TanStack Start server/client code boundary patterns. Use when: debugging virtual module resolution errors (tanstack-start-injected-head-scripts, tanstack-start-manifest, #tanstack-router-entry), importing from @tanstack/react-start/server, using getCookie/getRequestHeaders/getRequestUrl, adding providers to router.tsx, or when Vite fails to resolve TanStack Start imports. Covers createServerFn patterns, dynamic imports, and proper placement of server-only code.

TanStack Start Server/Client Boundaries

The Problem

TanStack Start uses Vite's environment API to register virtual modules (tanstack-start-injected-head-scripts:v, tanstack-start-manifest:v, etc.) only for the server environment. When you import server-only code at the top level of files that are also bundled for the client, Vite fails to resolve these virtual modules.

Error Signatures

Failed to resolve import "tanstack-start-injected-head-scripts:v"
Failed to resolve import "tanstack-start-manifest:v"
Could not resolve "#tanstack-router-entry"
Could not resolve "#tanstack-start-entry"

Root Cause

Top-level imports from @tanstack/react-start/server in files processed by both client AND server:

// __root.tsx, router.tsx, or any route file
import { getCookie } from "@tanstack/react-start/server"  // BREAKS CLIENT BUNDLE

Problematic Files

These files are bundled for BOTH client and server:

src/router.tsx
src/routes/__root.tsx
src/routes/**/*.tsx (all route files)
Any file imported by the above

Problematic Imports

Never import these at top level in client-bundled files:

// FROM @tanstack/react-start/server
import { getCookie, setCookie } from "@tanstack/react-start/server"
import { getRequestHeaders } from "@tanstack/react-start/server"
import { getRequestUrl } from "@tanstack/react-start/server"
import { getRequest } from "@tanstack/react-start/server"

// FROM @tanstack/react-start-server (internal package)
import { getCookie } from "@tanstack/react-start-server"

Solutions

Solution 1: Use createServerFn with Dynamic Import

Wrap server-only code in a server function using dynamic imports:

// server-fns/cookie-fns.ts
import { createServerFn } from "@tanstack/react-start"

export const getThemeCookieFn = createServerFn({ method: "GET" }).handler(
  async () => {
    const { getCookie } = await import("@tanstack/react-start/server")
    return getCookie("theme")
  },
)

Then use the server function instead:

// routes/__root.tsx
import { getThemeCookieFn } from "@/server-fns/cookie-fns"

beforeLoad: async () => {
  const theme = await getThemeCookieFn()  // Safe - calls server function
  return { theme }
}

Solution 2: Keep Server Imports in server-fns/ Files

Server function files (src/server-fns/*.ts) can use top-level imports from @tanstack/react-start/server IF they only export createServerFn functions:

// server-fns/auth-fns.ts - OK because only exports server functions
import { createServerFn } from "@tanstack/react-start"
import { getCookie } from "@tanstack/react-start/server"  // OK here

export const getSessionFn = createServerFn({ method: "GET" }).handler(
  async () => {
    const sessionId = getCookie("session")
    // ...
  },
)

Warning: If any non-server-function code imports from this file, the chain breaks.

Solution 3: Move Client Providers Out of router.tsx

The router.tsx file's InnerWrap runs during SSR. Client-only providers here cause issues:

// router.tsx - BAD
import { PostHogProvider } from "./lib/posthog/provider"  // Client-only!

export const getRouter = () => {
  const router = createRouter({
    routeTree,
    InnerWrap: ({ children }) => (
      <PostHogProvider>{children}</PostHogProvider>  // Breaks SSR
    ),
  })
  return router
}

Move providers to __root.tsx RootDocument:

// routes/__root.tsx - GOOD
import { PostHogProvider } from "@/lib/posthog/provider"

function RootDocument({ children }) {
  return (
    <html>
      <body>
        <PostHogProvider>
          {children}
        </PostHogProvider>
      </body>
    </html>
  )
}

File Organization Pattern

src/
├── router.tsx              # NO server imports, NO client-only providers
├── routes/
│   ├── __root.tsx          # NO direct server imports, use server-fns
│   └── *.tsx               # NO direct server imports, use server-fns
├── server-fns/             # Server functions with createServerFn
│   ├── auth-fns.ts         # Can import from @tanstack/react-start/server

└── lib/
    └── posthog/
        └── provider.tsx    # "use client" - add to __root.tsx body, not router.tsx

Quick Diagnostic

When you see virtual module errors:

Search for @tanstack/react-start/server imports outside server-fns/:

grep -r "@tanstack/react-start/server" src/ --include="*.tsx" | grep -v server-fns

Check router.tsx for client-only provider imports
Look for import chains that pull server code into client bundles
