Hey thank you so mush for the tuto, I have just 2 small questions

1/In this case wish class represent our Command if we talk CQRS design pattern ? Is it the handler !

2/In wish case we need to create a sender that implement the SenderInterface and a receiver just like it's described under the doc https://symfony.com/doc/cur...
Cheers :)

Hey ahmedbhs

> 1/In this case wish class represent our Command if we talk CQRS design pattern ? Is it the handler !

Yes, a handler can be seen as a command, usually they don't return nothing but it's not forbidden either

> 2/In wish case we need to create a sender that implement the SenderInterface and a receiver just like it's described under the doc

You want to create your own Sender when you need to send a message to a different system. Maybe to another system that you own via its API. And I couldn't think of a better example for a custom Receiver than the one from the docs, sorry!

Cheers!
