You most probably don't need these technical details.

These details are useful mainly if you had a FastAPI application older than 0.121.0 and you are facing issues with dependencies with `yield`.

This is especially the case for user models, because:

Never store user's plaintext passwords. Always store a "secure hash" that you can then verify.

FastAPI uses a standard for building Python web frameworks and servers called <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>. FastAPI is an ASGI web framework.

The main thing you need to run a **FastAPI** application (or any other ASGI application) in a remote server machine is an ASGI server program like **Uvicorn**, this is the one that comes by default in the `fastapi` command.

Isso provavelmente não é tão importante ou necessário se você usar `Annotated`.

Vamos supor que você queira declarar o parâmetro de consulta `q` como uma `str` obrigatória.

But remember that when you import `Query`, `Path`, `Cookie` and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare cookies, you need to use `Cookie`, because otherwise the parameters would be interpreted as query parameters.
