The hexagonal (or "ports and adapters") architecture is a popular software architecture pattern for building Go apps.
The hexagonal architecture divides applications into three main layers: Application layer, Ports and Adapters layer, and Infrastructure layer.
- In Go, the typical hexagonal application uses four main directories: cmd, internal, pkg, and vendor.
- Implementing the hexagonal architecture in Go requires a specific file structure, including directories for adapters, domains, ports, use cases, input/output, and vendor dependencies.
- Advantages of using this architecture include project scalability and maintainability, testability and ease of integration, and flexibility and adaptability to changing requirements.
