Responsive Option Example

The responsive option, and value, is quite unique and powerful. You can use it like so:

$(".slider").slick({
  // normal options...
  infinite: false,

  // the magic
  responsive: [
    {
      breakpoint: 1024,
      settings: {
        slidesToShow: 3,
        infinite: true
      }
    },
    {
      breakpoint: 600,
      settings: {
        slidesToShow: 2,
        dots: true
      }
    },
    {
      breakpoint: 300,
      settings: "unslick" // destroys slick
    }
  ]
});

import {LazyLoadService} from 'ngx-slickjs';

constructor(private lazyLoadService: LazyLoadService) {}

  ngAfterViewInit(){
    this.lazyLoadService
      .load(yourScriptUrl, 'script')
      .subscribe(() => {
