Here’s a link to it to try yourself :)
https://github.com/con-dog/serverless-architectureI should Have added more context. As you write in the notebook/notepad, it updates a visual link at the bottom of the note. The link says “Drag me to the bookmarks bar”. You can drag it and it re-saves the executable including its data and timestamps the bookmark.
From memory it rewrites itself because the link itself is self-hosting state and executable of the page itself. That’s the Quine part, so when you save that link you’re saving the entire notebook “engine” + the state. Was really fun to make in an evening
Nah it’s just a plain notebook/notepad, but I was also thinking of making something similar as a JavaScript scratch pad too that works in the same way, but would be an IDE + runnable snippets. Same concept, a Quine + bookmarklet that can sync between devices without a server
