# Créer des applications plus grandes - Plusieurs fichiers { #bigger-applications-multiple-files }

Si vous créez une application ou une API web, il est rare que vous puissiez tout mettre dans un seul fichier.

**FastAPI** fournit un outil pratique pour structurer votre application tout en conservant toute la flexibilité.

Si vous venez de Flask, cela équivaut aux Blueprints de Flask.

**FastAPI** proporciona una herramienta conveniente para estructurar tu aplicación manteniendo toda la flexibilidad.

**FastAPI** 提供了一个方便的工具，可以在保持所有灵活性的同时构建你的应用程序。

## 一个文件结构示例 { #an-example-file-structure }

假设你的文件结构如下：

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

# 大規模アプリケーション - 複数ファイル { #bigger-applications-multiple-files }

アプリケーションや Web API を作る場合、すべてを1つのファイルに収められることはほとんどありません。

**FastAPI** は、柔軟性を保ったままアプリケーションを構造化できる便利なツールを提供します。

/// info | 情報

Flask 出身であれば、Flask の Blueprint に相当します。

## 例のファイル構成 { #an-example-file-structure }

次のようなファイル構成があるとします:

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

     *
     * signum is 1 if p and q are both nonnegative or both negative, and -1 otherwise.

    int signum = 1 | ((p ^ q) >> (Integer.SIZE - 1));

* A certificate signed by a CA contains information about the issued identity (e.g. name, expiry, public key) and any intermediate certificates. The root CA is not included.

## 3. Generate and use Self-signed Keys and Certificates with MinIO

This section describes how to generate a self-signed certificate using various tools:
