通过 **FastAPI** 你可以获得所有 **Starlette** 的特性 ( FastAPI 就像加强版的 Starlette )：

* 令人惊叹的性能。它是 <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">Python 可用的最快的框架之一，和 **NodeJS** 及 **Go** 相当</a>。
* **支持 WebSocket** 。
* **支持 GraphQL** 。
* 后台任务处理。
* Startup 和 shutdown 事件。
* 测试客户端基于 HTTPX。

Isso ocorre por que, por padrão, o FastAPI irá verificar cada item dentro do dicionário e garantir que ele seja serializável para JSON, utilizando o mesmo[Codificador Compatível com JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado no tutorial. Isso permite que você retorne **objetos abstratos**, como modelos do banco de dados, por exemplo.
