Deepkit supports various design patterns known from the enterprise environment, such as dependency injection, validation, event system, database abstraction, and many more. These design patterns contribute to the development process by providing reusable and abstracted solutions to common problems. They promote code organization, separation of concerns, and modular architecture, resulting in cleaner and more maintainable code. By leveraging Deepkit's runtime type system, these patterns can be applied in an ergonomic and efficient manner, making development faster and easier.
