solid-principles

To apply SOLID principles in TypeScript, use specific design patterns to ensure single responsibility, open/closed, Liskov substitution, interface segregation, and dependency inversion. This Skill provides explanations and TypeScript examples for each principle to guide your implementation.

Common violations of SOLID design principles include typical anti-patterns that reduce maintainability and flexibility. This Skill identifies these frequent mistakes and provides a checklist of questions to ask during code reviews to ensure compliance.

You need to refactor code using object-oriented design patterns when your existing implementation lacks extensibility and maintainability. Consulting SOLID principles during module design or refactoring helps ensure codebases remain flexible and understandable.

The best way to ensure maintainability and flexibility when designing a new module is to adhere to SOLID principles. Following these object-oriented design guidelines prevents rigid code structures and promotes long-term extensibility.

This SOLID principles guidance addresses general object-oriented design concepts but provides concrete implementation examples in TypeScript. The underlying design patterns and maintainability checklists apply broadly to any object-oriented codebase.
