After creating a new TanStack Start project, I get a 404 error when serving the built app — without making any code changes.
npm run build
npm run serve

Hi! I'm having the same issue as fmcoder

Environment:

  • OS: Windows 11
  • Node: v24.7.0
  • TanStack Start: 1.132.48
  • TanStack Router: 1.132.47
  • Vite: 7.1.9
  • React: 18.3.1
  • pnpm: 9.14.2

Additional Context:
Migrated from React Router to TanStack Start manually following the "Build from Scratch" guide:
https://tanstack.com/start/latest/docs/framework/react/build-from-scratch

  • Didn't use the official template to avoid overwriting existing files
  • Created routes manually in src/routes/
  • Set up __root.tsx following the documentation
  • Added server functions with createServerFn in src/server
  • Configured vite.config.ts as per the guide

Issue:

  • pnpm dev works perfectly ✅
  • pnpm build succeeds ✅
  • pnpm preview shows "Cannot GET /" ❌
  • node dist/server/server.js doesn't start (no output, port not listening) ❌

What i tried

  • Using @netlify/vite-plugin-tanstack-start → breaks dev mode
  • Using vinxi → errors with __dirname in ES modules
  • Using node dist/server/server.js → server doesn't listen on any port

Config:

  • Using file-based routing
  • Server functions with createServerFn
  • Tailwind 4 + DaisyUI

Is there a way to test the production build locally?

A lot of the docs pages including that one are showing a 404
