Installation

npm install @ngu/carousel --save

Include CarouselModule in your app module:

import {
  NguCarousel,
  NguCarouselDefDirective,
  NguCarouselNextDirective,
  NguCarouselPrevDirective,
  NguItemComponent
} from '@ngu/carousel';

@NgModule({
  imports: [
  NguCarousel, 
  NguTileComponent,   
  NguCarousel,
  NguCarouselDefDirective,
  NguCarouselNextDirective,
  NguCarouselPrevDirective,
  NguItemComponent
  ]
})
export class AppModule {}

OR

@Component({
  imports: [
  NguCarousel,
  NguTileComponent,   
  NguCarousel,
  NguCarouselDefDirective,
  NguCarouselNextDirective,
  NguCarouselPrevDirective,
  NguItemComponent
  ],
  standalone: true
})
export class AppComponent {}

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>
      <ul class="myPoint" NguCarouselPoint>
        <li *ngFor="let j of myCarousel.pointNumbers; let j = index" [class.active]="j==myCarousel.activePoint" (click)="myCarousel.moveTo(j)"
          [style.background]="'url(' + carouselTileItems[j] + ')'"></li>
      </ul>
    </ngu-carousel>

  </ngu-tile>
  <button NguCarouselPrev class="leftRs" [style.opacity]="myCarousel.isFirst ? 0.5:1">&lt;</button>

default: {sm: 768, md: 992, lg: 1200, xl: 1200} | | slide | number | optional | It is used to slide the number items on click | | speed | milliseconds | optional | It is used for time taken to slide the number items | | interval | milliseconds | optional | It is used to make the carousel auto slide with given value. interval defines the interval between slides | | load | number | optional | It is used to load the items similar to pagination. The carousel will trigger the carouselLoad function to load another set of items. It will help you to improve the performance of the app.(carouselLoad)="myfunc($event)" | | point.visible | boolean | optional | It is used to indicate no. of slides and also shows the current active slide. | | point.hideOnSingleSlide | boolean | optional | It is used to hide the point indicator when slide is less than one. | | touch | boolean | optional | It is used to active touch support to the carousel. | | easing | string | optional | It is used to define the easing style of the carousel. Only define the ease name without any timing like ease,ease-in | | loop | boolean | optional | It is used to loop the ngu-item | ngu-tile. It must be true for interval | | animation | string | optional | It is used to animate the sliding items. currently it only supports lazy. more coming soon and also with custom CSS animation option | | custom | string | optional | It is you to define the purpose of the carousel. Currently, it only supports banner. | | RTL | boolean | optional | This option enables the rtl direction and acts as rtl. By default it is set to ltr | | vertical.enabled | boolean | optional | This option enables the vertical direction | | vertical.height | number | optional | This option is used to set the height of the carousel |

Custom CSS for Point

<ul class="ngucarouselPoint">
  <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" (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.
