How can I handle user notifications in Angular when an error occurs?

You can use Angular's built-in services like HttpClient to catch errors and display notifications using a service like Toastr.

Can you show me a code example of that?

Sure! You can create an error handling service that uses Toastr to show notifications. Here's a simple example:

import { Injectable } from '@angular/core';
import { ToastrService } from 'ngx-toastr';

@Injectable({ providedIn: 'root' })
export class NotificationService {
  constructor(private toastr: ToastrService) {}

  showError(message: string) {
    this.toastr.error(message, 'Error');
  }
}

Then, inject this service into your components to display error messages.

What if I want to customize the notifications further?

You can customize Toastr notifications by passing options like position, timeouts, and styles. Check the Toastr documentation for more details.
