Writing a Server Application Tasks In this task you are asked to demonstrate how a web server can be coded to serve dynamic pages. Specifically, the server application is to provide a page that displays if the visitor is a Winner of a Competition or not. The selection of a win/no-win can be based on a simple random number selection (i.e., 1 in 3 chance). This page is to be served through a defined web address (or route) such as http://localhost: 3000/competition. Follow the steps below to complete this task: 1. Create your own local directory (or you can use the same local directory created in Task 8.1). 2. Use express module to create a Node.js application (i.e., using the index.js from your Task 8.1 or creating a new expressserver.js) that will set a local web server. The server listens to the port 3000. 3. Modify your index.js (or expressServer.js) file to: o remove the hardcoded response for the GET on the route (as done in Task 8.1P) and change it to serve pages form the public_html folder, as done in previous weeks (sample of this code is shown in the snippet below) o add a route handler for a GET request on /competition. This would enable access to http://localhost: 3000/competition using a web browser. The handler for this route would then choose a random number (say out of 3) and if it equals 3 then display a 'win', otherwise display a 'no win' message. These messages, along with a statistics (tally) of wins & losses, should be provided a new webpage. 4. Run the command node. (to run the index.js) or node expressServer.js in a Command Prompt (Windows) or Terminal (Mac OS) within your local directory to make the server work. 5. Use the provided index.html file to access your newly created /competition route handler (or access it directly through http://localhost: 3000/competition), the Home page should appear like this:

Chapter 2: Summary Hands-On Practice Case Study Task 1: The Website Folder. Create a folder on your hard drive or portable storage device (thumb drive or SD card) called "yoga" to contain your Path of Light Yoga Studio web page files. Task 2: The Home Page. You will use a text editor to create the Home page for the Path of Light Yoga Studio website. The Home page is shown in Figure 2.46. Task 3: The Classes Page. Create the Classes page shown in Figure 2.47. A technique that improves productivity is to create new pages based on existing pages so that you can benefit from your previous work. Your new Classes page will use the index.html page as a starting point. Open the index.html page for the Path of Light Yoga Studio website in a text editor. Select File > Save As, and save the file with the new name of classes.html in the yoga folder. Now you are ready to edit the page. 1. Web Page Title. Modify the page title. Change the text contained between the <title> and </title> tags to the following: Path of Light Yoga Studio :: Classes 2. Wireframe Main Content. a. Delete the Home Page content paragraphs, unordered list, and contact information. b. Configure the following text in the heading 2 element: Yoga Classes
