Shop system

Project of the backend of shop

General info

• App is structured using DDD approach, based on the Command Query Responsibility Segregation (CQRS) pattern.
• Several tools are utilized to facilitate the creation of robust code: phpstan (6 level), deptrac, codesniffer.
• The application is well-tested, with tests categorized into Application (E2E), Integration, and Unit tests.
• A caching system based on Redis has been implemented.

Technical solutions

• Directories are organized into /Module, which contains subdirectories for all modules, and /Shared, which includes components shared across all modules. Each module [Order, Product, User] comprises four directories:
  • Application -> houses the implementation of application logic
  • Domain -> contains things related strictly to business information - entities, enums and interfaces of repositories
  • Infrastructure -> includes components related to the technical layer, such as the database and caching system
  • UI -> contains console commands or controllers that serve as the connection between the user and the system
• Actions are classified into commands and queries. I have implemented a custom solution for storing information after the completion of actions. Each command returns a CommandResult, while queries return a QueryResult, which contains information about success, status codes, and retrieved data.
• Authentication is implemented using the JWT approach with the LexikJWTAuthenticationBundle.
• Event sourcing is used to store information about the current status of an order. The latest created order status indicates its current status.
