RESTworld.Business 4.0.1

RESTworld

RESTworld is a framework which utilizes other common frameworks and patterns alltogether to enable easy and fast creation of a truly RESTful API.

Used frameworks and patterns

• Entity Framework Core for data access
• ASP.Net Core for hosting
• HAL for providing hyperlinks between resources
• OData for query support on list endpoints
• AutoMapper for mapping between Entities and DTOs
• Resource based authorization
• API Versioning through media types

Pipeline

The most basic pipeline has the following data flow for a request on a list endpoint:

1. Request
2. Controller selection through ASP.Net Core (optionally with versioning)
3. Query parsing through OData
4. Controller method calls business service method
5. Authorization validates and modifies the request (both optional)
6. Service validates that all migrations have been applied to the database, to protect from locks during migration.
7. Service gets the data through Entity Framework Core
8. Entity Framework Core translates the query into SQL and gets the data from the database
9. Business service translates Entities into DTOs through Automapper
10. Authorization validates and modifies the response (both optional)
11. Controller wraps the result in a HAL response
12. Result

Usage as API developer
