Laravel Tactician

Laravel Tactician in an implementation of the Command Bus Tactician by Ross Tuck and based on: joselfonseca/laravel-tactician

Installation

Simply do a composer require:

    composer require victormln/laravel-tactician:1.0.*

Or add this line to your composer.json file

    "victormln/laravel-tactician" : "1.0.*"

Other

Once the dependencies have been downloaded, add the service provider to your config/app.php file

    'providers' => [
        ...
        Victormln\LaravelTactician\Providers\LaravelTacticianServiceProvider::class
        ...
    ]

You are done with the installation!

Usage

To use the command bus you can resolve the bus from the laravel container like so

    $bus = app('Victormln\LaravelTactician\CommandBusInterface');

Or you can inject it into a class constructor

    use Victormln\LaravelTactician\CommandBusInterface;

    class MyController extends BaseController
    {

        /** @var CommandBusInterface */
        private $bus;

        public function __construct(CommandBusInterface $bus)
        {
            $this->bus = $bus;
        }

    }

After inject the commandBus, you can dispatch the command as simple as this:

    // First parameter expects the command
    $bus->dispatch(new SimpleCommand());

NOTE: This package is build to automatically grab the CommandHandler from the same path as the Command, so you don't have to do anything to bind the two files. But if you want, you can bind the command handler manually calling the addHandler method

    $bus->addHandler('Path\SimpleCommand', 'Path\SimpleCommandHandler');
    $bus->dispatch(new SimpleCommand());

Example

Check out this example of the package implemented in a simple create order command https://gist.github.com/victormln/f06a86f7204b251d6d6c876d5e516a67

Bindings

You can configure the bindings for the locator, inflector, extractor and default bus publishing the config file like so

    php artisan vendor:publish --provider="Victormln\LaravelTactician\Providers\LaravelTacticianServiceProvider"

Then you can modify each class name and they will be resolved from the laravel container

    return [
        // The locator to bind
        'locator' => 'Victormln\LaravelTactician\Locator\LaravelLocator',
        // The inflector to bind
        'inflector' => 'League\Tactician\Handler\MethodNameInflector\HandleInflector',
        // The extractor to bind
        'extractor' => 'League\Tactician\Handler\CommandNameExtractor\ClassNameExtractor',
        // The bus to bind
        'bus' => 'Victormln\LaravelTactician\Bus'
    ];

Generators

You can generate Commands and Handlers automatically using artisan

artisan make:tactician:command Foo
artisan make:tactician:handler Foo

This will create FooCommand and FooCommandHandler and place them in the app/CommandBus/Commands and app/CommandBus/Handlers respectively

To run both at once

artisan make:tactician Foo

Middleware included

Laravel tactician includes some useful middleware you can use in your commands

• Database Transactions: This Middleware will run the command inside a database transaction, if any exception is thrown the transaction won't be committed and the database will stay intact, you can find this middleware in Victormln\LaravelTactician\Middleware\DatabaseTransactions.
