V3 Core Implementation

Structure a TypeScript backend using domain-driven design by isolating business logic into bounded contexts with aggregates, value objects, and repositories. This Skill scaffolds a clean architecture core where domain events drive collaboration and dependency injection wires modular service layers.

A microkernel architecture in TypeScript separates a minimal core from pluggable domain modules. You need bounded contexts when modular services scale, requiring strict domain-driven boundaries to isolate task-management, session-management, and health-monitoring logic.

Set up dependency injection and repository patterns for a DDD TypeScript service by defining repository interfaces in the domain layer and implementing them in external modules. This Skill generates the DI scaffold, wiring repositories and event-driven domain logic into a clean architecture.

Yes, you can use this approach for event-driven microservices. It implements bounded contexts specifically for task-management and session-management, allowing modular TypeScript services to collaborate through domain events while maintaining clean architecture boundaries.

The best way to ensure comprehensive test coverage for domain-driven TypeScript modules is to generate dedicated domain and integration tests alongside the core implementation. This Skill applies test coverage across aggregates, value objects, and event-driven collaboration logic by default.

TypeScript DDD architecture fails to scale without dependency injection because domain modules become tightly coupled to infrastructure. Applying DI with clean architecture boundaries separates repository implementations from domain logic, allowing event-driven bounded contexts to evolve independently.
