1 - Introduction
A reactive website will scale and reorder elements to suit the screen size of the device being used to
access it. A dynamic website will update the elements of the page without the need for a full reload.
In this assignment you will expand upon a skeleton program in order to build a dynamic and reactive
e-commerce front end website.
2 - Learning outcomes
By the end of this assignment, you will:
Be able to implement functions using Typescript.
Be familiar with how to use React components and hooks.
Have a template website that you could expand upon for a portfolio piece.
3 - Problem description
For this task, you have been provided with a skeleton website, as well as the assets to populate it
with. At the moment the site displays the: name, picture, rating, and price of a collection of items for
sale. If you type into the search bar, it will only display items that have your search term within their
name. You must add the following functionality:
An indicator showing the number of search results or products available.
The ability to sort the items by: name, price, or rating.
The ability to show only in stock items in the search results.
Adding or removing items from the shopping basket.
Calculate the total cost of products in the shopping basket.
4 - Initial setup

Download the skeleton code included above, which is a basic e-commerce website similar to the one
shown in lectures. Ensure that you have Node.js installed on your computer, this should come with
Vite. Download the zip file of this code and extract it to a suitable place on your computer. If you do
not have a computer, connect to the Linux farm and transfer the files. Navigate to the folder in your

terminal, and type npm install. Once this installation has completed, type in npm run dev, which
should host the website locally for you. Take the localhost address shown in the output and type it
into your browser to see the website. There are 4 JSON files included in the Assets folder, which
are random products 1, 100, 150, and 175. Each of these JSON files contains a list of products to be
shown on the website. Each product has the attributes outlined in Table 1, with the images being
generated using Adobe Firefly.
Table 1: The attributes that are stored for each product
Attribute name Note
ID This is a unique identifier for each product, and is an integer.
name The name for each product.
price The price of the product in pounds.
category This is the general category of the product.
quantity
The number of this product that is currently available in stock. This is a non?negative integer.
rating This is a real number rating of the product between 0 and 5.
image_link The file location of the promotional image.
5 - Developing the website
5.1 The results indicator
When searching for products, it is often useful to know exactly how many products the current
search has returned. This can help make the website feel more reactive. In App.tsx there is a
results?indicator paragraph tag. Add a notification about how many results or products the current
search query has returned. If the search bar is empty, then the the output should be 'n Products'
where n is the number of products. If there is only a single product then the output should be '1
Product'. If the search bar is not empty, then the output should be 'm Results' where m is the number
of products returned by the search query. If there is only a single product returned by the query,
then it should say '1 Result'. If there are no results returned by a query then the output should be
'No search results found'.
5.2 Enhance search functionality
When looking at a list of products, a useful feature is being able to sort them by some attribute such
as price or rating. Add functionality to the select tag inside of the search?bar div, so changing the
selected option will result in that form of sorting being applied to the results. By default the product
list should be sorted by name alphabetically from A to Z. Once this task has been completed, add the
following functionality to the inStock checkbox input. When this checkbox is ticked, the results
should only include products that have a quantity larger than 0. Unticking this checkbox should
reverse that behaviour. Hint: this can be accomplished by using a combination of a state and a hook.
5.3 Adding to the shopping basket

2/4
Each product currently has a button underneath that says Add to basket . Update this code so that if
the quantity of available product is 0, the button instead says Out of stock and is disabled. Add a
function to
the Add to basket button that passes the information to a shopping basket variable in App.tsx. This
variable should be a list of type BasketItem. Adding multiple instances of the same product should
increase the quantity property of the relevant basket instance. Do not worry about disabling the
product s button if the quantity added to the basket is more than the quantity available. Hint: The
parent/child example given in Tutorial 4 - question 7 can give you a good starting point.
5.4 Visualising the basket
Now that the data about the basket is being collected, we should visualise it for the user. If there are
no items in the basket then the shopping ? area div should contain a paragraph text saying 'Your
basket is empty'. If the shopping basket variable contains a product, then the shopping?area div
should contain that information. Each item in the basket should be surrounded by a div with the
class 'shopping-row', and a suitable key such as the name of the item. Inside of that div there should
be another div with the class shopping-information , and a button with Remove text. The shopping?information div should contain a paragraph tag which shows the information about the product in
the format [Productname] ( [Productprice]) ? [Productquantity] eg 'Hat 4 ( 45.58) - 1'. When the
Remove button is pressed, then the quantity of that product in the basket should be reduced by 1.
If pressing that button reduces the quantity of the product to 0, then that item should be removed
from the shopping basket. Inside the shopping?area div after all of the products there should be a
paragraph tag with the total cost of the shopping basket. This should be in the form of Total:
[Totalbasketcost] eg 'Total: 45.58'. This value should be shown to 2 decimal places.
6 - Marking
Two files, App.tsx and ProductList.tsx, should be submitted through the Codegrade submission
platform. This will account for 10% of your overall module score. You may use any library that comes
with a default installation of Node.js. Your work will be submitted to an automatic
plagiarism/collusion detection system, and those exceeding a threshold will be reported to the
Academic Integrity Officer for investigation regarding adhesion to the university s policy
7 - Deadline
The deadline is 23:59 GMT Monday the 8th of May 2025. Late submissions will have the typical 5%
penalty applied for each day late, up to 5 days. Submissions after this time will not be marked.
