# Omgevingsvariabelen

/// tip

Als je al weet wat "omgevingsvariabelen" zijn en hoe je ze kunt gebruiken, kun je deze stap gerust overslaan.

///

Een omgevingsvariabele (ook bekend als "**env var**") is een variabele die **buiten** de Python-code leeft, in het **besturingssysteem** en die door je Python-code (of door andere programma's) kan worden gelezen.

# Environment Variables

/// tip

If you already know what "environment variables" are and how to use them, feel free to skip this.

///

An environment variable (also known as "**env var**") is a variable that lives **outside** of the Python code, in the **operating system**, and could be read by your Python code (or by other programs as well).

Bevorzugen Sie die `Annotated`-Version, falls möglich.

Prefira utilizar a versão `Annotated` se possível.

Como o **FastAPI** é baseado no padrão **ASGI**, é muito fácil integrar qualquer biblioteca **GraphQL** também compatível com ASGI.

Você pode combinar *operações de rota* normais do FastAPI com GraphQL na mesma aplicação.

/// tip | "Dica"

**GraphQL** resolve alguns casos de uso muito específicos.

Ele tem **vantagens** e **desvantagens** quando comparado a **web APIs** comuns.

server["Server auf http://127.0.0.1:8000/app"]

proxy --> server
```

/// tip | "Tipp"

Die IP `0.0.0.0` wird üblicherweise verwendet, um anzudeuten, dass das Programm alle auf diesem Computer/Server verfügbaren IPs abhört.

            // More stuff here

注意，自动生成服务器时，`url` 的值 `/api/v1` 提取自 `roog_path`。
