    const result = await register("John Doe", "john@example.com");
    if (result.success) {
      console.log("Registration successful!");
      // User is now authenticated!
    }
  };

  const handleLogin = async () => {
    const result = await login("john@example.com");
    if (result.success) {
      console.log("Welcome back!", result.user);
      // User is logged in!
    }
  };

  return (
    <div>
      <button onClick={handleRegister}>Create Account with Passkey</button>
      <button onClick={handleLogin}>Sign In with Passkey</button>
    </div>
  );
}

🐕 Dog Fooding at Its Finest: Real-World Implementation

🔐 Credentials Vault - The Perfect Test Case

• High security requirements - storing sensitive credentials demands the best authentication

• Real user scenarios - actual developers using it daily

• Complex workflows - registration, login, credential management

• Production environment - real-world performance testing

🎯 Implementation Highlights

// Server-side configuration
const passkeyServer = createPasskeyServer({
  jwtSecret: process.env.JWT_SECRET!,
  database: new DatabaseAdapter(),
  rpName: "Credentials Vault",
  rpId: "credentials-vault.com",
  origin: "https://credentials-vault.com",
});

// Client-side authentication
const { register, login, isSupported } = usePasskeyAuth();

// Seamless user experience
if (!isSupported()) {
  return <div>Passkeys not supported on this device</div>;
}

📊 What I've Learned from Real Usage

🌟 The Technical Deep Dive

🏗️ Architecture Highlights

Client-Side (/client)

• React hooks for easy integration

• WebAuthn API abstraction

• Error handling with user-friendly messages

• Browser compatibility detection

Server-Side (/server)

• JWT token management with secure defaults

• Database adapter pattern for flexibility

• Challenge generation and verification

• Security validation and origin checking

Utilities (/utils)

• Crypto helpers for secure operations

• Type conversions for WebAuthn data

• Validation functions for data integrity

• UUID generation for unique identifiers

🔧 Database Adapter Pattern

interface DatabaseAdapter {
  // User operations
  createUser(name: string, email: string): Promise<User>;
  getUserById(id: string): Promise<User | null>;
  getUserByEmail(email: string): Promise<User | null>;

  // Passkey operations
  savePasskey(
    userId: string,
    credentialId: string,
    publicKey: Uint8Array,
    counter: number
  ): Promise<void>;
  getPasskeyByCredentialId(credentialId: string): Promise<Passkey | null>;
  updatePasskeyCounter(credentialId: string, counter: number): Promise<void>;

  // Challenge operations
  saveChallenge(challenge: string, userId?: string): Promise<void>;
  getChallenge(challenge: string): Promise<{ userId?: string } | null>;
  deleteChallenge(challenge: string): Promise<void>;
}
