🛡️ Best Practices
- Environment Management: Use
venvorpoetryfor dependency isolation - Security: Store database credentials in environment variables
- Performance: Implement connection pooling in production
- Migrations: Track schema changes from day one
- Testing: Start with SQLite, deploy with PostgreSQL
- Async Operations: Pair FastAPI with
asyncpgfor maximum performance - Caching: Add Redis for session storage and caching
- Task Queues: Use Celery for background jobs
📚 Learning Path Recommendations
- Beginners: Flask + SQLite + SQLAlchemy
- Intermediate: Django + PostgreSQL + Django ORM
- Advanced: FastAPI + PostgreSQL + SQLModel + Redis + Celery
