The HTMLifier "converts" Scratch 3.0 projects to an HTML file by putting all the project data and the entire Scratch engine into one enormous file
The HTMLifier is a tool designed to convert Scratch 3.0 projects into HTML files. By packaging all project data and the Scratch engine into a single file, it provides a way to run Scratch projects outside of the Scratch platform. This conversion process involves fetching project assets, converting them into base64 data URIs, and integrating them into a template HTML file.
HTML templates are pre-designed and pre-built web pages that can be customized and used as a basis for building websites. They often include common elements such as headers, footers, menus, and content sections, and can be easily edited using HTML and CSS to fit specific branding and content needs.
