✨ Released the React tag details screen by 9larsons · Pull Request #30377 · TryGhost/Ghost

9larsons · 2026-08-31T13:29:21Z

Summary

Promotes the tagDetailsReact Labs flag to generally available, so every site serves /tags/:slug and /tags/new from the React tag detail screen.

tagDetailsReact moves from PRIVATE_FEATURES to GA_FEATURES in ghost/core/core/shared/labs.js. Self-hosted sites never read the remote flag manifest, so this is what actually puts them on the React screen; Ghost(Pro) keeps a kill switch because remote overrides still sit above the GA list.
The private Labs toggle is removed from the settings UI, since the flag can no longer be turned off from there.
The tag detail e2e suite ran every journey against both implementations behind the flag; with the Ember branch unreachable, the dual-implementation loop is removed and the file states the behaviour contract once.
The page object's deleteTag() checked for the React actions menu with an immediate isVisible() and fell back to Ember's inline delete button. On client-side navigation that check raced the screen's tag fetch and the helper then hung waiting on a button React never renders. It now drives the React actions menu directly, with Playwright's auto-waiting.

Flag cleanup (removing tagDetailsReact from the gate components and deleting the Ember tag screen) is intentionally left for a follow-up, matching how previous screen releases were sequenced.

Verification

ghost/core: labs unit tests pass.
apps/admin: typecheck, tag-detail-gate unit tests, and the tag detail acceptance suite (33 tests) pass.
e2e: lint and typecheck pass; tests/admin/tags/ passes against a dev-mode Ghost with CI retry settings. The remaining first-attempt flakes in editor.test.ts are pre-existing shared-state order dependence (reproduced identically with the flag forced off) and are unrelated to this change.

Walkthrough

The React tag details screen is now always enabled through GA_FEATURES and is removed from the private labs feature list. Tag deletion uses the actions menu path without the previous direct-delete fallback. The E2E tag detail tests no longer run for both Ember and React; edit, create, and delete scenarios run once against React.

Merge Risk: ⚪ Minimal · up to bbce9

The release routes tag detail pages through the React implementation and updates the supporting test helper accordingly. No actionable merge-blocking risk remains after normal checks and review.

Full details: Type-Safe Boundaries

Explanation

No explicit type-safety failure was introduced. The production TypeScript change only removes a Labs UI entry, and the page-object and test changes are test code, which the check excludes. The only production behavior addition is the tagDetailsReact string in the pre-existing JavaScript GA_FEATURES list; it does not consume boundary data. The diff adds no any, unchecked as, @ts-nocheck, @ts-ignore, or new handwritten type. The existing Feature type is unchanged.

Full details: New Files Are Typescript

Explanation

The pull request adds no new files. The diff against origin/main contains five modified paths, all present at the base revision. The only JavaScript-like path, ghost/core/core/shared/labs.js, has status M and exists in both base and HEAD. Therefore, the explicit failure condition is not met.

Retain an Ember-compatible delete path.

tagDetailsReact: false routes /tags/:slug to Ember. The Ember screen exposes data-test-button="delete-tag", but TagEditorPage.deleteTag() uses only React locators, so it can time out before the confirmation modal opens. Add an Ember path or retain the fallback.
