For implementing Domain-Driven Design (DDD), CQRS, Clean Architecture, and hexagonal architecture within the Kratos framework, it's important to leverage the framework's support for modular design and separation of concerns. Here's a concise guide based on Kratos' capabilities:
- Modular Design: Kratos encourages the development, testing, and maintenance of independent components, aligning with DDD principles.
- Lifecycle Management: Utilize Kratos' lifecycle management for clear separation between initialization, running, and termination phases.
- Service Discovery: Leverage service registration and deregistration for dynamic service discovery, crucial for microservices and DDD architectures.
- Context and Metadata: Use
context.Context
for request-scoped values andAppInfo
for accessing application metadata, supporting clean architecture principles. - Concurrency Management: Employ
errgroup.Group
and synchronization mechanisms for managing parallel operations, facilitating CQRS implementations. - Graceful Shutdown: Handle OS signals for a graceful shutdown, ensuring clean termination and resource cleanup.
- Dependency Injection: Although not explicitly detailed, dependency injection is recommended for managing component dependencies, aligning with clean architecture and hexagonal architecture principles.
For specific implementations of CQRS and how the DDD application layer is represented in Kratos, consider these guidelines as a foundation. Kratos' design supports the separation of concerns, a core aspect of CQRS, by allowing for independent development and management of application components. The application's structure, as seen in the app.go
file, demonstrates Kratos' capabilities in supporting complex architectural patterns.
If you need further details on implementing these architectural patterns specifically with Kratos, including where the separation for CQRS should occur, it might be beneficial to explore more of Kratos' documentation or seek examples within the community. This approach will provide insights into how Kratos can be effectively used to implement DDD, CQRS, Clean Architecture, and hexagonal architecture.

您可以看一下 https://go-kratos.dev/docs/intro/layout 项目结构, 就可以窥探一二; 我自己认为 DDD 没有最佳实战, 结合自己的项目经验和DDD理论, 完全可以找到一种适合自己的DDD最佳实战.

You can take a look at the project structure at https://go-kratos.dev/docs/intro/layout to get a glimpse; I personally think that DDD does not have the best practice. Combining my own project experience and DDD theory, I can definitely find one. The best practice of DDD that suits you.
