DDD + CQS + CQRS experiment

Description

We have small application to subscribe users where we'd like to implement Command Query Separation to eventually migrate to the CQRS pattern.

To subscribe a user we call

bin/console user:subscribe [email protected]

We would like you to finish this console action to subscribe a user and print some info about it using CQS best practices. We would also like to record some domain events (well, in this case there's only one possible event) even though there are no listeners at this point. And of course, a little bit of testing (functional, unit) using behat/phpspec or PHPUnit won't hurt either ;)

In the given composer.json you have already included an implementation of the Command Bus pattern using Simple Bus - Message Bus that you may find convenient. Feel free to use any other Command Bus implementation you like.

How to use

Run the development environment:

docker-compose build
docker-compose run --rm --user=$UID:$GID php sh  

Inside the container, you can:

• Install the app

composer install

• Check code style, and execute functional and unit tests

phpcs
behat
phpunit --testdox

Run the console commands:

console user:subscribe <email> #Subscribe a user
console user:subscribed        #Subscription list
