Core Classes


All view classes will extend the DOMElement class. Here is an example how you would setup your main applicaiton class.

import FooView from './views/FooView';
import BarView from './views/BarView';
import ExampleView from './views/ExampleView';
class App extends DOMElement {
    _exampleView = null;
    constructor() {
    create() {
        // single instance of a component
        const $exampleView = this.$element.find('#js-ExampleView');
        this._exampleView = new ExampleView($exampleView);
        // multiple instances of a component
            { selector: '.js-FooView', component: FooView },
            { selector: '.js-BarView', component: BarView }
export default App;

To start the application you would use appendTo method on the main application class to attach it to the DOM. Only use appendTo once per application. After that you will use the addChild methed for child views like in the above example. Example of using appendTo:

const app = new App();

DOMElement provides helper methods and adds the following lifecycle to your class, these methods get called in this order:

  • create()
  • enable()
  • layout()
class ExampleView extends DOMElement {
    constructor($element) {
    create() {
        // Create or setup child objects in this parent class.
    enable() {
        if (this.isEnabled === true) { return; }
        // Add any event listeners and/or enable the child objects.
    disable() {
        if (this.isEnabled === false) { return; }
        // Remove any event listeners and/or disable the child objects.
    layout() {
        // Layout or update the objects in this parent class.
    destroy() {
        // Call destroy on any child objects.
        // This super method will also null out your properties for garbage collection.
export default ExampleView;

A base event bus class for managing prioritized queues of event listeners and dispatched events.

// Send data object with the event:
this.dispatchEvent('change', { some: 'data' });
// Example with an event object
// (event type, bubbling set to true, cancelable set to true, and passing data)
let event = new BaseEvent(BaseEvent.CHANGE, true, true, { some: 'data' });
// Dispatching an inline event object
this.dispatchEvent(new BaseEvent(BaseEvent.CHANGE));

A pub/sub static class for dispatching and listening for events.

EventBroker.addEventListener('change', this._handlerMethod, this);
// Using a constant event type
EventBroker.addEventListener(BaseEvent.CHANGE, this._handlerMethod, this);
// Event passed to the method will always be a BaseEvent object.
_handlerMethod(event) {

A static class for managing route patterns for single page applications.

  • {required}
  • :optional:
  • * (all)
// A route listener with an event handler
Router.add('/games/{gameName}/:level:/', this._onRouteHandler, this);
// The above route would match the string below:
// '/games/asteroids/2/'
// The Call back receives a RouterEvent object.
_onRouteHandler(routerEvent) {

Similar to the .on() & .off() jQuery methods, this plugin allows you to bind your function calls and assign them to a property on the class avoiding something like setupHandlers or bindAll methods.

  • eventType
  • delegation (optional)
  • eventHandler
  • scope
enable() {
    if (this.isEnabled === true) { return; }
    this.$element.addEventListener('click', this._onClickHandler, this);
    this.$element.addEventListener('click', 'button', this._onClickHandler, this); // event delegation
disable() {
    if (this.isEnabled === false) { return; }
    this.$element.removeEventListener('click', this._onClickHandler, this);
    this.$element.removeEventListener('click', 'button', this._onClickHandler, this);
_onClickHandler(event) {
    console.log('click', event);
