Question

I have some node.js code using jsdom and I need jquery.min.js file for backend css selector stuffs. Things ran fine locally but if I deploy using vmc push on api.cloudfoundry.com, it gave me 502 Bad Gateway nginx

I assume I have to declare all dependencies in package.json like here http://blog.nodejitsu.com/package-dependencies-done-right

However, I don’t know how to include jquery.min.js. Right now it is in /lib folder and not /node_modules folder (because it’s not a node module).

Can someone help me on how to include the right dependencies and other extra .js files for Cloud Foundry?

UPDATE 1:

Here is my code after removing bunch of things. If I commenting out the jsdom.env, there is no error.

var port = (process.env.VMC_APP_PORT || 3000);
var host = (process.env.VCAP_APP_HOST || 'localhost');
var http = require('http');

var request = require('request'),
    jsdom = require('jsdom');

http.createServer(function (req, res) {
  request({ uri:'http://www.google.com' }, function (error, response, body) {
    if (error && response.statusCode !== 200) {
      console.log('Error when contacting the url')
    }

    jsdom.env({
      html: body,
      scripts: [
        'lib/jquery.min.js'
      ]
    }, function (err, window) {
    });

    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.write(body);
    res.end('\n');

  });

}).listen(port, host);

Here are what I saw when using vmc logs hp-myapp

Using manifest file manifest.yml

It can’t be contextify because my localhost:3000 ran just fine https://github.com/tmpvar/jsdom/issues/436
