Having trouble accessing store state in Angular with NGXS

In the parent component, I am dispatching an action and hoping to receive the dispatched array in the child component. To achieve this, I have implemented the following code:

export class ListComponent implements OnInit {
  @Select(ProductState.getProductDetails) listProduct$: Observable<Product>;

   constructor() { 
    //Attempting to access the dispatched array using the following
    const list = this.listProduct$;
    console.log('The array content is ', list);
   }

}

The list$ variable should ideally return an array as I intend to iterate through its elements and perform data filtering.

However, despite my efforts, I have not been able to observe the correct dispatch of data from the parent component in the logs, and consequently, I have been unable to retrieve or modify it in the child component.

Answer №1

When utilizing the selector, it produces an Observable from RxJS. To access the value, ensure to subscribe to it (or opt for the AsynPipe):

this.listItems$.subscribe(items => {
     // Perform actions with items
 });

Remember to unsubscribe to prevent strange/unforeseen errors and memory leaks.
