How do I interface with websockets as a client using Immutant?

Question

I'm building a Clojure app that needs to interface with Slack's real time API, and that requires a connection to a Websocket.

I am aware this is possible with gniazdo, but this pulls in Jetty, and I believe that Immutant has its own Websocket abstraction.

I've also tried using clj-http, but it does not recognise the wss:// protocol, which is the URL returned from the Slack API.

Would greatly appreciate it if I were pointed in the right direction. Thanks!

Immutant uses Undertow as it's web server, which provides the wss protocol support you seek. Sadly, looking through the Immutant clojure wrapper code I don't see any part touching this functionality, so you will have to use Clojure's Java interop facilities.

The relevant source seems to be implemented here.

Thanks. I'll probably look at other web servers like Aleph. – jethro kuan Jan 12 '16 at 13:12
This is correct - Immutant only implements websockets on the server side, and provides no client. – Toby Crawley Jan 12 '16 at 13:34
