Nordic APIs·44wWhat is Code Refactoring?
Code refactoring involves restructuring existing code without changing its functionality to improve readability, maintainability, and performance. The practice is particularly crucial for APIs where performance and reliability are paramount. Refactoring can reduce execution time by 15%, decrease complexity by 30%, and speed up developer onboarding by 62%. Key best practices include following the DRY principle, implementing comprehensive testing before refactoring, favoring composition over inheritance, and making incremental changes rather than major overhauls. The article demonstrates these concepts through Flask API examples, showing how poorly structured code can be transformed into clean, efficient, and maintainable systems.
