TinyMediator

A lightweight implementation of the Mediator pattern — with built-in source generation for automatic handler registration. Designed for minimal boilerplate and fast compile-time discovery.

Installation

via Nuget:

Install-Package TinyMediator

This will register both the mediator classes and the source-generating analyzer.

Basic Usage

  1. Define a Request and Handler
public class Ping : IRequest<Pong> { }

public class PingHandler : IRequestHandler<Ping, Pong>
{
    public Task<Pong> Handle(Ping request, CancellationToken cancellationToken)
        => Task.FromResult(new Pong());
}
  1. Register Handlers Automatically

Add this line (or equivalent) to your Program.cs and all of your IMediator implementations will be automatically registered from the generated source at compile-time.

services.AddTinyMediatorHandlers();
  1. Send Requests
var response = await mediator.Send(new Ping());

What's Inside

Component Description
IRequest<T> / INotification Core abstractions for Mediator pattern
IMediator Interface for sending requests and publishing notifications
Source Generator Auto-discovers and registers handlers at compile time
AddMediatorHandlers() Partial method generated for DI registration

Contributions

There are many, more robust libraries out there that implement the mediator pattern. I made this library for the simplest use case and wanted source generation to automate registrations without using reflection. If this is generally useful to others I might be surprised, but any suggestions or contributions are welcome.
