To organize Rails apps into modular packages, you scaffold engine-based feature packages for reusable domain logic and portal packages for web interfaces, integrating them via config/packages.rb to auto-load package engines.

Feature packages in Rails contain reusable domain logic like models and policies for sharing across portals, while portal packages hold portal-specific web interfaces such as controllers, views, and routes for admin or dashboard interfaces.

You scaffold reusable domain logic and web interfaces in Rails by using generator commands to create feature and portal packages, which structure code into auto-loaded engines with proper namespacing for clean separation.

Yes, you can share business logic across multiple portals in a Rails application by extracting it into reusable feature packages that contain domain models, definitions, policies, and interactions separate from portal-specific web interfaces.

Organizing Rails code into modular packages uses an engine-based architecture to ensure proper namespacing and clean separation, auto-loading package engines through config/packages.rb for reusable components across multiple portals.

You should avoid a modular package architecture for Rails apps that do not require reusable domain logic or multiple web interfaces, as scaffolding engine-based feature and portal packages adds structural overhead better suited for larger codebases.
