Fullscreen for PhotoSwipe

This plugin adds a fullscreen display button to the UI to PhotoSwipe 5 by Dmytro Semenov similar to the original fullscreen button in PhotoSwipe 4. In addition to clicking the button you can also press the [F] key to enter fullscreen mode.

The code is inspired by ideas described in dimsemenov/PhotoSwipe#1759.

This plugin is also used in Lightbox with PhotoSwipe, see https://wordpress-demo.arnowelzel.de/lightbox-with-photoswipe-5/ as an example.

Using the plugin

To use the plugin, import the module and create the plugin using the lightbox instance as parameter before you init the lightbox.

<script type="module">
import PhotoSwipeLightbox from 'photoswipe/dist/photoswipe-lightbox.esm.min.js';
import PhotoSwipeFullscreen from 'photoswipe-fullscreen/photoswipe-fullscreen.esm.min.js';

const lightbox = new PhotoSwipeLightbox({
  gallerySelector: '#gallery',
  childSelector: '.pswp-gallery__item',
  pswpModule: () => import('photoswipe/dist/photoswipe.esm.js'),
});

const fullscreenPlugin = new PhotoSwipeFullscreen(lightbox);

// make sure you init photoswipe core after plugins are added
lightbox.init();
</script>

You can also translate the tooltip label of the fullscreen icon:

const fullscreenPlugin = new PhotoSwipeFullscreen(lightbox, {
  fullscreenTitle: 'Toggle fullscreen'
});
