 To add more to that, I found [mdsvex](https://mdsvex.pngwn.io/), which allows one to use markdown from svelte, and use svelte from markdown.  
 Their website only specifies how to use it on classic Svelte (via rollup or webpack), but Svelte Kit hides this configuration (in addition to using vite in dev mode).

 This meant that the page was only client side, and the server only pre-compiled JS and sent only minimal HTML markup (which mostly just linked JS which did everything else). This meant the page didn't work without JS and took a bit to load.
 
-To fix that, I later moved it into Svelte Kit page (Svelte does support SSR, but it's easier to use Svelte Kit) and used the `static` adapter which meant that all the pages are now prerendered and work without JS.

 If you use the `adapter-auto`, deploying to Cloudflare pages should work nearly as is, you just need to set `NODE_VERSION` environment variable to `14` or `16`, as it's by default set to `12` which is too old for Svelte kit to work.
