User Authentication

function UserProfile() {
  const { user, error } = useUser();

  if (error) return <div>Error: {error.message}</div>;
  if (!user) return <div>Loading...</div>;

  return <div>Welcome, {user.email}</div>;
}

Session Management

The useSession hook allows you to access the current session information, making it easy to determine if a user is logged in or not.

import { useSession } from '@supabase/auth-helpers-react';

function SessionInfo() {
  const { session } = useSession();

  return session ? <div>Session active</div> : <div>No active session</div>;
}

Auth Provider

The Auth component wraps your application and provides the necessary context for authentication, allowing you to use the hooks provided by the package.

import { Auth } from '@supabase/auth-helpers-react';

function App() {
  return (
    <Auth supabaseClient={supabase}>
      <YourAppComponents />
    </Auth>
  );
