# @mana/auth-mobile Package Summary

## What Has Been Created

I've created a complete npm package structure for a reusable Mana Core authentication system. The package is located at:

```
/Users/wuesteon/memoro_new/mana-2025/storyteller-project/@mana-auth-mobile/
```

## What's Configurable

### 1. **Theme Configuration** (ManaAuthTheme)
   - Colors (primary, secondary, buttons, inputs, etc.)
   - Fonts (regular, bold, header)
   - Spacing (xs, sm, md, lg, xl)
   - Border radius (sm, md, lg, xl)
   - Background image
   - Blur intensity

### 2. **Text/Wording Configuration** (ManaAuthText)
   - App branding (name, icon)
   - All button labels
   - All placeholder text
   - All validation messages
   - All error messages
   - Legal text
   - Cross-app promotion content

### 3. **Environment Configuration** (ManaAuthEnvironment)
   - Backend URL (required)
   - OAuth credentials (Google, Apple)
   - Feature flags (enable/disable auth methods)
   - Analytics settings
   - Storage keys
   - Dev mode settings

## How to Complete the Package

### Step 1: Copy Service Files

Copy these files from storyteller and adapt them to use configuration:

```typescript
// authService.ts - Replace hardcoded values with config
const BACKEND_URL = config.environment.backendUrl;
const STORAGE_KEYS = config.environment.storageKeys;

// tokenManager.ts - No changes needed
```

### Step 2: Copy Component Files

Copy and adapt UI components to use theme/text config:

```typescript
// ManaLoginScreen.tsx
const { theme, text } = useManaAuthConfig();

// Use config values
<Text style={{ color: theme.colors.text }}>
  {text.loginTitle}
</Text>
```

### Step 3: Copy Context File

Copy AuthContext and make optional integrations:

```typescript
// ManaAuthContext.tsx
- Remove hardcoded Supabase (or make optional)
- Remove hardcoded RevenueCat (or make optional)
- Use config for analytics
```

### Step 4: Build and Test

```bash
cd @mana-auth-mobile
npm install
npm run build

# Test locally
npm link

# In storyteller
npm link @mana/auth-mobile
```

## Usage Example (Storyteller)

### Install
```bash
cd mobile
npm install ../../../@mana-auth-mobile
```

### Configure (app/_layout.tsx)
```typescript
import { ManaAuthConfigProvider, ManaAuthProvider } from '@mana/auth-mobile';

<ManaAuthConfigProvider
  environment={{
    backendUrl: process.env.EXPO_PUBLIC_STORYTELLER_BACKEND_URL,
    googleClientId: process.env.EXPO_PUBLIC_GOOGLE_CLIENT_ID,
  }}
  theme={{
    colors: { primary: '#FFCB00' },
    fonts: { header: 'Grandstander_700Bold' },
    backgroundImage: require('../assets/images/marchenzauber-dadgirl.jpg'),
  }}
  text={{
    appName: 'Märchenzauber',
    loginTitle: 'Märchenzauber',
    loginWithGoogle: 'Mit Google anmelden',
  }}
>
  <ManaAuthProvider>
    {children}
  </ManaAuthProvider>
</ManaAuthConfigProvider>
```

### Use (app/login.tsx)
```typescript
import { ManaLoginScreen } from '@mana/auth-mobile';

export default function LoginScreen() {
  return <ManaLoginScreen />;
}
```

### Use (any protected screen)
```typescript
import { useManaAuth } from '@mana/auth-mobile';

function MyScreen() {
  const { user, signOut } = useManaAuth();
  return <Text>Welcome {user?.name}!</Text>;
}
```

## Benefits

1. **Single Source of Truth**: One authentication codebase for all Mana apps
2. **Consistent UX**: Same flow across apps with app-specific branding
3. **Easy Maintenance**: Update once, deploy to all apps
4. **Type Safety**: Full TypeScript support with IntelliSense
5. **Flexibility**: Configure everything or use sensible defaults
6. **No Vendor Lock-in**: Can adapt middleware URLs per app
7. **Internationalization**: Easy to support multiple languages

## Next Steps

1. **Copy remaining files** from storyteller to complete the package
2. **Adapt services** to use configuration system
3. **Adapt components** to use theme/text configuration
4. **Test locally** with `npm link`
5. **Update storyteller** to use the package (validate it works)
6. **Publish to npm** (or private registry)
7. **Update other Mana apps** (Memoro) to use the package

## Files Created vs. Files to Copy

### ✅ Created (Infrastructure)
- Package configuration (package.json, tsconfig.json)
- Type definitions (types/index.ts, config/types.ts)
- Configuration system (defaults.ts, ManaAuthConfigProvider.tsx)
- Utilities (safeStorage, logger, deviceManager, networkErrorUtils)
- Documentation (README.md, IMPLEMENTATION_GUIDE.md)

### ⏳ To Copy (Business Logic)
- authService.ts (from mobile/src/services/)
- tokenManager.ts (from mobile/src/services/)
- ManaLoginScreen.tsx (from mobile/app/login.tsx)
- GoogleSignInButton.tsx (from mobile/components/molecules/)
- AppleSignInButton.tsx (from mobile/components/molecules/)
- ManaAuthContext.tsx (from mobile/src/contexts/AuthContext.tsx)

## Important Notes

- **No changes to storyteller code**: The current storyteller codebase is not modified
- **Side-by-side migration**: You can migrate screen-by-screen
- **Backward compatible**: Old auth code continues to work during migration
- **Configuration validation**: TypeScript ensures correct configuration
- **Dev mode support**: Triple-tap auto-login can be configured
