ng2-image-gallery v0.3.18

ng2-image-gallery

Basic Angular 2 / 4 image gallery. For compatibility with Angular 5 this issue would have to be resolved: https://github.com/bergben/ng2-image-gallery/issues/9

Demo

A simple demo is available as a plnkr: http://plnkr.co/edit/Qyg5m7XsiKCBpqa6I4ku?p=preview

Install

$ npm install ng2-image-gallery --save

Import the module

// app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { Ng2ImageGalleryModule } from 'ng2-image-gallery'; // <-- import the module
import { MyComponent } from './my.component';

@NgModule({
    imports: [BrowserModule,
              Ng2ImageGalleryModule // <-- include it in your app module
             ],
    declarations: [MyComponent],  
    bootstrap: [MyComponent]
})
export class MyAppModule {}

Import the styles

This library uses Bootstrap 4, so make sure to install that if you want the default styling to apply.

If you use Sass / Scss you can import the styles like so:

@import "{}/node_modules/ng2-image-gallery/ng2-image-gallery.scss";

alternatively just include the css file like this:

<link href="node_modules/ng2-image-gallery/ng2-image-gallery.css" rel="stylesheet" />

Usage

Use it in your template

<ng2-image-gallery [images]="myImages"></ng2-image-gallery> 

whereas "myImages" is an Array of objects that by default would have the following properties:

export interface ImageInterface {
    thumbnail?: any; //image src for the thumbnail
    image?: any; //image src for the image 
    text?: string; //optional text to show for the image
    [propName: string]: any;
}

You can, as it might be more comfortable for you because you have different naming for your properties already, provide different naming for the properties like so:

<ng2-image-gallery [images]="myImages" [asText]="'content'" [asThumbnail]="'mythumb'"></ng2-image-gallery> 

User interaction

You can also add some user interaction to the image by simply providing an actionText.

<ng2-image-gallery [images]="myImages" [actionText]="'do something!'" (onAction)="doSomething($event)"></ng2-image-gallery> 

You can then style the button and listen to the onAction output event.

Draggable / sortable

For administration purposes it might be useful to make the thumbnails draggable so that you can change the order of images in a gallery. Simply set draggable="true" to do so.

<ng2-image-gallery [images]="myImages" [draggable]="true" (onDrop)="onDrop($event)"></ng2-image-gallery> 

You can listen to the onDrop event, which will have a property images which contains the images in the current order.

Contribute

It would be awesome if someone had the time to make some improvements, like:

• animations
• limit to show only 10 thumbnails and then "+x more" etc.
• allow usage of keys

Pull requests are much appreciated!
