It would be nice to have an option to debounce

My use case is a fast scroll from top to bottom.
It would be nice to skip loading all the images in between.

Thanks.

I agree. I will take a look.

This should be possible in the upcoming version 8.0.0-beta.2 (npm install ng-lazyload-image@8.0.0-beta.2). Please try it out and get back to me with what you think.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { debounceTime } from 'rxjs/operators';
import { LazyLoadImageModule, IntersectionObserverHooks, Attributes } from 'ng-lazyload-image';
import { AppComponent } from './app.component';

class LazyLoadImageHooks extends IntersectionObserverHooks {
  getObservable(attributes: Attributes) {
    return super.getObservable(attributes).pipe(debounceTime(1000))
  }
}

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, LazyLoadImageModule.forRoot(LazyLoadImageHooks)],
  bootstrap: [AppComponent],
})
export class MyAppModule {}

Let me know if something is unclear or if it doesn't work for you. The plan is to leave the beta channel in a couple of days.

I have created a sandbox here where you can try it out: https://codesandbox.io/s/lazy-load-image-with-httpclient-to538?file=/src/app/app.module.ts

Scroll down fast and then slowly up

Version 8.0.0 is now out.
Let me know if you have any issues or if it does not solve your issue.
