You can get this to work but you'll need another module called jsdom because jQuery needs a DOM window to operate, it's not designed for Node.js. Install it with:

npm install jsdom --save

Please note: I'm using the latest jQuery 2.1.1 and jsdom 1.0.0-pre.6 both installed via npm

And then in your Node.js file e.g. app.js:

var jsdom = require('jsdom'),
    window = jsdom.jsdom().parentWindow,
    $ = require('jquery')(window);

var object = $.extend({},{'foo':'bar'},{'cat':'dog'});
console.log(object);

Then in Node.js you run it:

node app.js

And see the output:

{ foo: 'bar', cat: 'dog' }

Perhaps the better option is to use something like cheerio which is a "fast, flexible, and lean implementation of core jQuery designed specifically for the server". You can install this with npm install cheerio.

jquery is only for client side. For server side (node.js0, it used for unitTest scripting with browserify, ... because node.js has no window, document and DOM layer. I recommand you to use underscore.js : 

npm install underscore

Underscore.js has a extend method works like jquery.extend. : 

var _ = require('underscore');
var obj = _.extend({}, object1, object2);
