Minimal APIs
Design and implement Minimal APIs in ASP.NET Core using handler-first endpoints, route groups, filters, and lightweight composition suited to modern .NET services.
Trigger On
- building new HTTP APIs in ASP.NET Core
- creating lightweight microservices
- choosing between Minimal APIs and controllers
- organizing endpoints with route groups
- implementing validation and filters
Workflow
- Define endpoints directly in Program.cs (for small APIs)
- Use route groups for related endpoints
- Move handlers to separate classes as the API grows
- Apply filters for cross-cutting concerns
- Use TypedResults for type-safe responses
- Generate OpenAPI docs with
.WithOpenApi()
Deliver
- clean, organized Minimal API endpoints
- proper use of route groups and filters
- type-safe responses with TypedResults
- OpenAPI documentation
- validation with endpoint filters
Validate
- endpoints return correct status codes
- validation filters catch invalid input
- OpenAPI spec is accurate
- route groups share common configuration
- handlers are testable (can mock dependencies)
