Then APIStar stopped to exist as a server and Starlette was created, and was a new better foundation for such a system. That was the final inspiration to build **FastAPI**.

    I consider **FastAPI** a "spiritual successor" to APIStar, while improving and increasing the features, typing system, and other parts, based on the learnings from all these previous tools.

## Used by **FastAPI**

    * To wszystko będzie również działać dla głęboko zagnieżdżonych obiektów JSON.
* Automatycznie konwertuje z i do JSON.
* Dokumentuje wszystko w OpenAPI, które może być używane przez:
    * Interaktywne systemy dokumentacji.
    * Systemy automatycznego generowania kodu klienckiego, dla wielu języków.
* Dostarczy bezpośrednio 2 interaktywne dokumentacje webowe.

* The **file** that can be **executed** by the operating system, for example: `python`, `python.exe` or `uvicorn`.
* A particular program while it is **running** on the operating system, using the CPU, and storing things on memory. This is also called a **process**.

### What is a Process

The word **process** is normally used in a more specific way, only referring to the thing that is running in the operating system (like in the last point above):

    "Operating System :: OS Independent",
    "Programming Language :: Python :: 3",
    "Programming Language :: Python",
    "Topic :: Internet",
    "Topic :: Software Development :: Libraries :: Application Frameworks",
    "Topic :: Software Development :: Libraries :: Python Modules",
    "Topic :: Software Development :: Libraries",
    "Topic :: Software Development",
    "Typing :: Typed",

That way, you can create a token with an expiration of, let's say, 1 week. And then when the user comes back the next day with the token, you know that user is still logged in to your system.

    * Tutto questo funzionerebbe anche con oggetti JSON più complessi.
* Convertirà *da* e *a* JSON automaticamente.
* Documenterà tutto con OpenAPI, che può essere usato per:
    * Sistemi di documentazione interattivi.
    * Sistemi di generazione di codice dal lato client, per molti linguaggi.
* Fornirà 2 interfacce di documentazione dell'API interattive.

### Примеры инструментов, управляющих запуском программ

Вот несколько примеров, которые могут справиться с такой задачей:

* Docker
* Kubernetes
* Docker Compose
* Docker в режиме Swarm
* Systemd
* Supervisor
* Использование услуг облачного провайдера
* Прочие...

Я покажу Вам некоторые примеры их использования в следующих главах.

## Перезапуск

                        "content": {
                            "application/json": {



...
```

#### What is OpenAPI for

The OpenAPI schema is what powers the two interactive documentation systems included.

And there are dozens of alternatives, all based on OpenAPI. You could easily add any of those alternatives to your application built with **FastAPI**.

これを実現するために、通常は**別のプログラム**を用意し、起動時にアプリケーションが実行されるようにします。そして多くの場合、他のコンポーネントやアプリケーション、例えばデータベースも実行されるようにします。

### 起動時に実行するツールの例

実行するツールの例をいくつか挙げます:

* Docker
* Kubernetes
* Docker Compose
* Swarm モードによる Docker
* Systemd
* Supervisor
* クラウドプロバイダーがサービスの一部として内部的に処理
* そのほか...

次の章で、より具体的な例を挙げていきます。

## 再起動

起動時にアプリケーションが実行されることを確認するのと同様に、失敗後にアプリケーションが**再起動**されることも確認したいと思われます。

### 我々は間違いを犯す

The simplicity of the dependency injection system makes **FastAPI** compatible with:

* all the relational databases
* NoSQL databases
* external packages
* external APIs
* authentication and authorization systems
* API usage monitoring systems
* response data injection systems
* etc.
