Okay, so I recently decided to make a blog post that automatically updated. This turns out to be super, super easy to do with my current setup, which uses the Zola toolkit to generate a static website from templates and markdown files, as well as Netlify, which automatically redeploys my site whenever I push a change to the git repo.
My approach took me five minutes to write, and it definitely works. It is completely lightweight and nice on my end. It is not completely lightweight and nice on my webhost's end, and I would recommend using it extremely sparingly, if at all.
