ref https://linear.app/ghost/issue/GVA-921/1-click-export-uxui Self-hosters have no way to take everything out of Ghost in one go: today a full export means clicking through five separate downloads (content JSON, members CSV, post analytics CSV, per-theme zips, routes/redirects files) and knowing they all exist. The one-click export plan gives everyone a single "Export data" flow; this adds the delivery mode that works on every install with no host infrastructure: GET /ghost/api/admin/exports/download/ streams one zip composed from the same services the individual export endpoints already call. - The orchestrator (services/exports) appends each selected component to an archiver STORE stream that pipes straight to the response, so memory stays flat and the download starts immediately. No HTTP self-calls and no background jobs — in-process service calls only. - A component that fails before its data is acquired is skipped and recorded in export-report.json rather than failing the request: once headers are sent a mid-stream HTTP error is impossible, and a bundle missing one piece beats a broken download. - `media` is rejected by validation. Media is exactly the component that forces background jobs and email delivery, so it is reserved for the host-webhook mode (not part of this change). - The endpoint reuses the db.exportContent permission (Owner/Admin only) instead of minting a new permission: a site export contains everything a database export contains, so the same gate applies and no migration is needed while the feature is behind a labs flag. - export.json matches the /db/ download byte-for-byte and themes are nested per-theme zips, so every artifact in the bundle restores through the existing import surfaces. - The members CSV transform moves out of the members output serializer into its own module (mirroring posts-csv-transform) so the orchestrator can reuse it without duplicating the CSV logic. The download e2e tests drive a real HTTP server rather than the in-process agent: the zip streams with backpressure, and the test agent's mock socket never signals drain, deadlocking any response body larger than the write buffer.
ref https://linear.app/ghost/issue/GVA-921/1-click-export-uxui The sync branch of the "Export data" dialog was a static mockup: a timer pretended to prepare an export and downloaded an empty zip. It now requests /exports/download/ with the selected components as a plain navigation, so the browser's download manager streams the zip to disk — a large export never sits in tab memory, which is why the navigation approach was chosen over the fetch-into-blob helper. The dialog can't observe a navigation download finishing, so the fake "done" state is gone; the confirmation tells the user the download has started and can be watched in the browser. The async (host-webhook) branch of the dialog stays mocked — its backend is a separate piece of work.
ref https://linear.app/ghost/issue/GVA-921/1-click-export-uxui A critical review of the sync export surfaced two silent-data-loss bugs, a hang, and several robustness and duplication issues: - The analytics CSV silently contained only 15 posts: the posts exporter falls back to its default page cap when no limit is given. Both CSV exports now pass `limit: 'all'` — the same call the standalone endpoints make — which also keeps the members exporter on its streaming path instead of materialising every member id into a WHERE IN. The download e2e test now seeds more posts than the default cap so a regression cannot pass unnoticed. - A CSV source erroring mid-stream (e.g. a dropped DB connection) hung the response forever: archiver wraps sources with `.pipe()`, which never propagates errors. Streaming entries now tie their lifecycle to the archive in both directions — a source error destroys the archive (failing the download instead of hanging), and a destroyed archive (client hung up) destroys the sources, so a paused row stream releases its DB connection instead of holding it for the client's whole download. - A repeated `components` query param (an array after qs parsing) crashed query() with a 500, and an explicitly empty `components=` exported everything. The param is now normalized in an input serializer; empty selections are rejected with a 422. - The zip now uses deflate (the JSON/CSV entries compress 5-10x) with per-entry STORE only for the nested theme zips, and theme zips are staged as temp files streamed off disk rather than buffered — many large themes no longer multiply resident memory. Theme zipping moved into ThemeStorage so the export and the theme download endpoint can't drift apart, and theme names are validated against the theme list on the way. - The streaming CSVs are appended before the buffered content JSON so their DB connections drain first, and export-report.json entries carry a status object (`ok`/`partial`/`failed` plus the skipped names) so a partially-exported themes component no longer reads as wholesale failure. - Admin now feature-detects the endpoint via a config capability signal (`exports.download`) instead of trusting the labs flag alone — Admin and core deploy independently, and a labs flag can be forced on an older core via config or remote overrides. With the signal absent the legacy export buttons stay. The dialog's download call moved into admin-x-framework's api layer with the other download helpers, and the post-download dialog state shows a spinner instead of a premature success check. - The zip and CSV stream responses share one helper now instead of two near-verbatim copies, and SiteExporter's failure paths are unit tested (skip-and-report, partial themes, mid-stream teardown, client-abort cleanup).
