Refresh a pull request preview after a new commit
Help reviewers land on the newest preview after each new pull request commit.
Trigger
New Commit Added to Pull Request
Triggers when a new commit is pushed to a specific pull request. Monitors all commits on the specified pull request and emits an event for each newly added commit. This covers force-pushes and additional commits pushed to the PR's head branch.
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
Reviewers may inspect a stale cached preview and send feedback on code that has already changed.
- Refresh a preview when new code arrives.
- Keep review focused on the current build.
- Use a URL purge instead of clearing a whole zone.
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 monitored pull request and its public BunnyCDN preview URL.
- 4Pick New Commit Added to Pull Request as the trigger and choose where run reports go.
- 5Test with one real pull request commit and verify the preview URL was purged.
Questions about this workflow
Does a new commit mean the preview is already deployed?
Not necessarily. If deployment finishes later, use a deployment status event for the refresh instead.
How is the preview URL determined?
Name it in your instruction or provide a reliable way to identify it from the available run context.
Can this monitor a specific pull request?
Yes. The trigger monitors commits added to a specific pull request.
