Does node.js have any libraries for talking to SignalR Hubs?

I'd like to build a frontend web-application using node, talking to an intermediate API that's probably built with .NET tools. Since SignalR is the most likely candidate for building an HTTP Push API, I'd like to know whether there's already a library for node to talk to it, or whether I'll have to figure something out myself (I'm new-ish to both).
