Help developers set up @neondatabase/auth in Next.js App Router applications (auth only, no database).
Use this skill when:
'use client' directive: Required for client components using hooks/ui/css OR /ui/tailwind, never bothrouter.refresh() to update Server Components| Purpose | Import From |
|---|---|
Unified Server (createNeonAuth) | @neondatabase/auth/next/server |
| Client Auth | @neondatabase/auth/next |
| UI Components | @neondatabase/auth/react/ui |
| View Paths (static params) | @neondatabase/auth/react/ui/server |
Note: Use createNeonAuth() from @neondatabase/auth/next/server to get a unified auth instance that provides:
.handler() - API route handler.middleware() - Route protection middleware.signIn, .signUp, .getSession, etc.)npm install @neondatabase/auth
.env.local)NEON_AUTH_BASE_URL=https://your-auth.neon.tech
NEON_AUTH_COOKIE_SECRET=your-secret-at-least-32-characters-long
Important: Generate a secure secret (32+ characters) for production:
openssl rand -base64 32
lib/auth/server.ts)Create a auth instance that provides handler, middleware, and server methods:
import { createNeonAuth } from '@neondatabase/auth/next/server';
export const auth = createNeonAuth({
baseUrl: process.env.NEON_AUTH_BASE_URL!,
cookies: {
secret: process.env.NEON_AUTH_COOKIE_SECRET!,
sessionDataTtl: 300, // Optional: session data cache TTL in seconds (default: 300 = 5 min)
domain: '.example.com', // Optional: for cross-subdomain cookies
},
});
app/api/auth/[...path]/route.ts)import { auth } from '@/lib/auth/server';
export const { GET, POST } = auth.handler();
middleware.ts)import { auth } from '@/lib/auth/server';
export default auth.middleware({
loginUrl: '/auth/sign-in',
});
export const config = {

};

import { createAuthClient } from '@neondatabase/auth/next';
export const authClient = createAuthClient();
app/providers.tsx)'use client';
import { NeonAuthUIProvider } from '@neondatabase/auth/react/ui';
import Link from 'next/link';
import { useRouter } from 'next/navigation';
import { authClient } from '@/lib/auth/client';
export function Providers({ children }: { children: React.ReactNode }) {
const router = useRouter();
return (
<NeonAuthUIProvider
authClient={authClient}

replace={router.replace}
onSessionChange={() => router.refresh()}
redirectTo="/dashboard"
Link={({href, children}) => <Link to={href}>{children}</Link>}

);
}

import '@neondatabase/auth/ui/css';
export default function RootLayout({ children }: { children: React.ReactNode }) {
return (

);
}

}
Without Tailwind (pre-built CSS bundle ~47KB):
// app/layout.tsx
import '@neondatabase/auth/ui/css';
With Tailwind CSS v4 (app/globals.css):
@import 'tailwindcss';
@import '@neondatabase/auth/ui/tailwind';
IMPORTANT: Never import both - causes duplicate styles.
The provider includes next-themes. Control via defaultTheme prop:
<NeonAuthUIProvider
defaultTheme="system" // 'light' | 'dark' | 'system'
// ...
>
Override CSS variables in globals.css:
:root {
--primary: hsl(221.2 83.2% 53.3%);
--primary-foreground: hsl(210 40% 98%);
--background: hsl(0 0% 100%);
--foreground: hsl(222.2 84% 4.9%);
--card: hsl(0 0% 100%);
--card-foreground: hsl(222.2 84% 4.9%);
--border: hsl(214.3 31.8% 91.4%);
--input: hsl(214.3 31.8% 91.4%);
--ring: hsl(221.2 83.2% 53.3%);
--radius: 0.5rem;
}
.dark {
--background: hsl(222.2 84% 4.9%);
--foreground: hsl(210 40% 98%);
/* ... dark mode overrides */

