Organize your Angular folder structure by classifying code into core, layout, ui, feature, or pattern areas based on responsibility. Place artifacts in the narrowest valid folder instead of a generic shared directory to keep architecture clean and import-safe.

Enforce import boundaries by ensuring layout areas remain independent from feature implementation. Promote reuse through pattern, ui, or core areas instead of cross-feature implementation imports to maintain a strict one-way dependency direction.

Configure lazy routing by placing feature route configurations in the owning feature folder as *.routes.ts files. This encourages lazy loading patterns and keeps route ownership clearly tied to its specific feature area.

When refactoring Angular apps, classify services by responsibility and place them in the narrowest valid folder. Use core for app-wide singletons and feature folders for services scoped to specific feature areas.

Angular architecture drifts into unstructured code when generic shared folders accumulate misplaced components and services. Enforcing strict src/app architecture with clear responsibilities and one-way dependency boundaries prevents this drift.
