@thejlifex/ngx-scroll-spy/lib/spy-target-container.directive.d.ts

An Angular library that can spy the position of elements (inside a scrollable container) and emit the currently active (visible) element in the viewport.

import { OnInit, OnDestroy, ElementRef } from '@angular/core';
import { ScrollSpyService } from './scroll-spy.service';
import * as i0 from "@angular/core";
/**
 * Creates a scroll-spy on this spy targets container (element).
 *
 * Automatically destroys the scroll-spy when the element is destroyed.
 *
 * This is useful:
 *
 * - when you have multiple (independent) scrollable elements on the same page,
 * - or the scrollable element on your page is not the browser default scrollable element, for example `<mat-sidenav-content>` if you are using [Angular Material Sidenav](https://material.angular.io/components/sidenav)
 *
 * where you want to have a scroll-spy.
