Module 7 builds upon the JavaScript skills you learned in Module 6.

Reading

The following articles on the online class wiki textbook contain information that will help you complete the assignments.

Individual Assignments

Install Node.JS

Install Node.JS from Apt or Yum according to the instructions in the Node.JS guide.

Static File Server in Node.JS

The individual portion of Module 7 is short in order to give you enough time to complete the group portion.

  1. Copy the example code from the Node.JS guide into a file called static_server.js or something of that nature. Save it on your EC2 instance (but not in a place that Apache can serve!).
    Ensure that you understand what the static file server script is doing… this might show up on a quiz!
  2. Make a directory parallel to static_server.js named static.
  3. Change "<STATIC DIRECTORY NAME>" on line 11 of the static fileserver example code to reflect the name of the directory you just made.
  4. Save the following files in your static directory:
    <?php   phpinfo();   ?>
    
  5. Boot up your Node.JS static fileserver, and from your browser, load all four of the files you created in step 4.
    Which ones work and which ones don't? Why might this be the case?

Group Project

In the group portion of Module 7, you will be building a multiplayer, networked Pong game using Node.JS and Socket.IO. Your game must enable users to choose a nickname and play a game of Pong with others on your site without logging in (no need for a password or Open ID).

If you want to reminisce and play some Pong on the command line before building it in Node.JS, here is the command, assuming you have emacs installed:

$ emacs -q --no-splash -f pong

Press C-x C-c to exit emacs.

Instructions on how to begin your group portion can be found here: Pong Game

Grading

We will be grading the following aspects of your work. There are 75 points total.

  1. Individual Portion (20 Points):
    • Node.JS is installed on your EC2 instance (5 points)
    • The hello.txt, brookings.jpg, and city.html files all load successfully (3 points each)
    • Visiting a file that does not exist inside the static directory results in a 404 (3 points)
    • You can explain to the TA why phpinfo.php behaves the way it does when loaded through Node.JS (3 points)
  2. Pong Game (45 Points):
    • Matching Pairs of Players (10 Points):
      • Players are able to specify a name for themselves (3 points)
      • Players are able to initiate a game on their own (4 points)

      • All pages pass the W3C validator (1 point)
      • There are no XSS vulnerabilities (2 points)
      • Extra Credit: Your client.js code passes JSHint, a JavaScript validator (+3 bonus points)
