## Configure the `entrypoint` in `pyproject.toml` { #configure-the-entrypoint-in-pyproject-toml }

As your FastAPI `app` object lives in `app/main.py`, you can configure the `entrypoint` in your `pyproject.toml` file like this:

```toml
[tool.fastapi]
entrypoint = "app.main:app"
```

that is equivalent to importing like:

```python

          python-version-file: ".python-version"
      - name: Setup uv
        uses: astral-sh/setup-uv@v7
        with:
          enable-cache: true
          cache-dependency-glob: |
            pyproject.toml
            uv.lock
      - name: Install GitHub Actions dependencies
        run: uv sync --locked --no-dev --group github-actions
      - name: Update Topic Repos
        run: uv run ./scripts/topic_repos.py
        env:

         */
        public int prefmaxlen;
        /**
         * DFS enumeration structure containing results
         */
        public DfsEnumStruct info;
        /**
         * Total number of entries available
         */
        public NdrLong totalentries;

        /**
         * Constructs a NetrDfsEnumEx request
         * @param dfs_name the DFS name to enumerate

```bash
fastapi run
```

### Add an entrypoint in `pyproject.toml`

FastAPI CLI will read the entrypoint in `pyproject.toml` to know where the FastAPI app is declared.

```toml
[tool.fastapi]
entrypoint = "my_app.main:app"
```

### Use `fastapi` with a path

          python-version-file: ".python-version"
      - name: Setup uv
        uses: astral-sh/setup-uv@v7
        with:
          enable-cache: true
          cache-dependency-glob: |
            pyproject.toml
            uv.lock
      - name: Install Dependencies
        run: uv sync --locked --no-dev --group github-actions
      # Allow debugging with tmate
      - name: Setup tmate session

          python-version-file: ".python-version"
      - name: Setup uv
        uses: astral-sh/setup-uv@v7
        with:
          enable-cache: true
          cache-dependency-glob: |
            pyproject.toml
            uv.lock
      - name: Install Dependencies
        run: uv sync --locked --no-dev --group github-actions
      # Allow debugging with tmate
      - name: Setup tmate session

        with:
          python-version-file: ".python-version"
      - name: Setup uv
        uses: astral-sh/setup-uv@v7
        with:
          cache-dependency-glob: |
            pyproject.toml
            uv.lock
      - run: uv sync --locked --no-dev --group github-actions
      - uses: actions/download-artifact@v8
        with:
          name: coverage-html
          path: htmlcov

      with:
        python-version-file: ".python-version"
    - name: Setup uv
      uses: astral-sh/setup-uv@v7
      with:
        enable-cache: true
        cache-dependency-glob: |
            pyproject.toml
            uv.lock
    - name: Install GitHub Actions dependencies
      run: uv sync --locked --no-dev --group github-actions
    - name: Label Approved
      run: uv run ./scripts/label_approved.py
      env:

次の内容で `traefik.toml` というファイルを作成します:

```TOML hl_lines="3"
[entryPoints]
  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

これは Traefik にポート 9999 で待ち受け、別のファイル `routes.toml` を使用するよう指示します。

/// tip | 豆知識

標準の HTTP ポート 80 ではなく 9999 を使うのは、管理者（`sudo`）権限で実行する必要をなくすためです。

## 콜백이 있는 앱 { #an-app-with-callbacks }

예시로 확인해 보겠습니다.

청구서를 생성할 수 있는 앱을 개발한다고 가정해 보세요.

이 청구서는 `id`, `title`(선택 사항), `customer`, `total`을 갖습니다.

여러분의 API 사용자(외부 개발자)는 POST 요청으로 여러분의 API에서 청구서를 생성합니다.

그 다음 여러분의 API는(가정해 보면):

* 청구서를 외부 개발자의 고객에게 전송합니다.
* 돈을 수금합니다.
* API 사용자(외부 개발자)의 API로 다시 알림을 보냅니다.
