## Self-hosting JavaScript and CSS for docs

Self-hosting the JavaScript and CSS could be useful if, for example, you need your app to keep working even while offline, without open Internet access, or in a local network.

Here you'll see how to serve those files yourself, in the same FastAPI app, and configure the docs to use them.

### Project file structure

Let's say your project file structure looks like this:

```
.
├── app

		return err
	}

	// Validate that matching clientID appears in the aud or azp claims.

	// REQUIRED. Audience(s) that this ID Token is intended for.
	// It MUST contain the OAuth 2.0 client_id of the Relying Party
	// as an audience value. It MAY also contain identifiers for
	// other audiences. In the general case, the aud value is an
	// array of case sensitive strings. In the common special case

### Verlängerung des Zertifikats

Irgendwann in der Zukunft würde jedes Zertifikat **ablaufen** (etwa 3 Monate nach dem Erwerb).

Und dann gäbe es ein anderes Programm (in manchen Fällen ist es ein anderes Programm, in manchen Fällen ist es derselbe TLS-Terminierungsproxy), das mit Let's Encrypt kommuniziert und das/die Zertifikat(e) erneuert.

## `fastapi run`

Executing `fastapi run` starts FastAPI in production mode by default.

By default, **auto-reload** is disabled. It also listens on the IP address `0.0.0.0`, which means all the available IP addresses, this way it will be publicly accessible to anyone that can communicate with the machine. This is how you would normally run it in production, for example, in a container.

    for key, value in update_dict.items():
        if (
            key in main_dict
            and isinstance(main_dict[key], dict)
            and isinstance(value, dict)
        ):
            deep_dict_update(main_dict[key], value)
        elif (
            key in main_dict
            and isinstance(main_dict[key], list)
