## Other middlewares

There are many other ASGI middlewares.

For example:

<div class="screenshot">

</div>

/// info

Have in mind that, as **browsers handle cookies** in special ways and behind the scenes, they **don't** easily allow **JavaScript** to touch them.

If you go to the **API docs UI** at `/docs` you will be able to see the **documentation** for cookies for your *path operations*.

Dies ist lediglich eine **schnelle Anleitung / Auffrischung** über Pythons Typhinweise. Sie deckt nur das Minimum ab, das nötig ist, um diese mit **FastAPI** zu verwenden ... was tatsächlich sehr wenig ist.

**FastAPI** basiert vollständig auf diesen Typhinweisen, sie geben der Anwendung viele Vorteile und Möglichkeiten.

Aber selbst wenn Sie **FastAPI** nie verwenden, wird es für Sie nützlich sein, ein wenig darüber zu lernen.

        // Why? The second half of condition2 requires that nodeV equals other.nodeU.
        // We already know that nodeU equals other.nodeU. Combined with the earlier statement,
        // and the transitive property of equality, this implies that nodeU equals nodeV.
        // If nodeU equals nodeV, condition1 == condition2, so checking condition1 is sufficient.

Der `TestClient` basiert auf <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> und glücklicherweise können wir ihn direkt verwenden, um die API zu testen.
