Якщо ваш код має таку структуру:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

Тоді ви встановили б `entrypoint` як:

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

що еквівалентно:

```python
from backend.main import app
```

```

/// note

The command `uvicorn main:app` refers to:

* `main`: the file `main.py` (the Python "module").
* `app`: the object created inside of `main.py` with the line `app = FastAPI()`.

It is equivalent to:

```Python
from main import app
```

///

plugins {
    java
}

val validateTaskName = "validatePlugins"
val reportFileName = "task-properties/report.txt"

tasks.register<ValidatePlugins>(validateTaskName) {
    val main = project.sourceSets.main.get()
    classes.from(main.output)
    classpath.from(main.runtimeClasspath)
    outputFile = project.reporting.baseDirectory.file(reportFileName)
    enableStricterValidation = true

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)!
COPY ./main.py /code/

# (2)!
CMD ["fastapi", "run", "main.py", "--port", "80"]
```

1. Copy the `main.py` file to the `/code` directory directly (without any `./app` directory).

2. Use `fastapi run` to serve your application in the single file `main.py`.

Digamos que você tenha uma estrutura de arquivo conforme descrito em [Aplicações maiores](bigger-applications.md):

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

No arquivo `main.py` você tem sua aplicação **FastAPI**:

        #  Additional schemas have original settings apart from the main schema.
        #  The settings are objectTypeTargetList, tableExceptList,
        #  tableTargetList, and columnExceptMap.
        #  They have the same specification as ones of the main schema.

```python

```

Wenn Ihr Code so strukturiert wäre:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

Dann würden Sie den `entrypoint` wie folgt setzen:

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

was gleichbedeutend wäre mit:

```python
from backend.main import app
```
