<pre><code class="python">"""Module for creating asyncio based apps

### Creating an async app

If you'd prefer to build your app with [asyncio](https://docs.python.org/3/library/asyncio.html), you can import the [AIOHTTP](https://docs.aiohttp.org/en/stable/) library and call the `AsyncApp` constructor. Within async apps, you can use the async/await pattern.

```bash

# Python 3.6+ required

python -m venv .venv

source .venv/bin/activate

pip install -U pip

# aiohttp is required

pip install slack_bolt aiohttp

```

In async apps, all middleware/listeners must be async functions. When calling utility methods (like `ack` and `say`) within these functions, it's required to use the `await` keyword.

```python

# Import the async app instead of the regular one

from slack_bolt.async_app import AsyncApp

app = AsyncApp()

@app.event("app_mention")

async def event_test(body, say, logger):

logger.info(body)

await say("What's up?")

@app.command("/hello-bolt-python")

async def command(ack, body, respond):

await ack()

await respond(f"Hi <@{body['user_id']}>!")

if __name__ == "__main__":

app.start(3000)

```

If you want to use another async Web framework (e.g., Sanic, FastAPI, Starlette), take a look at the built-in adapters and their examples.

* [The Bolt app examples](https://github.com/slackapi/bolt-python/tree/main/examples)

* [The built-in adapters](https://github.com/slackapi/bolt-python/tree/main/slack_bolt/adapter)

Apps can be run the same way as the synchronous example above. If you'd prefer another async Web framework (e.g., Sanic, FastAPI, Starlette), take a look at [the built-in adapters](https://github.com/slackapi/bolt-python/tree/main/slack_bolt/adapter) and their corresponding [examples](https://github.com/slackapi/bolt-python/tree/main/examples).
