Guacamole.Mediator

A minimal mediator for .NET that dispatches requests to scoped handlers resolved from the DI container.

Install

dotnet add package Guacamole.Mediator

Register

// Scan a single assembly
builder.Services.AddMediator(typeof(GetUserHandler).Assembly);

// Scan multiple assemblies
builder.Services.AddMediator(
    typeof(GetUserHandler).Assembly,
    typeof(OrderHandler).Assembly);

All IRequestHandler<TRequest, TResponse> and IRequestHandler<TRequest> implementations found in the scanned assemblies are registered as scoped services automatically. IMediator is also registered as scoped.

Define a request and handler

// Request with response
public record GetUserQuery(Guid Id) : IRequest<UserDto>;

public class GetUserHandler(IUserRepository repo) : IRequestHandler<GetUserQuery, UserDto>
{
    public async Task<UserDto> Handle(GetUserQuery request, CancellationToken ct)
        => await repo.GetByIdAsync(request.Id, ct);
}

// Fire-and-forget
public record DeleteUserCommand(Guid Id) : IRequest;

public class DeleteUserHandler(IUserRepository repo) : IRequestHandler<DeleteUserCommand>
{
    public async Task Handle(DeleteUserCommand request, CancellationToken ct)
        => await repo.DeleteAsync(request.Id, ct);
}

Send

// Inject IMediator
var user = await mediator.Send(new GetUserQuery(id), ct);  // returns TResponse
await mediator.Send(new DeleteUserCommand(id), ct);        // fire-and-forget

Error handling

If no handler is registered for a request type, Send throws InvalidOperationException with a diagnostic message naming the missing handler interface:

No handler registered for request type 'GetUserQuery'.
Ensure you called AddMediator() and the handler implements IRequestHandler<GetUserQuery, UserDto>.
