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,

) {
return compose(
$handleCommand,
//...
)($command);
};
return Attempt($pipe); // -> Success | Failure
