Instructions:

Code will be executed using NodeJS.

Grading is based on implementing the required functionality and coding style, specifically: clearly organized code, appropriate variable naming, code readability, coding conventions demod in class, etc.

Javascript syntax rules: Variables must be declared using let/const, not var Functions must be declared using arrow function syntax, not function() syntax When checking equality, use strict equality (triple equals ===), not double equals (==) Do NOT use higher order array functions: forEach, map, reduce, filter, closest, etc.

Unless otherwise noted, do not implement any server side or client side form field validation.

Problem Description: Using NodeJS and Express, create a server side web application for a parking lot company. Webpages The application has two client-facing HTML pages: Pay for parking: customers can purchase parking at a selected parking lot Admin login: if a user has a valid username and password, then that user can view the total amount of money collected by the parking lot. Data Store The application also contains a non-persistent data store (global array) that tracks the payments made by users to the parking lot. Payment must be represented as a Javascript object literal. Every payment contains properties for: the a users vehicle license plate the total amount paid for parking Pay for Parking Page This page is displayed when the user visits the apps default endpoint (/) The page must show: Header section that contains the webpages navigation menu Main body section that displays a form for the user to purchase parking time The form contains fields to accept data for The selected parking lot. Provide a minimum of 3 parking lots. Each parking lot must have a different hourly rate. The number of hours to park The users vehicle license plate When the form data is submitted to the server, calculate the total cost of parking, save the relevant data to the data store, and send a string response to the client. The string response must contain the users receipt. The receipt must display: The number of requested hours The hourly rate of the selected parking lot Subtotal, tax (13%), and the final amount for the user to pay Note: The maximum number of hours that can be requested is 8. If the user requests parking for more than 8 hours, send a string containing an error message back to the client. Admin Login This page is displayed when the user visits the /admin endpoint. The page must show: Header section that contains the webpages navigation menu (this menu should be identical to the menu presented on the Pay for Parking Page) Main body section that displays a form for the user to enter a username and password When the form data is submitted to the server, check that the user entered a valid administrator username and password. If the credentials are valid, calculate the total amount of fees collected by the parking lot, and send the results to the client as a string. The calculation for the total fees must be programmatically calculated based on the payment items in the applications data store (ie: loop through the array and calculate the total fees) If the credentials are invalid, send an error message to the client as a string. You may assume the only valid admin credentials are: Username: admin Password: 0000 HTML and CSS Styling For the Pay for Parking and Admin page HTML must be structured using semantic elements. You are responsible for choosing the appropriate elements for both structure and content Styling must be implemented using external CSS stylesheets. You should customize the colors and fonts. Ensure your final styling is reasonably pretty and easily readable. String data sent by the server Any string data sent by the server (error messages, receipts, etc) must be styled (HINT: Use inline styling)
