Tubesock is a little utility that pipes STDIN to a WebSocket (and back again).

$ npm install -g tubesock

Pipe random numbers to tubesock:

$ while true; do
  ruby -e "puts rand(30) + 50";
  sleep 1;
  done | tubesock

Then you can read the data coming from the WebSocket:

ws = new WebSocket('ws://localhost:9999')
ws.onmessage = function () { ... }

Here it is connected to a graph:

The port to open the WebSocket server on. Default 9999.

The port to open the WebSocket server on. Default true.

As long as you don't set --send-options to false, any additional options you pass to tubesock will be sent to new client connections.

Do it!
