    But it was updated to use Python-jose instead as it provides all the features from PyJWT plus some extras that you might need later when building integrations with other tools.

## Password hashing

"Hashing" means converting some content (a password in this case) into a sequence of bytes (just a string) that looks like gibberish.

And we as developers keep improving the code as we find those bugs and as we implement new features (possibly adding new bugs too 😅).

### Small Errors Automatically Handled

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

# Bigger Applications - Multiple Files

If you are building an application or a web API, it's rarely the case that you can put everything on a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

!!! info
    If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure

Let's say you have a file structure like this:

```
.
├── app

```

### Construa a imagem Docker

* Vá para o diretório do projeto (onde seu `Dockerfile` está, contendo seu diretório `app`.
* Construa sua imagem FastAPI:

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

### Inicie o container Docker

* Rode um container baseado em sua imagem:

<div class="termy">

```console

Bauen Sie dazu zunächst die gesamte Dokumentation:

<div class="termy">

```console
// Verwenden Sie das Kommando „build-all“, das wird ein wenig dauern
$ python ./scripts/docs.py build-all

Building docs for: en
Building docs for: es
Successfully built docs for: es
```

</div>

<div class="termy">

```console
// Use the command "build-all", this will take a bit
$ python ./scripts/docs.py build-all

Updating es
Updating en

Copying en index.md to README.md
```

但是当你完成翻译后，你可以像在线上展示一样测试所有内容，包括所有其他语言。

为此，首先构建所有文档：

<div class="termy">

```console
// Use the command "build-all", this will take a bit
$ python ./scripts/docs.py build-all

Building docs for: en
Building docs for: es
Successfully built docs for: es
```

</div>

这样会对每一种语言构建一个独立的文档站点，并最终把这些站点全部打包输出到 `./site/` 目录。
