Example Code

async @router.post("/login/access-token")
def login_access_token(
    session: SessionDep, form_data: Annotated[OAuth2PasswordRequestForm, Depends()]
) -> Token:
    """
    OAuth2 compatible token login, get an access token for future requests
    """
    user = crud.authenticate(
        session=session, email=form_data.username, password=form_data.password
    )
    if not user:
        raise HTTPException(status_code=400, detail="Incorrect email or password")
    elif not user.is_active:
        raise HTTPException(status_code=400, detail="Inactive user")
    access_token_expires = timedelta(minutes=settings.ACCESS_TOKEN_EXPIRE_MINUTES)
    return Token(
        access_token=security.create_access_token(
            user.id, expires_delta=access_token_expires
        )
    )

### Description

In the code of this project, I noticed that a synchronous approach is used, and all the APIs are non-asynchronous. I believe using asynchronous programming might be better, as it could better leverage FastAPI’s advantages. Of course, if the difference is not significant, using a synchronous approach could still work fine. I'm just not sure how big the difference really is, but I would recommend using the asynchronous approach.
