# 이벤트: startup과 shutdown

필요에 따라 응용 프로그램이 시작되기 전이나 종료될 때 실행되는 이벤트 핸들러(함수)를 정의할 수 있습니다.

이 함수들은 `async def` 또는 평범하게 `def`으로 선언할 수 있습니다.

/// warning | "경고"

이벤트 핸들러는 주 응용 프로그램에서만 작동합니다. [하위 응용 프로그램 - 마운트](./sub-applications.md){.internal-link target=_blank}에서는 작동하지 않습니다.

///

## `startup` 이벤트

응용 프로그램을 시작하기 전에 실행하려는 함수를 "startup" 이벤트로 선언합니다:

```Python hl_lines="8"
{!../../docs_src/events/tutorial001.py!}
```

## Einstellungen in einem anderen Modul

Sie könnten diese Einstellungen in eine andere Moduldatei einfügen, wie Sie in [Größere Anwendungen – mehrere Dateien](../tutorial/bigger-applications.md){.internal-link target=_blank} gesehen haben.

Sie könnten beispielsweise eine Datei `config.py` haben mit:

```Python
{!../../docs_src/settings/app01/config.py!}
```

- Tooling API client. This a library that is embedded into applications, such as IDEs or CI agents, that allows them to act as a Gradle client.
- Worker processes. Long-running daemon processes that the Gradle daemon starts to run specific kinds of work, such as compilation or test execution.

This platform is agnostic to what kind of software is being developed.
It might be Java or Kotlin libraries running on the JVM, Gradle plugins, Android or iOS applications, C++ libraries, and so on.

This platform does not provide special support for a particular language or ecosystem.

### JVM platform

You can add middleware to **FastAPI** applications.

A "middleware" is a function that works with every **request** before it is processed by any specific *path operation*. And also with every **response** before returning it.

* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).

Docker Compose allows defining and running single host, multi-container Docker applications.
