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:

Include a Button object that when clicked modifies the content of the page to display an appropriate greeting message. o The current time of day should be used to personalise the message, for example, Good Morning, Good Day, Good Afternoon, or Good Evening) along with the input name (e.g., "Good Morning Michael") based on the hour of the day. • Also include the time and date, showing the number of hours and minutes into the day, along with the day of the week, date, month and year; as shown below. 3. Implement the onmouseover event handler for the welcome message paragraph to change the style of the welcome paragraph (background colour to yellow). 4. Implement onmouseout effects to change the style of a paragraph back to its original background colour. What will you submit?
