To eliminate duplicated logic across multiple modules, you extract the shared implementation into a single reusable component and update all existing call sites to reference it. This consolidation reduces maintenance costs and prevents bugs.

Refactoring code to follow the DRY principle involves detecting identical logic in several locations, extracting a single shared implementation into a new module, and updating all call sites to use this consolidated component.

You need to extract shared logic into reusable modules when you identify the same algorithm or pattern used in multiple files across multi-module projects. This refactoring simplifies future updates and minimizes code duplication.

After extracting shared logic into a new module, you update all call sites by replacing the local duplicated implementations with references to the newly extracted shared component. You must then verify behavior with tests to ensure functionality remains intact.

Yes, DRY code refactoring applies to multi-file and multi-module projects where identical logic exists in several locations across modules or services. It detects duplication and consolidates it into a single shared implementation.
