What are the best practices for using async pipes in Angular?

Using async pipes in Angular helps manage subscriptions automatically. Here are some best practices: 1. Use async pipes in templates to avoid manual subscription management. 2. Prefer using observables over promises for better performance. 3. Keep your observables clean and avoid unnecessary complexity.

Can you explain why using async pipes is better than manual subscriptions?

Async pipes automatically handle subscription and unsubscription, reducing memory leaks and boilerplate code. This makes your code cleaner and more maintainable.

Are there any performance considerations I should be aware of?

Yes, while async pipes are efficient, be cautious with multiple async pipes in a single template, as they can lead to multiple change detections. Optimize your observables to emit only when necessary.

What about error handling with async pipes?

Error handling can be done using the catchError operator in your observable chain. You can also display error messages in the template by checking the observable's state.
