v1.3.0-beta.2 will be in beta until I update the way ng-packagr works. It is stable enough for production (it's what I am using with Angular Universal and Service Worker).
Also, I am looking for maintainers who also using this package in a production app. I have this requirement because I need maintainers who have a vested interest in the quality of this package. Thanks.
A simple slideshow for Angular 4+.
Click here the check out the demo. Click here the see the slideshow in production on a StoragePug client site, which is what I originally made this slideshow package for.
Features
- NgSimpleSlideshow has no dependencies besides angular. All animations are 100% CSS, so @angular/animations is not needed.
- Compiled and packaged in the Angular Package Format v4.0 with ng-packagr.
- Compiled to es5, so this package is compatible with Angular Universal.
- AOT ready
- Responsive and captures swipes from phones and tablets
- Lazy load option to help with initial pageload speed
Installation
Easy, just npm install:
npm i -S ng-simple-slideshowNext, import the module:
import {SlideshowModule} from 'ng-simple-slideshow';
@NgModule({
imports: [
SlideshowModule,
...
],
declarations: [
...
],
exports: [
...
]
})
...Usage
The simplest use case is the following:
<slideshow [imageUrls]="imageUrlArray"></slideshow>A more complex example of how I use this in one of my own projects (full list of options in next section):
<slideshow [height]="height"
[minHeight]="'525px'"
[autoPlay]="true"
[showArrows]="false"
[imageUrls]="imageSources"
[lazyLoad]="imageSources?.length > 1"
[autoPlayWaitForLazyLoad]="true">
</slideshow>More Info on imageUrls
The imageUrls input can be an array of strings, however in order to enable slides to have links, captions, or custom click functions, you must use an object of type IImage instead of a string. For example usage, see here.

API
Take control of the slideshow if you want! Simply create a reference to your slideshow like so:
<slideshow #slideshow [imageUrls]="imageUrlArray"></slideshow>and in your component.ts reference it as a ViewChild:
@ViewChild('slideshow') slideshow: any;Now you can access the public members such as the goToSlide and onSlide:
this.slideshow.goToSlide(3); // go to slide index 3 (i.e. imageUrls[3])this.slideshow.onSlide(1); // next slidethis.slideshow.onSlide(-1); // previous slide
