design-patterns

The Gang of Four design patterns are 23 classic software architecture solutions categorized into Creational, Structural, and Behavioral types that help developers build maintainable applications.

To choose the right design pattern, consult the provided pattern selection guidance and problem-solution mapping to match your specific software architecture challenge with the appropriate GoF pattern.

To implement the Factory Method pattern in TypeScript, reference the provided quick implementation examples that offer concise code snippets for common GoF creational patterns.

You should use the Strategy or State pattern when refactoring complex code to simplify conditional logic, improve software architecture, and increase overall maintainability.

This reference includes quick implementation examples in TypeScript for common patterns like Factory Method, Strategy, Observer, and Decorator, alongside comprehensive descriptions for all 23 GoF patterns.

Creational patterns handle object creation mechanisms, Structural patterns manage object composition and interfaces, and Behavioral patterns define object interaction and responsibility assignment in software architecture.
