### アプリの起動 { #run-the-app }

アプリを起動します:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

その後 `/docs` の UI にアクセスすると、FastAPI がこれらのモデルを使って API をドキュメント化し、同時にデータのシリアライズとバリデーションにも使っていることがわかります。

        doc2.put("title", "Quick Start");
        doc2.put("url", "http://example.com/start");
        msg.addSource(new ChatSource(2, doc2));

        final String result = chatClient.testBuildAssistantHistoryContent(msg, "source_titles", 500, 500);
        assertEquals("Response text\n[Referenced documents: Installation Guide, Quick Start]", result);
    }

// WalkDir will traverse a directory and return all entries found.
// On success a sorted meta cache stream will be returned.
// Metadata has data stripped, if any.
// The function tries to quit as fast as the context is canceled to avoid further drive IO

### 애플리케이션 실행하기 { #run-the-app }

애플리케이션을 실행할 수 있습니다:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

그런 다음 `/docs` UI로 이동하면, **FastAPI**가 이 **모델**들을 사용해 API를 **문서화**하고, 데이터를 **직렬화**하고 **검증**하는 데에도 사용하는 것을 확인할 수 있습니다.

<div class="screenshot">

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip | Consejo

Para establecer múltiples env vars para un solo comando, simplemente sepáralas con un espacio y ponlas todas antes del comando.

///

- **HTTP Client**: Apache HttpComponents
- **Content Extraction**: Apache Tika, Apache POI, PDFBox
- **Testing**: JUnit 4, UTFlute, Testcontainers
- **Storage Backends**: OpenSearch, Memory-based

## Quick Start

### Prerequisites

- Java 21 or higher
- Maven 3.6 or higher

### Installation

Add the following dependency to your `pom.xml`:

```xml
<dependency>

If you run the examples with, e.g.:

<div class="termy">

```console
$ fastapi dev tutorial001.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

as Uvicorn by default will use the port `8000`, the documentation on port `8008` won't clash.

### Translations

By declaring types for your variables, editors and tools can give you better support.

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.

**FastAPI** is all based on these type hints, they give it many advantages and benefits.
