I'm updating an application from Angular 4 to Angular 18 with Django as the backend. When i build the application it gives a infinity loop with the app.component.ts. Added some debuggers and it run the constructor on a loop. But it only happens when i add the . If i add the content of the index without it the loop doesn't happen.
When looping the developers tools is blank and no console show.
Bootstrap error: RangeError: Maximum call stack size exceeded
Exception: error : Maximum call stack size exceeded
RangeError: Maximum call stack size exceeded

Tried removing from app.module.ts the bootstrap AppComponent and loop is gonne, but system don't work.
As the comment says first create a app html file, then reference that instead, the index.html is auto rendered.
@Component({
selector: 'app-root',
templateUrl: 'app.component.html',
providers: [
...
Then make sure you have eouter-outlet set in the app.component.html. This is used to render the routing component.
<nav id="header" class="navbar navbar-expand-md" (click)="toggleMenu($event)">

The index.html should contain only the app-root selector and nothing else.
