CandidateHubAPI

Improvements

1. Error Handling

Implement global error handling using middleware to ensure consistent error responses.

2. Validation

Add data validation annotations to the Candidate model to ensure proper data is submitted.

3. Logging

Implement logging using a logging framework like Serilog or NLog to track application behavior and errors.

4. Authentication and Authorization

Add authentication and authorization mechanisms to secure the API endpoints.

5. Asynchronous Operations

Ensure all database operations are performed asynchronously for better performance.

6. Unit Testing

Add unit tests for controllers and services to ensure code reliability and facilitate easier maintenance.

7. CORS Policy

Configure CORS policy to restrict access to the API from specific domains.

8. Pagination

Implement pagination for GET endpoints that return lists of candidates to improve performance and manageability.

9. DTOs and AutoMapper

Use Data Transfer Objects (DTOs) and AutoMapper to decouple the domain models from API models.

10. Swagger Enhancements

Add more detailed descriptions and examples in the Swagger documentation for better API usability.

Assumptions

1. The database connection string in appsettings.json is correctly configured and points to a valid SQL Server instance.
2. The Candidate model provided in the task represents the complete set of fields required.
3. The database schema does not require additional complex relationships (e.g., many-to-many).
4. The API does not need to support localization or multiple languages.
5. The current security requirements do not necessitate encryption or secure storage of sensitive fields beyond the default measures.
6. There is no requirement for performance optimizations beyond the default configurations provided by ASP.NET Core.
