Command php artisan make:notification NameOfNotification does not exist in Lumen.

You would have to import that package.

Source: https://stevethomas.com.au/php/using-laravel-notifications-in-lumen.html

The first step is requiring the illuminate/notifications package:

composer require illuminate/notifications

Maybe you will require illuminate/support, i'm not 100% if this is a required dependency for notifications. If you get errors this might be why.

Next, register the service provider in bootstrap/app.php

$app->register(\Illuminate\Notifications\NotificationServiceProvider::class);

// optional: register the Facade
$app->withFacades(true, [
    'Illuminate\Support\Facades\Notification' => 'Notification',
]);

Add the Notifiable trait to whichever models you like, User would be an obvious one:

<?php 

namespace App;

use Illuminate\Notifications\Notifiable;

class User extends Model
{
    use Notifiable;
}

Write notifications the normal way:

<?php

namespace App\Notifications;

use App\Spaceship;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Notifications\Messages\MailMessage;

class SpaceshipHasLaunched extends Notification
{
    use Queueable;

    /** @var Spaceship */
    public $spaceship;

    /**
     * @param Spaceship $spaceship
     */
    public function __construct(Spaceship $spaceship)
    {
        $this->spaceship = $spaceship;
    }

    /**
     * Get the notification's delivery channels.
     *
     * @param mixed $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['mail'];
    }

    /**
     * Get the mail representation of the notification.
     *
     * @param  mixed $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
     */
    public function toMail($notifiable)
    {
        return (new MailMessage)
            ->subject('Spacheship has launched!')
            ->markdown('mail.spaceship', [
                'spaceship' => $this->spaceship
            ]);
    }
}

Send notifications from your app the normal way:

$user->notify(new Notifications\SpaceshipHasLaunched($spaceship));
