Events and listener in laravel

Lets start how to integrated events and listener in laravel in few steps

Step:1 first you need to create a event in laravel

for create an event you need to run a command to you command prompt

php artisan make:event SendMailNotification

this command creates an event inside app/events/SendMailNotification.php

namespace App\Events;use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;class SendMailNotification
use Dispatchable, InteractsWithSockets, SerializesModels;/**
* Create a new event instance.
public $email;
public $message;
public $subject;
public function __construct($email,$message,$subject)
$this->email = $email;
$this->message = $message;
$this->subject = $subject;
* Get the channels the event should broadcast on.
* @return array<int, \Illuminate\Broadcasting\Channel>
public function broadcastOn(): array
return [
new PrivateChannel(‘channel-name’),

in event first you create the variable which you want to pass inside this in above example we define three variable email,subject and message and pass to construct.

Step:2 Create a listener to handle request of event

for create an listener you need to run a command to you command prompt

php artisan make:listener SendMailNotificationFired

this command creates listener at app/listeners/SendMailNotificationFired.php
the code of listener below:-

namespace App\Listeners;use App\Events\SendMailNotification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Mail;
class SendMailNotificationFired
* Create the event listener.
public function __construct()
* Handle the event.
public function handle(SendMailNotification $event): void
//write all login and email here

the function handle pass event and all variable call by event object

Step:3 create a controller to call an event

to create controller run command in command prompt

php artisan make:controller SendEmailNotificationController
the code of controller is below
namespace App\Http\Controllers;
use App\Events\SendMailNotification;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use event;
class SendEmailNotificationController extends Controller
    public function send(){
        $email = ‘’;
        $message = ‘test event fired’;
        $subject = ‘Event-Listener’;
        event(new SendMailNotification($email,$message,$subject));

Step:4 create a route in web.php

use App\Http\Controllers\SendEmailNotificationController;
use Illuminate\Support\Facades\Route;
use Symfony\Component\Mailer\Transport\SendmailTransportFactory;/*
| Web Routes
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider and all of them will
| be assigned to the “web” middleware group. Make something great!
*/Route::get(‘/’, function () {
return view(‘welcome’);
