What settings cover
ThemeDocument settings are structured data, validated against the theme’s schema. They cover:- Colors, typography, spacing, and shape tokens
- Page and block content
- Block visibility and variants
- Approved custom CSS
Blocks and stable IDs
Each block on a page has a stable ID, a registered type, a visibility flag, and typed settings. The ID stays the same when you reorder or edit the block. A later automated update or an AI edit targets that ID, so a changed ID looks like a deleted block plus a new one. An unknown block type or an invalid setting fails validation. Shoppex does not select a fallback block or guess a value in its place.The editing loop
The Theme Builder holds the source of truth for a draft.1
Inspect
Open the page in the Builder, or fetch the current document and settings, before you change anything.
2
Edit
Change only the page, block, or setting you intend to update.
3
Preview
Check every page type that uses the changed block: product, collection, content, and system pages.
4
Save
Saving stores your draft. It does not change the live storefront.
5
Publish
Publishing validates the document and creates a new revision. Visitors see the new revision only after it completes.
Revisions and conflicts
Every publish creates a new revision. A published revision never changes afterwards, so a visitor never receives a half-written document. Another editor, an AI edit, or a CLI push can save a newer draft while you work. If that happens, your save or publish is rejected with a revision conflict instead of silently overwriting that work. If you get a revision conflict, reload the latest draft. Then reapply your change on top of it. For a self-hosted headless application, use@shoppexio/storefront instead of the Theme Builder. See Themes for how the two compare.
