vite-bug-repro-ssr-pnpm

A reproduction of broken SSR with CommonJS dependencies and pnpm.

app (a workspace) depends on pkg-a (another workspace) which depends on locale (a CommonJS npm dependency).

SSR crashes with ReferenceError: module is not defined from locale.

Reproduction steps:

corepack enable
pnpm install
node app/server.mjs
open http://localhost:5173

It is also worth noting that this does not error if the npm CJS package is a direct dependency of app.
