The URL Shortening API exemplifies

The URL Shortening API exemplifies the move toward Clean Architecture by separating business logic into a dedicated services directory.

Technical Breakdown

Structured Routing: The API is versioned (/api/v1) and utilizes a clean directory structure with separate folders for config, controllers, middleware, models, routes, and services.

Service Layer Pattern: Business logic is decoupled from the controller (e.g., urlService.js), allowing for more testable and maintainable code.

Comprehensive Documentation: The project includes a detailed README.md featuring a full API Reference, health check endpoints, and a structured table for CRUD operations (GET, POST, PUT, DELETE).

Data Integrity: Includes dedicated models and validators to ensure that every URL shortened meets strict data standards before entering the database.
