`import.meta.glob` (and dynamic MDX imports) not transformed in RSC build

[keufcp]

Environment

• vinext: 0.0.32
• vite: 8.0.1
• @vitejs/plugin-rsc: 0.5.21
• @cloudflare/vite-plugin: latest
• React: 19.2.x

Problem

In an App Router project with dynamic routes (e.g. [year]/[month]/[day]/[slug]/page.tsx),
MDX files cannot be loaded dynamically in the RSC build environment.

Attempt 1: Dynamic import with template literal

await import(`@/content/posts/${year}/${month}/${day}/${slug}/index.mdx`)

Error at runtime:

No such module "@/content/posts/..."

Attempt 2: import.meta.glob

// src/lib/mdx-loader.ts
export const mdxModules = import.meta.glob('@/content/posts/**/*.mdx', { eager: true })

Error at runtime:

TypeError: (intermediate value).glob is not a function

import.meta.glob is not being transformed by the RSC build pipeline (rolldown),
and reaches the Workers runtime as-is, causing a runtime error.

Expected behavior

import.meta.glob should be statically transformed at build time in the RSC environment,
as it is in standard Vite builds.

Workaround

None found. The nextra-docs-template example uses static imports only,
which is not viable for blog-style dynamic routing.

Notes

• @mdx-js/rollup is configured correctly (auto-detected by vinext)
• Static MDX imports (as in nextra-docs-template) work fine
• The issue is specific to the RSC build environment; the transformation
  that Vite normally applies to import.meta.glob does not occur there
