A Laravel package that simplifies sending notifications via batch.

Installation

composer require robinthijsen/laravel-notification-batcher

Then run the installation command:

php artisan notification-batcher:install

This will publish the config file and the migration, and ask you if you want to run the migration.

You must also run a queue worker on the batch queue (or the one you defined in the arguments, class property or config file):

php artisan queue:work --queue=batch

How it works

When notifyBatch() is called for the first time for a given notifiable + batch class, the package creates a NotificationBatcher record and dispatches a job with a delay. Any subsequent call within that delay simply increments the count. When the job fires, it calls handle() on your Batch class with the final count.

Usage

1. Add the trait to your notifiable model

use Robinthijsen\NotificationBatcher\Concerns\Batchable;

class User extends Authenticatable
{
    use Batchable;
}

2. Create a Batch class

php artisan make:batch NewMessageBatch

The generated class has a handle() method that receives the notifiable and the NotificationBatcher record. Use $notificationBatcher->count to know how many notifications were batched.

<?php

namespace App\Batches;

use Robinthijsen\NotificationBatcher\Models\NotificationBatcher;

class NewMessageBatch
{
    public function __construct(
        protected $messageId,
    ) {}

    public function handle($notifiable, NotificationBatcher $notificationBatcher)
    {
        $message = Message::findOrFail($this->messageId);
        
        if ($notificationBatcher->count === 1) {
            $notifiable->notifyNow(new NewMessageNotification($this->message));
        } else {
            $notifiable->notifyNow(new NewMessagesNotification($notificationBatcher->count));
        }
    }
}

We recommend passing only IDs as constructor arguments and retrieving models inside handle() method to avoid serialization issues with stale data.

3. Send a batch notification

use Robinthijsen\NotificationBatcher\Facades\Batch;

$user->notifyBatch(new NewMessageBatch());

// or

Batch::to($user)->notifyBatch(new NewMessageBatch());

You can define a custom delay for the batch by passing a CarbonInterval as the second argument:

$user->notifyBatch(new NewMessageBatch(), CarbonInterval::minutes(5));

Or by setting the $delay property on the Batch class:

use Carbon\CarbonInterval;

class NewMessageBatch
{
    public $delay = null;

    public function __construct()
    {
        $this->delay = CarbonInterval::minutes(10);
    }
}

You can also define a custom queue via the third argument:

$user->notifyBatch(new NewMessageBatch(), queue: 'notifications');

Or by setting the $queue property on the Batch class:

class NewMessageBatch
{
    public $queue = 'notifications';
}

If you want to use a queue other than the default one in the package, don't forget to run a worker for that queue.

Configuration

If you installed the package, you should have

php artisan vendor:publish --tag="laravel-notification-batcher-config"

If you installed the package using the command php artisan notification-batcher:install, you should already have the config file published.

return [
    // Directory where Batch classes are generated
    'directory_path' => 'app/Batches',

    // Path to a custom stub (null = use package default)
    'stub_path' => null,

    // Queue name for batch jobs
    'queue' => 'batch',

    // Default delay before the job fires
    'delay' => \Carbon\CarbonInterval::minutes(30),
    
    // Delete the batch record after the job is processed (true = delete, false = keep)
    'delete_after_processed' => true,
];

Priority order for delay: method argument → $batch->delay property → config value.

Priority order for queue: method argument → $batch->queue property → config value.
