## 🆕 New APIs

### Core APIs

```tsx
// New core session manager
import { createSessionManager, ReturnToManager } from 'sessionize-auth';

const sessionManager = createSessionManager({
  storageType: 'localStorage',
  returnToParam: 'returnTo'
});

// Return-to functionality
ReturnToManager.saveReturnTo('/dashboard/settings');
const returnTo = ReturnToManager.getReturnTo();
```

### React Adapter

```tsx
// New React integration
import { AuthProvider, useAuth, withAuth } from 'sessionize-auth';

// Provider with configuration
<AuthProvider config={{ storageType: 'localStorage' }}>
  <App />
</AuthProvider>

// Modern hook API
const { account, isAuthenticated, login, logout } = useAuth();

// Enhanced HOC
const ProtectedComponent = withAuth({
  redirectPath: '/login',
  fallback: LoadingComponent
})(MyComponent);
```

### SSO Integration

```tsx
// SSO configuration and usage
import { SSOManager, useSSO, SSOProviderList } from 'sessionize-auth';

// Configure SSO providers
const ssoManager = new SSOManager({
  providers: [
    {
      id: 'google',
      name: 'Google',
      clientId: 'your-google-client-id',
      redirectUri: 'http://localhost:3000/auth/callback',
      scopes: ['openid', 'email', 'profile']
    }
  ]
});

// Use SSO in components
function LoginPage() {
  const { login } = useAuth();
  const { providers, loginWithProvider } = useSSO(ssoManager);

  const handleSSOLogin = async (providerId: string) => {
    const result = await loginWithProvider(providerId);
    if (result.success && result.user) {
      login(result.user);
    }
  };

  return (
    <SSOProviderList 
      providers={providers}
      onProviderLogin={handleSSOLogin}
    />
  );
}
```

### Storage APIs

```tsx
// Pluggable storage backends
import { 
  createLocalStorageStore,
  createSessionStorageStore,
  createCookiesStore,
  createMemoryStore
} from 'sessionize-auth/stores';

const localStorage = createLocalStorageStore('my_app_session');
const memoryStore = createMemoryStore();
```

## 🔄 Migration Guide

### From v1.x to v2.0

#### ✅ **No Breaking Changes for Basic Usage**

Your existing code will continue to work:

```tsx
// This still works exactly the same
import { createSessionStore } from 'sessionize-auth';

const useSessionStore = createSessionStore({
  storageType: 'localStorage'
});

// HOC usage remains the same
import withAuth from 'sessionize-auth';
const ProtectedComponent = withAuth(MyComponent, useSessionStore, '/login');
```

#### 🆕 **Recommended Migration to New APIs**

**Old Way (v1.x):**
```tsx
import { createSessionStore } from 'sessionize-auth';
import withAuth from 'sessionize-auth';

const useSessionStore = createSessionStore({ storageType: 'localStorage' });
const ProtectedComponent = withAuth(MyComponent, useSessionStore, '/login');
```

**New Way (v2.0):**
```tsx
import { AuthProvider, useAuth, withAuth } from 'sessionize-auth';

// Wrap your app
<AuthProvider config={{ storageType: 'localStorage' }}>
  <App />
</AuthProvider>

// Use modern hook
const { account, isAuthenticated, login, logout } = useAuth();

// Or use enhanced HOC
const ProtectedComponent = withAuth()(MyComponent);
```
