htnk128/kotlin-ddd-sample
This system is a Domain-Driven Design reference implementation built with Kotlin and Spring WebFlux, structured around distinct bounded contexts for account and address management. It provides RESTful APIs to create, read, update, and delete accounts and associated addresses, while enforcing domain integrity through value objects, repositories, and domain events. The architecture separates core domain logic from infrastructure concerns, utilizing a modular design with shared abstractions for event publishing and error handling.

How it got here
2018–2019 · DDD domain model implementation
The project was refocused on Domain-Driven Design, evidenced by the renaming to 'kotlin-ddd-sample' and the introduction of core domain models for Account and Address. This period involved establishing the foundational domain logic, including entities, value objects, and domain events, alongside corresponding database migrations and comprehensive unit tests.

2020–2022 · DDD architecture and API implementation
This period focused on establishing a Domain-Driven Design architecture, introducing core domain abstractions, repositories, and domain models for account and address management. The work also involved implementing Spring WebFlux/Boot infrastructure, including REST controllers, error handling, and database utilities to support these domains.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit e8f038c29f — the exact code this score is about.
- Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
