Full screen slides / photo gallery

#1

I need a way to view images in the full screen on devices and be able to swipe between them. Currently I have an ion-slides component that allows swiping through pictures and a PhotoViewer native plugin to allow opening an individual picture in full screen, but I have found no way to swipe between images in the PhotoViewer or view the ion-slides in full screen.

There is an un-maintained plugin that does this but does not work with Ionic 4 (https://www.npmjs.com/package/ionic-gallery-modal).

Is there no simple way to do this? It seems like such a basic use case to me.

For anyone interested, I was able to get my use case working by using the Photoswipe.js library. I’m disappointed that this usecase isn’t supported with ionic plugins.

Full screen image gallery / slider with Photoswipe.js:

npm install --save photoswipe
npm install --save @types/photoswipe

Add to component that you want to use photoswipe on:

import * as Photoswipe from 'photoswipe';
import * as PhotoSwipeUI_Default from "photoswipe/dist/photoswipe-ui-default";

...

var pswpElement = document.querySelectorAll('.pswp')[0];

// build items array
var items = [
    {
        src: 'https://placekitten.com/600/400',
        w: 600,
        h: 400
    },
    {
        src: 'https://placekitten.com/1200/900',
        w: 1200,
        h: 900
    }
];

// define options (if needed)
var options = {
    // optionName: 'option value'
    // for example:
    index: 0 // start at first slide
};

// Initializes and opens PhotoSwipe
var gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items, options);
gallery.init();

Add to index.html before

<!-- Root element of PhotoSwipe. Must have class pswp. -->
<div class="pswp" tabindex="-1" role="dialog" aria-hidden="true">

   <!-- Background of PhotoSwipe.
        It's a separate element as animating opacity is faster than rgba(). -->
   <div class="pswp__bg"></div>

   <!-- Slides wrapper with overflow:hidden. -->
   <div class="pswp__scroll-wrap">

     <!-- Container that holds slides.
         PhotoSwipe keeps only 3 of them in the DOM to save memory.
         Don't modify these 3 pswp__item elements, data is added later on. -->
     <div class="pswp__container">
       <div class="pswp__item"></div>
