Suppose I have a customized component named 'my-component' in Angular.
Is there a method to transform this component into a HTMLElement so it can be passed to a function that requires a HTMLElement as an argument?
I am aware that the HTMLElement is sourced from the following library: lib.dom.d.ts -> located in node_modules -> typescript -> lib -> lib.dom.d.ts -> HTMLElement
Shown below is an image of the element: https://i.sstatic.net/NPlhf.png
The Angular Component class serves as a blueprint rather than a physical element within the DOM. To actually create the element, it must first be included in the Angular Component tree, and then a reference to the element in the DOM can be obtained through the use of ElementRef.
However, this process is only feasible within the Angular Context. If the goal is to utilize an Angular Component outside of Angular, it must be converted into a Custom Element. For a helpful guide on achieving this, check out this tutorial: https://medium.com/@lavanya.kakimallaiah/creating-a-custom-element-in-angular-aa2a794fd041
When you include ElementRef in the constructor, you gain access to elementRef.nativeElement for manipulation.
htmlRef:any
constructor(private elementRef:ElementRef)
{
this.htmlRef=elementRef.nativeElement
}
However, the crucial inquiry remains: Why do we require the htmlRef in Angular?
