SignalR ASP.NET Core

Client – server event aggregation with SignalR ASP.NET Core

Event aggregation is really a pattern i like, there is something elegant about firing events and subscribers can listen to them without knowing who fired them. This creates decoupled domains both in backends and frontends. Back in 2013, at my customer of that time we saw an increasing demand for pub / sub and immediate update. We fired events on the backend event bus and in the frontend we had SignalR Hubs that picked up the events and forwarded them to the clients. This caused duplicated and similar code both on the client and on the web server. I decided to create an abstraction layer between SignalR and the event aggregator. The result is a library called SignalR.EventAggregatorProxy

It has now been ported to support ASP.NET Core, this article will focus on the changes, for the orginal article go here.
