# FastAPI Topluluğu

FastAPI, her kökenden insanı ağırlayan harika bir topluluğa sahip.

## Yazan - Geliştiren

Merhaba! 👋

İşte bu benim:

{% if people %}
<div class="user-list user-list-center">
{% for user in people.maintainers %}

Die Hierarchie ist wie folgt:

* **Uvicorn**: ein ASGI-Server
    * **Starlette**: (verwendet Uvicorn) ein Web-Mikroframework
        * **FastAPI**: (verwendet Starlette) ein API-Mikroframework mit mehreren zusätzlichen Funktionen zum Erstellen von APIs, mit Datenvalidierung, usw.

* **Uvicorn**:
    * Bietet die beste Leistung, da außer dem Server selbst nicht viel zusätzlicher Code vorhanden ist.

The hierarchy is like:

* **Uvicorn**: an ASGI server
    * **Starlette**: (uses Uvicorn) a web microframework
        * **FastAPI**: (uses Starlette) an API microframework with several additional features for building APIs, with data validation, etc.

* **Uvicorn**:
    * Will have the best performance, as it doesn't have much extra code apart from the server itself.

    * No entanto, existe uma solução para isso.
* Há uma extensão para o protocolo TLS (aquele que lida com a criptografia no nível TCP, antes do HTTP) chamado <a href="https://en.wikipedia.org/wiki/Server_Name_Indication" class="external-link" target="_blank"><abbr title="Server Name Indication">SNI</abbr></a>.
    * Esta extensão SNI permite que um único servidor (com um único endereço IP) tenha vários certificados HTTPS e atenda a vários domínios / aplicativos HTTPS.

In this section we'll see how to use other middlewares.

## Adding ASGI middlewares

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.
