Installation

Angular Version	ngu-carousel Version
Angular >= 10	npm i --save @ngu/carousel@latest
Angular = 9	npm i --save @ngu/carousel@2.1.0
Angular < 9	npm i --save @ngu/carousel@1.5.5

Installation

npm install @ngu/carousel --save

Include CarouselModule in your app module:

import { NguCarouselModule } from '@ngu/carousel';
 
@NgModule({
  imports: [NguCarouselModule]
})
export class AppModule {}

Now ngu-carousel supports touch with the help of hammerjs

Import hammerjs in main.ts file

import 'hammerjs';

Then use in your component:

import { Component, OnInit } from '@angular/core';
import { NguCarouselConfig } from '@ngu/carousel';
 
@Component({
  selector: 'sample',
  template: `
    <ngu-carousel #myCarousel [inputs]="carouselTile" [dataSource]="carouselTileItems">
  <ngu-tile *nguCarouselDef="let item; let i = index">
 
    <ngu-carousel #myCarousel [inputs]="carouselTile" (carouselLoad)="carouselTileLoad(i)" [dataSource]="carouselTiles[i]">
      <ngu-tile *nguCarouselDef="let item; let j = index">
        <div class="tile" [style.background]="'url(' + item + ')'" style="min-height: 200px">
          <h1>{{j}}</h1>
        </div>
      </ngu-tile>
      <button NguCarouselPrev class="leftRs" [style.opacity]="myCarousel.isFirst ? 0.5:1">&lt;</button>
      <button NguCarouselNext class="rightRs" [style.opacity]="myCarousel.isLast ? 0.5:1">&gt;</button>

          [style.background]="'url(' + carouselTileItems[j] + ')'"></li>
      </ul>
    </ngu-carousel>

</ul>

This is HTML I'm using in the carousel. Add your own css according to this elements in pointStyles. check below guide for more details.

<ngu-carousel [inputs]="carouselBanner" (onMove)="onmoveFn($event)" (carouselLoad)="loadItemsFn()">
</ngu-carousel>

• inputs is an Input and It accepts NguCarouselConfig.
• onMove is an Output which triggered on every slide before start and it will emit $event as NguCarouselStore object.
• carouselLoad is an Output which triggered when slide reaches the end on items based on inputs load.
