In real-world applications, some tasks are time-consuming and should not block HTTP requests:
Sending emails or notifications
Generating reports
Processing images or videos
Importing/exporting data
Laravel queues allow these tasks to run in the background, improving performance and user experience.

Laravel supports multiple queue drivers:
database → store jobs in DB
redis → fast in-memory storage
sqs → AWS SQS cloud queue
Set queue driver in .env:
QUEUE_CONNECTION=databaseRun migration for database queue:
php artisan queue:table
php artisan migrateCreates jobs table to store queued tasks
Generate a job:
php artisan make:job SendEmailJobapp/Jobs/SendEmailJob.php:
<?php
namespace App\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Mail;
class SendEmailJob implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $user;
public function __construct($user)
{
$this->user = $user;
}
public function handle()
{
Mail::raw('Welcome to Laravel Queues!', function ($message) {
$message->to($this->user->email)
->subject('Laravel Queues Example');
});
}
}Implements ShouldQueue → queued job
handle() → task executed in the background
From a controller:
use App\Jobs\SendEmailJob;
public function sendWelcomeEmail($user) {
SendEmailJob::dispatch($user);
return "Email job dispatched!";
}Job is added to queue
Does not block the user request
Run queue worker:
php artisan queue:workContinuously processes jobs in the queue
Stops only on manual termination or system restart
For supervisor in production:
supervisorctl start laravel-workerEnsures queue worker runs continuously even if server restarts
Schedule a job to run later:
SendEmailJob::dispatch($user)->delay(now()->addMinutes(10));Useful for reminders, notifications, or delayed tasks
Configure failed jobs in .env:
QUEUE_FAILED_DRIVER=databaseCreate table:
php artisan queue:failed-table
php artisan migrateCheck failed jobs:
php artisan queue:failedRetry failed jobs:
php artisan queue:retry allLaravel allows batching jobs:
use Illuminate\Bus\Batch;
use Illuminate\Support\Facades\Bus;
$batch = Bus::batch([
new SendEmailJob($user1),
new SendEmailJob($user2)
])->dispatch();Monitor progress and completion status
Useful for bulk tasks like sending newsletter to multiple users
