Commander

Provides a command bus

All you need to do is to create two classes, command and command handler, and pass the command object to the command bus.

How to use the module

1. Create your command handler plugin. That is a class that knows how to execute your command. You can inject any services into your handler class.

<?php
namespace Drupal\my_module\Plugin\CommandHandler;

use Drupal\commander\Contracts\CommandInterface;
use Drupal\commander\Plugin\CommandHandlerBase;

/**
 * @CommandHandler(
 *   id = "register_user_handler",
 *   label = @Translation("Register user handler"),
 * )
 */
class RegisterUserHandler extends CommandHandlerBase {

  public function execute(CommandInterface $command) {
    $data = $command->data;
    
    // Do cool stuff with $data. 

    return TRUE;
  }

}
?>

2. Create your command class and pass any data to it that will be required for executing the command. Make sure to implement the handlerPluginId() method which returns the plugin ID of your command handler.

<?php

namespace Drupal\my_module\Commands;

use Drupal\commander\Contracts\CommandInterface;

class RegisterUser implements CommandInterface {

  public $data;

  public function __construct($data) {
    $this->data = $data;
  }
  
  public function handlerPluginId() {
    return 'register_user_handler';
  }

}
?>

3. Send your command to the command bus for execution.

<?php

$command = new RegisterUser($data);
\Drupal::service('commander.command_bus')->execute($command);
?>
