Is it possible in Angular to directly bind the emitted output of a component to a property?

My primary application component communicates with its sub components using @Output decorated properties on the subcomponent. The output properties utilize an EventEmitter<>(). Typically, these properties emit a simple boolean or number. I want to directly bind this output to properties in the main application, but so far my attempts have failed.

Currently, my approach is as follows:

//In my sub-component:
@Output() subProperty = new EventEmitter<boolean>();

//In my main template:
<sub-component (subProperty)="setPropertyValue($event)"></subcomponent>

//In my main component (which I would like to avoid):
setPropertyValue(event) {
    this.mainProperty = event;
}

I hoped to skip the function in my main component and bind directly to my property, but the following code does not work:

//In my sub-component:
@Output() subProperty = new EventEmitter<boolean>();

//In my main template:
<sub-component (subProperty)="mainProperty"></subcomponent>

Is there any way for me to eliminate the extra function in my main component?

Answer №1

In my opinion, the optimal solution is:

(nestedFeature)="primaryFeature = $event"

Answer №2

To utilize the banana/football in the box syntax, simply add the suffix Update to the end of your property. Note that having a corresponding input is not necessary and will be disregarded.

//Within your sub component:
@Output() subPropertyUpdate = new EventEmitter<boolean>();
//Within your main template:
<sub-component [(subProperty)]="mainProperty"></subcomponent>
