Can I use MediatR with this architectural pattern?

Absolutely. The skill includes specific patterns for using MediatR for both in-module CQRS and cross-module integration events to maintain decoupling.

How does this skill handle data isolation?

It provides patterns for creating separate database contexts per module, ensuring each module owns its data and preventing tight coupling through direct database references or foreign keys.

Does this skill support Hexagonal Architecture?

Yes, it includes detailed implementation guides for Ports and Adapters to ensure business logic remains independent of external dependencies like databases or APIs.

What is a modular monolith?

A modular monolith is a software design pattern where the application is built as a single deployable unit but is internally organized into strictly separated modules based on business capabilities.

Is this architecture compatible with microservices?

Yes. The strict boundaries enforced by this modular approach make it significantly easier to extract individual modules into microservices if the need for independent scaling arises.

API Development

Implements structured modular monolith patterns, hexagonal architecture, and isolated data contexts for scalable backend systems.

This skill empowers developers to design and maintain complex software systems by enforcing clear boundaries between business capabilities. It provides standardized patterns for implementing Ports and Adapters (Hexagonal Architecture), configuring inter-module communication via MediatR, and maintaining strict data isolation across bounded contexts. By facilitating the transition from messy monoliths to structured modular architectures, this skill ensures that enterprise applications remain maintainable, testable, and ready for future microservices migration without the overhead of distributed systems.
