### Generate a TypeScript Client with Tags { #generate-a-typescript-client-with-tags }

If you generate a client for a FastAPI app using tags, it will normally also separate the client code based on the tags.

This way, you will be able to have things ordered and grouped correctly for the client code:

In this case, you have:

Вы также получите автозавершение для отправляемой полезной нагрузки:

/// tip | Совет

Обратите внимание на автозавершение для `name` и `price`, это было определено в приложении FastAPI, в модели `Item`.

Ahora puedes importar y usar el código del cliente. Podría verse así, nota que tienes autocompletado para los métodos:

<img src="/img/tutorial/generate-clients/image02.png">

También obtendrás autocompletado para el payload a enviar:

<img src="/img/tutorial/generate-clients/image03.png">

/// tip | Consejo

Nota el autocompletado para `name` y `price`, que fue definido en la aplicación de FastAPI, en el modelo `Item`.

Sie werden auch eine automatische Vervollständigung für die zu sendende Payload erhalten:

Agora você pode importar e usar o código do cliente. Poderia ser assim, observe que você obtém preenchimento automático para os métodos:

<img src="/img/tutorial/generate-clients/image02.png">

Você também obterá preenchimento automático para o corpo a ser enviado:

Observe o preenchimento automático para `name` e `price`, que foi definido na aplicação FastAPI, no modelo `Item`.

        readmeTemplates.convention(layout.projectDirectory.dir("src/samples/readme-templates"))
        target.convention(layout.buildDirectory.dir("generated-samples/$buildInitType" + if (modularizationOption.isMulti()) "-with-libraries" else ""))
        type = buildInitType
        modularization = modularizationOption
    }
    samples.publishedSamples.create(sampleName) {

First, write all your **FastAPI** application as normally:

{* ../../docs_src/extending_openapi/tutorial001_py39.py hl[1,4,7:9] *}

### Generate the OpenAPI schema { #generate-the-openapi-schema }

Then, use the same utility function to generate the OpenAPI schema, inside a `custom_openapi()` function:

{* ../../docs_src/extending_openapi/tutorial001_py39.py hl[2,15:21] *}

```

### 3.2 Use OpenSSL to Generate a Certificate

Use one of the following methods to generate a certificate using `openssl`:

* 3.2.1 [Generate a private key with ECDSA](#generate-private-key-with-ecdsa)
* 3.2.2 [Generate a private key with RSA](#generate-private-key-with-rsa)
* 3.2.3 [Generate a self-signed certificate](#generate-a-self-signed-certificate)

#### 3.2.1 Generate a private key with ECDSA

                Customize the function used to generate unique IDs for the *path
                operations* shown in the generated OpenAPI.

                This is particularly useful when automatically generating clients or
                SDKs for your API.

                Read more about it in the
                [FastAPI docs about how to Generate Clients](https://fastapi.tiangolo.com/advanced/generate-clients/#custom-generate-unique-id-function).
