Development

The stylesheet in dist/ is built from src/youtube.scss with Dart Sass — no build pipeline beyond that:

How to use it

Use one of these kirbytags:

Vimeo links that carry a privacy hash for unlisted videos work as well:

Both tags accept class and width.

How the privacy part works

Nothing is loaded from YouTube or Vimeo until the visitor clicks the button:

• The poster image is downloaded once, server side, and stored next to the page, so the preview is served from your own domain.
• The player URL sits in data-src and is only moved to src on click.

For Vimeo the thumbnail is looked up via the public oEmbed endpoint. That lookup only happens when the poster is not on disk yet, so a normal page view never talks to Vimeo.

If the lookup fails — for instance because the video was deleted — the embed still renders, just without a poster and with a 16:9 box. The failure is remembered for a day in the plugin cache, so a dead video does not cost a network timeout on every page view. Clearing the Kirby cache retries earlier.

At most one poster is fetched per request. A page with five new videos would otherwise do ten HTTP requests in a row while the visitor waits; it fills the gap over the next few page views instead.

Reusing the consent notice

video-consent knows nothing about YouTube or Vimeo and can be used for any embed that must not load before consent.

On consent the script hides the poster, reveals .embed-container and moves the iframe URL from data-src to src.

Pass text, button, headline and linkText for anything that is not a video; the defaults talk about videos. buttonClass adds classes to the button so you can reuse your own button style instead of restyling .video-hint-button, and icon shows an image above the headline.

Embeds that are not an iframe — a map that loads a provider script, for instance — need their own click handler. Reuse the notice for the markup and do the loading yourself; the plugin deliberately stays out of that.

Texts

The texts take the provider name as {{ service }}:

Texts without a placeholder pass through unchanged, and the old %s placeholder from 1.x is still filled in — overrides written back then keep working.

Options

Leave cache on — it is what keeps a deleted video from costing a network timeout on every page view.

Upgrading from 1.x

Backwards compatible. The markup now carries both the new generic class names (video-container, video-hint, video-hint-button, …) and the previous youtube-* ones, and stylesheet and script match either. The filenames of the built assets are unchanged.
