Comparison

Normal `<iframe>` YouTube embed	`lite-youtube`

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:

Include the stylesheet within your application
Include the script as well
Use the lite-youtube tag via HTML or JS.
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 youtube-nocookie.com instead of youtube.com in order to be more privacy friendly for end users.

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.

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('https://i.ytimg.com/vi/ogfYd705cRs/hqdefault.jpg');">
  <button type="button" class="lty-playbtn">
    <span class="lyt-visually-hidden">Play Video: Keynote (Google I/O '18)</span>
  </button>
</lite-youtube>

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('https://i.ytimg.com/vi/ogfYd705cRs/hqdefault.jpg');"></lite-youtube>
