Modelet e dizajnit nuk janë thjesht akademike — ato janë të integruara në të gjithë kornizat reale, bibliotekat dhe bazat e kodit. Njohjja e modeleve në mjetet që përdorni thellëson kuptimin dhe tregon vlerën e tyre praktike.
Modelet në kornizat popullore
✓ OBSERVER → React's reactivity, RxJS, event emitters, state management (subscribe to changes)
✓ DEPENDENCY INJECTION → Spring, Angular, NestJS (inject dependencies, IoC containers)
✓ DECORATOR → middleware, React HOCs, Python/TypeScript decorators, I/O stream wrapping
✓ FACTORY → object/component creation in many frameworks/libraries
✓ STRATEGY → pluggable algorithms (sorting comparators, auth strategies like Passport)
✓ SINGLETON → app-wide services, configuration, connection pools
✓ PROXY → ORMs (lazy loading), JS Proxy, API clients, caching proxies
✓ MVC/MVVM → web frameworks (Rails, Django, ASP.NET); MVVM in UI frameworks (data binding)
