# Démarrer { #first-steps }

Le fichier **FastAPI** le plus simple possible pourrait ressembler à ceci :

{* ../../docs_src/first_steps/tutorial001_py310.py *}

Copiez cela dans un fichier `main.py`.

Démarrez le serveur en direct :

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

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

	}
	inferTypeAsString(v1)
	s, ok := v1.ToString()
	if !ok {
		err := fmt.Errorf("Incorrect argument type passed to %s", sqlFnSubstring)
		return nil, errIncorrectSQLFunctionArgumentType(err)
	}

	// Assemble other arguments
	arg2, arg3 := e.From, e.For
	// Check if the second form of substring is being used
	if e.From == nil {
		arg2, arg3 = e.Arg2, e.Arg3
	}

	// Evaluate the FROM argument

```console
$ uv pip install -r requirements.txt
---> 100%
```

</div>

////

/// details | `requirements.txt`

Un `requirements.txt` avec quelques packages pourrait ressembler à :

```requirements.txt
fastapi[standard]==0.113.0
pydantic==2.8.0
```

## Exécuter votre programme { #run-your-program }

    ./gradlew -p distribution/archives/darwin-tar assemble

You will find the distribution under:

    ./distribution/archives/darwin-tar/build/distributions/

To create all build artifacts (e.g., plugins and Javadocs) as well as
distributions in all formats, run this command:

    ./gradlew assemble

> **NOTE:** Running the task above will fail if you don't have an available

				if err == nil {
					decReader = rah
					cFns = append([]func(){func() {
						rah.Close()
					}}, cFns...)
				}
			}
			oi.Size = decLength

			// Assemble the GetObjectReader
			r = &GetObjectReader{
				ObjInfo:    oi,
				Reader:     decReader,
				cleanUpFns: cFns,
			}
			return r, nil
		}

	case isEncrypted:
		var seqNumber uint32

## HTTPS pour les développeurs { #https-for-developers }

Voici un exemple de ce à quoi pourrait ressembler une API HTTPS, étape par étape, en portant principalement attention aux idées importantes pour les développeurs.

### Nom de domaine { #domain-name }

```Python
response = requests.get("http://example.com/some/url")
```

L’opération de chemin d'accès correspondante dans **FastAPI** pourrait ressembler à ceci :

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Notez les similitudes entre `requests.get(...)` et `@app.get(...)`.

options for running the tests for ES.

== Creating packages

To create a distribution without running the tests, simply run the
following:

-----------------------------
./gradlew assemble
-----------------------------

To create a platform-specific build including the x-pack modules, use the
following depending on your operating system:

-----------------------------

This is also referred to as // stitching, and provides significant performance...
