I am new to Angular2 and was trying to convert owl-carousel in Angularjs to Angular2.

Below is the index.html file for the owl-carousel implementation:

    The above does not work for owl2 because the library expects the class attribute:

    e.g. see this code in owl2:

        if (settings.responsiveClass) {
                this.$element.attr('class',
                    this.$element.attr('class').replace(
         new RegExp('(' +this.options.responsiveClass + '-)\\S+\\s', 'g'), 
          '$1' + match));
    

    make sure to include the class attribute in the element.

    Update

    OwlCarousel2 + Angular2.3.0

    ngOnDestroy() {
      this.$owlElement.owlCarousel('destroy');
      this.$owlElement = null;
    }
    

    Old version

    Below is the app.ts file for the angular2 owl-carousel implementation:

    import {Component} from 'angular2/core';
    import { OwlCarousel } from './owl-carousel.component';
    
    @Component({
      selector: 'app',
      directives: [OwlCarousel],
      template: `
        <h2>Sample 1</h2>
        <owl-carousel [options]="{navigation: true, pagination: false, rewindNav : false}">
           <div *ngFor="#item of items1">
             <p>{{ item }}</p>
           </div>
        </owl-carousel>
        <h2>Sample 2</h2>
        <owl-carousel [options]="{navigation: false, pagination: true, rewindNav : false}">
           <div *ngFor="#item of items2">
             <p>{{ item }}</p>
           </div>
        </owl-carousel>
        <h2>Sample 3</h2>
        <owl-carousel [options]="{navigation: false, pagination: true, rewindNav : false}">
           <div *ngFor="#img of images">
             <img src="http://lorempixel.com/400/200/{{img}}"/>
           </div>
        </owl-carousel>`
    })
    export class App {
      items1: array = [1, 2, 3, 4, 5];
    
      items2: array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
    
      images: array = ['sports', 'abstract', 'people', 'transport', 'city', 'technics', 'nightlife', 'animals'];
    }
    

    owl-carousel.component.ts

    import { Component, Input, ElementRef } from 'angular2/core';
    import $ from 'jquery';
    import 'owl-carousel';
    
    @Component({
      selector: 'owl-carousel',
      template: `<ng-content></ng-content>`
    })
    export class OwlCarousel {
      @Input() options: object;
    
      $owlElement: any;
    
      defaultOptions: object = {};
    
      constructor(private el: ElementRef) {}
    
      ngAfterViewInit() {
        for (var key in this.options) {
          this.defaultOptions[key] = this.options[key];
        }
        this.$owlElement = $(this.el.nativeElement).owlCarousel(this.defaultOptions);
      }
    
      ngOnDestroy() {
        this.$owlElement.data('owlCarousel').destroy();
        this.$owlElement = null;
      }
    }
