Slipway by Factor House is now open-source and published to Clojars:
Slipway is a Clojure companion to embedded Jetty with websocket support.
We take great utility from Jetty in our product. Over time our requirements out-grew the libraries that are currently available in this space, so we built our own.
Hopefully our experience is useful in the broader Clojure community.
Best (and happy holidays),
Derek
