Dom.Mediator

Dom.Mediator is a clean, minimal, zero-dependency implementation of the Mediator pattern for .NET, focused on:

  • ✅ Request/Response messaging (CQRS)
  • ✅ Composable pipeline behaviors (validation, logging, etc.)
  • ✅ Built-in Result Pattern handling with typed errors
  • ✅ No external dependencies — just C#
  • ✅ Perfect fit for Minimal APIs or Clean Architecture

📦 Install via NuGet

dotnet add package Dom.Mediator

🚀 Quick Example

Define your command:

public class EchoCommand : IRequest<string>
{
    public string Message { get; set; } = string.Empty;
}

Create a handler:

public class EchoHandler : IRequestHandler<EchoCommand, string>
{
    public Task<Result<string>> Handle(EchoCommand request, CancellationToken cancellationToken)
    {
        return Task.FromResult(Result<string>.Success($"Echo: {request.Message}"));
    }
}

Register and send:

var mediator = new Dom.Mediator.PureMediator();
mediator.ScanHandlersFrom(Assembly.GetExecutingAssembly());

var result = await mediator.Send(new EchoCommand { Message = "Hello" });

return result.Match(
    value => Results.Ok(value),
    error => Results.Problem(error)
);

⚙️ Built-in Features

  • 🧱 Pipeline Behaviors: Add logging, validation, error handling in a clean chain.
  • 🎯 Result Pattern (Result<T> and Result): Native success/failure with structured error codes.
  • 🧪 FluentValidation Support: Easily add a validation behavior.
  • 🔄 Auto-Handler Discovery: Reflective scanning via assembly input.
  • 💡 Custom Behaviors: Plug in your own pre-/post-handling logic.

🧩 Extensibility

mediator.RegisterGlobalPipelineBehavior(typeof(MyCustomBehavior<,>));

Each behavior implements:

Task<Result<TResponse>> Handle(
    TRequest request,
    CancellationToken cancellationToken,
    RequestHandlerDelegate<TResponse> next);
