### Mount the sub-application { #mount-the-sub-application }

In your top-level application, `app`, mount the sub-application, `subapi`.

In this case, it will be mounted at the path `/subapi`:

{* ../../docs_src/sub_applications/tutorial001.py hl[11, 19] *}

Hal ini berbeda dari menggunakan `APIRouter` karena aplikasi yang dimount benar-benar independen. OpenAPI dan dokumentasi dari aplikasi utama Anda tak akan menyertakan apa pun dari aplikasi yang dimount, dst.

Anda dapat mempelajari mengenai ini dalam [Panduan Pengguna Lanjutan](../advanced/index.md){.internal-link target=_blank}.

## Detail

# Including WSGI - Flask, Django, others { #including-wsgi-flask-django-others }

You can mount WSGI applications as you saw with [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank}, [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}.

For that, you can use the `WSGIMiddleware` and use it to wrap your WSGI application, for example, Flask, Django, etc.

## Using `WSGIMiddleware` { #using-wsgimiddleware }

        // Process multiple elements
        int count = 1;
        while (transaction.hasMoreElements() && count < 10) {
            transaction.nextElement();
            count++;
        }

        assertTrue(count > 1, "Large data should require multiple elements");
    }

    @Test

### Technische Details: `root_path`

Wenn Sie eine Unteranwendung wie oben beschrieben mounten, kümmert sich FastAPI darum, den Mount-Pfad für die Unteranwendung zu kommunizieren, mithilfe eines Mechanismus aus der ASGI-Spezifikation namens `root_path`.
