Installation

Import module:

import { RfxParallaxModule } from 'rfx-parallax';

@NgModule({
  imports: [
    RfxParallaxModule
  ]
})

Initialize parallax

In your app.component.ts initialize parallax listeners inside ngOnInit

import { RfxParallaxService } from 'rfx-parallax';

constructor(private rfxParallaxService: RfxParallaxService) {}

public ngOnInit(): void {
  this.rfxParallaxService.initListeners();
}

and if you have a custom scrollbar component you can pass the nativeElement to the initListeners() function like this:
WARNING: use ngAfterViewInit instead of ngOnInit otherwise your nativeElement may not be defined

<custom-scrollbar #scrollbar>
  <!-- Your page here -->
</custom-scrollbar>

@ViewChild('scrollbar') public scrollbarElement: ElementRef;

public ngAfterViewInit(): void {
  this.rfxParallaxService.initListeners(this.scrollbarElement.nativeElement);
}

<div libRfxParallax imageUrl="<image-path>"></div>
