## Mini App Example

You can find this example in our Github repository:

[ui-widgets-demos/thumbnail/003\_video\_thumbnail/src/main.py](https://github.com/supervisely-ecosystem/ui-widgets-demos/blob/master/thumbnail/003_video_thumbnail/src/main.py)

### Import libraries

```python
import os

import supervisely as sly
from dotenv import load_dotenv
from supervisely.app.widgets import Card, Container, VideoThumbnail
```

### Init API client

First, we load environment variables with credentials and init API for communicating with Supervisely Instance:

```python
load_dotenv("local.env")
load_dotenv(os.path.expanduser("~/supervisely.env"))

api = sly.Api()
```

### Initialize `VideoThumbnail` widget

```python
video_id = int(os.environ["modal.state.slyVideoId"])
video_info = api.video.get_info_by_id(id=video_id)

video_thumbnail = VideoThumbnail(info=video_info)
```

### Create app layout

Prepare a layout for app using `Card` widget with the `content` parameter and place widget that we've just created in the `Container` widget.

```python
card = Card(
    title="Video Thumbnail",
    content=Container(widgets=[video_thumbnail]),
)
layout = Container(widgets=[card])
```

### Create app using layout

Create an app object with layout parameter.

```python
app = sly.Application(layout=layout)
```
