Chat application by Roger Chapman
This small chat application, created using Node.js and Socket.IO; other dependencies include the express framework.
- node v0.4.10
- express v2.4.3
- socket.io v0.7.8
All dependencies should be included in the
node_modules folder, however if there are any issues with dependencies they can be installed by running:
$ npm install -d
To execute the server application:
$ node app.js <PORT>
<PORT> is specified a default port of 3000 is used.
The client can then be accessed at:
Terminal style design
The design mimics the terminal style. The user is first asked for a username, and once entered (press ENTER) the user will join the chat room. Subsequent entries/messages will be posted to all online users.
The current user's username will always appear bold for easy recognition.
User assigned color
When a user joins NodeChat they are assigned a random color for the length of their session. This color is then used whenever there username is displayed. This is helpful to pick out an individual's message when there is a large amount of users online.
As well as broadcasting a message to all online users, the user can also send a private message to any online user.
This is achieved by prefixing your message with
@username. For example:
> @roger This message will only be recived by roger
Private messages will only send messages to online users. If a user is not online a error message is displayed.
Should the server restart at anytime the client will automatically reconnect to the server (if possible). The user will re-join the chat with there current username, however they will be assigned a new color representation.
