### Key Design Patterns

- **Factory**: `CrawlerClientFactory`, `ExtractorFactory` - protocol/format-specific component selection
- **Strategy**: `CrawlerClient`, `Extractor`, `Transformer` - pluggable implementations
- **Builder**: `RequestDataBuilder`, `ExtractorBuilder` - fluent construction

En el tutorial principal leíste cómo agregar [Middleware Personalizado](../tutorial/middleware.md) a tu aplicación.

Y luego también leíste cómo manejar [CORS con el `CORSMiddleware`](../tutorial/cors.md).

En esta sección veremos cómo usar otros middlewares.

### Створіть залежність сесії { #create-a-session-dependency }

**`Session`** зберігає **об’єкти в пам’яті** та відстежує зміни у даних, а потім **використовує `engine`** для взаємодії з базою даних.

Ми створимо **залежність** FastAPI з `yield`, яка надаватиме нову `Session` для кожного запиту. Це й гарантує, що ми використовуємо одну сесію на запит. 🤓
