A DDD shopping cart application focused on separation of concerns and scalability.
Main concepts for this architecture are around codebase scalability. The goal is to provide a clean architecture while flexible for implementing and growing functionalities into the codebase.
Everything is highly testable, given low coupling with clear dependency graphs provided by Inversion of Control.
