I am creating a simple app. And I pass an array to the child component. When I remove an item from the array, ngOnChanges won't detect the changes unless I refresh the page.
I can log the changes only once at the first page load but not when the array changes.
Thanks in advance for your time.

...ANSWER
Answered 2022-Mar-14 at 11:14I guess the problem is with your change detection. I'm not sure how exactly your service looks like and if it returns observable or array, so the easiest way to check where the problem is:
log
this.shoppingCartin yourdeleteFromCart(). If it logs out the right result ( so the item is removed ) - that means the problem is with change detection. Perhaps you're not assigning the array again, you're just modifying it, so angular doesn't check for the changes. This would mean that you have two options to fix the problem. The better way:

QUESTION
I have a main component that contains two nested components, one of the components contains input fields(2) and a button to add an item, the other sibling component displays the items in a loop.
I have a service that picks the values from the inputting component and updates its array in the service itself.
Whenever I fill the inputs and submit the service adds the new item to the array, but i need to update the sibling component that needs this list to display.
I know I have to obtain the values from the service since it has an updated array.
I dont know which lifecylce hook that I can use in the listing sibling component to fetch the new list since it seems ngOnInit is not called on clicking the Add button.
I dont want to use an event emitter.
Parent Component
...ANSWER
Answered 2020-Jan-09 at 09:08Don't using EventEmitter will be tricky, CPU resources consumming and non-reactive. Let me propose you something :
First create an @Input() ingredients: Ingredient[] to your component ShoppinglistComponent. You already get ingredients in your parent component, so you can pass them to any child component (ShoppinglistComponent in our case)
Then add an @Output() ingredientAdded = new EventEmitter() to your component ShoppinglisteditComponent that you you will fire inside your onAddNewItem method.
In your ShoppinglistComponent listen to the output (ingredientAdded)="insertNewIngredient($event)"
