Learn-skills.dev shared-kernel

Shared kernel rules for src/app/shared, defining what can be shared safely (primitives, utilities, UI atoms) and what must not (business logic, cross-context policies); use when adding shared helpers or components.

Shared Kernel

Intent

Provide safe, low-coupling primitives reused across bounded contexts.

Allowed Content

  • Pure utilities (formatting, small helpers) with no side effects.
  • Shared UI atoms/molecules that do not contain business rules.
  • Cross-cutting technical helpers (logging adapters, error wrappers) when they do not introduce new dependencies.

Forbidden Content

  • Business logic, policies, or workflow orchestration.
  • Cross-capability state stores.
  • Domain rules that belong to a specific bounded context.
  • Direct platform SDK usage (Firebase/HTTP) unless the shared item is explicitly an infrastructure primitive and the dependency direction is preserved.

Dependency Discipline

  • Keep dependencies stable and minimal.
  • Avoid importing capability modules into shared.

API Design

  • Prefer small, intention-revealing APIs.
  • Avoid "god" utility modules; create focused files.
