Added the post preview components to the React editor - #30481
Merged
Conversation
The React editor can show a post's title and body but has no way to see how that post will actually reach readers, which is the last check most people make before publishing. These components cover both halves of that check — the site render and the newsletter render — as a self-contained modal: one audience selection drives the browser preview's query params and the email preview's request, and the test send goes to a single address for that same audience. They are not wired into the editor header yet; the header that opens them lands with the publish controls, so this ships the surface and its tests on their own. The email render is shown through a srcdoc iframe sandboxed without scripts or same-origin access, rather than written into the frame's document.

Learning: Admin UI in Ghost is intentionally not localized. During code review, do not request adding i18n/translation hooks, wrappers, or new locale keys (e.g., updates to `packages/i18n/locales/en/ghost.json`) for Admin UI strings, including any React components under `apps/admin/src/`.

Review of the preview components turned up three ways the modal could show something wrong before it had anything to show. A post that has never been saved has no preview link, and the empty URL was being handed to the iframe and the share controls, so the frame loaded the admin app itself and the share actions pointed at nothing; that state now has its own empty view and disabled controls. The wait for the caller's save was starting in an effect, so the first commit mounted a frame against the pre-save URL and fetched stale content before remounting. The wait now starts during render, and a save that fails no longer falls through to a preview of the old server copy: the error is reported and the preview is replaced by a retry. Also: the email tab no longer flashes for a contributor while the current user loads, both newsletter labels read "Name <sender email>", and the post's own newsletter is honoured even when it is not on the active list.

The gate that holds the preview back until the caller's save resolves was reading a ref that is only refreshed after commit, so a caller that passes the save conditionally — the natural shape, since only a dirty post needs saving — handed it `undefined` on the very render that opens the modal: the save never ran and the preview showed the server's stale copy. It reads the prop now; the ref exists only to keep the effect from re-running when the callback's identity changes. The post's newsletter is also what its email renders as, so the modal now looks it up when it has left the active list, instead of the From line and the test send quietly falling back to the first active newsletter while the preview request used the post's. The test for the save gate sampled the DOM after effects had flushed, so it passed against the bug it was meant to catch; it now watches for any preview frame entering or leaving the page while the save is in flight.

beforeOpen.current() to reuse a single in-flight preparation promise during each
opening cycle, preventing duplicate onBeforeOpen calls under StrictMode effect
replay. Clear the cached promise when the modal closes and before Retry starts a
new preparation, and add an assertion that the initial open invokes onBeforeOpen
only once.

317-317: Keep preview-link actions disabled until preparation is ready.A failed save with a prior non-empty
previewUrlstill enables copying and opening stale content. RequireprepareState === 'ready'for both actions.Also applies to: 323-323
When a post's newsletter has been deleted, the lookup that keeps an off-list newsletter selectable comes back empty, and the From line was left naming nobody at the site's default address while the test send still fired with the dead slug and failed on the server. That case now says so and disables the send. It waits for the lookup to resolve, so a newsletter still being fetched is not mistaken for a missing one.

In `@apps/admin/src/editor/preview/post-preview-modal.tsx`:
- Line 127: Validate the Admin API response at its adapter boundary with a Zod
schema before accessing newsletters, including handling absent or null values
safely. Derive the response TypeScript type from that schema, then keep the
post-preview lookup in the newsletter selection flow operating only on the
validated result.
- Line 130: Update the post newsletter lookup flow around postNewsletterMissing
and EmailPreview to expose an explicit pending state while postNewsletterData is
unresolved, and use it to block preview loading and SendTestEmail actions until
the lookup confirms the newsletter exists or is deleted. Add an acceptance case
that clicks Test before the slug lookup resolves and verifies no preview request
or test email is sent.

Learning: Admin UI in Ghost is intentionally not localized. During code review, do not request adding i18n/translation hooks, wrappers, or new locale keys (e.g., updates to `packages/i18n/locales/en/ghost.json`) for Admin UI strings, including any React components under `apps/admin/src/`.

no ref Preview actions must reflect the just-saved post and a current newsletter. Validating API responses and gating cached data behind readiness and error states prevents stale or malformed data from reaching users.

The React editor can show a post's title and body, but there is no way to see how that post will reach readers — the site render, or the newsletter it would be sent as. This adds those components under
apps/admin/src/editor/preview/.They are self-contained: the caller passes the post's id and public preview URL, and the modal reads everything else (settings, tiers, newsletters, the current user, the rendered email) from the Admin API. Nothing wires them into the editor header yet — the header that opens the preview lands with the publish controls — so this ships the surface and its tests on their own.
What's here
post-preview-modal.tsx— a full-screen dialog with Web/Email tabs, a desktop/mobile toggle, the "preview as" audience selector (public visitor, free, paid, a specific tier), copy-preview-link and open-in-new-tab, and close. The Email tab is offered for posts only, when members are on, newsletters are not disabled in editor settings, and the user is not a contributor.onBeforeOpenis awaited before the preview renders, so the caller can persist the draft the preview is about to fetch; the modal itself never writes to the post.browser-preview.tsx— the site render in an iframe, in Shade's desktop or mobile preview chrome.email-preview.tsx+send-test-email.tsx— the rendered email, its subject and sending newsletter, a newsletter switcher when the site has more than one, and a test send to exactly one address (prefilled with the current user's).preview-url.ts— the pure audience-to-URL translation shared by both formats.Notes
srcdociframe sandboxed withoutallow-scriptsand withoutallow-same-origin, so the rendered email can neither run scripts nor reach the admin page. Scrollbar styling is concatenated into that document because the admin stylesheet does not apply inside it.onBeforeOpenstarts during render, so no frame is ever mounted against the pre-save URL; a save that fails is reported and replaced by a retry rather than falling through to a preview of the stale server copy.PostPreviewModalhas no caller yet — the editor header that opens it lands with the publish controls, so nothing in the running app reaches this code.useEmailPreviewanduseSendTestEmailhere should pick it up so a preview never bounces the editor to signin.Testing
