Developing Microservices by using Lumen & RabbitMQ — Part 1

What is RabbitMQ?

RabbitMQ Fundamentals:





Types of exchanges in RabbitMQ:





What we are going to do?

Let’s start!

  • Create a lumen project and name it E-Store.
composer create-project — prefer-dist laravel/lumen estore
  • After installation is completed, in the bootstrap/app.php file uncomment the line
  • Then create two migrations for Order and User Model
  • run the below command:
php artisan make:migration create_users_table
  • Then put the below code in the migration file
  • Run the below command:
php artisan make:migration create_orders_table
  • Then put the below code in the migration file
$table->string('product_name')->default('item 1');
  • The migration for failed jobs also requires so run following command
php artisan queue:failed-table
  • And finally, run:
php artisan migrate
  • populates the tables with some dummy data or you could create a seeder for this task.
  • Add the below code in the $listen array
\App\Events\OrderCreated::class => [
  • Create a class named OrderCreated (extends Event class) in the app/Events folder and put the below code in it
class OrderCreated extends Event
public $order;
public function __construct(Order $order)
$this->order = $order;
  • Then we should create a listener class for our event. In the app/Listeners create one class and name it OrderCreatedListener and put the below code in that class.
namespace App\Listeners;
use Illuminate\Contracts\Queue\ShouldQueue;
use Log;
class OrderCreatedListener implements ShouldQueue

public function __construct()


public function handle($event)
Log::info('Order created on estore:' . json_encode($event));
namespace App\Console\Commands;
use App\Order;
use Illuminate\Console\Command;
class CreateOrder extends Command
protected $signature = 'order:create';

protected $description = 'Create an order';

public function __construct()

public function handle()
$order = Order::with('user')->inRandomOrder()->first();
event(new \App\Events\OrderCreated($order));
return 0;
protected $commands = [
  • Now in the bootstrapp/app.php file, add the below line
php artisan queue:work
  • Then run the below code in another terminal:
php artisan order:create
