Ajax mixin for Flight - https://github.com/twitter/flight

ajax-flight-mixin.js

module.exports = withAjax;

function withAjax() {
  'use strict';

  this.get = function(url, options) {
    this.ajax(url, options, 'get');
  };

  this.post = function(url, options) {
    this.ajax(url, options, 'post');
  };

  this.ajax = function(url, options, type) {
    var xhr = $.extend(options.xhr, {
      context: this,
      type: type,
      dataType: 'json'
    });
    var events = options.events;
    var meta = (typeof options.meta === 'object' ? options.meta : {});

    if (typeof events.before === 'string') {
      this.trigger(events.before);
      delete events.before;
    }

    var req = $.ajax(url, xhr);
    $.each(events, function(key, value) {
      if (typeof value === 'string') {
        req[key](function() {
          // Push meta data in as second member for cleaner
          // callback params
          var args = [].slice.call(arguments, 0);
          args.splice(1, 0, meta);

          this.trigger(value, args);
        });
      }
    });
  }
};

Ah nice, this seems much more succinct. Fixed mine up a little to.

Cheers
