Usage

  1. Include Carousel needed parts in your module or component (all carousel components and directives are standalone):
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 {}
  1. 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>
  <button NguCarouselNext class="rightRs" [style.opacity]="myCarousel.isLast ? 0.5:1">&gt;</button>
  <ul class="myPoint" NguCarouselPoint>
    <li *ngFor="let i of myCarousel.pointNumbers; let i = index" [class.active]="i==myCarousel.activePoint" (click)="myCarousel.moveTo(i)"
      [style.background]="'url(' + carouselTileItems[i] + ')'"></li>
  </ul>
</ngu-carousel>

  `,
})
export class SampleComponent implements OnInit {
  imgags = [
    'assets/bg.jpg',
    'assets/car.png',
    'assets/canberra.jpg',
    'assets/holi.jpg'
  ];
  public carouselTileItems: Array<any> = [0, 1, 2, 3, 4, 5];

    point: {

    },
    load: 2,
    velocity: 0,
    touch: true,
    easing: 'cubic-bezier(0, 0, 0.2, 1)'
  };
  constructor() {}

  ngOnInit() {
    this.carouselTileItems.forEach(el => {
      this.carouselTileLoad(el);
    });
  }

  public carouselTileLoad(j) {
    // console.log(this.carouselTiles[j]);
    const len = this.carouselTiles[j].length;
    if (len <= 30) {
      for (let i = len; i < len + 15; i++) {
        this.carouselTiles[j].push(
          this.imgags[Math.floor(Math.random() * this.imgags.length)]
        );
      }
    }
  }
}

Command Type Required Description
grid Object Yes xs - mobile, sm - tablet, md - desktop, lg - large desktops, xl - extra large desktops, all - fixed width (When you use all make others 0 and vice versa)
gridBreakpoints Object optional Determines the browser width in pixels that the grid displays the intended number of tiles.

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 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.
