Angular's nativeElement's offsetWidth is 0

I've tried to get offset data of the component in my angular app as below.

this.el.nativeElement.offsetWidth

But it is returning 0 if I don't pass it's css property as below.

this.renderer.setStyle(this.el.nativeElement, 'position', 'fixed');

it is working as I want.returning real value of the native component.But I don't want to change the position property.

Do you suggest me any solution to get current offset data like offsetWidth etc.. you can work on here.

This happens because the component is an inline element by default. You can change its display style attribute to block or inline-block to get the correct size in code:

:host {
  display: block; /* or display: inline-block; */
}

See this stackblitz for a demo.

Some times the element might not have reference to the DOM object. Try doing change detection to refresh the reference. Sorry I am not able to comment.

import ChangeDetectorRef in the constructor

constructor(private changeDetect: ChangeDetectorRef) {}

@ViewChild('splashScreen') el: ElementRef;

getOffSetWidth() {
    // run change detection
    this.changeDetect.detectChanges();
    // And then try getting the offset
    const offsetWidth = this.el.nativeElement.offsetWidth;
    return offsetWidth; 
}
