Services are core classes of any application, and keeping them well organized may be a real challenge. Except if you're working on a small RAD or POC project, your services will quickly grow as messy classes.

This package combines two useful patterns:

- [CQRS](https://martinfowler.com/bliki/CQRS.html) which separates actions (commands) from data retrieval (queries) services.
- [Chain of Responsibility](https://refactoring.guru/design-patterns/chain-of-responsibility) which involves chains of middlewares to handle these commands and queries. Possibilities offered by middleware buses are endless and easily extensible.

It will help you to:

- Decouple *read* and *write* models.
- Wrap every service calls with generic behaviors: *logging, queuing, security, asynchronous handling...*
- Split your services and repositories into multiple classes (enforce *Single Responsibility Principle*).
