### Lifespan function

The first thing to notice, is that we are defining an async function with `yield`. This is very similar to Dependencies with `yield`.

```Python hl_lines="14-19"
{!../../docs_src/events/tutorial003.py!}
```

The first part of the function, before the `yield`, will be executed **before** the application starts.

		[ $v1 == 0 -a $v2 == 0 ] && return 0
		sleep 10
	done
	return 1
}

function purge() {
	rm -rf "$1"
}

function fail() {
	for i in $(seq 1 3); do
		echo "server$i log:"
		cat "${WORK_DIR}/dist-minio-server$i.log"
	done
	pkill -9 minio
	echo "FAILED"
	purge "$WORK_DIR"
	exit 1
}

function __init__() {
	echo "Initializing environment"
	mkdir -p "$WORK_DIR"

            if (typeof moment !== 'function' && moment.hasOwnProperty('default')) moment = moment['default']
