Node.js – can you host a private repository for your organization to use with npm

Update (27-Jun-18): It looks like there was a major update to jsdom that causes the original answer to no longer work. I found this answer that explains how to use jsdom now. I've copied the relevant code below.

var jsdom = require("jsdom");
const { JSDOM } = jsdom;
const { window } = new JSDOM();
const { document } = (new JSDOM('')).window;
global.document = document;

var $ = jQuery = require('jquery')(window);

Note: The original answer fails to mention that it you will need to install jsdom as well using npm install jsdom

Update (late 2013): The official jQuery team finally took over the management of the jquery package on npm:

npm install jquery

Then:

require("jsdom").env("", function (err, window) {
    if (err) {
        console.error(err);
        return;
    }
    var $ = require("jquery")(window);
});

-g is the global install flag, as explained in this answer. It's covered in detail in this node blog post.

The rules of thumb:

• Install globally if the package provides command-line tools
• Install locally if you're using the package as part of your application
• Install globally and locally if both use-cases apply
