#### Using `Union` or `Optional` { #using-union-or-optional }

If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view:

* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.

 * Projects with longer downstream dependency chains are prioritized to maximize
 * parallel execution efficiency.
 *
 * <p>The algorithm calculates a weight for each project as:
 * weight = 1 + max(downstream_project_weights)
 *
 * <p>Projects are then sorted by weight in descending order, ensuring that
 * projects with longer dependency chains are built first. When projects have
 * the same weight, they are ordered by project ID for deterministic results.

The following arguments are supported:

* `allowed_hosts` - A list of domain names that should be allowed as hostnames. Wildcard domains such as `*.example.com` are supported for matching subdomains. To allow any hostname either use `allowed_hosts=["*"]` or omit the middleware.

## Get the `username` and `password` { #get-the-username-and-password }

We are going to use **FastAPI** security utilities to get the `username` and `password`.

OAuth2 specifies that when using the "password flow" (that we are using) the client/user must send a `username` and `password` fields as form data.
