$welcomeMessage->subject('Welcome '.$newUser>name.'!') Mail::send('emails.welcomeUser',, function ($welcomeMessage) use ($newUser) 'Test User’') Listeners contain the method named handle which contains the instance of the event which in this case is SendEmail instance. So, now comes the listener which will play an important role in this situation. In this code, no information on code that is how to proceed further is given. For example, if the user is registered on the website and we want to send a welcome email to the user – It is created whenever users created their first event and listeners.Īn event holds the data which is going to fire. But if you do not see that directory under the app folder then you have to create that directory first. Where are Events and Listeners stored?īy default, events and listeners are stored in the app directory. Listeners are registered under the events and act accordingly when their events are triggered. They need listeners to perform their actions. For this scenario, Laravel events come into use. So, if any new users are registers, we want to send them the welcome email. So, in Laravel’s case, events are triggered when some condition is met like most websites have authentication systems in which new users are registered. The event basically means the thing that happens or takes place, especially the one that is important. You may add as many events to this array as your application requires.Events are one of the many powerful features of the Laravel. The listen property contains an array of all events (keys) and their listeners (values). The App\Providers\EventServiceProvider included with your Laravel application provides a convenient place to register all of your application's event listeners. Instead of coupling your order processing code to your Slack notification code, you can raise an App\Events\OrderShipped event which a listener can receive and use to dispatch a Slack notification. For example, you may wish to send a Slack notification to your user each time an order has shipped. Don't worry if you don't see these directories in your application as they will be created for you as you generate events and listeners using Artisan console commands.Įvents serve as a great way to decouple various aspects of your application, since a single event can have multiple listeners that do not depend on each other. Event classes are typically stored in the app/Events directory, while their listeners are stored in app/Listeners. Laravel's events provide a simple observer pattern implementation, allowing you to subscribe and listen for various events that occur within your application.
