# Scheduled Jobs

As in the [Technical Overview](/technical-overview), We use [Heroku
Scheduler](https://devcenter.heroku.com/articles/scheduler) for scheduled jobs.
As the name suggests, this is for regularly recurring tasks that need to be run
every day, week, month, year, decade, and century.

Tasks are implemented in `dev.to/lib/tasks/fetch.rake`, typically in the form
of:

```
task some_unique_task_name:, [optional_arg] => :environment do |optional_arg|
  ... do your thing here ...
end
```

You can explore the [official Heroku
documentation](https://devcenter.heroku.com/articles/scheduler#defining-tasks)
for defining tasks and read through tasks we have implemented for busting cache,
awarding badges, and more.

In your Pull Request, communicate with a DEV Core Team Member to discuss at what
frequency and ensure your task is scheduled on Heroku once your code is
reviewed, approved, and merged.
