Youtube Player Aurelia Plugin

Plugin for integrating Youtube iFrame embeds.

The plugin is implemented as aurelia customAttribute.

Basic Usage

Inside <div> container add another div with the customAttribute:

<div class="YourYoutubePlayerContainer">
  <div yt-player="YE7VzlLtp-4"></div>

Note: yt-player value receives the Youtube video ID for the player to play. Make sure to set width and height (can be dynamic) of YourYoutubePlayerContainer. The internal <div yt-player="YE7VzlLtp-4"></div> is replaced by <iframe> which has width and height set to 100%. Changing YourYoutubePlayerContainer size will adjust the video frame size dynamically.

You can dynamically change the Youtube video ID, using something like:
  <div class="YourYoutubePlayerContainer">
    <div yt-player="${videoId}"></div>

Where videoId is property of your custom element.

Note: Youtube requires loading of script. You need to load it manually before the plugin is initialized or read the Initialization Event below.


The plugin makes use of aurelia-event-aggregator to publish different events.

Initialization Event

ytplayer:init:getScript published when the plugin detects is loaded.

Event payload:

  publisher: this,
  data: ''

Your application should load the script when receiving this event. If you use jQuery, you could use something like:

import {inject} from 'aurelia-dependency-injection';
import $ from 'jquery';
import {EventAggregator} from 'aurelia-event-aggregator';

export class App {
  constructor(eventAggregator) {
    this.eventAggregator = eventAggregator;
    this.eventAggregator.subscribe('ytplayer:init:getScript', payload => {
    /* .... */

Note: Youtube requires CORS request so using non csp System.import(...) won't work. That's why to reduce number of dependencies and maximum flexibility the plugin publishes event instead of loading the script.

Load Events

ytplayer:load:player published when plugin loads the Youtube player. ytplayer:load:video published when plugin loads new video.

Events payload is PlayerAPI object.

Player state Events

Delegation of Youtube player onStateChange events

ytplayer:state:cued ytplayer:state:ended ytplayer:state:playing ytplayer:state:paused ytplayer:state:buffering ytplayer:state:unstarted

Events payload is PlayerAPI object.

Player error Events

Delegation of Youtube player onError events

ytplayer:error:invalid-param ytplayer:error:html5 ytplayer:error:not-found ytplayer:error:access-denied ytplayer:error:unknown

Events payload is PlayerAPI object.


Wrapper of Youtube player.

Payload of most of the events and can be used to interact with the player.

interface PlayerAPI {

  play(): void;

  pause(): void;

  getVideoId(): String;

  getDuration(): Number;

  /* DOM element of the embed-code. Especialy usefull if you have number of players */
  getContainer(): Object;


Add configuration options to plugin. Current defaults:

  quality = 'hd720';
  height = '100%';
  width = '100%';
  params = {
    enablejsapi: 1,
    //origin: ''   specify in production
    autoplay: 0,
    showinfo: 0

This skeleton is part of the Aurelia platform. It sets up a standard aurelia plugin using gulp to build your ES6 code with the Babel compiler. Karma/Jasmine testing is also configured.

To keep up to date on Aurelia, please visit and subscribe to the official blog. If you have questions, we invite you to join us on Gitter. If you would like to have deeper insight into our development process, please install the ZenHub Chrome Extension and visit any of our repository's boards. You can get an overview of all Aurelia work by visiting the framework board.

Building The Code

To build the code, follow these steps.

  1. Ensure that NodeJS is installed. This provides the platform on which the build tooling runs.
  2. From the project folder, execute the following command:
npm install
  1. Ensure that Gulp is installed. If you need to install it, use the following command:
npm install -g gulp
  1. To build the code, you can now run:
gulp build
  1. You will find the compiled code in the dist folder, available in three module formats: AMD, CommonJS and ES6.

  2. See gulpfile.js for other tasks related to generating the docs and linting.

Running The Tests

To run the unit tests, first ensure that you have followed the steps above in order to install all dependencies and successfully build the library. Once you have done that, proceed with these additional steps:

  1. Ensure that the Karma CLI is installed. If you need to install it, use the following command:
npm install -g karma-cli
  1. Ensure that jspm is installed. If you need to install it, use the following commnand:
npm install -g jspm
  1. Install the client-side dependencies with jspm:
jspm install
  1. You can now run the tests with this command:
karma start
You can’t perform that action at this time.
