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


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

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:
    • hello.txt, a text file containing "Hello World"
    • skyline.jpg, an image file you can download from here: TODO
    • city.html, an HTML document based on the Quick and Easy HTML Layout containing an image tag pointing to skyline.jpg
    • phpinfo.php, a PHP file containing the phpinfo command that generates a diagnostic page of the server:
    <?php   phpinfo();   ?>
  5. Boot up your Node.JS static fileserver and 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?

      • Site is visually appealing (1 point)
  2. Creative Portion (15 Points) (see below)

Creative Portion

This module, and all future modules, will require that you invest some time into creating additional features for your group project. Plan to invest at least 60 minutes of your time into the creative portion.

  • The creative portion is an opportunity for you to learn material of your own interest.
  • You will not earn credit for a creative-portion feature that simply rehashes something you've already done in a previous module.

If you need ideas for a creative portion, or if you want to know whether or not your creative portion idea is "hard enough", ask a TA.
