# Templates

Sie können jede gewünschte Template-Engine mit **FastAPI** verwenden.

Eine häufige Wahl ist Jinja2, dasselbe, was auch von Flask und anderen Tools verwendet wird.

Es gibt Werkzeuge zur einfachen Konfiguration, die Sie direkt in Ihrer **FastAPI**-Anwendung verwenden können (bereitgestellt von Starlette).

## Abhängigkeiten installieren

Installieren Sie `jinja2`:

<div class="termy">

```console
$ pip install jinja2

# Templates

Você pode usar qualquer template engine com o **FastAPI**.

Uma escolha comum é o Jinja2, o mesmo usado pelo Flask e outras ferramentas.

Existem utilitários para configurá-lo facilmente que você pode usar diretamente em sua aplicação **FastAPI** (fornecidos pelo Starlette).

## Instalação de dependências

Para instalar o `jinja2`, siga o código abaixo:

<div class="termy">

```console
$ pip install jinja2
```

 * Closer closer = Closer.create();
 * try {
 *   InputStream in = closer.register(openInputStream());
 *   OutputStream out = closer.register(openOutputStream());
 *   // do stuff
 * } catch (Throwable e) {
 *   // ensure that any checked exception types other than IOException that could be thrown are
 *   // provided here, e.g. throw closer.rethrow(e, CheckedException.class);
 *   throw closer.rethrow(e);
 * } finally {
 *   closer.close();

    return max(10L, Runtime.getRuntime().totalMemory() / (32L * 1024L * 1024L));
  }

### Criar um Engine
Um `engine` SQLModel (por baixo dos panos, ele é na verdade um `engine` do SQLAlchemy) é o que **mantém as conexões** com o banco de dados.

Você teria **um único objeto `engine`** para todo o seu código se conectar ao mesmo banco de dados.
