Do Angular lifecycle hooks get triggered for each individual component within a nested component hierarchy?

I'm exploring the ins and outs of Angular lifecycle hooks with a conceptual question.

Consider the following nested component structure:

<parent-component>
    <first-child>
        <first-grandchild>
        </first-grandchild>
    </first-child>
    <second-child>
    </second-child>
</parent-component>

If the onChanges lifecycle hook is triggered for one component, will it be triggered for all child and sibling components?

If not, is there a clean way to achieve similar behavior, or is it not possible within Angular's capabilities?

Answer №1

Communication between parent and child components is facilitated through change detection. The ngOnChanges lifecycle method is triggered when a property bound with the @Input() decorator in the parent component changes.
