Usage
This works across CommonJS/node, AMD and with global variables for the browser.
CommonJS
This is an example of loading either jQuery, Zepto, or Cheerio with a CommonJS module loader, like Node.js.
var $ = requireOne('jquery', 'zepto', 'cheerio'); // => jQuery, Zepto or Cheerio, depending on which one is available.
AMD
This is an example of loading either jQuery, Zepto, or Cheerio with an AMD module loader, like Require.js.
require(['require-one'], function(requireOne) { // Retrieve the first package that is available. var $ = requireOne('jquery', 'zepto', 'cheerio'); // => jQuery, Zepto or Cheerio, depending on which one is available. // ... });
Globals
This is an example of loading either jQuery, Zepto, or Cheerio without a module loader, i.e. with the browser's global variables.
