What third-party libraries have you used to supplement FastAPI functionality in your projects?

To extend the functionality of FastAPI in projects, the following third-party libraries are often used:

• Pydantic — for data validation and serialization.
• SQLAlchemy or Tortoise ORM — for working with databases.
• Alembic — for database migrations.
• Uvicorn — an ASGI server for running the application.
• HTTPX — for asynchronous HTTP requests.
• FastAPI Users — for managing authentication and users.
• Celery — for background tasks.

For example, with Pydantic, you can define data models as follows:

from pydantic import BaseModel

class User(BaseModel):
    id: int
    name: str
    email: str
