Configuration Options

Mode Selection

Basic Mode

Minimal structure for small APIs or learning FastAPI.

Generated files:

• main.py - Application entry point
• routers/health.py - Health check endpoint
• schemas/base.py - Base Pydantic schema
• core/config.py - Configuration settings
• requirements.txt - Dependencies

Full Mode

Production-ready structure with all components.

Additional files in full mode:

• models/user.py - SQLAlchemy user model
• schemas/user.py - User Pydantic schemas
• crud/user.py - Database operations
• routers/users.py - User endpoints
• db/session.py - Database connection
• deps.py - Dependency injection
• tests/test_main.py - Test placeholder

Database Options

None

No database configuration. Suitable for simple APIs that don't need persistence.

SQLite

Embedded database, good for development and small applications.

• File-based, no server required
• Zero configuration
• Single-user only

PostgreSQL

Production-grade relational database.

• Concurrent connections
• Advanced features (JSON, arrays, etc.)
• Industry standard for web applications

MySQL

Popular open-source database.

• Widely supported
• Good performance
• Common in shared hosting environments

Authentication

None

No authentication system. All endpoints are public.

JWT

JSON Web Token authentication using OAuth2.

Features included:

• Password hashing with bcrypt
• Token creation and verification
• OAuth2 password flow
• Protected route dependency

To use authentication in your routes:

from fastapi import Depends, APIRouter
from deps import get_current_user

router = APIRouter()

@router.get("/protected")
def protected_route(user = Depends(get_current_user)):
    return {"message": f"Hello {user}"}

Docker Support

When enabled, generates:

Dockerfile

• Python 3.11 slim base image
• Installs dependencies
• Runs uvicorn

docker-compose.yml

• App service configuration
• PostgreSQL database service (if selected)
• Volume persistence
• Environment variable support

To use Docker:

docker-compose up --build

Your API will be available at http://localhost:8000
