What problem does it solve?
Code refactoring patterns help developers improve code structure without changing external behavior, reducing technical debt and making future changes safer.
Core Features & Use Cases
- Extract Method: Break large functions into smaller, testable units.
- Extract Class: Separate cohesive concerns into dedicated classes.
- Rename and Move: Improve naming and package structure without altering behavior.
- Inline and Pattern guidance: Replace code smells with SOLID-compliant patterns.
- Use Case: when maintaining legacy code, de-risk architecture changes and improve readability with a test-first approach.
Quick Start
Provide a step-by-step refactoring plan for a given codebase, outlining smell identification, pattern selection (extract method, extract class, or rename), safe code changes, and test updates to preserve behavior.
