Die einfachste FastAPI-Datei könnte wie folgt aussehen:

{* ../../docs_src/first_steps/tutorial001_py39.py *}

Kopieren Sie das in eine Datei `main.py`.

Starten Sie den Live-Server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

## Invoke Lambda transformation via PresignedGET

Following example shows how you can use [`minio-go` PresignedGetObject](https://docs.min.io/community/minio-object-store/developers/go/API.html#presignedgetobject-ctx-context-context-bucketname-objectname-string-expiry-time-duration-reqparams-url-values-url-url-error)
```go
package main

import (
	"context"
	"log"
	"net/url"
	"time"
	"fmt"

	"github.com/minio/minio-go/v7"

That way, you can edit the documentation/source files and see the changes live.

/// tip

Alternatively, you can perform the same steps that scripts does manually.

Go into the language directory, for the main docs in English it's at `docs/en/`:

```console
$ cd docs/en/
```

Then run `mkdocs` in that directory:

```console
$ mkdocs serve --dev-addr 127.0.0.1:8008
```

<summary>Über den Befehl <code>fastapi dev main.py</code> ...</summary>

Der Befehl `fastapi dev` liest Ihre `main.py`-Datei, erkennt die **FastAPI**-App darin und startet einen Server mit <a href="https://www.uvicorn.dev" class="external-link" target="_blank">Uvicorn</a>.

    /** The component <code>role</code> hint for Plexus container */
    String ROLE = Mojo.class.getName();

    /**
     * Perform whatever build-process behavior this <code>Mojo</code> implements.<br>
     * This is the main trigger for the <code>Mojo</code> inside the <code>Maven</code> system, and allows
     * the <code>Mojo</code> to communicate errors.
     *
     * @throws MojoExecutionException if an unexpected problem occurs.

### Проверьте автоматическую документацию API { #check-the-automatic-api-docs }

Теперь запустите команду `fastapi` с вашим файлом:

<div class="termy">

```console
$ fastapi dev main.py

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

</div>

        optimizedHelper.setProperty(bean2, "count", Integer.class, config2);
    }

    /**
     * Main method to run the JMH benchmark.
     *
     * @param args command line arguments
     * @throws RunnerException if the benchmark fails to run
     */
    public static void main(String[] args) throws RunnerException {
        Options opt = new OptionsBuilder()

 * <p>
 * This interface allows plugins and extensions to define and register additional project scopes
 * beyond the standard {@link ProjectScope#MAIN} and {@link ProjectScope#TEST} scopes.
 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism
 * and their provided project scopes will be available throughout the Maven build process.
 * <p>

It's relatively tightly coupled with relational databases (like MySQL or PostgreSQL), so, having a NoSQL database (like Couchbase, MongoDB, Cassandra, etc) as the main store engine is not very easy.

### Verifique a documentação automática da API { #check-the-automatic-api-docs }

Agora, execute o comando `fastapi` com o seu arquivo:

<div class="termy">

```console
$ fastapi dev main.py

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