Jobs in Laravel

What are Jobs in Laravel?

Jobs in Laravel are distinct pieces of work that can be run synchronously or queued for asynchronous processing. They are perfect for sending emails, resizing photos, processing file uploads, and communicating with external APIs.


Origin

Jobs are a core part of Laravel's queue system. It was designed to run background jobs and improve app performance by separating heavy tasks from the main app flow.


Why Are Jobs Used?

  1. Handles Long-Running Tasks: Removes time-consuming tasks from the primary request lifecycle to reduce delays.
  2. Boosts User Experience: It runs non-critical tasks in the background. This speeds up response times for users.
  3. Supports Scalability: Distributes job processing across numerous workers or servers, increasing scalability.

Best Practices.

  1. Use Queued Jobs for Heavy Tasks: Always queue resource-intensive jobs to avoid halting the application during execution.
  2. Handle Failures Gracefully: Use retry methods and log unsuccessful jobs for debugging and dependability.
  3. Optimize Worker Configuration: Align worker parameters (e.g., memory limit, process count) with the workload for peak performance.

Example in Action

Create a job:

php artisan make:job SendEmail

In the job class:

namespace App\Jobs;

use Mail;
use App\Models\User;

class SendEmail implements ShouldQueue
{
    public function __construct(public User $user) {}

    public function handle()
    {
        Mail::to($this->user->email)->send(new WelcomeMail());
    }
}

Dispatch the job:

SendEmail::dispatch($user);
