Introduction

This project is an open source collaborative platform about local commerce.

The purpose of this project is learning the different concepts of DDD and others:

• Value objects
• Entities
• Domain Model
• Aggregate root
• Application layer
• Application services
• Domain layer
• Domain services
• Domain events
• Infrastructure layer
• Presentation layer
• Presenter
• View Model
• Dependency inversion principle
• Factories
• Repositories

For this I used Symfony coupled with Api Platform package, and so I share here my approach on implementing Api platform on a Domain Driven Design project.

Api platform gives you usefull tools to facilitate its use on a Domain Driven Design project application:

• Data Transformers
• Data Providers
• Api resources
• Use of DTO
• etc..

Application structure

My approach

Application
|_  Services
    |_  IdGenerator
    |_  InvoiceService
    |_  OrdersLoader
|_  UseCases
    |_  Consumer
    |_  Deliverer
    |_  Grower
    |_  Invoice
    |_  Order
    Response
    
Domain
|_  Model
|_  Repository
|_  Services
|_  Shared

Infrastucture
|_  Services
|_  Symfony
|_  Templates

Presentation
|_  Api
|_  Web
|_  Command

Shared
|_  Error
|_  Service
|_  SystemClock

Structuring code in modules

A better approach is to separate the application into modules(or Bounded context).

Consumer
|_  Application
|_  Domain
|_  Infrastructure
|_  Presentation
|_  Shared

Deliverer
|_  Application
|_  Domain
|_  Infrastructure
|_  Presentation
|_  Shared

Grower
|_  Application
|_  Domain
|_  Infrastructure
|_  Presentation
|_  Shared

Invoice
|_  Application
|_  Domain
|_  Infrastructure
|_  Presentation
|_  Shared

Order
|_  Application
|_  Domain
|_  Infrastructure
|_  Presentation
|_  Shared
