Ngx Simple Gallery

A simple gallery lib for Angular [20]. It displays all the images as thumbnails and makes it big, when clicked/tapped on it.

• mobile friendly
• lightweight
• use images from any source
• two main forms of use: component selector or directive
• navigate forwards/backwards with keyboard arrows or touch/click on arrows in the showcase dialog
• loading spinner while loading
• smooth animation of the next item
• you can define a thumbnail or leave it empty. It is recommended to provide it though, because of performance reasons.

Installation

npm install --save ngx-simple-gallery @angular/cdk

add the following line to your global styles (by default "styles.(scss|css)") if it is not included yet:

@import '@angular/cdk/overlay-prebuilt.css';

Usage

1. Import the gallery into your component

import { NgxSimpleGalleryComponent } from '@zolcsi/ngx-simple-gallery';

@Component({
  standalone: true,
  imports: [NgxSimpleGalleryComponent],
})
export class AppComponent {}

2. Add the gallery items

import { GalleryItem } from '@zolcsi/ngx-simple-gallery';

@Component({...})
export class AppComponent {
  
  galleryItems: GalleryItem[] = [
    { 
      src: '/img/image1.jpg' 
    }, 
    {
      src: 'https://picsum.photos/id/237/2000/3000',
      thumbnail: 'https://picsum.photos/id/237/160/160',
  }]
}

3. You may configure the gallery with custom settings (optional)

import { GalleryItem } from '@zolcsi/ngx-simple-gallery';

@Component({...})
export class AppComponent {
  
  galleryItems: GalleryItem[] = [...];
  
  galleryConfig: GalleryConfig = {
    emptyMessage: 'No images found in the galleryItems',
    galleryThumbnailSize: 140,
    modalStartIndex: 2,
    showModalThumbnailList: false
  }
}

4. Render the gallery with the items assembled previously (2 ways)

4a. Using the component selector (this renders the images on the page)

<ngx-simple-gallery [galleryItems]="galleryItems" [galleryConfig]="galleryConfig"></ngx-simple-gallery>

or

4b. Using the directive on your own element (this does not render the items on the page, directly opens the modal view)

<p simpleGallery [galleryItems]="galleryItems" [galleryConfig]="galleryConfig">My Gallery</p>
