Platform packages
This directory contains infrastructure and cross-cutting technical concerns that are independent of Fleet's business domain. These packages provide foundational capabilities used across the codebase.
Platform vs domain
Following separation of concerns, we distinguish:
- Platform (infrastructure): Technical concerns like database connectivity, HTTP utilities, middleware, and transport-level error handling. These packages have no knowledge of Fleet's business domain.
- Domain (business logic): Feature-specific code organized into bounded contexts. Domain packages depend on platform packages, not the reverse.
Guidelines
- Platform packages must not import domain packages
- Platform packages should be general-purpose and reusable
- Architectural boundaries are enforced by
arch_test.go
