## Create a TypeScript SDK { #create-a-typescript-sdk }

Let's start with a simple FastAPI application:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Notice that the *path operations* define the models they use for request payload and response payload, using the models `Item` and `ResponseMessage`.

### API Docs { #api-docs }

    return requireLinks()[i];
  }

  private void setLink(int i, long value) {
    requireLinks()[i] = value;
  }

  /*
   * We don't define getPredecessor+getSuccessor and setPredecessor+setSuccessor here because
   * they're defined above -- including logic to add and subtract 1 to map between the values stored
   * in the predecessor/successor arrays and the indexes in the elements array that they identify.
   */

            // Verify expected fields exist
            assertTrue("Should contain text field", mappings.contains("text"));
            assertTrue("Should define field types", mappings.contains("type"));
        }

        // Test settings content
        try (InputStream is = getClass().getClassLoader().getResourceAsStream("suggest_indices/suggest.json")) {

### Orden de las etiquetas { #order-of-tags }

El orden de cada diccionario de metadata de etiqueta también define el orden mostrado en la interfaz de documentación.

Por ejemplo, aunque `users` iría después de `items` en orden alfabético, se muestra antes porque agregamos su metadata como el primer diccionario en la list.

      assertTaskWrapped(tasks);
      lastMethodCalled = "invokeAllTimeout";
      lastTimeoutInMillis = unit.toMillis(timeout);
      return inline.invokeAll(tasks, timeout, unit);
    }

    // Define the invokeAny methods to invoke the first task
    @Override
    public <T> T invokeAny(Collection<? extends Callable<T>> tasks)
        throws ExecutionException, InterruptedException {
      assertTaskWrapped(tasks);

  pip install twine==3.6.0

# When cross-compiling with RBE, we need to copy the macOS sysroot to be
# inside the TensorFlow root directory. We then define them as a filegroup
# target inside "tensorflow/tools/toolchains/cross_compile/cc" so that Bazel
# can register it as an input to compile/link actions and send it to the remote
# VMs when needed.

/**
 * API action for admin file authentication management.
 * Provides RESTful API endpoints for managing file authentication settings in the Fess search engine.
 * File authentication settings define access credentials and permissions for file-based crawling.
 *
 */
public class ApiAdminFileauthAction extends FessApiAdminAction {

    private static final Logger logger = LogManager.getLogger(ApiAdminFileauthAction.class);

Following are advantages for using temporary credentials:

- Eliminates the need to embed long-term credentials with an application.
- Eliminates the need to provide access to buckets and objects without having to define static credentials.
- Temporary credentials have a limited lifetime, there is no need to rotate them or explicitly revoke them. Expired temporary credentials cannot be reused.

## Identity Federation

        return AbstractBaseGraph.this.nodeOrder();
      }

      @Override
      public ElementOrder<EndpointPair<N>> edgeOrder() {
        return ElementOrder.unordered(); // Graph doesn't define edge order
      }

      @Override
      public Set<N> adjacentNodes(N node) {
        return AbstractBaseGraph.this.adjacentNodes(node);
      }

      @Override

Así que, puedes declarar "objetos" JSON anidados profundamente con nombres de atributos específicos, tipos y validaciones.

Todo eso, de manera arbitraria.

### Definir un submodelo { #define-a-submodel }

Por ejemplo, podemos definir un modelo `Image`:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

### Usar el submodelo como tipo { #use-the-submodel-as-a-type }
