# Dependências Globais { #global-dependencies }

Para alguns tipos de aplicação você pode querer adicionar dependências para toda a aplicação.

De forma semelhante a [adicionar `dependencies` aos *decoradores de operação de rota*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, você pode adicioná-las à aplicação `FastAPI`.

Nesse caso, elas serão aplicadas a todas as *operações de rota* da aplicação:

Все способы [добавления `dependencies` (зависимостей) в *декораторах операций пути*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} по-прежнему применимы, но в данном случае зависимости применяются ко всем *операциям пути* приложения.

## Зависимости для групп *операций пути* { #dependencies-for-groups-of-path-operations }

# Sub-dependencies { #sub-dependencies }

You can create dependencies that have **sub-dependencies**.

They can be as **deep** as you need them to be.

**FastAPI** will take care of solving them.

## First dependency "dependable" { #first-dependency-dependable }

You could create a first dependency ("dependable") like:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

# 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){.internal-link target=_blank}, you can add them to the `FastAPI` application.

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

Und alle Ideen aus dem Abschnitt über das [Hinzufügen von `dependencies` zu den *Pfadoperation-Dekoratoren*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} gelten weiterhin, aber in diesem Fall für alle *Pfadoperationen* in der App.

## Abhängigkeiten für Gruppen von *Pfadoperationen* { #dependencies-for-groups-of-path-operations }

Mehr dazu finden Sie in der Dokumentation zu [Abhängigkeiten mit `yield` – Frühes Beenden und `scope`](../tutorial/dependencies/dependencies-with-yield.md#early-exit-and-scope).

### Abhängigkeiten mit `yield` und `StreamingResponse`, Technische Details { #dependencies-with-yield-and-streamingresponse-technical-details }

# Unterabhängigkeiten { #sub-dependencies }

Sie können Abhängigkeiten erstellen, die **Unterabhängigkeiten** haben.

Diese können so **tief** verschachtelt sein, wie nötig.

**FastAPI** kümmert sich darum, sie aufzulösen.

## Erste Abhängigkeit, „Dependable“ { #first-dependency-dependable }

Sie könnten eine erste Abhängigkeit („Dependable“) wie folgt erstellen:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

# Testando Dependências com Sobreposições { #testing-dependencies-with-overrides }

## Sobrepondo dependências durante os testes { #overriding-dependencies-during-testing }

Existem alguns cenários onde você deseje sobrepor uma dependência durante os testes.

Você não quer que a dependência original execute (e nenhuma das subdependências que você possa ter).

# Dependencias Globales { #global-dependencies }

Para algunos tipos de aplicaciones, podrías querer agregar dependencias a toda la aplicación.

Similar a como puedes [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, puedes agregarlos a la aplicación de `FastAPI`.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:
