Refresh a preview when a pull request is synchronized
Keep active pull request previews fresh by connecting GitHub's synchronization event to a targeted purge.
Trigger
Pull Request Event
Triggered when a pull request is opened, closed, or synchronized.
Action
Purge URL
Tool to purge a specific url from the bunnycdn cache. use when you need to invalidate a resource immediately after updating it.
Why this helps
A preview can remain stale after a pull request updates, interrupting an otherwise focused review.
- Respond to pull request synchronization events.
- Refresh the preview URL you identify.
- Reduce back-and-forth caused by outdated preview pages.
Setup
Build it in a few focused steps.
- 1Connect GitHub and BunnyCDN once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name and prompt.
- 3In one instruction, identify the pull request events to handle and the associated public preview URL.
- 4Pick Pull Request Event as the trigger and choose where run reports go.
- 5Test with one real synchronization and confirm the intended preview URL was purged.
Questions about this workflow
Which pull request changes can trigger this?
The event covers a pull request being opened, closed, or synchronized. State which event should cause a purge in your instruction.
Can I purge the preview after every pull request event?
You can tell Notis which event types should lead to a purge. Be specific so a close event does not cause an unwanted refresh.
Does this guarantee the preview deployment completed?
No. Use a successful deployment status event if the purge must wait for deployment success.
