```console
$ ./traefik --configFile=traefik.toml

And now start your app, using the `--root-path` option:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

{* ../../docs_src/events/tutorial002_py39.py hl[6] *}

Here, the `shutdown` event handler function will write a text line `"Application shutdown"` to a file `log.txt`.

/// info

In the `open()` function, the `mode="a"` means "append", so, the line will be added after whatever is on that file, without overwriting the previous contents.

///

/// tip

{* ../../docs_src/events/tutorial002_py39.py hl[6] *}

Aqui, a função de manipulador do evento `shutdown` escreverá uma linha de texto `"Application shutdown"` no arquivo `log.txt`.

/// info | Informação

Na função `open()`, o `mode="a"` significa "acrescentar", então a linha será adicionada depois do que já estiver naquele arquivo, sem sobrescrever o conteúdo anterior.

При построении приложения или веб-API нам редко удается поместить всё в один файл.

**FastAPI** предоставляет удобный инструментарий, который позволяет нам структурировать приложение, сохраняя при этом всю необходимую гибкость.

/// info | Примечание

Если вы раньше использовали Flask, то это аналог шаблонов Flask (Flask's Blueprints).

## Пример структуры приложения { #an-example-file-structure }

# Моделі форм (Form Models)

У FastAPI Ви можете використовувати **Pydantic-моделі** для оголошення **полів форми**.

Щоб використовувати форми, спочатку встановіть <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">python-multipart</a>.
