V3 Core Implementation

Structure a TypeScript project using domain-driven design by defining bounded contexts, domain entities, aggregates, and repository interfaces. This approach enforces clear dependency boundaries and modular codebases to support scalable, testable application services.

Set up dependency injection by wiring a DI container to resolve repository interfaces and application services. This enables end-to-end workflows where domain events trigger specific actions while maintaining strict testability and decoupled module boundaries.

A shared kernel in clean architecture is a common module containing domain logic shared across bounded contexts. You need it when multiple domains require synchronized behavior or shared value objects, reducing duplication while maintaining strict dependency boundaries.

Yes, this DDD architecture approach works for small TypeScript modules by initializing the core scaffold to begin domain-driven development. It provides a strict TypeScript config and testing scaffold to ensure type-safety and maintainability regardless of project scale.

The best way to test domain entities and aggregates in TypeScript is by using a comprehensive testing scaffold alongside dependency injection. Mocking repository interfaces through the DI container isolates domain logic and verifies domain events without external dependencies.

Domain-driven design requires bounded contexts in TypeScript applications to prevent conceptual overlap and enforce clear dependency boundaries. This modularization stops domain logic from leaking across contexts, ensuring scalable and maintainable application services.
