Typescript Ddd Example
This project is a reference implementation for building scalable applications in TypeScript using Domain-Driven Design. It provides a structured codebase template that organizes business logic through tactical design patterns and strategic modeling to ensure the software reflects specific business requirements.
The architecture utilizes a hexagonal pattern to isolate core business logic from external infrastructure concerns such as databases and delivery mechanisms. It implements Command Query Responsibility Segregation to separate data modification operations from information retrieval tasks, and employs a domain event orchestrator to decouple system components.
These patterns facilitate an event-driven approach where asynchronous domain events are broadcast to trigger background workflows. By applying the dependency inversion principle, the implementation ensures that high-level business rules remain independent of low-level technical details.
