This is a small shop written for educational purposes in Flask with some js filled with randomly generated filler items.
To run it use pip install -r requirements.txt and then do flask run.
After that - navigate to localhost:5000 in your browser.
It uses in-memory sqlite db, so if you restart a server all carts will be removed from it, but cart_it still be kept in browser localstorage, which can lead to 404 if you click Cart icon right after restarting a server. To reset a cart_id just add some item to cart (or configure db to use a file).
Checkout button does nothing but delete all items from cart. There's currently no way to delete a single item from cart.
