### Dependency Injection

FastAPI incluye un sistema de <abbr title='En español: Inyección de Dependencias. También conocido en inglés cómo: "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> extremadamente poderoso y fácil de usar.

async def needy_dependency(fresh_value: str = Depends(get_value, use_cache=False)):
    return {"fresh_value": fresh_value}
```

## Recap

Apart from all the fancy words used here, the **Dependency Injection** system is quite simple.

Just functions that look the same as the *path operation functions*.

But still, it is very powerful, and allows you to declare arbitrarily deeply nested dependency "graphs" (trees).

### Dependency Injection

FastAPI bevat een uiterst eenvoudig, maar uiterst krachtig <abbr title='ook bekend als "componenten", "bronnen", "diensten", "aanbieders"'><strong>Dependency Injection</strong></abbr> systeem.

* Zelfs dependencies kunnen dependencies hebben, waardoor een hiërarchie of **“graph” van dependencies** ontstaat.
