// This server will start a bash shell and expose it | |
// over socket.io to a browser. See ./term.html for the | |
// client side. | |
// | |
// You should probably: | |
// | |
// npm install socket.io | |
// curl -O https://github.com/LearnBoost/Socket.IO/raw/master/socket.io.min.js | |
// | |
// To get socket.io in the node_modules directory and | |
// the socket.io.min.js file needed for the client. | |
// | |
// To start the server: | |
// | |
// node server.js | |
// | |
// And then load up your term! | |
// | |
// open http://`hostname`:8080/term.html | |
// | |
// You can even share the url with a friend on your | |
// local network. Be sure they're a friend though :-) | |

I refactored it with Express (in a quick and dirty way) and updated the method calls of socket-io.
See: https://github.com/melvinroest/browserbash
What's the license? Is it MIT? Then I can incorporate it as well :)
