This directory contains an echo websocket server.

It authenticates with a token in header.

# ## wait for server to start
# listening on http://127.0.0.1:5000
# ## authenticated with a hardcoded token in header
# ## now you can type like echo command
# Connected (press CTRL+C to quit)
# > echo 
# < echo
# > test
# < test
# > kjlfads
# < kjlfads
# > failed to echo with 127.0.0.1:50214: failed to get reader: received close frame: status = StatusNoStatusRcvd and reason = ""
# Terminated

How to play with websocket

Use wscat to connect to a WebSocket API and send messages to it

Or use hashrocket/ws, but it doesn't support sub-protocol.
