code-refactor

To safely refactor large functions, you can apply the Extract Method pattern to isolate logic into smaller helpers, reducing complexity while maintaining existing tests to validate behavior. This reduces technical debt incrementally.

Consolidating duplicated logic to reduce code smells involves identifying repeated patterns and applying targeted refactors like extracting shared methods or introducing parameter objects for better modularity.

Yes, an existing codebase with tests is required. Tests validate that applied refactoring techniques, such as replacing conditionals with polymorphism, preserve the original behavior and ensure changes are safe.

Replacing conditionals with polymorphism prepares code for extension by modularizing logic into distinct objects. This reduces complex branching, improves readability, and allows new feature additions with minimal risk.

You need a local environment to run the included refactoring scripts. The scripts propose and apply targeted changes to your codebase, requiring local execution to extract methods and introduce parameter objects.
