Basic usage

Use the lite-youtube-embed npm package or download from this repo and use src/.

To use the custom element you will need to:

  1. Include the stylesheet within your application
  2. Include the script as well
  3. Use the lite-youtube tag via HTML or JS.
  4. Be happy that you're providing a better user experience to your visitors
<!-- Include the CSS & JS.. (This could be direct from the package or bundled) -->
<link rel="stylesheet" href="node_modules/lite-youtube-embed/src/lite-yt-embed.css" />

<script src="node_modules/lite-youtube-embed/src/lite-yt-embed.js"></script>

<!-- Use the element. You may use it before the lite-yt-embed JS is executed. -->
<lite-youtube videoid="ogfYd705cRs" playlabel="Play: Keynote (Google I/O '18)"></lite-youtube>

Privacy note: lite-youtube uses instead of in order to be more privacy friendly for end users.

Pro-usage: load w/ JS deferred (aka progressive enhancement)

Use this as your HTML, load the script asynchronously, and let the JS progressively enhance it.

<lite-youtube videoid="ogfYd705cRs" style="background-image: url('');">
  <a href="" class="lty-playbtn" title="Play Video">
    <span class="lyt-visually-hidden">Play Video: Keynote (Google I/O '18)</span>

Demo: progressive enhancement

Custom poster image

If you want to provide a custom poster image, just set it as the background-image, and lite-yt will not overwrite it:

<lite-youtube videoid="ogfYd705cRs" style="background-image: url('');"></lite-youtube>

Use poster-image-availability.html to determine what poster images are available for you.

Access the YouTube Iframe Player API

Use the js-api param: <lite-youtube videoid="ogfYd705cRs" js-api>.. Then you can use IFrame Player API:

const player = await document.querySelector('lite-youtube').getYTPlayer();
player.seekTo(15); // jump to 15 seconds

Demo: Iframe Player API usage

Add a video title

If you want to display a title prior to loading the full embed, set the title attribute:

<lite-youtube videoid="ogfYd705cRs" title="Keynote (Google I/O '18)"></lite-youtube>

Demo: visible title

Custom Player Parameters

YouTube supports a variety of player parameters to control the iframe's behavior and appearance. These may be applied by using the params attribute.

<!-- Example to show a video player without controls, starting at 10s in, ending at 20s,
     with modest branding *and* enabling the JS API -->
<lite-youtube videoid="ogfYd705cRs" params="controls=0&start=10&end=30&modestbranding=2&rel=0&enablejsapi=1"></lite-youtube>

Note that lite-youtube uses autoplay=1 by default.
