I am trying to find out the logo dimensions, since different clients can upload different logos. The HTML is like this:

<img [src]="layoutResponseModel?.clientLogo" alt="">

How can I get width and height of this image in Angular 5? Found a few JS examples but couldn't make it work

Give your image a template variable a load hook :

<img [src]="layoutResponseModel?.clientLogo" alt="" #logo (load)="onLoad()">

Reference it in your ponent :

@ViewChild('logo') logo: ElementRef;

Write your load hook :

onLoad() {
  console.log((this.logo.nativeElement as HTMLImageElement).width);
}

This will give you the width of the displayed image.
