DDD Book Shop

Platform: PHP 7.1 Mysql

Framework: Symfony 4

Architecture

Main patterns: DDD, CQRS, Event Sourcing

CQRS command bus was taken from Tactican http://tactician.thephpleague.com

Event Sourcing implementation based on Broadway https://github.com/broadway/broadway

Booth Symfony bundles was spotted from https://github.com/jorge07/symfony-4-es-cqrs-boilerplate one of the best skeleton for DDD which i have ever seen. In real project i will just fork it, but to study i will implement it self.

Domain layer

The domain layer will be divided to next domains:

• User SignUp, SignIn, Unregister, Authorization, Inentification
• Product Keep information of available products and them types(Book is one of the type) on the storage, and reduce/increase that amount
• Order The "heart" of the project, here should initialize main events what should initialize "Purchase" and "Delivery" processes, here it is necessary to implement own Customer entity and OrderItem entity, what should stay even at user or product will be removed.
• Profile Just profile information, update and remove it when user unregister self, or ask it by GDPR reason

Local app setup

1. $ git clone
2. $ composer install
3. Setup DB in the .env file required ENV params:

• DATABASE_HOST=127.0.0.1
• DATABASE_PORT=3306
• DATABASE_NAME=ddd-shop
• DATABASE_USER=root
• DATABASE_PASS=Test1234

4. Create database and tables

   • $ php ./bin/console d:d:c
   • $ php ./bin/console d:s:c
   • $ php ./bin/console d:m:e --up 20180908190647

   NB! Do not use that solution on live servers. Only migrations is available there!

5. Run serve

   • php ./bin/console s:r

   NB! Do not use that solution on live servers. You have to setup normal web server. Ngix or Apache

CLI commands:

Create new user $ php ./bin/console app:create-user email@email.ru password

Create new product $ php ./bin/console app:create-product NAME {product_on_stock} {price}

Endpoints:

Create new user

$ curl -d "email=email@gmail.com&password=password" -X POST http://localhost:8000/api/users

The goal seems unattainable until it is achieved
