Scheduled theme publishing, with Mechanic.

Mechanic is a development and ecommerce automation platform for Shopify. :)

Scheduled theme publishing

This task will allow you to schedule any number of themes to be published at future dates and times. When the task runs at its normally scheduled 10 minute interval, it will find the entry with the most recent configured date in the past, and if that theme is not currently published, then the task will publish it.

Runs every 10 minutes and when a user triggers the task. Configuration includes theme ids and publish dates.

Documentation

This task will allow you to schedule any number of themes to be published at future dates and times. When the task runs at its normally scheduled 10 minute interval, it will find the entry with the most recent configured date in the past, and if that theme is not currently published, then the task will publish it.

Within the Theme IDs and publish dates field, simply configure the theme IDs on the left along with the related publish dates on the right. Publish dates may be entered with a date and time, using a 24-hour clock, in the format YYYY-MM-DD HH:MM, or only with a date in the format YYYY-MM-DD, in which case the time would default to midnight.

Important notes:
- All times are in local shop time.
- The task will attempt to parse the configured dates and times, and will display an error at run time if any of them are unparsable in the expected format.
- While this task is active it may override any manual publishing actions.

Developer details

Mechanic is designed to benefit everybody: merchants, customers, developers, agencies, Gurus, everybody.

That’s why we make it easy to configure automation without code, why we make it easy to tweak the underlying code once tasks are installed, and why we publish it all here for everyone to learn from.
