/// tip | Tipp

Das *Herunterfahren* würde erfolgen, wenn Sie die Anwendung **stoppen**.

Möglicherweise müssen Sie eine neue Version starten, oder Sie haben es einfach satt, sie auszuführen. 🤷

### Lifespan-Funktion

Das Erste, was auffällt, ist, dass wir eine asynchrone Funktion mit `yield` definieren. Das ist sehr ähnlich zu Abhängigkeiten mit `yield`.

**Typer** is het kleine broertje van FastAPI. En het is bedoeld als de **FastAPI van CLI's**. ️

## Vereisten

FastAPI staat op de schouders van reuzen:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> voor de webonderdelen.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> voor de datadelen.

## Installatie

<div class="termy">

        return instance;
    }

    /**
     * Starts the process.
     */
    public synchronized void start() {
        if (thread == null) {
            thread = new Thread(this, "CoreLib-TimeoutManager");
            thread.setDaemon(true);
            thread.start();
            if (logger.isDebugEnabled()) {
                logger.debug("TimeoutManager started.");
            }
        }
    }

    /**

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

### Starten

Führen Sie den Server aus:

<div class="termy">

```console
$ uvicorn main:app --reload

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [28720]

**Typer** is FastAPI's little sibling. And it's intended to be the **FastAPI of CLIs**. ⌨️ 🚀

## Requirements { #requirements }

FastAPI stands on the shoulders of giants:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> for the web parts.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> for the data parts.

## Installation { #installation }

`FastAPI`, API'niz için tüm işlevselliği sağlayan bir Python sınıfıdır.

/// note | Teknik Detaylar

`FastAPI` doğrudan `Starlette`'i miras alan bir sınıftır.

<a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a>'in tüm işlevselliğini `FastAPI` ile de kullanabilirsiniz.

### Adım 2: Bir `FastAPI` "Örneği" Oluşturalım

`FastAPI` is a Python class that provides all the functionality for your API.

/// note | Technical Details

`FastAPI` is a class that inherits directly from `Starlette`.

You can use all the <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> functionality with `FastAPI` too.
