# storyteller-backend

## Authentication

This application uses Supabase for authentication, following a multi-Supabase architecture:

1. A central auth Supabase instance ("mana") handles user authentication
2. An application-specific Supabase instance ("maerchenzauber") handles application data
3. The NestJS backend serves as a token exchange middleware and application server

### Setup Requirements

You need to set up two Supabase instances:

1. **mana** - Central authentication service
2. **maerchenzauber** - Application-specific database

See `auth.md` for detailed setup instructions and database schema.

### Environment Variables

Configure the following environment variables (see `.env.example`):

- `MANA_SUPABASE_URL` - URL of the central auth Supabase instance
- `MANA_SUPABASE_ANON_KEY` - Anon key for the central auth Supabase
- `MANA_JWT_SECRET` - JWT secret for verifying tokens from the central auth
- `MAERCHENZAUBER_SUPABASE_URL` - URL of the application Supabase instance
- `MAERCHENZAUBER_SUPABASE_ANON_KEY` - Anon key for the application Supabase
- `MAERCHENZAUBER_JWT_SECRET` - JWT secret for signing tokens for the application Supabase
- `APP_ID` - Application identifier (default: "8d2f5ddb-e251-4b3b-8802-84022a7ac77f")
