On: Show HN: Turn Markdown into React/Svelte/Vue UI at runtime, zero build step

[etler]

I've been working on a similar project using MDX as the parser to enable runtime static JSX tags in markdown: https://www.timetler.com/2025/08/19/unlocking-rich-ui-compon...

I'm curious why you decided to go with a DSL instead of embedding an established language?

MDX is not secure by default, you'd be executing arbitrary JS code potentially sent by untrustworthy sources, which is advised against in the MDX website.

On the other hand, this is true of every web site using a JS-world framework, and worse, even static sites if they use JS ad scripts.
