MeadiatR architecture best practice

[LukasKuchta]

HI, @jbogard, i read your advice why do not send another comman from handler. Better is create notification and consume it.

Is there any hint what system commponent could be command/handler and what service method? Can i use cqrs only for db IO and others requirements make as methods in service? Where are the bounds

1. create customer command
2. publish event
3. send emal - question : should be done by

• a) SendEmailCommand - bad violation your advice
• b) emailService.send()? Based on your advice b) is correct, right?

I would create a notification called UserCreated that is published in the CreateUser handler after the user is Created. Then have a NotificationHandler (called Email, Communication, or something like that) that handles UserCreated and sends an email. If you have other chores that should run after a user is created, just add more handlers.
