Hi Gustaf,
I’ve noticed you had uploaded a simple client interface to
websocket-procs.tcl.
https://bitbucket.org/naviserver/websocket/src/master/websocket-procs.tcl
<https://bitbucket.org/naviserver/websocket/src/master/websocket-procs.tcl>
However, I hit another error related to [dict], because the url doesn’t return
a path, when [dict get $d path] runs.
The websocket sample is "wss://javascript.info/article/websocket/demo/hello"
Best wishes,
I
