YouTube embedded player types for scalajs

Getting Started

The code file is small enought that you should be fine to copy and past the source into your project.

Usage

Note that this file asyncronosly loads the youtube javascript file, so there is no need to include it.

Firt off you will create a target element where the player will get inserted.

<div id="player"></div>

To load the JS file from your Scala project you will have some code like the following:

// 2. This code loads the IFrame Player API code asynchronously.
var tag = org.scalajs.dom.document.createElement("script").asInstanceOf[org.scalajs.dom.html.Script]
tag.src = "https://www.youtube.com/iframe_api"
var firstScriptTag = org.scalajs.dom.document.getElementsByTagName("script").item(0)
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag)

The youtube player will call a window level function named onYouTubeIframeAPIReady when it is done loading and ready to use.

Here is an example of how to handle this call.

// 3. This function creates an <iframe> (and YouTube player) after the API code downloads.
(org.scalajs.dom.window.asInstanceOf[js.Dynamic]).onYouTubeIframeAPIReady = () => {
  val player = new Player("player", PlayerOptions(
    width = "100%",
    height = "100%",
    videoId = "M7lc1UVf-VE",
    events = PlayerEvents(
      onReady = onPlayerReady _,
      onError = onPlayerError _,
      onStateChange = onPlayerStateChange _
    ),
    playerVars = PlayerVars(
      playsinline = 1
    )
  ))
}

That's It !

You know have a typesafe scala friendly youtube player with the full API availavle to you here. https://developers.google.com/youtube/iframe_api_reference
