TinyPubSub makeover - arguments and new super hero publish features

I finally got around to give TinyPubSub a well deserved make over by adding some features that have been requested for a while. The toughest part is to keep it Tiny and not add to much bells and whistles to it.

I also got some great help from my friend Daniel Hindrikes to set up a devops flow that will help me manage pull requests and nuget-package publishing.

The features added to this version are;

  • Publish with arguments
  • Publish using fire-and-forget (with or without argument)
  • Publish async (with or without argument)

Publish with argument


You can now subscribe and pass an argument of the type Action<string>:

  TinyPubSub.Subscribe("test", (x) => Log.WriteString(x));

And publish it by simply adding another argument:

  TinyPubSub.Publish("test""duck");

In order to keep it tiny we only allow for a single string argument at the moment. We did explore a whole bunch of alternatives, including generics and dynamic objects and stuff but we settled for this at the moment.

Publish using fire and forget (PublishAsTask)


Using a simple Publish in TinyPubSub is synchronous and will stop the execution flow until all the subscribers have executed their code. We've now added a way to publish events fire-and-forget style.

  TinyPubSub.PublishAsTask("test""duck");

Publish async


And the last way is to simply publish async. Works as expected.

  await TinyPubSub.PublishAsync("test""duck");
