Writing AMD compatible plugins for jQuery

I’ve been tinkering with jQuery a lot these days. My love for the Moo is still strong, but I like switching around from time to time. I also find myself using RequireJS for almost every project big or small and I decided to find a nice way to write jQuery plugins that work with AMD or without.

Straight to the point

The code doesn’t require a massive amount of explanation

// UMD dance - https://github.com/umdjs/umd
!function(root, factory) {
  if (typeof define === 'function' && define.amd) {
    define(['jquery'], factory);
  } else {
}(this, function($) {
  'use strict';

  // Default options
  var defaults = {


  // Constructor, initialise everything you need here
  var Plugin = function(element, options) {
    this.element = element;
    this.options = options;

  // Plugin methods and shared properties
  Plugin.prototype = {
    // Reset constructor - http://goo.gl/EcWdiy
    constructor: Plugin,

    someMethod: function() {


  // Create the jQuery plugin
  $.fn.plugin = function(options) {
    // Do a deep copy of the options - http://goo.gl/gOSSrg
    options = $.extend(true, {}, defaults, options);

    return this.each(function() {
      var $this = $(this);
      // Create a new instance for each element in the matched jQuery set
      // Also save the instance so it can be accessed later to use methods/properties etc
      // e.g.
      //    var instance = $('.element').data('plugin');
      //    instance.someMethod();
      $this.data('plugin', new Plugin($this, options));

  // Expose defaults and Constructor (allowing overriding of prototype methods for example)
  $.fn.plugin.defaults = defaults;
  $.fn.plugin.Plugin = Plugin;

Using the plugin

For non-AMD users they can just use the plugin the same way they always have:

$('.test li').plugin({
  test: 'option1',
  test2: 'option2'

Hot sauce AMD users have a familiar experience but without a need to use shim:

require(['jquery', 'jquery.plugin'], function($) {
  $('.test li').plugin({
    test: 'option1',
    test2: 'option2'

This is just something I came up with whilst fiddling around. Some ideas for improvements are welcomed.
