Usage

• For eventstream and websockets use thin as your webserver
• install dependencies in run.rb with $ bundle install
• Run server $ ruby run.rb
• navigate browser to 127.0.0.1:4567

Limitations

• Uses EventSource rather than WebSockets, so STDIN can't be sent to terminal after issuing a command (see screenshot for examples of what can be done)
• Will format for ANSI characters, but won't print special characters (clear terminal, modify existing input, etc)
• This grants full access to the terminal. Nefarious users can execute anything they can access in a terminal

Environment

• Built on Ruby 2.5.0 on MacOS and Linux
