Preview, publish and undo an update

Let’s do this

1. 1
   In GitHub Desktop

   Get the latest files before editing

   Open the same project in GitHub Desktop and click Fetch origin. If it offers Pull origin and you have no conflicting local work, bring in the saved changes. If you already have edits, ask the AI to help preserve them first. Reopen the folder in your helper and restart the preview.

2. 2
   In GitHub Desktop

   Create a branch for a larger change

   A branch is a separate line of work. In GitHub Desktop use Current Branch, then New Branch, and name it improve-homepage. Have the AI make and test the change there. Commit it, then Publish branch or Push origin. Main stays as it was.

3. 3
   In Cloudflare

   Open the Cloudflare preview

   Pages normally builds other branches into preview deployments. Find yours under the Pages project’s Deployments and open its preview link. Test on your phone. Preview links are public by default, even when the GitHub repository is private. Use sample data; protected previews require a separate setup.

4. 4
   In GitHub

   Merge when you want it live

   Use GitHub Desktop’s Create Pull Request action, or Compare & pull request on GitHub. Review the change and checks, then merge into main. A pull request is a review page for joining the change to main. Cloudflare builds main again. Check that the latest successful deployment is the intended commit.

5. 5
   In Cloudflare and GitHub Desktop

   Undo both the live change and its source if needed

   For an urgent problem, Cloudflare can roll back to an earlier successful production deployment. Then revert the faulty commit in GitHub Desktop and push that correction to main, resolving any conflicts carefully. Rolling back hosting alone leaves the faulty source ready to return on a future build. A code rollback does not undo database changes.
