# Global Dependencies { #global-dependencies }

For some types of applications you might want to add dependencies to the whole application.

Similar to the way you can [add `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md), you can add them to the `FastAPI` application.

In that case, they will be applied to all the *path operations* in the application:

{* ../../docs_src/dependencies/tutorial012_an_py310.py hl[17] *}

 * <p>If you know that a given string represents a numeric IP address, use {@link InetAddresses} to
 * obtain and manipulate a {@link java.net.InetAddress} instance from it rather than using this
 * class. Similarly, if you know that a given string represents a domain name, use {@link
 * InternetDomainName} rather than this class.

For example, to install Uvicorn:

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>

A similar process would apply to any other ASGI server program.

/// tip

By adding the `standard`, Uvicorn will install and use some recommended extra dependencies.

Por ejemplo, para instalar Uvicorn:

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%

</div>

Un proceso similar se aplicaría a cualquier otro programa de servidor ASGI.

/// tip | Consejo

Al añadir `standard`, Uvicorn instalará y usará algunas dependencias adicionales recomendadas.

### Siempre `raise` en Dependencias con `yield` y `except` { #always-raise-in-dependencies-with-yield-and-except }

Si capturas una excepción en una dependencia con `yield`, a menos que estés lanzando otra `HTTPException` o similar, **deberías volver a lanzar la excepción original**.
