What methods can I employ in Angular 2 to effectively pass ngFor data across various component files?

When working with Angular 2, how can I effectively utilize ngFor to work with data across different component files?

For instance, in my playbar.component.ts file I have the following code snippet:

...
<audio 
 gFor="let audio of sources"                  
 #mediaOne 
 [vgMedia]="mediaOne" 
 id="mediaOne" 
 crossorigin
 [src]="currentItem.src">
...

Meanwhile, in my tunes.component.ts template (with the above file imported), I have the following code:

...
<ul>
  <li *ngFor="let item of sources; let $index = index"
        (click)="onClickPlaylistItem(item, $index)"
        [class.selected]="item === currentItem">
        {{ item.src }}
  </li>
</ul>
...

I'm still learning Angular so please bear with me.

Answer №1

If you need to exchange information between components in Angular, utilizing a Service is the way to go.

For further details on this topic, please refer to this resource

In this scenario, the Service would store the data as observables and both components would then subscribe to these observables.
