Use distribution on your project

The bower install does not include sources and build process. To run the demo, look at the end of this readme.

Install natural-gallery-js :

npm i natural-gallery-js

Include in :

<link rel="stylesheet" href="../dist/themes/natural.css">
<link rel="stylesheet" href="../dist/natural-gallery.full.css">
<script src="../dist/natural-gallery.full.js" defer></script>

If you already have photoswipe loaded on your website, you only need the light version :

<link rel="stylesheet" href="../dist/themes/natural.css">
<link rel="stylesheet" href="../dist/natural-gallery.light.css">
<script src="../dist/natural-gallery.light.js" defer></script>

Recommended Usage (when library is post-loaded)

<div id="gallery"></div>

// Prepare a global array with the list of your galleries
window.naturalGalleries = window.naturalGalleries || [];

// Create your gallery parameters
var gallery = {
    id: 'gallery', // sends id of dom element or
    element: document.getElementById('gallery'), // sends dom element by reference
    options : { // Options

        format: 'natural | square',

        // Max row height. Works for both natural and square format. Prefer this option for a "responsive" approach
        rowHeight: 350,

        // Only for square format. Disables responsive
        imagesPerRow: 4,

        round: 3, // Rounded corner
        margin: 3, // Gap between thumbnails
        limit: 0, // Number of rows, activate pagination (disables infinite scroll)
        minRowsAtStart: 2, // Initial number of rows. If null, gallery tries to define the number of required rows to fill the viewport.

        showLabels: 'hover | always | never', // When to show the labels in thumbnails

        lightbox: true, // Open a lightbox with a bigger image -> activate a zoom effect on hover on thumbnails
        zoomRotation: true,

        // Number of pixels to offset the infinite scroll autoload
        // If negative, next rows will load before the bottom of gallery container is visible
        // If 0 the next rows will load when the bottom of the gallery will be visible
        // If positive, the next rows will load when the bottom of the gallery will be this amount above the end of the viewport.
        // If positive be sure to always have this number of pixels as margin, padding or more content after the gallery.
        infiniteScrollOffset: 0,

        // Header / Search options.
        showCount: false,
        searchFilter: false,
        categoriesFilter: false,
        showNone: false,
        showOthers: false,
        labelCategories: 'Category',
        labelNone: 'None',
        labelOthers: 'Others',
        labelSearch: 'Search',
        labelImages: 'Images',
    },
    images : [
        {
            "thumbnail": "https://images.unsplash.com/photo-1461529959205-ba7d61debd0b?ixlib=rb-0.3.5&q=80&fm=jpg&crop=entropy&w=400&fit=max&s=0653332e9c1498112a303c583c102f6a",

            "title": "Antonio Ron",
            "categories": [
                {

                        "photos": "https://api.unsplash.com/categories/4/photos"
                    }
                }
            ],
            "tWidth": 443.74009508716324,
            "tHeight": 300,
            "eWidth": 2800,
            "eHeight": 1893
        },
        {...}
    ]
};

// Add your gallery to the global array. The NaturalGallery library will start when the script will be loaded.
window.naturalGalleries.push(gallery);

You can then add new pictures when you want :

naturalGalleries[0].appendItems([...]);

Usage when library is pre-loaded

If you load the gallery script in header without defer attribute, you'll need to initiate your galleries manually.

// Init gallery parameters
var gallery = {
    id: 'gallery',
    options : {... },
};

// Call library and add your parameters (re-assign the returned gallery object if you plan to add images later)
gallery = NaturalGallery.add(naturalGallery);

// Init images after load
gallery.images = [...]; // set images as the full collection
gallery.appendItems([...]); // append new images the existing collection

Add to template

Don't forget to add to template the PhotoSwipe layout and icons (if you need header)
