FastAPI é um moderno e rápido (alta performance) _framework web_ para construção de APIs com Python, baseado nos _type hints_ padrões do Python.

Os recursos chave são:

* **Rápido**: alta performance, equivalente a **NodeJS** e **Go** (graças ao Starlette e Pydantic). [Um dos frameworks mais rápidos disponíveis](#performance).

E esse é o mesmo nível de performance que você tem com o **FastAPI**.

 * Futures#transform(ListenableFuture, Function, Executor) Futures.transform}, but you will often
 * find it easier to use a framework. Frameworks automate the process, often adding features like
 * monitoring, debugging, and cancellation. Examples of frameworks include:
 *
 * <ul>
 *   <li><a href="https://dagger.dev/producers.html">Dagger Producers</a>
 * </ul>
 *

And that's the same level of performance you get with **FastAPI**.

And as you can have parallelism and asynchronicity at the same time, you get higher performance than most of the tested NodeJS frameworks and on par with Go, which is a compiled language closer to C <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(all thanks to Starlette)</a>.

Y ese es el mismo nivel de rendimiento que obtienes con **FastAPI**.

Et c'est le même niveau de performance que celui obtenu avec **FastAPI**.

Et comme on peut avoir du parallélisme et de l'asynchronicité en même temps, on obtient des performances plus hautes que la plupart des frameworks NodeJS et égales à celles du Go, qui est un langage compilé plus proche du C <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(tout ça grâce à Starlette)</a>.

 *  New: Fold `MockWebServerRule` into `MockWebServer`. This makes it easier to
    write JUnit tests with `MockWebServer`. The `MockWebServer` library now
    depends on JUnit, though it continues to work with all testing frameworks.
 *  Fix: `FormEncodingBuilder` is now consistent with browsers in which
    characters it escapes. Previously we weren’t percent-encoding commas,
    parens, and other characters.

Und das ist das gleiche Leistungsniveau, das Sie mit **FastAPI** erhalten.

Und da Sie Parallelität und Asynchronität gleichzeitig haben können, erzielen Sie eine höhere Performanz als die meisten getesteten NodeJS-Frameworks und sind mit Go auf Augenhöhe, einer kompilierten Sprache, die näher an C liegt <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(alles dank Starlette)</a>.

    the entire connection to fail.
 *  Fix: Don’t crash on unexpected charsets in the logging interceptor.
 *  Fix: `OkHttpClient` is now non-final for the benefit of mocking frameworks.
    Mocking sophisticated classes like `OkHttpClient` is fragile and you
    shouldn’t do it. But if that’s how you want to live your life we won’t stand
    in your way!


## Version 3.0.1

    * Se você quer fazer comparações com o FastAPI, compare com um _framework_  (ou conjunto de ferramentas) para aplicações _web_ que forneça validação de dados, serialização e documentação, como Flask-apispec, NestJS, Molten, etc. _Frameworks_ com validação de dados automática, serialização e documentação integradas....
