I needed a generic way of listening to server side events on the client, I created this little SignalR proxy
Install through nuget
Its very easy to setup look at the wiki
Install .NET Client through nuget
Hope to get feedback on improvements etc, thanks.

Lib refactored, moved constraint part of library to seperate assembly.
I did this because its highly likly you want to design your system in a way that you constraint event propagation from a lib that should not know about SignalR (Backend, domain, CQRS store, etc). The constraint lib has no dependecy to SignalR and can be
installed using nuget

New version on nuget
You can now use Generic events like
signalR.eventAggregator.subscribe(MyApp.Events.MyGenericEvent.of("System.String"), this.onMyGenericEvent, this);
that will let you return all generic argument types.

new version out for a few days, small change but important neverless, you can now use Covariant declared generic events.

Added a .NET Client
It requires version 0.3.33 or later of the server library
Subscribe to a event like
public class MyViewModel : IHandle<MyEvent>
public MyViewModel(IEventAggregator eventAggregator)
public void Handle(MyEvent message)
//Act on MyEvent

New version 1.0.51
New Versio of .NET client 1.0.53
Aug 22, 2013 04:24 AM|Anders Malmgren|LINK
Introduced a edge case bug with 1.0.51
It was caused by a third party library (Knockout Validation) found its way into the client libraries subscription queue and recurisvly iterate it, since each subscription has a reference to the subscriber the library went into a infinite loop and stack overflowed.
I made a closure around the subscription queue so no third party library should be able to find its way into our subscription queue.
Download 1.0.57 for fixed version

This release fixes a problem with multiple subscriptions of same type of event from the same client. Lets say you have two components (ViewModels etc) that listens to the same event (Standard event, generic event with same generic parameters or constrained
event with same constraint).
With the the old solution this would result in one subscription to server per client side subscription. Meaning that when the server side event fires it will fire as many times as the client subscribed. This will result in that the subscribers client side
will recevice the event multiple times, for 2 subscriptions you will get 4 client side event triggers.
When you unsubscribe a component client side all components listen to that same event will be unsunscribed server side.
This version fixes both subscribe and unsubscribe
New version 1.1.67
New Version of .NET client 1.1.77

New versions of both Server and .NET client, only change is to support SignalR 2.0. One small change for setup, in your 2.0 Config method do
public static void Configuration(IAppBuilder app)

There was a bug introduced in 1.1.67 that I noticed first now, it shows if you have a generic event that you listen to multiple times but with different generic paramers and they have the same constraint.
This is fixed in version 1.2.99 for SignalR 2.0 and version 1.1.85-SignalR-1x for SignalR 1.x

Fixed a minor edge case bug with contraint handling. You can now have one Contraint that handles all Events. I wrote a blog about what that can be good for
Also I've published a Live demo for the API here

New version, biggest change is that we Separated core and SystemWeb parts of the library.
If you host under ASP.NET install

Finally got around to port this library to ASP.NET Core. Install using

The plugin is super easy to use. Just install it using unpkg: signalr.eventaggregatorproxy.vue
Install it in Vue: Vue.use(signalR);
You can now listen to server side events from your vm by calling
Or publish clent side events by doing
The plugin unsubscribes itself when the vm is destroyed so the dev can worry about other stuff
