quart-tasks 0.5.0

Quart extension that provides scheduled background tasks

Quart-Tasks is a Quart extension that provides scheduled background tasks.

Quickstart

Quart-Tasks is used by associating it with an app and then registering scheduled tasks,

from quart import Quart
from quart_tasks import QuartTasks

app = Quart(__name__)
tasks = QuartTasks(app)

@tasks.cron("*/5 * * * *")  # every 5 minutes
async def infrequent_task():
    ...  # Do something

@tasks.cron(
    seconds="*/10",  # every 10 seconds
    minutes="*",
    hours="*",
    day_of_month="*",
    month="*",
    day_of_week="*",
)
async def frequent_task():
    ...  # Do something

@tasks.periodic(timedelta(seconds=10))
async def regular_task():
    ...  # Do Something

Note: the non-standard cron format (for seconds) is as defined by croniter.

The tasks will then run in the background as the app itself runs or they can be run manually via the CLI quart run-tasks.

To invoke a task immediately use the quart invoke-task [task_name] CLI command.
