Middleware

Sometimes you need to execute some routines for each incoming messaging object. In order to do this you can exploit the middleware layer. Middleware instances need to implement the Middleware\Layer Class. Middleware can be before the core function:, _(*7)

<?php
namespace MBoretto\MessengerBot\Middleware;
use \Closure;
use \MBoretto\MessengerBot\Objects\Messaging;

class BeforeGetUser extends Layer
{
    public function handle(Messaging $messaging, Closure $next)
    {
        //My routine
        return $next($messaging);
    }
}

or after the core function:, _(*8)

<?php
namespace MBoretto\MessengerBot\Middleware;
use \Closure;
use \MBoretto\MessengerBot\Objects\Messaging;

class BeforeGetUser extends Layer
{
    public function handle(Messaging $messaging, Closure $next)
    {
        $messaging = $next($messaging);
        //My routine
        return $messaging;
    }
}

Then add the middleware in your hook file as explained in the examples.
Middleware is inspired to Lumen/Laravel Pipeline., _(*9)

Commands

Commads needs to be registered in hook.php and must me istance of Commmand.php. - When a Postback update is received, the CommandBus check if payload match the name of a postback command. If this occours the command is executed otherwise the GenericPostbackCommand.php will handle it. - A simple text message is handled by GenericMessageCommand.php - Init commands are executed everytime the webhook is setted, _(*10)
