Mastering Background Job Processing in Laravel: A Comprehensive Guide


In modern web applications, tasks that take a significant amount of time to complete should be processed asynchronously in the background. Laravel’s robust queue system allows you to achieve this by dispatching jobs to be processed outside of the main application flow. In this guide, we’ll explore how to set up background job processing in Laravel using queues, covering everything from configuration to execution.

Step 1: Configure Queues

  1. Open the .env file in your Laravel project.
  2. Locate the QUEUE_CONNECTION parameter and set it to database, redis, beanstalkd, or sqs.
  1. Run the following commands to create the required database table for queues
php artisan queue:table
php artisan migrate

Step 2: Create a Job

  1. Generate a job class using the Artisan command
php artisan make:job SendPushNotification
  1. In the app/Jobs/SendPushNotification.php file, implement the ShouldQueue interface and define the handle method. This method will execute the background task.
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;

class SendPushNotification implements ShouldQueue
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $smPayload;

    // Push notification payload as per you need.
    public function __construct(SMPushPayload $smPayload)
        $this->smPayload = $smPayload;

    public function handle()
        $smPush = new SMPush();
        $response = $smPush->send($this->smPayload);

        // Handle the response, log, update database, etc.

Step 3: Dispatch the Job

  1. In your controller or service, create an instance of the payload class.
$smPayload = new SMPushPayload(/* ... */);
  1. Dispatch the job using Laravel’s dispatch method
use App\Jobs\SendPushNotification;

dispatch(new SendPushNotification($smPayload));

Step 4: Run the Queue Worker

  1. Open a new terminal window.
  2. Run the following command to start the queue worker
php artisan queue:work

Step 5: Setting up cronjob

  • Create a Dedicated Queue Worker Script
    • Instead of directly using the php artisan queue:work command, create a dedicated shell script that checks if a queue worker is already running and starts it only if it’s not. Create a new file named and replace /path/to/your/laravel/project with the actual path to your Laravel project's directory.

# Path to Laravel project directory

# Check if queue worker is already running
if ! pgrep -f "artisan queue:work"; then
    cd "$PROJECT_DIR"
    php artisan queue:work --daemon
  • Make the Script Executable:
    • If you are using shared cPanel, you don’t need to worry about this.
chmod +x
  • Set Up a Cron Job:
    • Set up a cron job that runs the script every 10 minute.
    • Replace /path/to/your/laravel/project with the actual path to your Laravel project’s directory.
    • Type crontab -e to add cronjob from terminal and add the script provided bellow crontab -e.
crontab -e
*/10 * * * * /bin/sh /path/to/your/laravel/project/ >> '/dev/null' 2>&1

With this setup, the cron job will execute the script every minute. The script checks if a queue worker process is already running using the pgrep command. If no queue worker process is found, it will start a new one using the php artisan queue:work --daemon command.

  • If you want to terminate the existing queue worker process type following command in your terminal.
pkill -f "artisan queue:work"
  • If you want to see the list of all running processes and then filter that list to only display lines that contain the string use following command.
ps aux | grep "php artisan queue:work"

This approach ensures that only one instance of the queue worker is running at any given time. If a queue worker is already active, the script will skip starting a new one.


By utilizing Laravel’s powerful queue system, you can enhance your application’s performance and responsiveness by processing time-consuming tasks in the background. Background job processing ensures a seamless user experience and improved scalability. With the configuration, job creation, dispatch, and execution covered in this guide, you’re well on your way to mastering background job processing in Laravel.
