Is it possible to use different HTML templates for the same TypeScript file, based on an expression in the constructor?
I am looking for something like this:
<div class="container-fluid">
<app-teste1 *ngIf="teste == '1'>
<app-teste2 *ngIf="teste == '2'>
</div>
and in the constructor:
this.teste = 1
So the first component should be rendered (app-teste1).
My component has many properties, is there another way to achieve this without passing various input/output properties?
Currently, in Angular (version 8.0.0-beta.13), the feature you mentioned is not available.
While there are various ways to manipulate and render the DOM tree in Angular, loading a different template file with an extension of .html is not supported at this time.
To create a new component with a different template based on an existing base class, you can simply inherit from the base class and define a new template. Here is an example:
@Component({
selector: 'app-test1',
template: `<div>this is app-test1</div>`
})
export class TestOneComponent {
// ...
}
@Component({
selector: 'app-test2',
template: `<div>this is app-test2</div>`
})
export class TestTwoComponent extends TestOneComponent {
// ...
}
