Cortex.Mediator 🧠

Cortex.Mediator is a lightweight and extensible implementation of the Mediator pattern for .NET applications, designed to power clean, modular architectures like Vertical Slice Architecture and CQRS.

Built as part of the Cortex Data Framework, this library simplifies command and query handling with built-in support for:

  • ✅ Commands & Queries
  • ✅ Notifications (Events)
  • ✅ Pipeline Behaviors
  • ✅ FluentValidation
  • ✅ Logging
  • ✅ Transaction Handling

GitHub License NuGet Version GitHub contributors Discord Shield

🚀 Getting Started

Install via NuGet

dotnet add package Cortex.Mediator

🛠️ Setup

In Program.cs or Startup.cs:

builder.Services.AddCortexMediator(
    builder.Configuration,
    new[] { typeof(Program) }, // Assemblies to scan for handlers
    options => options.AddDefaultBehaviors() // Logging, Validation, Transaction
);

📦 Folder Structure Example (Vertical Slice)

Features/
  CreateUser/
    CreateUserCommand.cs
    CreateUserCommandHandler.cs
    CreateUserValidator.cs
    CreateUserEndpoint.cs

✏️ Defining a Command

public class CreateUserCommand : ICommand
{
    public string UserName { get; set; }
    public string Email { get; set; }
}

Handler

public class CreateUserCommandHandler : ICommandHandler<CreateUserCommand>
{
    public async Task Handle(CreateUserCommand command, CancellationToken cancellationToken)
    {
        // Logic here
    }
}

Validator (Optional, via FluentValidation)

public class CreateUserValidator : AbstractValidator<CreateUserCommand>
{
    public CreateUserValidator()
    {
        RuleFor(x => x.UserName).NotEmpty();
        RuleFor(x => x.Email).NotEmpty().EmailAddress();
    }
}

🔍 Defining a Query

public class GetUserQuery : IQuery<GetUserResponse>
{
    public int UserId { get; set; }
}

public class GetUserQueryHandler : IQueryHandler<GetUserQuery, GetUserResponse>
{
    public async Task<GetUserResponse> Handle(GetUserQuery query, CancellationToken cancellationToken)
    {
        return new GetUserResponse { UserId = query.UserId, UserName = "Andy" };
    }
}

📢 Notifications (Events)

public class UserCreatedNotification : INotification
{
    public string UserName { get; set; }
}

public class SendWelcomeEmailHandler : INotificationHandler<UserCreatedNotification>
{
    public async Task Handle(UserCreatedNotification notification, CancellationToken cancellationToken)
    {
        // Send email...
    }
}

await mediator.PublishAsync(new UserCreatedNotification { UserName = "Andy" });

🔧 Pipeline Behaviors (Built-in)

Out of the box, Cortex.Mediator supports:

  • ValidationCommandBehavior
  • LoggingCommandBehavior
  • TransactionCommandBehavior

You can also register custom behaviors:

options.AddOpenCommandPipelineBehavior(typeof(MyCustomBehavior<>));
