How to reflect cart count at the cart icon as and when products are added or removed from the cart in WooCommerce

Although there is a hassle free option of using WooCommerce.com as your e-commerce store, you may prefer to host your own.

If you are familiar with WordPress and wish to host your e-commerce website, WooCommerce is also available as a WordPress plugin that augments WordPress with e-commerce website features.

Although more work needs to be done for self-hosted WordPress sites, we have the option of creating our own themes without having to pay additional charges on top of the web hosting fees.

Such documents are usually static in nature and are served as they are to the web browser without any processing from the server end.

Comparing setting up an instance of the Nginx server with adding code in our Flask application, the latter can be a more convenient way for us to realise our minimal viable product. This post documents the proof of concept that I did to serve static files with Python 3 and Flask.
