A bunch of tools to implement apps the Flux way

var FluxCapacitor = require('fluxcapacitor');
var TodoActions = require('../actions/TodoActions');
var assign = require('object-assign');

var TodoStore = FluxCapacitor.createStore([TodoActions], {
  events: FluxCapacitor.createEvents(['change']),
  text: '',
  todos: {},
  onCreate: function(action) {
    if (action.text !== '') {
      this.create(action.text);
    }
    this.events.change();
  },
  onToggleCompleteAll: function() {
    if (this.areAllComplete()) {
      this.updateAll({complete: false});
    } else {
      this.updateAll({complete: true});
    }
    this.events.change();
  },
  onDestroyCompleted: function() {

    this.events.change();
  },
  onDestroy: function(action) {
    this.destroy(action.id);
    this.events.change();
  },
  onToggleComplete: function(action) {

    this.events.change();

    }
    this.events.change();
  },
  create: function(text) {
    var id = (+new Date() + Math.floor(Math.random() * 999999)).toString(36);
    this.todos[id] = {
