The authors of the blog post decided to teach people how to sell carrots online using Snipcart, a static site generator called Roots, and an API-based CMS called Contentful. They created a simple static e-commerce site that allows merchants to easily manage products with a web-based editor, giving them autonomy and reducing recurring developer input. The authors used Middleman, a static site generator, and the contentful_middleman gem to integrate Contentful into their workflow, allowing for a modular approach to development and enabling efficient management of digital experiences.
