Скачать или смотреть New in Angular 21: Customize the viewport trigger with options for IntersectionObserver

Angular 21 adds support for passing options to the viewport trigger for IntersectionObserver. This lets you customize settings like rootMargin and use the trigger property to specify which element to watch. All IntersectionObserver options are supported except root, making it easier to control when deferred content loads. The same approach also works for 'prefetch on viewport' and 'hydrate on viewport' triggers.

Thanks to the ‪@Angular‬ Team for the valuable work.
