import 'hammerjs'; import { enableProdMode } from '@angular/core'; import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';  import { AppModule } from './app/app.module'; import { environment } from './environments/environment';  if (environment.production) {     enableProdMode(); }  document.addEventListener('DOMContentLoaded', () => {     platformBrowserDynamic().bootstrapModule(AppModule)         .catch(err => console.log(err)); });  

Install

npm install --save ngx-image-gallery

Import

import { NgxImageGalleryModule } from 'ngx-image-gallery';  @NgModule({   ...,   imports: [     NgxImageGalleryModule,     ...   ] }) export class AppModule { }

Use

// app.component.html  <ngx-image-gallery  [images]="images"  [conf]="conf" (onOpen)="galleryOpened($event)" (onClose)="galleryClosed()" (onImageClicked)="galleryImageClicked($event)" (onImageChange)="galleryImageChanged($event)" (onDelete)="deleteImage($event)" ></ngx-image-gallery>

Configure

import { Component, OnInit, ViewChild } from '@angular/core'; import { NgxImageGalleryComponent, GALLERY_IMAGE, GALLERY_CONF } from "ngx-image-gallery";  @Component({   selector: 'app-root',   templateUrl: './app.component.html',   styleUrls: ['./app.component.scss'] }) export class AppComponent implements OnInit {   // get reference to gallery component   @ViewChild(NgxImageGalleryComponent) ngxImageGallery: NgxImageGalleryComponent;      // gallery configuration   conf: GALLERY_CONF = {     imageOffset: '0px',     showDeleteControl: false,     showImageTitle: false,   }; 	   // gallery images   images: GALLERY_IMAGE[] = [     {       url: "https://images.pexels.com/photos/669013/pexels-photo-669013.jpeg?w=1260",        altText: 'woman-in-black-blazer-holding-blue-cup',        title: 'woman-in-black-blazer-holding-blue-cup',       thumbnailUrl: "https://images.pexels.com/photos/669013/pexels-photo-669013.jpeg?w=60"     },     {       url: "https://images.pexels.com/photos/669006/pexels-photo-669006.jpeg?w=1260",        altText: 'two-woman-standing-on-the-ground-and-staring-at-the-mountain',        extUrl: 'https://www.pexels.com/photo/two-woman-standing-on-the-ground-and-staring-at-the-mountain-669006/',       thumbnailUrl: "https://images.pexels.com/photos/669006/pexels-photo-669006.jpeg?w=60"     },   ];    constructor(){}    ngOnInit() {} 	   // METHODS   // open gallery   openGallery(index: number = 0) {     this.ngxImageGallery.open(index);   } 	   // close gallery   closeGallery() {     this.ngxImageGallery.close();   } 	   // set new active(visible) image in gallery   newImage(index: number = 0) {     this.ngxImageGallery.setActiveImage(index);   } 	   // next image in gallery   nextImage(index: number = 0) {     this.ngxImageGallery.next();   } 	   // prev image in gallery   prevImage(index: number = 0) {     this.ngxImageGallery.prev();   } 	   /**************************************************/ 	   // EVENTS   // callback on gallery opened   galleryOpened(index) {     console.info('Gallery opened at index ', index);   }    // callback on gallery closed   galleryClosed() {     console.info('Gallery closed.');   }    // callback on gallery image clicked   galleryImageClicked(index) {     console.info('Gallery image clicked with index ', index);   }      // callback on gallery image changed   galleryImageChanged(index) {     console.info('Gallery image changed to index ', index);   }    // callback on user clicked delete button   deleteImage(index) {     console.info('Delete image at index ', index);   } }

Interfaces

// gallery configuration export interface GALLERY_CONF {   imageBorderRadius?: string; // css border radius of image (default 3px)   imageOffset?: string; // add gap between image and it's container (default 20px)   imagePointer? :boolean; // show a pointer on image, should be true when handling onImageClick event (default false)   showDeleteControl?: boolean; // show image delete icon (default false)   showCloseControl?: boolean; // show gallery close icon (default true)   showExtUrlControl?: boolean; // show image external url icon (default true)   showImageTitle?: boolean; // show image title text (default true)   showThumbnails?: boolean; // show thumbnails (default true)   closeOnEsc?: boolean; // close gallery on `Esc` button press (default true)   reactToKeyboard?: boolean; // change image on keyboard arrow press (default true)   reactToMouseWheel?: boolean; // change image on mouse wheel scroll (default true)   reactToRightClick?: boolean; // disable right click on gallery (default false)   thumbnailSize?: number; // thumbnail size (default 30)   backdropColor?: string; // gallery backdrop (background) color (default rgba(13,13,14,0.85))   inline?: boolean; // make gallery inline (default false)   showArrows?: boolean; // show prev / next arrows (default true) }  // gallery image export interface GALLERY_IMAGE {   url: string; // url of the image   thumbnailUrl?: string; // thumbnail url (recommended), if not present, gallery will use `url` property to get thumbnail image.   altText?: string; // alt text for image   title?: string; // title of the image   extUrl?: string; // external url of image   extUrlTarget?: string; // external url target e.g. '_blank', '_self' etc. }

All properties ending with ? are optional.

Make gallery inline

You can make gallery inline like a carousel by setting conf.inline to true but make sure to change conf.backdropColor as well if you need white backdrop color. Also width and height of the gallery can be adjusted by manually applying css styles with !important flag on gallery element.

Dynamic Update

You can update gallery images images and gallery configuration conf anytime you want even when gallery is opened but due to Angular's change detection restrictions you must assign these variable to new value instead of changing internal properties as mentioned below.

// change images this.images = this.images.concat([...]);  // change conf this.conf = {...};
