A basic unsecure, public chatroom to test socket.io with several features:

1. a way to capture and save the username of every client that connects to the server,
2. A notification system that announces to all clients whenever a user enters or leaves the chat, as well as a report of all the users still connected
3. A way to make sure the same user isn’t logged in twice (and not allow the second attempt)
4. Ability to log in to different rooms

1. Express + Node
2. socket.io

1. Download the repo & run npm i
2. Run node server.js
3. Go to localhost:3000 on several different browser tabs, "logging in" as different usernames on each one
4. Send a message from any tab and see it appear on the others
5. To test the rooms feature, go to localhost:3000/rooms/room_name and replace room_name with whatever room you want to create

1. The Express server is contained in server.js
2. The client is contained in client.html (including JS)
