• Register custom recipient types and channels with callback pattern
• Query registered recipient types and channels

Installation

The package is auto-registered via Laravel's service provider discovery.

Usage

Registering Notification Channels

You can register notification channels in your service provider's boot() method:

use Juzaweb\Modules\Notification\Facades\Notification;
use Juzaweb\Modules\Notification\Channels\EmailChannel;

// Register using a class
Notification::registerChannel('email', fn() => new EmailChannel());

// Or register using anonymous class
Notification::registerChannel('sms', function () {
    return new class implements NotificationChannelInterface {
        public function getLabel(): string {
            return 'SMS';
        }

        public function getDescription(): ?string {
            return 'Send notifications via SMS';
        }

        public function toArray(): array {
            return [
                'label' => $this->getLabel(),
                'description' => $this->getDescription(),
            ];
        }
    };
});

Registering Recipient Types

You can register recipient types in your service provider's boot() method:

use Juzaweb\Modules\Notification\Facades\Notification;

// Register recipient types with callback pattern
Notification::registerRecipientType('all_users', function () {
    return new class implements RecipientTypeInterface {
        public function getLabel(): string {
            return 'All Users';
        }

        public function getDescription(): ?string {
            return 'Send to all registered users';
        }

        public function toArray(): array {
            return [
                'label' => $this->getLabel(),
                'description' => $this->getDescription(),
            ];
        }
    };
});

Notification::registerRecipientType('premium_users', function () {
    return new class implements RecipientTypeInterface {
        public function getLabel(): string {
            return 'Premium Users';
        }

        public function getDescription(): ?string {
            return 'Send to users with premium subscription';
        }

        public function toArray(): array {
            return [
                'label' => $this->getLabel(),
                'description' => $this->getDescription(),
            ];
        }
    };
});

Creating Custom Recipient Types

You can create your own custom recipient type classes by implementing RecipientTypeInterface:

use Juzaweb\Modules\Notification\Contracts\RecipientTypeInterface;

class PremiumUsersRecipientType implements RecipientTypeInterface
{
    public function getLabel(): string
    {
        return __('Premium Users');
    }

    public function getDescription(): ?string
    {
        return __('Send to users with active premium subscription');
    }

    public function toArray(): array
    {
        return [
            'label' => $this->getLabel(),
            'description' => $this->getDescription(),
        ];
    }

    // You can add custom methods
    public function getRecipients(): array
    {
        // Custom logic to get recipients
        return User::where('is_premium', true)->get();
    }
}

// Register the custom type
Notification::registerRecipientType('premium_users', fn() => new PremiumUsersRecipientType());

Creating Custom Notification Channels

Create notification channels by implementing NotificationChannelInterface:

use Juzaweb\Modules\Notification\Contracts\NotificationChannelInterface;

class PushNotificationChannel implements NotificationChannelInterface
{
    public function getLabel(): string
    {
        return __('Push Notification');
    }

    public function getDescription(): ?string
    {
        return __('Send push notifications to mobile devices');
    }

    public function toArray(): array
    {
        return [
            'label' => $this->getLabel(),
            'description' => $this->getDescription(),
        ];
    }
}

// Register the custom channel
Notification::registerChannel('push', fn() => new PushNotificationChannel());

Getting Recipient Types

use Juzaweb\Modules\Notification\Facades\Notification;

// Get all registered recipient types (as objects)
$recipientTypes = Notification::getRecipientTypes();
/*
Returns array of RecipientTypeInterface objects:
[
    'all_users' => RecipientType object,
    'premium_users' => PremiumUsersRecipientType object,
    // ...
]
*/

// Get all registered recipient types as arrays
$recipientTypesArray = Notification::getRecipientTypesArray();
/*
Returns:
[
    'all_users' => [
        'label' => 'All Users',
        'description' => 'Send to all registered users'
    ],
    'premium_users' => [
        'label' => 'Premium Users',
        'description' => 'Send to users with premium subscription'
    ],
    // ...
]
*/

