Job to Command mapper intended to be used with Tactician

Install

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.

composer require wyrihaximus/tactician-job-command-mapper

Set up

When creating a Command add the @Job annotation to map it to one or more jobs.

<?php

namespace Test\App\Commands;

use WyriHaximus\Tactician\JobCommand\Annotations\Job;

/**
 * @Job("awesomesauce")
 * OR
 * @Job({"awesomesauce", "sauceawesome"})
 */
class AwesomesauceCommand
{
}

Mapping

The mapper needs two things, a path where it can find commands. From there it scans all classes it finds for the @Job annotation and stores that map internally

Mapper::map

To add a set of commands simple pass it the path and the mapper will pick up the correct namespaces for you.

use League\Tactician\Setup\QuickStart;

$map = (new Mapper())->map('src' . DS . 'CommandBus');

Mapper::hasCommand

Check if the map has a command for the job we have.

$job = 'awesomesauce';
// True when it has a command or false when it doesn't
$map->hasCommand($job);

Mapper::getCommand

Check if the map has a command for the job we have.

$job = 'awesomesauce';
// Command class when it has a command, or throws an exception when it doesn't
$command = $map->getCommand($job);

// Call the command bus with the command we found to handle the given job
$commandBus->handle(new $command(...$data));

Full class example

final class CommandBusWrapper
{
    /**
      * @var CommandBus
      */
    private $commandBus;
    
    /**
      * @var Mapper
      */
    private $map;
    
    /**
      * @param CommandBus
      */
    public function __construct(CommandBus $commandBus)
    {
        $this->commandBus = $commandBus;
        $this->map = (new Mapper())->map('src' . DS . 'CommandBus', 'App\CommandBus');
    }
    
    /**
      * @param string $job
      * @param array $data
      * @return bool
      */
    function handle(string $job, array $data = []): bool
    {
        if (!$this->map->hasCommand($job)) {
            return false;
        }

        $command = $map->getCommand($job);
        $this->commandBus->handle(new $command(...$data));
        return true;
    }
}
