Component Templating - html

Question

I'm an angular novice, currently building an angular2 app.
What I want to do is generate a series of DOM components from the following object data:
// Class construct with alphabeticalized properties
export class Screens {
screens: Array<Object>;
}
export var screenData: Screens = {
// Lists all of the audio files in the course
screens: [
{
id: 0,
template: 'templateURL-0.html',
css: 'templateURL-0.css'
},
{
id: 1,
template: 'templateURL-1.html',
css: 'templateURL-1.css'
},
{
id: 2,
template: 'templateURL-0.html',
css: 'templateURL-0.css'
}
]
};
I want the end result to be something similar to the following where template 0 will be displayed twice, and template 1 once; in order:
<app-screen></app-screen> <!-- templateURL-0.html content -->
<app-screen></app-screen> <!-- templateURL-1.html content -->
<app-screen></app-screen> <!-- templateURL-0.html content -->
I read the tutorial on Structural Directives and I think I need to implement something along those lines, however I'm honestly feeling a little lost on the best approach.
Ideally I would like to have something like:
<app-screen *ngFor="let screen of screenData.screens"></app-screen>
Which would then somehow set the template URL depending on what screenData.screens.template is.
Or should I do something like this? (unsure if correct syntax)
<div *ngFor="let screen of screenData.screens" [ngSwitch]="screenData.screens.template">
<app-screen-template1 [ngSwitchCase]="'templateURL-0.html'"></app-screen-template1>
<app-screen-template2 [ngSwitchCase]="'templateURL-1.html'">Ready</app-screen-template2>
</div>
Note: I will never change the templateURL reference.

I found that the best method to achieve this is to implement routing with the built in RouterModule.
So in the end I have the following in my class, where the template property is a url path / url segment.
// Class construct with alphabeticalized properties
export class Screens {
screens: Array<Object>;
}
export var screenData: Screens = {
// Lists all of the audio files in the course
screens: [
{
id: 0,
template: 'template/template-0'
}
]
};
Then when I want to load / instantiate this template, all I have to do is navigate to this url using something like:
<!-- Goes to localhost:4200/template/template-0 -->
<button [routerLink]="[screen.template]"></button>
Where screenis a bound variable in my .ts.
