Decorate the method in the controller to run when the page is status unloaded.
Example:
import { Component, OnDestroy, Inject, OnInit } from '@angular/core';
import { OnPageUnloaded } from "angular-page-visibility";
@Component( {
selector : 'app-root',
templateUrl : './app.component.html',
styleUrls : [ './app.component.scss' ]
} )
export class AppComponent implements OnDestroy, OnInit {
...
@OnPageUnloaded()
logWhenPageUnloaded (): void {
console.log( 'OnPageUnloaded => unloaded' );
}
...
}
