How do you build an e-commerce website in 2 days?

For this project, I was given the following requirements:

Item Management

The website can show different items in a shop, including name, description, price and quantity.

User Management

The website should have user accounts to track customer information and orders.

Cart Management

There should be a cart which acts as a temporary item cache before the final purchase.

Category Filtering

Customers should be able to discover items by category

The Ok Store

I decided to build a back-end API server that would serve information to a front-end web page.

My API server has the following features:

• Junction tables for data in many-to-many relationships (users/items, items/categories)
• Complete endpoints with full CRUD operations for all data types
• JWT tokenization for stateless session management

My front-end webpage has the following features:

• State management with Redux
• Login and register page for existing / new users
• Item catalog with add to cart feature
• Cart preview displaying total amount and number of items
• Cart with 'remove from cart' and send order features

Getting Started

Setting up requires running two concurrent servers for front-end and back-end.

In one terminal, run:

cd back-end
export FLASK_APP=app.py
flask run

In another terminal, run:

cd front-end
npm start

Testing

The database is pre-loaded with user accounts with you can use to login. You can also choose to register new accounts in the login page.

Username: admin Password: admin

Also, in certain browsers like Chrome, localhost CORS requests are disallowed by default. To bypass this issue, you can simply download a CORS web extension to enable cross-origin resource sharing for development testing purposes.

Built With

• React - Front-end web framework used
• Redux - State management framework used
• Flask - API server framework used

Notes

Due to time constraints, I was unable to complete the categories feature. However, the back-end structure is already set in place, with specific category endpoints returning a list of indexes corresponding to matching items. Items which are stored within cache can then be used to hydrate the list and update the list shown on the catalog page.
