Flowify - a simple and straightforward mediator and dispatching library for .NET 9+. Flowify helps decouple requests from handlers, promoting clean architecture and separation of concerns. It's a free, lightweight alternative to MediatR.

Features

• Commands - With or without return values
• Queries - Retrieve data efficiently
• Notifications - Publish events to multiple handlers
• Automatic Handler Registration - Scan assemblies and register handlers automatically
• MediatR-Compatible - Same interfaces for easy migration

Roadmap

• v0.5: Flowify acts as a replacement for MediatR and can be used to send requests and dispatch events (notifications).
• v0.6: Pipeline middleware for handling cross-cutting concerns.
• v0.7: Pipeline middleware with an out-of-the-box solution for chaining handlers (Chain of Responsibility).
• v0.8: Fire-and-forget support with in-memory messaging.
• v0.9: Parallel processing with configurable parallelism options, enabling strict control over system resources.
• v1.0: First stable release of the product.
• v2.0: Messaging and event dispatching support for Entity Framework, MongoDB, RabbitMQ, and Azure Service Bus.

Quick Example

using Flowify;
using Microsoft.Extensions.DependencyInjection;

// Define a command
public record CreateUserCommand(string Name, string Email) : IRequest<int>;

// Create a handler
public class CreateUserHandler : IRequestHandler<CreateUserCommand, int>
{
    public Task<int> Handle(CreateUserCommand request, CancellationToken cancellationToken)
    {
        // Your business logic here
        var userId = SaveUser(request.Name, request.Email);
        return Task.FromResult(userId);
    }
}

// Setup DI and use
var services = new ServiceCollection();
services.AddFlowify(typeof(Program).Assembly);
var provider = services.BuildServiceProvider();
var mediator = provider.GetRequiredService<IMediator>();

// Send command
var userId = await mediator.Send(new CreateUserCommand("John Doe", "john@example.com"));
