Vite SSR error with Nitro v3 plugin when using `nodeLinker: hoisted` in pnpm config

[wovw]

Environment

• Nitro: nitro-nightly latest
• Node: 24.8.0
• pnpm: 10.18.0
• Vite: 7.1.9

Reproduction

I have a new tanstack start app with turborepo + pnpm, nitro v3 plugin in vite config, and nodeLinker: hoisted in pnpm-workspace.yaml

Describe the bug

When using pnpm with nodeLinker: hoisted, Vite SSR fails to resolve Node.js built-in imports (node:events) in node-mock-http when Nitro v3 Vite plugin is enabled. This seems to be caused by the hoisted layout changing how dependencies are resolved and externalized. The full error is pasted below.

Can you please share a runnable reproduction?

Reproduction here: https://github.com/wovw/start-pnpm-nitro

Created with pnpm create @tanstack/start@latest, added nitro-nightly and pnpm-workspace.yaml with nodeLinker: hoisted for the bug

I can successfully build your project: (you might need to clean up node_modules + pnpm-lock.yaml)

@schiller-manuel Using h3-v2 alias in @tanstack/start/core (https://github.com/TanStack/router/blob/dc320144a5c1b00e443e54aed29a502f57e362ff/packages/start-server-core/package.json#L71) can BTW lead to more issues like this, asthe hoisted version of "expected" h3 will be v1. Please consider using normal "h3" as alias name.