// NO 'use client' - this is a Server Component
import { auth } from '@/lib/auth/server';
// Server components using `auth` methods must be rendered dynamically
export const dynamic = 'force-dynamic'
export async function Profile() {
const { data: session } = await auth.getSession();
if (!session?.user) return <div>Not signed in</div>;
return (
<div>
<p>Hello, {session.user.name}</p>
<p>Email: {session.user.email}</p>
</div>
);
}
// app/api/user/route.ts
import { auth } from '@/lib/auth/server';
import { NextResponse } from 'next/server';
export async function GET() {
const { data: session } = await auth.getSession();
if (!session?.user) {
return NextResponse.json({ error: 'Unauthorized' }, { status: 401 });
}
return NextResponse.json({ user: session.user });
}
Server actions use the same auth instance from lib/auth/server.ts:
// app/actions/auth.ts
'use server';
import { auth } from '@/lib/auth/server';
import { redirect } from 'next/navigation';
export async function signIn(formData: FormData) {
const { error } = await auth.signIn.email({
email: formData.get('email') as string,
password: formData.get('password') as string,
});
if (error) {
return { error: error.message };
}
redirect('/dashboard');
}
export async function signUp(formData: FormData) {
const { error } = await auth.signUp.email({
email: formData.get('email') as string,
password: formData.get('password') as string,
name: formData.get('name') as string,
});
if (error) {
return { error: error.message };
}
redirect('/dashboard');
}
export async function signOut() {
await auth.signOut();
redirect('/');
}
The auth instance from createNeonAuth() provides all Better Auth server methods:
// Authentication
auth.signIn.email({ email, password })
auth.signUp.email({ email, password, name })
auth.signOut()
auth.getSession()
// User Management
auth.updateUser({ name, image })
// Organizations
auth.organization.create({ name, slug })
auth.organization.list()
// Admin (if enabled)
auth.admin.listUsers()
auth.admin.banUser({ userId })
'use client';
import { authClient } from '@/lib/auth/client';
export function Dashboard() {
const { data: session, isPending, error } = authClient.useSession();
if (isPending) return <div>Loading...</div>;
if (error) return <div>Error: {error.message}</div>;
if (!session) return <div>Not signed in</div>;
return <div>Hello, {session.user.name}</div>;
}

await authClient.signIn.social({

Enable RLS-based data access for unauthenticated users:
// lib/auth/client.ts
'use client';
import { createAuthClient } from '@neondatabase/auth/next';
export const authClient = createAuthClient({
allowAnonymous: true,
});
const token = await authClient.getJWTToken();
// Use in API calls
const response = await fetch('/api/data', {
headers: { Authorization: `Bearer ${token}` },
});
Automatic via BroadcastChannel. Sign out in one tab signs out all tabs.
The onSessionChange callback is crucial for Next.js:
<NeonAuthUIProvider
onSessionChange={() => router.refresh()} // Refreshes Server Components!
// ...
>
Without this, Server Components won't update after sign-in/sign-out.
'use server';
export async function signIn(formData: FormData) {
const { error } = await authServer.signIn.email({
email: formData.get('email') as string,
password: formData.get('password') as string,
});
if (error) {
// Return error to client
return { error: error.message };
}
redirect('/dashboard');
}
'use client';
const { error } = await authClient.signIn.email({ email, password });
if (error) {
toast.error(error.message);
}
| Error | Cause |
|---|---|
Invalid credentials | Wrong email/password |
User already exists | Email already registered |
Email not verified | Verification required |
Session not found | Expired or invalid session |
Make sure you have onSessionChange={() => router.refresh()} in your provider:
<NeonAuthUIProvider
onSessionChange={() => router.refresh()}
// ...
>
Grant permissions to the anonymous role in your database:
GRANT SELECT ON public.posts TO anonymous;
GRANT SELECT ON public.products TO anonymous;
And configure RLS policies:
CREATE POLICY "Anyone can read published posts"
ON public.posts FOR SELECT
USING (published = true);
Check your matcher configuration:
export const config = {
matcher: [
'/dashboard/:path*',
'/account/:path*',
// Add your protected routes here
],
};
Ensure your API route is set up correctly at app/api/auth/[...path]/route.ts:
import { auth } from '@/lib/auth/server';
export const { GET, POST } = auth.handler();
