Command Handling PHP Process

ES with prooph & phunkie

Composition is the key

<?php

namespace Prooph\Micro\Kernel;

use Phunkie\Types\ImmList;
use Phunkie\Types\Kind;
use Phunkie\Validation\Validation;
use Prooph\Common\Messaging\Message;
use Prooph\EventStore\EventStore;
use function Phunkie\Functions\function1\compose;
//...



//Command dispatcher
return compose(
    $handleCommand,
    $enrichEvents, 
    $persistEvents,
    $publishEvents)($command);

f(state, cmd) -> events

ES with prooph & phunkie

Command handling is transactional

//Command dispatcher
return function (Message $command) 
       use ($eventStore, 
            $snapshotStore, 
            $commandMap, 
            $publisher
       ): Validation {
           //...
           $pipe = function () 
                   use ($command, 
                        $handleCommand, 
                        $enrichEvents, 
                        $persistEvents, 
                        $publishEvents
                   ) {
                       return compose(
                           $handleCommand,
                           //...
                       )($command);
                   };

           return Attempt($pipe); // -> Success | Failure
