E-Commerce Web App Using Python Flask and SQLAlchemy.

After completing my first computer science class through CS50 (EDX), I decided to build an e-commerce website using Python, Flask, SQLalchemy (and also HTML, CSS, Jinja).

The original website is hosted here and was built on Shopify. This is a zero waste business offering refilling services for cleaning and beauty products.

I reproduced this web app and tried to imitate their design and main features.

On this project I focused on implementing a shopping cart.

Once logged in, users can:

• Add products to their shopping cart
• Update the quantity, or Remove items
• See the total cost

The database includes 3 models: User, Products and Cart. When a user add a product to his cart, a new "cart item" will be added to the Cart model with the user id and product id.

How to run this application locally

To install all the packages, run:

pip3 install -r requirements.txt

Then run:

cd unwrap
python run.py
