# Events

Events are an implementation of observer pattern such that whenever an event takes place, then one or more listener(s) associated with that event responds. Imagine something like making an announcement to your application, and then actions being taken due to that announcement. All the event classes in Bagisto are stored in the Providers folder and the listeners are stored in the Listeners folder.

# How to create Event Class?

If you have the Bagisto Package Generator installed, then you can use the following command which will create a new event class in packages/ACME/TestPackage/src/Events directory.

Please follow the following steps to create a new event class in your packages/ACME/TestPackage

  1. We assume that you have created a new TestPackage using Bagisto Package Generator like the below command.

php artisan package:make ACME/TestPackage

  1. Now, you can create a event Events\TestEvent.php class using the below command.

php artisan package:make-event TestEvent ACME/TestPackage

If event class already present then you can use force command for overwriting by passing --force option.

php artisan package:make-event TestEvent ACME/TestPackage --force

Or if you don't have package generator then, you can create file manually also.

# How to create Listener Class?

If you have the Bagisto Package Generator installed, then you can use the following command which will create a new listener class in packages/ACME/TestPackage/src/Listeners directory.

php artisan package:make-listener TestListener ACME/TestPackage

If listener class already present then you can use force command for overwriting.

php artisan package:make-listener TestListener ACME/TestPackage --force

Or if you don't have package generator then, you can create file manually also.

# Manually Registering Events

For the sake of simplicity, in bagisto, we register events manually in the boot method of your EventServiceProvider.php as below:

/**
* Register any other events for your application.
*
* @return void
*/

public function boot()
{
    parent::boot();

    Event::listen('event.name', 'path-upto-listener@function');
}

# Manually Registering Listeners

In registering events, we specify listener function to be executed when an event is called so on every event a listener function is to be executed

class EventServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap services.
    *
    * @return void
    */
    public function boot()
    {
        Event::listen('checkout.order.save.after', 'Webkul\Admin\Listeners\Order@sendNewOrderMail');
    }
}

# How we specify events?

In most of CRUD operation, we had fired an event before and after the execution of function. So, that if some one want to perform any operation after or before product create/update/delete can perform by simply calling a listener function in event registration

# Events Fired in Bagisto

Events fired in bagisto but not listened such that if any user wants to perform any action on event fire, then they may create listener file and perform the respective operation.
