In diesem Fall wird sie im Pfad `/subapi` gemountet:

### Die automatische API-Dokumentation testen { #check-the-automatic-api-docs }

Führen Sie nun den Befehl `fastapi` aus:

<div class="termy">

```console
$ fastapi dev

Ich habe seit mehreren Jahren APIs mit komplexen Anforderungen (maschinelles Lernen, verteilte Systeme, asynchrone Jobs, NoSQL-Datenbanken, usw.) erstellt und leitete mehrere Entwicklerteams.

Dabei musste ich viele Alternativen untersuchen, testen und nutzen.

Die Geschichte von **FastAPI** ist zu einem großen Teil die Geschichte seiner Vorgänger.

Wie im Abschnitt [Alternativen](alternatives.md) gesagt:

<blockquote markdown="1">

* editor (meaning component of IDE): редактор кода
* adopt (meaning start to use): использовать (or `начать использовать`)
* headers (meaning HTTP-headers): HTTP-заголовки
* cookie sessions: сессии с использованием cookie
* tested (adjective): протестированный
* middleware: middleware (don't translate, but add `промежуточный слой` if clarification is needed)
* path operation: операция пути (optionally clarify as `обработчик пути`)
