Hex

Hex is a sandbox where I try stuff and learn about DDD, Hexagonal Architecture, CQRS and Event Sourcing.

Domain

The problem I'm trying to model in Hex is a meeting room, for which employees can make reservations. The business rules are quite simple:

• A meeting room has a limited capacity
• Meetings cannot take place oustide business hours
• Only one meeting can take place at the same time (no overlap)
• Meeting duration cannot exceed 3h
• Employees can make a reservation up to 7 days in advance
• Employees can consult the meeting room schedule

Documentation

Here are succinct descriptions of concepts related to OOP, DDD, Hexagonal Architecture, CQRS and Event Sourcing. They are described as I understand them, illustrated with code examples.

• Command
• Entity
• Repository
• Specification
• Value Object

Testing

$ ./vendor/bin/phpunit

# You can also give the tests a run for their money
$ ./vendor/bin/humbug

Credits

Hex takes inspiration and borrows a lot of ideas and code from some really awesome PHP projects:

• Broadway by Quandidate Labs
• LiteCQRS for PHP by Benjamin Eberlei
• Predaddy by Janos Szurovecz
• Playground: Event Sourcing by Robin Malfait
