## Install dependencies { #install-dependencies }

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## Using `Jinja2Templates` { #using-jinja2templates }

import (
	"sync"
	"time"

	"github.com/minio/minio/internal/config"

// Batch job environment variables
const (
	ReplicationWorkersWait = "replication_workers_wait"
	KeyRotationWorkersWait = "keyrotation_workers_wait"

通过考虑这些概念，您将能够**评估和设计**部署**您自己的 API**的最佳方式。

在接下来的章节中，我将为您提供更多部署 FastAPI 应用程序的**具体方法**。

但现在，让我们仔细看一下这些重要的**概念**。 这些概念也适用于任何其他类型的 Web API。 💡

## 安全性 - HTTPS

在[上一章有关 HTTPS](https.md){.internal-link target=_blank} 中，我们了解了 HTTPS 如何为您的 API 提供加密。

我们还看到，HTTPS 通常由应用程序服务器的**外部**组件（**TLS 终止代理**）提供。

并且必须有某个东西负责**更新 HTTPS 证书**，它可以是相同的组件，也可以是不同的组件。


### HTTPS 示例工具

您可以用作 TLS 终止代理的一些工具包括：

* Traefik

Ainda, em ambas as situações, as chances são que o **FastAPI** [ainda será mais rápido](index.md#performance){.internal-link target=_blank} do que (ou ao menos comparável a) seu framework anterior.

### Dependências { #dependencies }

O mesmo se aplica para as [dependências](tutorial/dependencies/index.md){.internal-link target=_blank}. Se uma dependência tem as funções com padrão `def` ao invés de `async def`, ela é rodada no threadpool externo.

#### More details { #more-details }

Let's say your file is named `myapp.py`.

If you run it with:

<div class="termy">

```console
$ python myapp.py
```

</div>

then the internal variable `__name__` in your file, created automatically by Python, will have as value the string `"__main__"`.

So, the section:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

will run.
