Raptor.Common 0.0.10

Common Library (Raptor.Common)

Reusable library for building clean, decoupled, and resilient APIs on .NET 8.

Overview

This package provides:

• Result modeling (Result, SuccessResult, FailureResult)
• Error wrappers (BusinessRuleException, ErrorList)
• Clean Architecture interfaces (IInteractor, IPresenter, IResponse, etc.)
• Centralized HTTP client (HttpApiClient)
• Logging extensions for Serilog + Seq

Installation

Install from NuGet:

dotnet add package Raptor.Common

Or add to your .csproj:

<PackageReference Include="Raptor.Common" Version="x.y.z" />

Replace x.y.z with the latest version from NuGet.

Requirements

• .NET 8 SDK (net8.0)
• Compatible with ASP.NET Core, domain libraries, and microservices

Project structure (updated paths)

The library now lives at Common/ (previous nested paths were flattened).

Common/                      core library
  CleanArch/                 clean architecture abstractions
  Infra/HttpApi/             HTTP API client and responses
  Logging/                   Serilog + Seq extensions
  Users/                     sample user domain helpers
Common.Tests/                tests
Common.sln                   solution
Common/version               version source for packaging

Usage

Result modeling

using Common;

Result<string> ok = Result.OK("All good");
Result<string> error = Result.Fail<string>("Something went wrong");

Clean Architecture interactor

using Common;
using Common.CleanArch;

public class GetUserInteractor : IResultInteractor<GetUserRequest, UserDto>
{
    public Task<Result<UserDto>> Handle(GetUserRequest request, CancellationToken cancellationToken)
    {
        if (request.Id <= 0)
            return Task.FromResult(Result.Fail<UserDto>("Invalid ID"));

        var user = new UserDto { Id = request.Id, Name = "Example" };
        return Task.FromResult(Result.OK(user));
    }
}

Centralized HTTP client

using Common.Infra.HttpApi;

var client = new HttpApiClient("https://api.example.com/");
var response = await client.GetAsync<MyResponse>("endpoint");

Logging (Serilog + Seq)

appsettings.json:

"CustomLogging": {
  "Project": "MyApiProject",
  "SeqUri": "http://localhost:5341",
  "LogEventLevel": "Information"
}

Registration:

using Common.Logging;

builder.Services.AddLoggingServices(configuration);

Versioning and releases

• PackageId: Raptor.Common
• Version source: Common/version (used by Common/Common.csproj)
• Recommended tags: vX.Y.Z (matching the NuGet package version)

Release checklist

1. Update Common/version and CHANGELOG.md.
2. Run dotnet test Common.sln.
3. Run dotnet pack Common/Common.csproj -c Release.
4. Tag the commit: git tag vX.Y.Z.
5. Push branch and tags.

Git flow (adjusted)

• main: stable, published code
• develop: integration branch
• feature/*: new work
• fix/* or hotfix/*: urgent fixes
• legacy/*: legacy snapshots (for example legacy/common-legacy)
• Release tags: vX.Y.Z
