Medi8or

Medi8or provides a simple and flexible implementation of the Mediator pattern for .NET, based on the abstractions defined in Medi8or.Abstraction.

This package includes:

  • ✅ Dependency Injection support
  • ⚙️ Two ready-to-use implementations:
    • ISender: uses reflection with caching for fast dynamic dispatch
    • IMediator: uses IServiceProvider for direct handler resolution

If you're working in a single project, installing only Medi8or is enough — it already includes a reference to Medi8or.Abstraction.


📦 Installation

dotnet add package Medi8or

✨ Features

  • Plug-and-play .AddMedi8or() extension for DI
  • Reflection-based request dispatch with internal caching via ISender
  • DI-based request dispatch with IMediator
  • Clean separation between command/query and their handlers
  • Minimal, dependency-free, and testable

🔌 Usage

Define a query and handler

public class GetUserByIdQuery : IRequest<UserDto>
{
  public string Id { get; }

  public GetUserByIdQuery(string Id)
  {
    Id = Id;
  }
}

public class GetUserByIdHandler : IRequestHandler<GetUserByIdQuery, UserDto>
{
  public async Task<UserDto> Handle(GetUserByIdQuery request, CancellationToken cancellationToken)
  {
    // Logic here
  }
}

Register via DI

builder.Services.AddMedi8or();

Automatically scans and registers all IRequestHandler<> implementations from the specified assembly.

Send the request using ISender or IMediator

// ISender use reflection
UserDto user = await _sender.SendAsync(new GetUserByIdQuery(id), cancellationToken);

// IMediator use ServiceProvider
UserDto user = await _mediator.SendAsync<GetUserByIdQuery, UserDto>(new(id), cancellationToken);

⚖️ ISender vs IMediator

Feature ISender (Reflection + Cache) IMediator (Service Provider)
Handler Resolution Uses reflection with caching Uses IServiceProvider
Performance Fast after initial reflection Fast and direct
Setup Flexibility No need to register each handler No need to register each handler
Recommended for Flexible apps, background services High-performance apps, DI-first

Medi8or.Abstraction: contains the base interfaces (IRequest, IRequestHandler<>, ISender, IMediator). Already included as a dependency — no need to install it separately for single project's solution.
