Architecture Changes: - Replace service-based approach with CQRS handlers - Introduce IMediator for centralized request handling - Separate read operations (Queries) from write operations (Commands) Added: - MediatR package (v14.2.0) to Application layer - Query handlers for Products (GetProducts, GetProductById) - Query handlers for Categories (GetCategories, GetCategoryById) - Command handlers for Products (CreateProduct) - Command handlers for Categories (CreateCategory) --- src/CSharpApp.Api/Program.cs | 29 ++++--- .../CSharpApp.Application.csproj | 4 +- .../Commands/CreateCategoryCommand.cs | 6 ++ .../Commands/CreateCategoryCommandHandler.cs | 60 +++++++++++++ .../Categories/Queries/GetCategoriesQuery.cs | 6 ++ .../Queries/GetCategoriesQueryHandler.cs | 47 ++++++++++ .../Queries/GetCategoryByIdQuery.cs | 6 ++ .../Queries/GetCategoryByIdQueryHandler.cs | 55 ++++++++++++ .../Products/Commands/CreateProductCommand.cs | 6 ++ .../Commands/CreateProductCommandHandler.cs | 73 ++++++++++++++++ .../Products/Queries/GetProductByIdQuery.cs | 6 ++ .../Queries/GetProductByIdQueryHandler.cs | 55 ++++++++++++ .../Products/Queries/GetProductsQuery.cs | 6 ++ .../Queries/GetProductsQueryHandler.cs | 57 +++++++++++++ .../ServiceCollectionExtensions.cs | 4 + .../CSharpApp.Infrastructure.csproj | 4 +- .../Configuration/HttpConfiguration.cs | 85 +++++++++++++++++-- .../CSharpApp.Tests/CSharpApp.Tests.csproj | 2 +- 18 files changed, 489 insertions(+), 22 deletions(-) create mode 100644 src/CSharpApp.Application/Categories/Commands/CreateCategoryCommand.cs create mode 100644 src/CSharpApp.Application/Categories/Commands/CreateCategoryCommandHandler.cs create mode 100644 src/CSharpApp.Application/Categories/Queries/GetCategoriesQuery.cs create mode 100644 src/CSharpApp.Application/Categories/Queries/GetCategoriesQueryHandler.cs create mode 100644 src/CSharpApp.Application/Categories/Queries/GetCategoryByIdQuery.cs create mode 100644 src/CSharpApp.Application/Categories/Queries/GetCategoryByIdQueryHandler.cs create mode 100644 src/CSharpApp.Application/Products/Commands/CreateProductCommand.cs create mode 100644 src/CSharpApp.Application/Products/Commands/CreateProductCommandHandler.cs create mode 100644 src/CSharpApp.Application/Products/Queries/GetProductByIdQuery.cs create mode 100644 src/CSharpApp.Application/Products/Queries/GetProductByIdQueryHandler.cs create mode 100644 src/CSharpApp.Application/Products/Queries/GetProductsQuery.cs create mode 100644 src/CSharpApp.Application/Products/Queries/GetProductsQueryHandler.cs diff --git a/src/CSharpApp.Api/Program.cs b/src/CSharpApp.Api/Program.cs index 392a4f0..1278a92 100644 --- a/src/CSharpApp.Api/Program.cs +++ b/src/CSharpApp.Api/Program.cs @@ -3,6 +3,11 @@ using CSharpApp.Infrastructure; using CSharpApp.Api; using CSharpApp.Api.Validation; +using MediatR; +using CSharpApp.Application.Products.Queries; +using CSharpApp.Application.Products.Commands; +using CSharpApp.Application.Categories.Queries; +using CSharpApp.Application.Categories.Commands; var builder = WebApplication.CreateBuilder(args); @@ -37,23 +42,23 @@ var versionedEndpointRouteBuilder = app.NewVersionedApi(); -versionedEndpointRouteBuilder.MapGet("api/v{version:apiVersion}/products", async (IProductsService productsService, int? offset, int? limit) => +versionedEndpointRouteBuilder.MapGet("api/v{version:apiVersion}/products", async (IMediator mediator, int? offset, int? limit) => { - var products = await productsService.GetProducts(offset, limit); + var products = await mediator.Send(new GetProductsQuery(offset, limit)); return Results.Ok(products); }) .WithName("GetProducts") .HasApiVersion(1.0); -versionedEndpointRouteBuilder.MapGet("api/v{version:apiVersion}/products/{id}", async (IProductsService productsService, int id, CancellationToken ct) => +versionedEndpointRouteBuilder.MapGet("api/v{version:apiVersion}/products/{id}", async (IMediator mediator, int id, CancellationToken ct) => { - var product = await productsService.GetProductById(id, ct); + var product = await mediator.Send(new GetProductByIdQuery(id), ct); return product is null ?
