Code:

using Mux
using JSON

function websocket_service(x)
# No key :socket found in x !
println(x)
sock = x[:socket]
while !eof(sock)
str = String(read(sock))
println("Received data: " * str)
json = JSON.parse(str)
# Call to POWERED II Model with Json Observations
write(sock, "Here are the predictions" * str)
end
end

WebSocket server

@app w = (
Mux.wdefaults,
route("/ws_io", websocket_service),
Mux.wclose,
Mux.notfound());

# Serve both servers on the same port.

wait(serve(w, 8000))

from mux.jl.

Ok I got it workings. Turns out the Websocket server isn't a standalone service, you also need the HTTP server to host the socket!

from mux.jl.

Great!

The README.md contains a complete example of how to do this, but I suppose it could be clearer that Mux (WebSockets.jl) expect a regular HTTP server and a WS server.

Please feel free to make a PR changing the README if you think it helps :)
