How can I communicate between Angular directives?

How can I communicate between Angular directives?

You can use a shared service to facilitate communication between directives in Angular. This service can hold the state and allow directives to subscribe to changes.

Can you give me an example of how to set up that service?

Sure! First, create a service using ng generate service shared. Then, define a BehaviorSubject to hold your data. Directives can inject this service and subscribe to the BehaviorSubject.

What if I want to pass data from one directive to another directly?

You can use @Input() and @Output() decorators to pass data directly between parent and child directives. This is effective for one-to-one communication.

Are there any performance considerations I should be aware of?

Yes, excessive use of shared services can lead to performance issues if not managed properly. Always unsubscribe from observables to prevent memory leaks.
