I'm working with Angular 8 and trying to create a reusable Web Component using the createCustomElement() command in the Angular Elements package "@angular/elements"
So the component itself is very simple. It just contains a some wrapper HTML code and anIMG tag with a src to a logo image. Here is my code.
HTML
<a [routerLink]="homeURL" class="logo-branding no-link flex-grow-2">
<img class="logo align-middle" [src]="headerImgPath">
<span class="branding text-nowrap">{{ this.headerBranding }}</span>
</a>
TS
import { Component, OnInit, Input } from '@angular/core';
@Component({
selector: 'header-logo',
templateUrl: './header-logo.component.html',
styleUrls: ['./header-logo.component.scss'],
})
export class HeaderLogoComponent implements OnInit {
@Input() logo: string;
@Input() branding: string;
@Input() url: string;
public headerImgPath = 'elements-assets/images/my-logo.svg';
public headerBranding = 'Platform Name';
public homeURL: string;
constructor() {}
ngOnInit() {
if (this.branding) {
this.headerBranding = this.branding;
}
if (this.logo) {
this.headerImgPath = this.logo;
}
if (this.url) {
this.homeURL = this.url;
}
}
}
So then I compile the code into a web component inside of the AppModule, like so.
const el = createCustomElement(LogoComponent, { injector: this.injector });
customElements.define('page-logo', el);
And finally pull the exported JS library into a new custom HTML page.
HTML
<div class="container" style="position: relative; height:200px; top: 100px;">
<page-logo></page-logo>
</div>
But what I see is only part of the HTML.
Render in the browser as
<div class="container" style="position: relative; height:200px; top: 100px; >
<my-logo _ngcontent-trw-c0="">
<a class="logo-branding no-link flex-grow-2"></a>
</page-logo>
</div>
The img tag is never rendered at all.
Try this
<a [routerLink]="homeURL" class="logo-branding no-link flex-grow-2">
<img class="logo align-middle" [src]="elements-assets/images/my-logo.svg">
<span class="branding text-nowrap">{{ this.headerBranding }}</span>
</a>
Or this
<a [routerLink]="homeURL" class="logo-branding no-link flex-grow-2">
<img class="logo align-middle" [src]="this.logo">
<span class="branding text-nowrap">{{ this.headerBranding }}</span>
</a>
