Currently, the Netlify deployment previews of every Codex patch (e.g. https://820699--wikimedia-codex.netlify.app) only include the docs site, not the sandbox. If we allow contributors to initially demo new components in the sandbox without adding demos to the docs site, reviewers won't be able to see and test the new component implementation without downloading the patch locally. Similarly, the deployment preview for https://gerrit.wikimedia.org/r/c/design/codex/+/820178 doesn't display the changes made by that patch at all.
To address this, we should publish the sandbox as part of these deployment previews, e.g. under https://820178--wikimedia-codex.netlify.app/sandbox .
Acceptance Criteria
- Confirm that the sandbox page is properly generated as part of the deploy preview for an open component patch in Codex.
