```console
$ npm run generate-client

frontend-app@1.0.0 generate-client /home/user/code/frontend-app
> openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios
```

</div>

Ese comando generará código en `./src/client` y usará `axios` (el paquete HTTP de frontend) internamente.

### Prueba el Código del Cliente

### 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:

<img src="/img/tutorial/generate-clients/image06.png">

In this case, you have:

  "description": "",
  "main": "index.js",
  "scripts": {
    "generate-client": "openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios"
  },
  "author": "",
  "license": "",
  "devDependencies": {
    "@hey-api/openapi-ts": "^0.27.38",
    "typescript": "^4.6.2"
  }
}
```

Depois de ter esse script NPM `generate-client` lá, você pode executá-lo com:

<div class="termy">

  "description": "",
  "main": "index.js",
  "scripts": {
    "generate-client": "openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios"
  },
  "author": "",
  "license": "",
  "devDependencies": {
    "@hey-api/openapi-ts": "^0.27.38",
    "typescript": "^4.6.2"
  }
}
```

Nachdem Sie das NPM-Skript `generate-client` dort stehen haben, können Sie es ausführen mit:

<div class="termy">

        super();
    }

    /**
     * Generates a thumbnail for the specified ID and output file.
     * This implementation always returns false, indicating no thumbnail was generated.
     *
     * @param thumbnailId the ID of the thumbnail to generate
     * @param outputFile the output file where the thumbnail should be saved
     * @return false always, as this generator does not create thumbnails
     */
    @Override

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

{* ../../docs_src/extending_openapi/tutorial001.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.py hl[2,15:21] *}

   *       ImmutableList<String>};
   *   <li>of the raw type;
   *   <li>null if no value can be generated.
   * </ul>
   */
  final @Nullable Object generateFresh(TypeToken<?> type) {
    Object generated = generate(type);
    if (generated != null) {
      freshness.incrementAndGet();
    }
    return generated;
  }

  final <T> @Nullable T generateFresh(Class<T> type) {

```

### 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

   *       ImmutableList<String>};
   *   <li>of the raw type;
   *   <li>null if no value can be generated.
   * </ul>
   */
  final @Nullable Object generateFresh(TypeToken<?> type) {
    Object generated = generate(type);
    if (generated != null) {
      freshness.incrementAndGet();
    }
    return generated;
  }

  final <T> @Nullable T generateFresh(Class<T> type) {

        // Test generation with null thumbnail ID
        assertFalse(thumbnailGenerator.generate(null, tempOutputFile));
    }

    public void test_generate_withEmptyThumbnailId() {
        // Test generation with empty thumbnail ID
        assertFalse(thumbnailGenerator.generate("", tempOutputFile));
    }

    public void test_generate_withNullOutputFile() {
