I have successfully made feeds that are automatically generated/updated when I make a new blog post (JSON feed and RSS feed). The way this feed generation currently works is that every time that I push a new post (or when the blog posts csv file is changed) to the GitHub repo, a GitHub Action runs, which reads the blog posts csv file and then parses and converts the information it contains into feeds using a very cool Golang package that I found. I will hopefully soon add some features such as links and images to make posts easier on the eyes.
