### Dependencias

Lo mismo aplica para las [dependencias](tutorial/dependencies/index.md){.internal-link target=_blank}. Si una dependencia es una función estándar `def` en lugar de `async def`, se ejecuta en el threadpool externo.

### Sub-dependencias

    "groups" : [ {
      "testProject" : "springBootApp",
      "coverage" : {
        "per_day" : [ "linux" ]
      }
    } ]
  }, {
    "testId" : "org.gradle.performance.regression.corefeature.ParallelDownloadsPerformanceTest.resolves dependencies from external repository (parallel)",
    "groups" : [ {

}, {
  "scenario" : "org.gradle.performance.regression.corefeature.ParallelDownloadsPerformanceTest.resolves dependencies from external repository",
  "durations" : [ {
    "testProject" : "springBootApp",
    "linux" : 974
  } ]
}, {
  "scenario" : "org.gradle.performance.regression.corefeature.ParallelDownloadsPerformanceTest.resolves dependencies from external repository (parallel)",
  "durations" : [ {
    "testProject" : "springBootApp",

The dependency injection system requires pre-registration of the dependencies and the dependencies are solved based on the declared types. So, it's not possible to declare more than one "component" that provides a certain type.

## Recap { #recap }

不過，在這兩種情況下，**FastAPI** [仍然很快](index.md#_11){.internal-link target=_blank}至少與你之前的框架相當（或者更快）。

### 依賴項(Dependencies)

同樣適用於[依賴項](tutorial/dependencies/index.md){.internal-link target=_blank}。如果依賴項是一個標準的 `def` 函式，而不是 `async def`，那麼它在外部的執行緒池被運行。

### 子依賴項

///

### Lifespan function { #lifespan-function }

The first thing to notice, is that we are defining an async function with `yield`. This is very similar to Dependencies with `yield`.

{* ../../docs_src/events/tutorial003.py hl[14:19] *}

The first part of the function, before the `yield`, will be executed **before** the application starts.
