What is AsyncPipe?
Explore how Angular's AsyncPipe simplifies Observable management by handling subscriptions automatically in templates. Understand when to use AsyncPipe versus manual subscription, and how it helps prevent memory leaks by unsubscribing when components are destroyed.
AsyncPipe
One important pipe that we can use in our templates is the AsyncPipe. This works with Observables and helps manage the Subscribing and Unsubscribing from Observables that are used in our components.
The AsyncPipe will return the last value emitted from an Observable and tells the Observable that the value can be checked for the next value in the stream. It will also automatically unsubscribe from the Observable when the component is destroyed or no longer in the UI. This automatic unsubscribing helps reduce the risk of memory leaks in our applications. They can ...
