Modular Monolith With Ddd
This project provides a structured template for building enterprise applications using a modular monolith architecture. It demonstrates how to organize complex business logic into independent, domain-specific modules that remain contained within a single deployment unit.
The architecture enforces strict boundaries between components to minimize coupling and complexity. It utilizes domain-driven design principles to map software components directly to real-world business concepts, ensuring that logic remains independent of infrastructure concerns. Communication between these isolated modules is handled through asynchronous domain events, while a centralized bus pattern decouples request handling from core business logic.
The codebase incorporates practices for maintaining long-term technical strategies, including the use of architectural decision records to document significant design choices. By utilizing persistence-ignorant modeling and internal access modifiers, the framework ensures that domain entities remain testable and protected from cross-module dependency leakage.
