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:

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

1<!-- Include the CSS & JS.. (This could be direct from the package or bundled) -->
2<link rel="stylesheet" href="node_modules/lite-youtube-embed/src/lite-yt-embed.css" />
3
4<script src="node_modules/lite-youtube-embed/src/lite-yt-embed.js"></script>
5
6<!-- Use the element. You may use it before the lite-yt-embed JS is executed. -->
7<lite-youtube videoid="goiWrNiaT0I" playlabel="Play: Crayon Physics Deluxe - Trailer HD"></lite-youtube>

Privacy note: lite-youtube uses youtube-nocookie.com instead of youtube.com 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.

1<lite-youtube videoid="goiWrNiaT0I" style="background-image: url('https://i.ytimg.com/vi/goiWrNiaT0I/hqdefault.jpg');">
2  <a href="https://youtube.com/watch?v=goiWrNiaT0I" class="lyt-playbtn" title="Play Video">
3    <span class="lyt-visually-hidden">Play Video: Crayon Physics Deluxe - Trailer HD</span>
4  </a>
5</lite-youtube>

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:

1<lite-youtube videoid="goiWrNiaT0I" style="background-image: url('https://i.ytimg.com/vi/goiWrNiaT0I/hqdefault.jpg');"></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="goiWrNiaT0I" js-api>.. Then you can use IFrame Player API:

1const player = await document.querySelector('lite-youtube').getYTPlayer();
2player.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:

1<lite-youtube videoid="goiWrNiaT0I" title="Crayon Physics Deluxe - Trailer HD"></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.

1<!-- Example to show a video player without controls, starting at 10s in, ending at 20s,
2     with modest branding *and* enabling the JS API -->
3<lite-youtube videoid="goiWrNiaT0I" params="controls=0&start=10&end=30&modestbranding=2&rel=0&enablejsapi=1"></lite-youtube>

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