# Bigger Applications - Multiple Files { #bigger-applications-multiple-files }

If you are building an application or a web API, it's rarely the case that you can put everything in 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 { #an-example-file-structure }

# 更大型的應用程式 - 多個檔案 { #bigger-applications-multiple-files }

如果你正在建置一個應用程式或 Web API，很少會把所有東西都放在單一檔案裡。

FastAPI 提供了一個方便的工具，讓你在維持彈性的同時，幫你組織應用程式的結構。

/// info | 資訊

如果你來自 Flask，這相當於 Flask 的 Blueprints。

///

## 範例檔案結構 { #an-example-file-structure }

假設你有如下的檔案結構：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   ├── dependencies.py
│   └── routers
│   │   ├── __init__.py
│   │   ├── items.py

# Большие приложения — несколько файлов { #bigger-applications-multiple-files }

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).

///

# Größere Anwendungen – mehrere Dateien { #bigger-applications-multiple-files }

Wenn Sie eine Anwendung oder eine Web-API erstellen, ist es selten der Fall, dass Sie alles in einer einzigen Datei unterbringen können.

**FastAPI** bietet ein praktisches Werkzeug zur Strukturierung Ihrer Anwendung bei gleichzeitiger Wahrung der Flexibilität.

/// info | Info

Wenn Sie von Flask kommen, wäre dies das Äquivalent zu Flasks Blueprints.

///

# 더 큰 애플리케이션 - 여러 파일 { #bigger-applications-multiple-files }

애플리케이션이나 웹 API를 만들 때, 모든 것을 하나의 파일에 담을 수 있는 경우는 드뭅니다.

**FastAPI**는 모든 유연성을 유지하면서도 애플리케이션을 구조화할 수 있게 해주는 편리한 도구를 제공합니다.

/// info | 정보

Flask를 사용해 보셨다면, 이는 Flask의 Blueprints에 해당하는 개념입니다.

///

## 예시 파일 구조 { #an-example-file-structure }

다음과 같은 파일 구조가 있다고 해봅시다:

```
