Tips for Verifying Browser Closure Status in an Angular 4 Application

In the process of developing my Angular Application, I have successfully implemented Login and Logout functionalities. Upon clicking logout, the user's status in the Database is updated using Laravel API. However, I am facing the challenge of handling the browser close event. In case the user closes the browser, I still need to update their status in the Database. I am unsure how to trigger the Laravel API call on browser close. Any assistance would be highly valued.

Answer №1

Give this solution a shot:

Include the window:beforeunload event listener in your code:

import { Component , HostListener } from '@angular/core';
export class AppComponent {
    @HostListener('window:beforeunload', ['$event'])
    handleBeforeUnload($event) {
        // Add your code here
    }
    constructor() {}
}

Answer №2

Make sure to include the ngOnDestory life cycle hook in your AppComponent (the main component of your application).

export class AppComponent implements OnInit, OnDestory {
...
    ngOnDestory() {
        // Perform necessary clean up tasks here
    }
...
}

As per Angular.io documentation, the ngOnDestory method is a lifecycle hook that gets called when a directive, pipe or service is being destroyed.
