# 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.

### エディタのサポート

すべてのフレームワークは使いやすく直感的に使用できるように設計されており、すべての決定は開発を開始する前でも複数のエディターでテストされ、最高の開発体験が保証されます。

前回のPython開発者調査では、<a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">最も使用されている機能が「オートコンプリート」であることが明らかになりました。</a>

**FastAPI** フレームワークは、この要求を満たすことを基本としています。オートコンプリートはどこでも機能します。

ドキュメントに戻る必要はほとんどありません。

エディターがどのように役立つかを以下に示します:

- golang.org/x/time: 9d24e82 → 555d28b
- golang.org/x/tools: 65e3620 → c1934b7
- golang.org/x/xerrors: a985d34 → 9bdfabe
- google.golang.org/api: 5213b80 → v0.15.1
- google.golang.org/appengine: v1.5.0 → v1.6.5
- google.golang.org/genproto: 24fa4b2 → cb27e3a
- google.golang.org/grpc: v1.26.0 → v1.27.0
- gopkg.in/check.v1: 788fd78 → 41f04d3
- honnef.co/go/tools: v0.0.1-2019.2.2 → v0.0.1-2019.2.3

for use by the garbage collector; they are introduced by the compiler.

To see what gets put in the binary after linking, use <code>go tool objdump</code>:
</p>

<pre>
$ go build -o x.exe x.go
$ go tool objdump -s main.main x.exe
TEXT main.main(SB) /tmp/x.go
  x.go:3		0x10501c0		65488b0c2530000000	MOVQ GS:0x30, CX

Ele utiliza <a href="https://github.com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a> ao invés do '_loop_' `asyncio` padrão do Python. É isso que deixa ele tão rápido.

Ele claramente inspirou Uvicorn e Starlette, que são atualmente mais rápidos que o Sanic em testes de performance abertos.

Ayrıca ilginç ve çok rastlanmayan bir özelliği vardı: aynı framework'ü kullanarak hem API'lar hem de <abbr title="Command Line Tool (CLI): Komut satırı aracı">CLI</abbr>'lar oluşturmak mümkündü.

Senkron çalışan Python web framework'lerinin standardına (WSGI) dayandığından dolayı Websocket'leri ve diğer şeyleri işleyemiyor, ancak yine de yüksek performansa sahip.
