I think I saw this early on, but then forgot about it. Stumbled upon it today, and it actually looks like a cool project. Have anyone any experience of using it for a real or just a toy project?

Ok, so it sounds like our controller is doing the mediator role, and our web framework (with the middleware and whatnot) is doing your controller work.

Our project is in Python with Flask, and Flask + middleware handles general stuff (authentication, parsing headers, etc), which is common for most requests, and then the controller loads the metadata into structures (JSON, query params, etc) with basic validation (ranges, values for enums, etc), and the service takes it from there.

AspNetCore works very much the same.

The mediator pattern is a little different though. It doesn't talk to the service directly.

The controller creates a request object and passes it to the mediator. The mediator finds the correct handler and invokes it. The result is then returned to the controller.

It essentially completely decouples the controller from the service.

Ah, makes sense. Thanks!
