What methods are available to implement notification sending within Laravel?

Laravel has a built-in Notifications system that allows you to easily send messages through various channels: email, SMS, Slack, databases, and others.

Main implementation methods:

1. Using Notification classes — create a notification class using the command php artisan make:notification, where you define the sending logic for each channel.

2. Sending notifications to users — via the notify() method on the model, for example:

$user->notify(new InvoicePaid($invoice));

3. Sending notifications directly through the Notification facade:

use Illuminate\Support\Facades\Notification;
Notification::send($users, new InvoicePaid($invoice));

4. Using queues — notifications can be sent asynchronously by implementing the ShouldQueue interface in the notification class.

5. Custom channels — you can create your own sending channels if the standard ones are not enough.

Thus, Laravel provides a flexible and extensible way to send notifications through various channels with minimal effort.
