for more, have a look insrc/socketcluster_clj/<ns>.clj to learn what else you can call.
if you get the following error when trying to connect:
Exceptionin thread"OkHttp Dispatcher" java.lang.NullPointerExceptionat io.github.sac.Socket$1.onFailure(Socket.java:185)at okhttp3.internal.ws.RealWebSocket.failWebSocket(RealWebSocket.java:546)at okhttp3.internal.ws.RealWebSocket$2.onResponse(RealWebSocket.java:206)
you need to(sc-listen/set-listener <socket>)before connecting.
