Nodejs WebSocket chatrooms server using 'ws'

'Not so simple' handshake and everyone get's upgraded!

The server is using a 2d matrix to handle rooms and the users in each. This can be seen as a class variable in roomManager.js. I had seen other implementations for rooms such as adding the room to the user object, but this created headaches for handling simple methods like broadcast or leave-room. All client-server interaction is handled by parsing client messages over the connection.

Server features:

1. username created upon connection (bounds enforced: no whitespace, > 3 chars, < 8 chars)
2. create/join rooms
3. list current rooms and the number of users in rooms
4. chat broadcasted to users in the same room e.g 'tom35: hello'

Commands

To join a room or create if does not exist.

\r (room name)

To leave the current room.

/q

To list all rooms and the number of users in each room.
