This skill covers configuring TanStack Start to run in client-only mode by disabling server-side rendering (SSR). This is useful when you want SPA-like behavior or when your application doesn't benefit from SSR.
Use client-only mode when:
Modify your src/router.tsx to disable SSR:
import { createRouter } from '@tanstack/react-router'
import { routeTree } from './routeTree.gen'
export const router = createRouter({
routeTree,
defaultSsr: false, // Disable server-side rendering globally
})
declare module '@tanstack/react-router' {
interface Register {
router: typeof router
}
}
You can also control SSR on a per-route basis by setting ssr: false in individual route definitions:
// src/routes/dashboard.tsx
import { createFileRoute } from '@tanstack/react-router'
export const Route = createFileRoute('/dashboard')({
// Disable SSR for this specific route
ssr: false,
component: DashboardComponent,
})
function DashboardComponent() {
return <div>Dashboard (Client-Only)</div>
}
Ensure your src/routes/__root.tsx is properly configured for client-only rendering:
import { createRootRoute, Outlet } from '@tanstack/react-router'
export const Route = createRootRoute({
component: () => (
<html>
<head>
<meta charSet="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>TanStack Start App (Client-Only)</title>
</head>
<body>
<div id="root">
<Outlet />
</div>
</body>
</html>
),
})
In client-only mode, you can safely use browser APIs without checking for SSR:
import { createFileRoute } from '@tanstack/react-router'
import { useEffect, useState } from 'react'
export const Route = createFileRoute('/example')({
component: ExampleComponent,
})
function ExampleComponent() {
const [data, setData] = useState(null)
useEffect(() => {
// Browser APIs work directly since there's no SSR
const stored = localStorage.getItem('data')
if (stored) {
setData(JSON.parse(stored))
}
// Window object is available
console.log('Window size:', window.innerWidth, window.innerHeight)
}, [])
return <div>Example Component</div>
}
For pure client-only builds, you can simplify your vite.config.ts:
import { defineConfig } from 'vite'
import { tanstackStart } from '@tanstack/react-start/plugin/vite'
import viteReact from '@vitejs/plugin-react'
import tsconfigPaths from 'vite-tsconfig-paths'
export default defineConfig({
server: {
port: 3000,
},
plugins: [
tsconfigPaths(),
tanstackStart({
// Client-only mode configuration
ssr: false, // Disable SSR at build level
}),
viteReact(),
],
})
Create .env for client-side environment variables:
# .env
VITE_API_BASE_URL=http://localhost:8000/api/v1
VITE_APP_NAME=My TanStack App
Access them in your components:
const apiBaseUrl = import.meta.env.VITE_API_BASE_URL
const appName = import.meta.env.VITE_APP_NAME
Note: In client-only mode, all VITE_* variables are exposed to the client bundle. Never store secrets here.
Build your client-only application:
bun run build
This creates a static bundle in .output/ that can be deployed to:
| Feature | SSR (default) | Client-Only (defaultSsr=false) |
|---|---|---|
| Initial page load | Fully rendered HTML | Empty HTML shell |
| SEO | Excellent | Limited (depends on crawlers) |
| Time to First Byte (TTFB) | Slower (server processing) | Fast (static HTML) |
| JavaScript bundle | Hydration required | Direct execution |
| Server-side APIs | Available via server functions | Must use external API |
| Browser APIs | Require checks | Always available |
| Deployment | Node.js server required | Static hosting works |
Use client-only for authenticated apps: Dashboards, admin panels, and internal tools benefit from simpler client-only architecture.
Combine both modes: Use SSR for marketing pages (/, /pricing, /blog) and client-only for app routes (/dashboard/*, /settings/*):
// src/routes/__root.tsx
export const Route = createRootRoute({
component: RootComponent,
})
// src/routes/index.tsx (SSR - default)
export const Route = createFileRoute('/')({
component: HomePage,
})
// src/routes/dashboard.tsx (Client-only)
export const Route = createFileRoute('/dashboard')({
ssr: false, // Disable SSR for dashboard
component: Dashboard,
})
import { lazy } from 'react'
const HeavyComponent = lazy(() => import('./HeavyComponent'))
function Dashboard() {
return (
<div>
<Suspense fallback={<div>Loading...</div>}>
<HeavyComponent />
</Suspense>
</div>
)
}
// src/routes/__root.tsx
export const Route = createRootRoute({
component: () => (
<html>
<head>
<meta charSet="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>TanStack Start App</title>
<style>{`
.app-loading {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
font-family: system-ui;
}
`}</style>
</head>
<body>
<div id="root">
<div className="app-loading">Loading application...</div>
<Outlet />
</div>
</body>
</html>
),
})
After configuring client-only mode:
bun run dev
Cause: Accidentally running SSR code when defaultSsr: false isn't set.
Solution: Ensure defaultSsr: false in router configuration:
export const router = createRouter({
routeTree,
defaultSsr: false,
})
Cause: JavaScript bundle failed to load or execute.
Solution: Check browser console for errors and verify bundle path in network tab.
Cause: Mixing SSR and client-only rendering.
Solution: Be consistent - either use defaultSsr: false globally or manage per-route carefully.
