8.2C: 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 .
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:
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)
add a route handler for a
GET
request on
/competition
. This would enable
access to 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,
