For Angular2/4, you can use [hidden] to control the visibility of the spinner. Here is a Plunker.

  
        
     Do something

Where spinning is defined in as:

And your component simply sets the boolean to control the visibility of the spinner. In this example, we simply spin for 10 seconds.

import {Component} from 'angular2/core';
import {Observable} from 'rxjs/Rx';

@Component({
  selector: 'do-something',
  templateUrl: 'src/dosomething.html'
})
export class DoSomething {
   private spin: boolean = false;

   onClickDoSomething() {
     this.spin = true;
     this.sub = Observable.interval(10000).subscribe(x => {
         this.sub.unsubscribe();
         this.spin = false;
     }); 
   }
}
