Hug inspiró a **FastAPI** a declarar un parámetro `response` en funciones para configurar headers y cookies.

Justo antes de decidir construir **FastAPI** encontré **APIStar** server. Tenía casi todo lo que estaba buscando y tenía un gran diseño.

### [APIStar](https://github.com/encode/apistar) (<= 0.5) { #apistar-0-5 }

Right before deciding to build **FastAPI** I found **APIStar** server. It had almost everything I was looking for and had a great design.

Se você já tem uma conta na **FastAPI Cloud** (nós convidamos você da lista de espera 😉), pode implantar sua aplicação com um único comando.

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

Hug 促使 **FastAPI** 使用 Python 类型提示来声明参数，并自动生成定义整个 API 的模式。

Hug 启发 **FastAPI** 在函数中声明 `response` 参数，用于设置 headers 与 cookies。

### [APIStar](https://github.com/encode/apistar) (<= 0.5) { #apistar-0-5 }

就在决定动手构建 **FastAPI** 之前，我找到了 **APIStar** 服务器。它几乎具备我想要的一切，设计也很出色。

在我见过的框架中，它是最早使用 Python 类型提示来声明参数和请求的实现之一（早于 NestJS 与 Molten）。我与 Hug 几乎同时发现了它。但 APIStar 使用了 OpenAPI 标准。
