#sockets

Node.js has an under-appreciated module in its standard library that is surprisingly useful. The Readline module does what it says on the box: it reads a line of input from the terminal. This can be used to ask the user a question or two, or to create a prompt at the bottom of the screen. In this tutorial, I intend to show off the capability of Readline and make a real-time CLI chatroom backed by Socket.io. The client will not only send simple messages, but have commands for emotes with /me, private messages with /msg, and allow for nicknames to be changed with /nick.
