User Sign-Up

This feature allows you to add a user sign-up component to your Next.js application. The SignUp component handles the entire sign-up process, including form validation and user creation.

import { SignUp } from '@clerk/nextjs';

export default function SignUpPage() {
  return <SignUp />;
}

User Sign-In

This feature allows you to add a user sign-in component to your Next.js application. The SignIn component manages the sign-in process, including form validation and authentication.

import { SignIn } from '@clerk/nextjs';

export default function SignInPage() {
  return <SignIn />;
}

User Profile Management

import { UserProfile } from '@clerk/nextjs';

export default function UserProfilePage() {
  return <UserProfile />;
}

Authentication State

This feature allows you to manage and display authentication states in your Next.js application. The useAuth hook provides information about the current authentication state and the authenticated user.

import { useAuth } from '@clerk/nextjs';

export default function AuthStateComponent() {
  const { isSignedIn, user } = useAuth();

  if (isSignedIn) {
    return <div>Welcome, {user.firstName}!</div>;
  } else {
    return <div>Please sign in.</div>;
  }
}

Protected Routes

This feature allows you to protect routes in your Next.js application. The withAuth higher-order component ensures that only authenticated users can access the protected page.

import { withAuth } from '@clerk/nextjs';

function ProtectedPage() {
  return <div>This is a protected page.</div>;
}

export default withAuth(ProtectedPage);
