kotlin-project-modularization

To establish Kotlin Multiplatform module boundaries, separate feature, data, app, and common modules with explicit dependency direction and visibility control. This structure enforces clear ownership and prevents cross-cutting concerns and cyclic dependencies.

Organizing Android project modules by features and data domains requires establishing explicit module types and ownership. Aligning modules with specific features and data domains while preserving platform-specific boundaries reduces coupling and improves build performance.

Yes, this modularization approach applies to both Kotlin Multiplatform and Android project structures. It guides the placement of shared code, data sources, and cross-cutting concerns across feature, data, app, and common layers for both platforms.

To control visibility of shared code and data sources in KMP modules, define explicit module boundaries and enforce dependency direction. This prevents leakage of shared code and data sources across feature, data, app, and common layers.

You need to refactor Kotlin module boundaries when a growing project experiences increased coupling, unclear ownership, or build performance issues. Realigning modules with features and data domains while enforcing explicit entry points resolves these maintainability concerns.
