Installation

npm install @ngu/carousel --save

Now ngu-carousel supports touch with the help of hammerjs

npm install hammerjs --save

Sample

Include CarouselModule in your app module:

import { NguCarouselModule } from '@ngu/carousel';

@NgModule({
  imports: [
    NguCarouselModule
  ],
})
export class AppModule { }

Import hammerjs in main.ts file

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
import 'hammerjs';

if (environment.production) {
  enableProdMode();
}

document.addEventListener('DOMContentLoaded', () => {
  platformBrowserDynamic().bootstrapModule(AppModule);
});

Then use in your component:

import { Component } from '@angular/core';
import { NguCarousel } from '@ngu/carousel';

@Component({
  selector: 'sample',
  template: `
    <ngu-carousel
        [inputs]="carouselOne"
        (carouselLoad)="myfunc($event)">
          <ngu-item NguCarouselItem>
            ....
          </ngu-item>
          <ngu-item NguCarouselItem>
            ....
          </ngu-item>
          <ngu-item NguCarouselItem>
            ....
          </ngu-item>
          <button NguCarouselPrev class='leftRs'>&lt;</button>
          <button NguCarouselNext class='rightRs'>&gt;</button>
    </ngu-carousel>
  `,
})
export class SampleComponent implements OnInit {

  public carouselOne: NguCarousel;

  ngOnInit() {
    this.carouselOne = {
      grid: {xs: 1, sm: 1, md: 1, lg: 1, all: 0},
      slide: 1,
      speed: 400,
      interval: 4000,
      point: {
        visible: true
      },
      load: 2,
      touch: true,
      loop: true,
      custom: 'banner'
    }
  }

  public myfunc(event: Event) {
     // carouselLoad will trigger this funnction when your load value reaches
     // it is helps to load the data by parts to increase the performance of the app
     // must use feature to all carousel
  }


}

load	number	optional	is used to load the items similar to pagination. the carousel will tigger the carouslLoad function to load another set of items. it will help you to improve the performance of the app.(carouselLoad)="myfunc($event)"

Custom css for Point

<ul class="ngxcarouselPoint">
    <li *ngFor="let i of pointNumbers; let i = index" [class.active]="i==pointers"></li>
</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"
      [moveToSlide]="2"
      (onMove)="onmoveFn($event)"
      (carouselLoad)="loadItemsFn()">
</ngu-carousel>

• inputs is an Input and It accepts NguCarousel.
• moveToSlide is an Input which accepts point numbers. Numbers represents no of slide to be done.
• 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.
