Backbone.js Sync method for reqwest.js and Ender.js

Backbone.reqwest.js

(function (reqwest, Backbone) {
  var methodMap, getUrl;
  methodMap = {
    'create': 'POST',
    'update': 'PUT',
    'delete': 'DELETE',
    'read'  : 'GET'
  };

  getUrl = function(object) {
    if (!(object && object.url)) return null;
    return _.isFunction(object.url) ? object.url() : object.url;
  };

  // Override `Backbone.sync` to use the lightweight [reqwest](https://github.com/ded/reqwest) ajax library
  // does *not* supports `Backbone.emulateHTTP` and `Backbone.emulateJSON`
  Backbone.sync = function(method, model, options, error) {
    var params;

    params = {
      type: 'json',
      method: methodMap[method],
      headers: { 'Content-Type': 'application/json' },

      success: options.success,
      error: options.error,

      url: options.url? options.url : getUrl(model)
    };

    if (params.method !== 'GET' && params.method !== 'DELETE')
      params.data= JSON.stringify( options.data || model.toJSON());

    console.log(params)
    return reqwest(params);
  };

})( window.reqwest || window.$.ajax,
    window.Backbone || window.$.Backbone); // ender wraps libraries

Like this, took me about 5 minutes to add it in and replace jQuery.
