## Dependencias

FastAPI depende de Pydantic y Starlette.

### Dependencias `standard`

Cuando instalas FastAPI con `pip install "fastapi[standard]"` viene con el grupo `standard` de dependencias opcionales:

Usadas por Pydantic:

## Dependências

O FastAPI depende do Pydantic e do Starlette.


### Dependências `standard`

Quando você instala o FastAPI com `pip install "fastapi[standard]"`, ele vêm com o grupo `standard` (padrão) de dependências opcionais:

    assertThat(Doubles.toArray(list.subList(1, 3))).isEqualTo(new double[] {1.0, 2.0});
    assertThat(Doubles.toArray(list.subList(2, 2))).isEmpty();
  }

  // `primitives` can't depend on `collect`, so this is what the prod code has to return.
  @SuppressWarnings("EmptyList")
  public void testAsListEmpty() {
    assertThat(Doubles.asList(EMPTY)).isSameInstanceAs(Collections.emptyList());
  }

    assertThat(Ints.toArray(list.subList(1, 3))).isEqualTo(new int[] {(int) 1, (int) 2});
    assertThat(Ints.toArray(list.subList(2, 2))).isEqualTo(new int[] {});
  }

  // `primitives` can't depend on `collect`, so this is what the prod code has to return.
  @SuppressWarnings("EmptyList")
  public void testAsListEmpty() {
    assertThat(Ints.asList(EMPTY)).isSameInstanceAs(Collections.emptyList());
  }

In that case, you wouldn't have to worry about any of this. 🤷

This will **depend heavily** on the way you **deploy your system**, and it would probably be connected to the way you start programs, handling restarts, etc.

Here are some possible ideas:

    assertThat(Doubles.toArray(list.subList(1, 3))).isEqualTo(new double[] {1.0, 2.0});
    assertThat(Doubles.toArray(list.subList(2, 2))).isEmpty();
  }

  // `primitives` can't depend on `collect`, so this is what the prod code has to return.
  @SuppressWarnings("EmptyList")
  public void testAsListEmpty() {
    assertThat(Doubles.asList(EMPTY)).isSameInstanceAs(Collections.emptyList());
  }

    assertThat(Longs.toArray(list.subList(1, 3))).isEqualTo(new long[] {1L, 2L});
    assertThat(Longs.toArray(list.subList(2, 2))).isEqualTo(new long[] {});
  }

  // `primitives` can't depend on `collect`, so this is what the prod code has to return.
  @SuppressWarnings("EmptyList")
  public void testAsListEmpty() {
    assertThat(Longs.asList(EMPTY)).isSameInstanceAs(Collections.emptyList());
  }

    assertThat(Shorts.toArray(list.subList(1, 3))).isEqualTo(new short[] {(short) 1, (short) 2});
    assertThat(Shorts.toArray(list.subList(2, 2))).isEqualTo(new short[] {});
  }

  // `primitives` can't depend on `collect`, so this is what the prod code has to return.
  @SuppressWarnings("EmptyList")
  public void testAsListEmpty() {
    assertThat(Shorts.asList(EMPTY)).isSameInstanceAs(Collections.emptyList());
  }
