Symfony 4 - CQRS-ES Demonstration

A simple products management application for learning and sharing purpose which's based on Symfony 4 and implemented CQRS-ES within DDD tactical patterns approach:

• Aggregate, Entity, Domain Events, Value Object, Repository
• Layered and Hexagonal (Ports & Adapters) Architecture

Main using components:

• Messenger Component for dispatching command and query.
• JMS Serializer for object (de-)serializing data object

For Event Sourcing (ES), it just implemented a basic concept with a single events stream and synchronous projections. In advanced, it could have multiple streams and asynchronous projections.

Feel free to create your PR if you want to change something to make it better.
