Simple implementation of CommandBus and QueryBus that just works.
The CommandBus and QueryBus usage is very similar. The main difference is that the commands don't return a value and the queries return an optional one.
Example
Usage in Symfony:
First you need to add your command handlers and query handlers to a container implementing PSR-11. This container has to be injected into the CommandHandlerLocator and/or the QueryHandlerLocator.
Prepare the query (or the command) and dispatch it through the proper bus.
This is how a query looks, it needs to implement query.
In the handler class is where all the logic to retrieve the value of the query or to execute the command is located:
The optional result is a way to manage a query that can return null or a value. This is not needed for commands because they return void.
