웹 API 대신 터미널에서 사용할 <abbr title="Command Line Interface">CLI</abbr> 앱을 만들고 있다면, <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>를 확인해 보십시오.

**Typer**는 FastAPI의 동생입니다. 그리고 **FastAPI의 CLI**가 되기 위해 생겼습니다. ⌨️ 🚀

## 요구사항

## `Annotated`인 의존성 공유하기

위의 예제에서 몇몇 작은 **코드 중복**이 있다는 것을 보았을 겁니다.

`common_parameters()`의존을 사용해야 한다면, 타입 명시와 `Depends()`와 함께 전체 매개변수를 적어야 합니다:

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

하지만 `Annotated`를 사용하고 있기에, `Annotated` 값을 변수에 저장하고 여러 장소에서 사용할 수 있습니다:

//// tab | Python 3.10+

```Python hl_lines="12  16  21"

    for (int i = 0; i < elementCount; i++) {
      E element = (E) stream.readObject();
      add(element);
    }
  }

  /*
   * For discussion of the safety of the following methods, see the comments near the end of
   * CompactHashMap.
   */

  private Object requireTable() {
    return requireNonNull(table);
  }

  private int[] requireEntries() {
    return requireNonNull(entries);
  }

  public NullPointerTester() {
    try {
      /*
       * Converter.apply has a non-nullable parameter type but doesn't throw for null arguments. For
       * more information, see the comments in that class.
       *
       * We already know that that's how it behaves, and subclasses of Converter can't change that
       * behavior. So there's no sense in making all subclass authors exclude the method from any

 *  Fix: Don't crash when the URL hostname contains an underscore on Android.
 *  Fix: Change HTTP/2 to use a daemon thread for its socket reader. If you've ever seen a command
    line application hang after all of the work is done, it may be due to a non-daemon thread like
    this one.
