a experimental ktor application using hexagonal architecture
This is a simple user registration application by a kafka command or rest.
The hexagonal architecture was invented by Alistair Cockburn in an attempt to avoid known structural pitfalls in object-oriented software design, such as undesired dependencies between layers and contamination of user interface code with business logic, and published in 2005.
The term "hexagonal" comes from the graphical conventions that shows the application component like a hexagonal cell. The purpose was not to suggest that there would be six borders/ports, but to leave enough space to represent the different interfaces needed between the component and the external world.
you can find a Hexagonal Architecture article here.
All necessary infrastructure is in the docker-compose.yml
$ docker-compose up- ktor to rest layer
- Exposed to database layer
- Koin to dependency injection
- HikariCP to connection pool optimization
- MySql to store data
- JUnit5 as test framework
- Kluent for fluent assertions
- Kotlin as lang
