Generic Web Apis

CRUD support for (Minimal) WebAPIs with the power of Mediator pattern, Automapper, DataRepositories and Entity Framework

This CleanCodeJN package uses build-in Command-Abstraction to use basic CRUD operations with the ability to customize complex business logic by the power of the the Integration/Operation Segregation Principle.

Features

• CRUD APIs build in seconds
• Uses Mediator to abstract build-in and custom complex business logic
• Uses DataRepositories to abstract Entity Framework from business logic
• Enforces IOSP (Integration/Operation Segregation Principle) for commands
• Easy to mock and test
• On latest .NET 8.0

How to use

• Add RegisterRepositoriesCommandsWithAutomapper() to your Program.cs
• Add app.RegisterApis() to your Program.cs
• Start writing Apis by implementing IApi
• Extend standard CRUD operations by specific Where() and Include() clauses
• Use IOSP for complex business logic

Step by step explanation

Add RegisterRepositoriesCommandsWithAutomapper() to your Program.cs:

builder.Services.RegisterRepositoriesCommandsWithAutomapper<MyDbContext>(cfg => { cfg.CreateMap<Customer, CustomerPutDto>().ReverseMap(); cfg.CreateMap<Customer, CustomerPostDto>().ReverseMap(); cfg.CreateMap<Customer, CustomerGetDto>().ReverseMap(); });

Add app.RegisterApis() to your Program.cs:

app.RegisterApis();

Start writing Apis by implementing IApi:

public class CustomersV1Api : IApi { public List<string> Tags => ["Customers V1"]; public string Route => $"api/v1/customers"; public List<Func<WebApplication, RouteHandlerBuilder>> HttpMethods => [ app => app.MapGet<Customer, CustomerGetDto>(Route, Tags), app => app.MapGetById<Customer, CustomerGetDto>(Route, Tags), app => app.MapPut<Customer, CustomerPutDto, CustomerGetDto>(Route, Tags), app => app.MapPost<Customer, CustomerPostDto, CustomerGetDto>(Route, Tags), // Or use a custom Command with MapRequest app => app.MapDeleteRequest(Route, Tags, async (int id, [FromServices] ApiBase api) => await api.Handle<Customer, CustomerGetDto>(new MyOwnDeleteRequest { Id = id })) ]; }
