B2aTech.CrossCuttingConcern

A lightweight modular library for adding permission-based authorization, user context extensions, and configurable permission caching into ASP.NET Core projects.

Designed for .NET 9+ applications with clean dependency injection and easy configuration.

✨ Features

  • Dynamic Permission Authorization Handler
    • Attribute-based permission checks using [RequiresPermissions].
    • Supports organization and user-specific permissions.
  • PermissionService
    • Caches permissions with sliding expiration.
    • Supports parent-child permission hierarchy lookup.
    • Configurable detailed logging (for debugging scenarios).
  • HttpContext Extensions
    • GetDhanManUserId() utility to extract user ID from claims.
  • Configurable Logging
    • Control verbose logging via EnableLogging flag from appsettings.json.
  • Designed for NuGet
    • Clean separation for easy plug-and-play.

🚀 Installation

Install via NuGet (once published):

dotnet add package B2aTech.CrossCuttingConcern

Or reference it manually via your .csproj:

<PackageReference Include="B2aTech.CrossCuttingConcern" Version="x.y.z" />

⚙️ Setup Instructions

In your Program.cs or Startup.cs, register services:

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextAccessor();
    services.AddMemoryCache();

    services.Configure<PermissionServiceOptions>(Configuration.GetSection("PermissionService"));
    
    services.AddScoped<IPermissionService, PermissionService>();
    services.AddScoped<IAuthorizationHandler, DynamicPermissionHandler>();

    services.AddAuthorization(options =>
    {
        options.AddPolicy("DynamicPermissionPolicy", policy =>
        {
            policy.Requirements.Add(new PermissionRequirement());
        });
    });
}

📄 appsettings.json Configuration Example

{
  "PermissionService": {
    "EnableLogging": true
  }
}
  • EnableLogging:
    • true: Detailed logs during permission checks.
    • false: Suppress logging output.

🧩 Usage Example

  1. Decorate your API endpoints with required permissions:
[Authorize(Policy = "DynamicPermissionPolicy")]
[RequiresPermissions("Dhanman.Community.Facility.Create", "Dhanman.Community.Facility.Read")]
[HttpGet("api/facilities")]
public IActionResult GetFacilities()
{
    // Only users with the required permissions can access this endpoint
    ...
}
  1. The library will automatically:
    • Extract x-organization-id from request headers.
    • Extract dhanmanId from user claims.
    • Check against cached permissions.
    • Allow or deny based on configuration.

📦 Requirements

  • .NET 9.0 or higher
  • ASP.NET Core application (using Endpoint Routing)
  • Must reference Microsoft.AspNetCore.App via FrameworkReference (default for Web Apps)
