Architecture

The application follows a layered architecture:

• Controller Layer: Handles HTTP requests and responses.
• Service Layer: Contains business logic and interacts with repositories.
• Repository Layer: Manages data persistence using Spring Data JPA.
• Entity Layer: Defines the data models for components, users, suppliers, etc.
• Security Layer: Manages authentication and authorization using JWT.
• Integration Layer: Connects to external APIs (e.g., DigiKey).

Main Packages

• controller/: REST controllers
• services/: Business logic
• repositories/: Data access
• entities/: Data models
• security/: Security configuration

Data Flow

1. Request received by Controller
2. Controller calls Service
3. Service interacts with Repository
4. Repository accesses Entity
5. Response returned to client
