Description Author

This package can be used for asking confirmation before actions they are executed.

It provides an event handled and dispatcher class that can register event handling callback functions and invokes those functions when the event of that type is emitted.

The package also provides traits uses promises that can be used with classes that can check conditions to confirm that an action can be performed.

Sometimes applications need to perform delicate actions that may not be reversible. In this case it is better that the user is asked to confirm the actions before they are executed to avoid that the user regrets later.

This package can make it easier to implement action confirmation requests right before the requested action is about to happen.

Usage

An event system for simple event-driven programming.

use Preact\Event;

$event = new Event();

$event->on('user.created', function ($user){

});

$user = [
    'id' => 1,
    'name' => 'Admin'
];
$event->emit('user.created', [$user]);

You can use Preact\EventTrait trait directly in your class and have the functionality embedded in your code.

namespace App\User;

use Preact\EventTrait;

class User
{
    use EventTrait;
    
    public function create(array $userInfo)
    {
        //Save in DB
        $this->emit('created', [$userInfo]);
    }
}

$user = new User;

$user->on('created', function ($user){
    echo "User created: {$user['username']}\n";
});

$user->create([
    'username' => 'Admin',
    'email' => 'admin@test.local'
]);

    if($animalInfo['name'] == 'lion'){
        $promisor->resolve(true);
    }else{
        $promisor->reject(false);
    }
});

$animal->preact('can.create', ['lion'])
    ->then(function (){
