A FastAPI egy modern, gyors (nagy teljesítményű), webes keretrendszer API-ok építéséhez Python -al, a Python szabványos típusjelöléseire építve.


Kulcs funkciók:

Anyway, in any of the cases above, FastAPI will still work asynchronously and be extremely fast.

But by following the steps above, it will be able to do some performance optimizations.

## Technical Details

Modern versions of Python have support for **"asynchronous code"** using something called **"coroutines"**, with **`async` and `await`** syntax.

Let's see that phrase by parts in the sections below:

* **Asynchronous Code**

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets client

### In production

In your production system, you probably have a frontend created with a modern framework like React, Vue.js or Angular.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.

## Beispiel Aktualisierung

Ändern Sie jetzt die Datei `main.py`, um den <abbr title="Body – Körper, Inhalt: Der eigentliche Inhalt einer Nachricht, nicht die Metadaten">Body</abbr> einer `PUT`-Anfrage zu empfangen.

In diesem Beispiel wird es ganz einfach sein. Nehmen wir jedoch an, dass wir, da sie mit anderen Projekten in der Organisation geteilt wird, sie nicht ändern und kein `prefix`, `dependencies`, `tags`, usw. direkt zum `APIRouter` hinzufügen können:

```Python hl_lines="3" title="app/internal/admin.py"
{!../../docs_src/bigger_applications/app/internal/admin.py!}
```
