If you do end up using this for any commercial purpose, or found the code useful please consider buying me a coffee:
A website built with 11ty that pulls posts from a Dev.to RSS feed and generates a static site with links to the posts. Live Demo
Check out the associated blog post on Dev.to here!

Source folder : _source
Output folder : _build
To build:
npm install
npx @11ty/eleventyTo modify the feed that the script calls, either set the environment variable DEVTO_APIURL or change the fallback URL in the _data/devtoapi.js file in the _source folder.
First, build the files, then upload the _build directory your favourite static site host!
