๐Ÿฆ– MediatRaptor

MediatRaptor is a lightweight and extensible implementation of the Mediator pattern with built-in support for CQRS (Command Query Responsibility Segregation). It is designed as a modern, minimal alternative to heavier mediator libraries, providing developers with a clean and structured way to implement Commands, Queries, Notifications, and Handlers.

The library emphasizes:

  • ๐Ÿ“ฆ Lightweight โ€“ No unnecessary dependencies, minimal overhead.
  • ๐Ÿฆ– Mediator-first โ€“ Core focus on mediator pattern with request/response pipelines.
  • โšก CQRS-ready โ€“ First-class support for commands and queries.
  • ๐Ÿ› ๏ธ Extensible โ€“ Add behaviors like logging, validation, or caching with pipeline decorators.
  • โœ… Test-friendly โ€“ Promotes separation of concerns and easy testing of handlers.

MediatRaptor is a lightweight implementation of the Mediator pattern with built-in support for CQRS (Command/Query Responsibility Segregation).
Inspired by MediatR, but built to be minimal, extensible, and fun.

โœจ Features

  • ๐Ÿฆ– Clean Mediator abstraction (IMediator)
  • โšก CQRS-ready (Commands, Queries, Notifications)
  • ๐Ÿ”— Pipeline behaviors (logging, validation, caching, etc.)
  • ๐Ÿ› ๏ธ No external dependencies โ€“ minimal and fast
  • โœ… Easy to test, extend, and integrate

๐Ÿš€ Getting Started

1. Define a Command

public record CreateUserCommand(string Username, string Email) : ICommand<Guid>;

2. Create a Handler

public class CreateUserHandler : ICommandHandler<CreateUserCommand, Guid>
{
    public Task<Guid> Handle(CreateUserCommand command, CancellationToken ct)
    {
        // business logic
        return Task.FromResult(Guid.NewGuid());
    }
}

3. Use the Mediator

var mediator = new MediatorRaptor(cfg =>
{
    cfg.RegisterHandlers(typeof(CreateUserHandler).Assembly);
});

var userId = await mediator.Send(new CreateUserCommand("hasan", "test@example.com"));
