Преобразовать статическую библиотеку в общую библиотеку?

Пожалуйста, измените хук OnInit на AfterViewInit.

import { Component, AfterViewInit} from "@angular/core";
declare var jquery:any;
declare var $ :any;
@Component({
  selector: "app-banner",
  templateUrl: './banner.component.html',
  styleUrls: ['./banner.component.css']
})
export class BannerComponent implements AfterViewInit {

  sliders = [
    {"url":"/images/image5.jpg"},
    {"url":"/images/image4.jpg"},
    {"url":"/images/image6.jpg"}
  ];

  constructor() {}

  ngAfterViewInit() {
    $('.slider').bxSlider({
      auto:true
    });

  }


}
