Provide simple way to implement Message Bus concept in Symfony.
Thank's @lilobase for you excellent talk at PHP TOUR 2018.
Thank's @matGiWeb for you approach with cqrs-skeleton
CQRS (Command Query Responsibility Segregation) it's an architectural pattern that aims to separate the writing (C 7CE4 ommand) and reading (Query).
symfony powerfull DI with autowire and autoconfigure enable
services:
# default configuration for services in *this* file
_defaults:
autowire: true # Automatically injects dependencies in your services.
autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
public: false
composer require twc/bus-bundle
If you know CQRS pattern, you only have to implement the desired interface
| topic | Interface |
|---|---|
| Command | Twc\BusBundle\Command\Interfaces\Command |
| CommandHandler | Twc\BusBundle\Command\Interfaces\CommandHandler |
| Middleware | Twc\BusBundle\Command\Interfaces\CommandBusMiddleware |
| topic | Interface |
|---|---|
| Event | Twc\BusBundle\Event\Interfaces\Event |
| EventHandler | Twc\BusBundle\Event\Interfaces\EventHandler |
| topic | Interface |
|---|---|
| Query | Twc\BusBundle\Query\Interfaces\Query |
| QueryHandler | Twc\BusBundle\Event\Interfaces\QueryHandler |
| topic | Interface |
|---|---|
| CommandBusDispatcher | Twc\BusBundle\Command\CommandBusDispatcher |
| EventBusDispatcher | Twc\BusBundle\Event\EventBusDispatcher |
| QueryBusDispatcher | Twc\BusBundle\Query\QueryBusDispatcher |
That's all !
CommandBus, EventBus, QueryBus will do the work, thank's Dependencies Injection and autowiring in symfony.
