There have been many tools created before that have helped inspire its creation.

I have been avoiding the creation of a new framework for several years. First I tried to solve all the features covered by **FastAPI** using many different frameworks, plug-ins, and tools.

# Sicherheit

Es gibt viele Wege, Sicherheit, Authentifizierung und Autorisierung zu handhaben.

Und normalerweise ist es ein komplexes und „schwieriges“ Thema.

In vielen Frameworks und Systemen erfordert allein die Handhabung von Sicherheit und Authentifizierung viel Aufwand und Code (in vielen Fällen kann er 50 % oder mehr des gesamten geschriebenen Codes ausmachen).

# Security

There are many ways to handle security, authentication and authorization.

And it normally is a complex and "difficult" topic.

In many frameworks and systems just handling security and authentication takes a big amount of effort and code (in many cases it can be 50% or more of all the code written).

# Segurança

Há várias formas de lidar segurança, autenticação e autorização.

E isso normalmente é um tópico “difícil” e complexo.

Em muitos frameworks e sistemas, apenas lidar com segurança e autenticação exige muito esforço e código (em muitos casos isso pode ser 50% ou mais de todo o código escrito).

Essa "espera" é medida em microssegundos, e ainda assim, somando tudo, é um monte de espera no final.

Por isso que faz muito mais sentido utilizar código assíncrono para APIs web.

## Servidores ASGI

Vamos nos aprofundar um pouco mais em detalhes.

FastAPI utiliza um padrão para construir frameworks e servidores web em Python chamado <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>. FastAPI é um framework web ASGI.

That's why **FastAPI** is based on Starlette, as it is the fastest framework available (tested by third-party benchmarks).

Falcon is another high performance Python framework, it is designed to be minimal, and work as the foundation of other frameworks like Hug.

C'est pourquoi **FastAPI** est basé sur Starlette, car il s'agit du framework le plus rapide disponible (testé par des benchmarks tiers).

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *

* Schwer beeindruckende Performanz. Es ist <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">eines der schnellsten Python-Frameworks, auf Augenhöhe mit **NodeJS** und **Go**</a>.
* **WebSocket**-Unterstützung.
* Hintergrundaufgaben im selben Prozess.
* Ereignisse beim Starten und Herunterfahren.
* Testclient baut auf HTTPX auf.
