Summary: Reference for the @neondatabase/auth-ui package, which provides prebuilt React components for sign-in, sign-up, user menus, and protected routes. Components include NeonAuthUIProvider, AuthView, UserButton, and SignedIn, built on Better Auth UI. Use this page for the full NeonAuthUIProvider prop table, CSS import instructions for Tailwind v4 and non-Tailwind projects, or the neon-auth-codemod migration command.

Quick reference for Managed Better Auth UI components

Quick reference for Managed Better Auth UI components from @neondatabase/auth-ui. These components are built with Better Auth UI and work with Managed Better Auth.

Note: Migrating from older imports

Older releases re-exported the UI from @neondatabase/auth/react/ui and @neondatabase/neon-js/auth/react/ui. Those entrypoints are deprecated and will be removed in the next major version. Install @neondatabase/auth-ui directly and run the codemod to update existing imports:

npx -p @neondatabase/auth neon-auth-codemod --write <path>

npm install @neondatabase/neon-js@latest @neondatabase/auth-ui

Wrap your app with NeonAuthUIProvider to enable the UI components. The provider accepts configuration props that control which features are available.

import { NeonAuthUIProvider } from '@neondatabase/auth-ui';
import '@neondatabase/auth-ui/css';
import { authClient } from './auth';

function App() {
  return (
    <NeonAuthUIProvider authClient={authClient}>{/* Your app components */}</NeonAuthUIProvider>
  );
}

To enable Google sign-in (or other OAuth providers), add the social prop to the provider:

import { NeonAuthUIProvider } from '@neondatabase/auth-ui';
import { authClient } from './auth';

function App() {
  return (
    <NeonAuthUIProvider
      authClient={authClient}
      social={{
        providers: ['google', 'github', 'vercel'], // Enable Google, GitHub, and Vercel sign-in
      }}
    >
      {/* Your app */}
    </NeonAuthUIProvider>
  );
}

Note: Google OAuth works with shared credentials for development. GitHub OAuth requires custom credentials. The social.providers prop controls which provider buttons are displayed in the UI. For production, configure OAuth credentials in the Neon Console (branch → Auth) and register provider redirect URIs (see OAuth setup).

If using React Router, pass the navigate function and a custom Link component:

import { NeonAuthUIProvider } from '@neondatabase/auth-ui';
import { useNavigate, Link as RouterLink } from 'react-router-dom';
import { authClient } from './auth';

function App() {
  const navigate = useNavigate();

  return (
    <NeonAuthUIProvider
      authClient={authClient}
      navigate={navigate}
      Link={RouterLink}
      social={{
        providers: ['google', 'github', 'vercel'],
      }}
    >
      {/* Your app */}
    </NeonAuthUIProvider>
  );
}

Custom localization:

<NeonAuthUIProvider
  authClient={authClient}
  localization={{
    SIGN_IN: 'Welcome Back',
    SIGN_UP: 'Create Account',
    FORGOT_PASSWORD: 'Forgot Password?',
  }}
>

Custom sign-up fields:

<NeonAuthUIProvider
  authClient={authClient}
  additionalFields={{
    company: {
      label: 'Company',
      placeholder: 'Your company name',
      type: 'string',
      required: false,
    },
  }}
  signUp={{
    fields: ['name', 'company'],
  }}
>

For complete prop documentation, see the TypeScript types exported from @neondatabase/neon-js/auth/react.

<AuthView> accepts both path and pathname. Use path for a bare view name (for example, "sign-in"). Use pathname for a full URL path (for example, "/auth/sign-in"); the component extracts the last segment automatically.

Form Components: <SignUpForm>, <SignInForm>, <ForgotPasswordForm>, <ResetPasswordForm>, and <AuthCallback> are also available. <AuthView> includes sign-in and sign-up functionality with a "create account" link to switch between forms. Use the form components separately if you need more control over layout.

OAuth Provider Buttons: OAuth provider buttons (Google, GitHub, Vercel, etc.) appear automatically in <AuthView> when configured via the social.providers prop. OAuth buttons do not appear in standalone <SignInForm> or <SignUpForm> components.

Choose the import method based on your project setup:

If your project doesn't use Tailwind CSS, import the pre-built CSS bundle:

// In your root layout or app entry point
import '@neondatabase/auth-ui/css';

This includes all necessary styles (~47KB minified) with no additional configuration required.

If your project already uses Tailwind CSS v4, import the Tailwind-ready CSS to avoid duplicate styles:

/* In your main CSS file (for example, globals.css) */
@import 'tailwindcss';
@import '@neondatabase/auth-ui/tailwind';

This imports only the theme variables. Your Tailwind build generates the utility classes.

Warning: Never import both paths. This causes duplicate styles.

For customization options, see Styling details within each Better Auth UI component docs page. Example: Auth View styling.

import { AuthView } from '@neondatabase/auth-ui';
import '@neondatabase/auth-ui/css';

function App() {
  return <AuthView pathname="sign-in" />;
}

For Next.js App Router, use a catch-all route to handle all auth views. Create app/auth/[path]/page.tsx:

import { AuthView } from '@neondatabase/auth-ui';
import { authViewPaths } from '@neondatabase/auth-ui/server';

export const dynamicParams = false;

export function generateStaticParams() {
  return Object.values(authViewPaths).map((path) => ({ path }));
}

export default async function AuthPage({
  params,
}: {
  params: Promise<{ path: string }>;
}) {
  const { path } = await params;

  return (
    <main className="flex min-h-screen items-center justify-center p-4">
      <AuthView path={path} />
    </main>
  );
}

import { UserButton } from '@neondatabase/auth-ui';
import { authClient } from './auth';

function Header() {
  return (
    <header>
      <UserButton authClient={authClient} />
    </header>
  );
}

import { SignedIn, SignedOut, RedirectToSignIn } from '@neondatabase/auth-ui';

function Dashboard() {
  return (
    <>
      <SignedIn>
        <h1>Dashboard</h1>
      </SignedIn>
      <SignedOut>
        <RedirectToSignIn />
      </SignedOut>
    </>
  );
}
