Although maybe not the most elegant solution, I used the DynamicComponentLoader and ElementRef to dynamically assign template value to a component. In fact, I was looking for a solution where I can add multiple custom components into a placeholder.

I tried service injection in the function as outlined by shmck this doesn't work as the services are not available yet when the template function is called. Indeed, this refers to the Window object.

Reference URLs for the solution I used are to be found on: create dynamic anchorName/Components with ComponentResolver and ngFor in Angular2

I also refer this way to Plnkr1 and Plnkr2.

The site Dartdocs provides nice documentation on Angular 2 DynamicComponentLoader class, also applicable to TypeScript.

In short:

A simple Component as the to be used template

@Component({

  selector: 'dt2-simple-block',

  properties: [idx],

  template: `<h1>Simple block for  {{ idx }} </h1>`,

  directives: []

})

class dt2SimpleBlock {

  constructor() {

  }

}

Constructor of the Component that holds all Components to be added (my app requires multiple childs to be included:

 constructor(loader: DynamicComponentLoader, elementRef: ElementRef) {



  //iterate

  for (var i = 0; i < toSomething; i++) {

      // build the template

      var blockdirective = 'dt2-simple-block'

      var template = '<' + blockdirective + 

                     ' idx=' + this.userBlocks.userHomePanelBlocks[i] +

                     '></' + blockdirective + '>';

      console.log(template);   // debugging purpose

      var directives = [dt2SimpleBlock];

        loader.loadNextToLocation(toComponent(template, directives), elementRef);

    }

And the helper function to be put somewhere as util

function toComponent(template, directives = []) {

  @Component({ selector: 'fake-component' })

  @View({ template, directives })

  class FakeComponent { }



  return FakeComponent;

}
