I think you can remove this check and simply attempt to retrieve markdown, and if there's nothing, then there's nothing :)

If we remove this check, the dynamic markdown pages will also be processed as if they were static. As a result, for dynamic markdown pages, anything other than the default path (download/archive) would render as an empty page

You misunderstood what I meant. Im saying we should delete all of this: https://github.com/nodejs/nodejs.org/pull/7794/files/37ad6e48ec57414ab15a7c73ee93e3b3586fd120#diff-10a9016cab7cf37c3006f242718c3c7e6201f213647b03440718bfd34fdc5d30R99-R124

And change the https://github.com/nodejs/nodejs.org/pull/7794/files/37ad6e48ec57414ab15a7c73ee93e3b3586fd120#diff-10a9016cab7cf37c3006f242718c3c7e6201f213647b03440718bfd34fdc5d30R129-R132 to instead of trying and failing to simply handle the file not existing gracefully. So if there's no content, then there's no content.

Now we're fetching this request twice, I wonder if the browser will dedupe the request?

Two separate requests are being made. In fact, we’re already retrieving this information for the release data generator, so instead of making another request, it would be better to use the release data provider while generating the versions for now?

We already use top-level awaits for the providers, so maybe the reqauest to await nodevu() could be done in a separate file, also as a top-level await?

Or at the very least as a Promise? Like:

export default nodevu({ fetch });

Import it and await it on generateAllVersionsData and the other generator?

Can we avoid the casting here? I assume os will be marked as "string"?

os is marked as ; "AIX" | "MAC" | "LINUX" | "OTHER" | "WIN" | "LOADING" 🥹

Yeah, I just don't think you need to assign a new constant, you can do the casting directly on usage no? Or just allow the sibling function to receive a string IDK, since there's a switch statement anyways.
