Compiling MDsveX file with the content "import.meta.env" in SvelteKit fails the build

[danawoodman]

I've come across a strange bug with MDsveX (0.10.5) and SvelteKit (1.0.0-next.249).

If you create a MDsveX file with the string import.meta.env, then the command npm run build fails with:

[rollup-plugin-dynamic-import-variables] Unexpected token (37:15)
file: /Users/danawoodman/code/danawoodman.com/src/routes/using-environment-variables-in-sveltekit-and-vite.svx:37:15

import.meta.env is a global in Vite that you can use to grab out environment variables and I happened to write a blog post on that subject but if the content mentions import.meta.env anywhere the build fails. If I remove it, it works fine.

For example, try to compile this file with the latest version of SvelteKit and MDsveX (use npm init svelte@next then npx svelte-add mdsvex):

---
title: Foo
---

Let's talk about `import.meta.env` in Vite!

Then try to build with npm run build.

I'm reporting here but let me know if this makes more sense in one of the other repos instead.

Looks like this is a Vite issue: vitejs/vite#3304

You're totally right. Closing
