Vite creating its own node_modules in workspace instead of using monorepo

Question

I have a monorepo for a fullstack webapp with the following directory structure

.
├── client
│   ├── index.html
│   ├── package.json
│   ├── src
│   └── vite.config.ts
├── node_modules
├── package-lock.json
├── package.json
├── server
│   ├── package.json
│   └── src
├── tsconfig.json
└── tsconfig.node.json

However, when I run npm run dev -ws client, vite generates it's own node_modules/ inside client/.

.
├── client
│   ├── index.html
│   ├── node_modules <--- this
│   │   └── .vite
│   │       └── deps_temp
│   │           └── package.json
│   ├── package.json
│   ├── src
│   └── vite.config.ts

My understanding is that the point of using npm workspaces is to avoid having multiple node_modules/ in each sub-project, instead having all dependencies installed in the root node_modules/. Vite generating its own seems to defeat that point.

I'm assuming I don't have something configured properly (I used npx create-vite to setup vite).

(!) Could not auto-determine entry point from rollupOptions or html files and there are no explicit optimizeDeps.include patterns. Skipping dependency pre-bundling.

You did nothing wrong. node_modules/.vite is the default vite cache directory. It only looks like a misconfiguration in a monorepo because you don't expect a node_modules folder inside the packages anymore.

If you want, you can configure a different path: https://v2.vitejs.dev/config/#cachedir
