(client_id + ':' + 

client_secret).toString('base64'))

  },

  json: true

};



request.post(authOptions, function(error, response, body) {

  if (!error && response.statusCode === 200) {



    var access_token = body.access_token,

        refresh_token = body.refresh_token;



    var options = {

      url: 'https://api.spotify.com/v1/me',

      headers: { 'Authorization': 'Bearer ' + access_token },

      json: true

    };



    // use the access token to access the Spotify Web API

    request.get(options, function(error, response, body) {

      console.log(body);

    });



    // we can also pass the token to the browser to make requests from there

    res.redirect('/#' +

      querystring.stringify({

        access_token: access_token,

        refresh_token: refresh_token

      }));

  } else {

    res.redirect('/#' +

      querystring.stringify({

        error: 'invalid_token'

      }));

  }

});

}

});



app.get('/refresh_token', function(req, res) {



// requesting access token from refresh token

var refresh_token = req.query.refresh_token;

var authOptions = {

url: 'https://accounts.spotify.com/api/token',

headers: { 'Authorization': 'Basic ' + (new Buffer(client_id + ':' + 

client_secret).toString('base64')) },

form: {

  grant_type: 'refresh_token',

  refresh_token: refresh_token

},

json: true

};



request.post(authOptions, function(error, response, body) {

if (!error && response.statusCode === 200) {

  var access_token = body.access_token;

  res.send({

    'access_token': access_token

  });

}

});

});



console.log('Listening on 8888');

app.listen(8888);

How do I need to change it so that it works with Phonegap?