// Get a specific recipient type (as object)
$type = Notification::getRecipientType('all_users');
// Returns RecipientTypeInterface object or null

// Access properties
if ($type) {
    echo $type->getLabel(); // "All Users"
    echo $type->getDescription(); // "Send to all registered users"
}

Getting Notification Channels

use Juzaweb\Modules\Notification\Facades\Notification;

// Get all registered channels (as objects)
$channels = Notification::getChannels();

// Get all registered channels as arrays
$channelsArray = Notification::getChannelsArray();
/*
Returns:
[
    'email' => [
        'label' => 'Email',
        'description' => 'Send notifications via email'
    ],
    'sms' => [
        'label' => 'SMS',
        'description' => 'Send notifications via SMS'
    ],
    // ...
]
*/

// Check if a channel exists
if (Notification::hasChannel('email')) {
    // Channel exists
}

Using in Views

In your controller:

use Juzaweb\Modules\Notification\Facades\Notification;

public function create()
{
    // Get as array for easier use in views
    $recipientTypes = Notification::getRecipientTypesArray();
    $channels = Notification::getChannelsArray();

    return view('notification::create', compact('recipientTypes', 'channels'));
}

In your Blade view:

<select name="recipient_type" class="form-control">
    @foreach($recipientTypes as $key => $type)
        <option value="{{ $key }}">
            {{ $type['label'] }}
            @if(!empty($type['description']))
                - {{ $type['description'] }}
            @endif
        </option>
    @endforeach
</select>

<select name="channels[]" class="form-control" multiple>
    @foreach($channels as $key => $channel)
        <option value="{{ $key }}">
            {{ $channel['label'] }}
            @if(!empty($channel['description']))
                - {{ $channel['description'] }}
            @endif
        </option>
    @endforeach
</select>

Subscriptable Channels

Mark channels as subscriptable to allow users to subscribe/unsubscribe:

use Juzaweb\Modules\Notification\Facades\Notification;

// Mark a channel as subscriptable
Notification::subscriptable('email', [
    'can_unsubscribe' => true,
    'default_enabled' => true,
]);

Notification::subscriptable('sms', [
    'can_unsubscribe' => true,
    'default_enabled' => false,
]);

// Get all subscriptable channels
$subscriptableChannels = Notification::getSubscriptableChannels();
// Returns: ['email', 'sms']

// Get subscriptable data for a specific channel
$emailData = Notification::getSubscriptableData('email');
/*
Returns:
[
    'can_unsubscribe' => true,
    'default_enabled' => true,
]
*/

Sending Bulk Notifications

Use the SendNotificationJob to send notifications to multiple recipients:

use Juzaweb\Modules\Notification\Jobs\SendNotificationJob;
use Juzaweb\Modules\Notification\Models\SentNotification;

// Create a notification
$notification = SentNotification::create([
    'title' => 'System Maintenance',
    'message' => 'The system will be under maintenance tomorrow.',
    'recipient_type' => 'all_users',
    'via' => ['email', 'database'],
]);

// Dispatch job to send notifications
SendNotificationJob::dispatch($notification);

// Or with custom chunk size (default is 100)
SendNotificationJob::dispatch($notification, 50);

The job will:

1. Get recipients from the registered recipient type
2. Process recipients in chunks to avoid memory issues
3. Send notifications via specified channels
4. Update the sent_at timestamp when complete

Bulk Actions in Admin Panel

From the admin panel, you can select multiple notifications and perform bulk actions:

• Delete: Remove selected notifications
• Send: Queue selected notifications for sending

// In your controller
public function bulk(SentNotificationActionsRequest $request)
{
    $action = $request->input('action'); // 'delete' or 'sent'
    $ids = $request->input('ids', []);

    $models = SentNotification::whereIn('id', $ids)->get();

    foreach ($models as $model) {
        if ($action === 'delete') {
            $model->delete();
        }

        if ($action === 'sent') {
            SendNotificationJob::dispatch($model);
        }
    }
}
