Making a little Obsidian plugin that lets you cook small apps right inside of your vault. I find boilerplate annoying for little experiments, so I got rid of all of it. Each file is a standalone little app that automatically gets built and executed. Data persistence is also usually a pain, so it's nice to be able to just do it HyperCard style and have changes auto-save right to the file.

Does the data get persisted directly into the md text like Logseq?

Right into the source code file,

export const persistentData

gets updated with whatever you put in there frontmatter-style.