The config output serializer picks an explicit key allowlist, so the `exports` capability signal added to the public-config service was silently stripped from the /config/ response — Admin's deploy-skew gate read it as absent and kept the legacy export buttons even on a core that serves the endpoint. Caught by clicking through the flow against a real Ghost instance; the admin acceptance tests use a fake config response, which is exactly why the pick list slipped past them.
The report added bookkeeping to every export to describe the rare failed one, and its promise was shaky anyway: a component that fails mid-stream tears the whole download down rather than being recorded, so the report could only ever describe acquisition-time failures. Server-side logging already covers diagnosing those. A failed component is now simply absent from the bundle.
The archive's close handler runs its registered cleanups the moment the client hangs up — a theme zip still being staged at that point registered its cleanup too late and leaked its temp dir, and staging kept going against a dead archive. The exporter now stops staging once the archive is destroyed and removes a late-finishing theme zip immediately; the same guard covers a CSV stream acquired after the archive closed, which would otherwise keep its DB connection. Also swapped the fixed sleeps in the exporter unit tests for event and condition waits, so a slow CI machine can't assert mid-append.
The download was a plain iframe navigation, which a page cannot observe: the "Preparing your export…" state stayed on screen forever, even after the zip had landed — and a failed request was equally invisible. The dialog now downloads through the fetch-based blob helper, so it reaches a real "Export downloaded" state, surfaces errors (returning to the selection for a retry), and Cancel actually aborts the request. Browsers back large blobs with disk, so the zip does not have to fit in tab memory — which was the original reason for choosing the navigation approach.
Extracting the shared stream-response helper genericized the guard message to "Missing export filename", but the posts CSV serializer unit test pins the original "Missing CSV export filename" — and the CSV endpoints should behave exactly as before the refactor. The message is now a per-format parameter on the shared helper.
Trimmed every comment that narrated what the code already says and kept only the constraints the code cannot show: archiver's .pipe() error swallowing, the close-during-staging races, why the CSVs pass limit 'all', and the deploy-skew capability signal. Also asserted the error toast in the failed-download acceptance test, so the error path is verified end to end rather than only by the retry state.
The name-validation branch of the themes storage zipToFile was only reachable through the site export e2e flow, whose coverage codecov does not see.
The sync export is staying behind the selfServeArchives labs flag, so the flag is the whole gate: a config capability signal for deploy skew adds a moving part the feature doesn't need at this stage. If the flag ever graduates while Admin and core still deploy independently, feature detection can come back with the GA work.
The export's whole point is that every artifact restores through an existing import surface, so the e2e suite now proves it: the downloaded zip's export.json goes back through the universal importer, members.csv through the members importer, a theme zip through the theme upload, and routes.yaml/redirects.yaml through their uploads — all against the real endpoints. A format drift in any of the five artifacts now fails CI instead of surfacing as a broken restore.
The ambient module declaration types every archiver import in ghost/core, not just the site exporter's, but its comment read as if it were local to one service. It now says so and points the next caller at extending it here, instead of leaving them to hunt down why tsc rejects parts of the real archiver API.

ref GVA-917
ref Self-serve archives
Implements the sync delivery mode of the one-click data export, building on
the mockup that landed in #29915. With the
selfServeArchivesflag on, "Export data" now really downloads a full sitearchive:
GET /ghost/api/admin/exports/download/streams one zip composed ofcontent JSON, members CSV, post analytics CSV, per-theme zips, and
routes/redirects — everything except media, which stays reserved for the host
(async) mode that isn't part of this PR (its dialog branch remains mocked).
How the zip is composed
The orchestrator calls the same services the five standalone export endpoints
call — no HTTP self-calls, no background jobs, no duplicated controller logic:
flowchart LR UI["Export data dialog"] -- "GET /exports/download/?components=…" --> C["exports controller"] C --> SE["SiteExporter (services/exports)"] SE -- "doExport()" --> J["export.json"] SE -- "membersService.export({limit:'all'})" --> M["members.csv"] SE -- "postsService.export({limit:'all'})" --> A["post-analytics.csv"] SE -- "themeStorage.zipToFile()" --> T["themes/{name}.zip"] SE -- "routeSettings / customRedirects" --> R["routes.yaml + redirects.yaml"] J & M & A & T & R --> Z["archiver zip → streamed response"]Decisions worth reviewing:
memory stays flat and the download starts immediately. The price is failure
semantics: once headers are sent, a component that fails to acquire can only
be skipped (it's logged server-side and simply absent from the bundle). A
mid-stream failure of a CSV source deliberately destroys the archive — a
visibly broken download beats a silently incomplete one — and stream
lifecycles are tied together in both directions so a dropped DB connection
can't hang the response and a client disconnect can't pin a DB connection.
export.jsonis byte-identical to the/db/download and themes are the exact zips the theme upload accepts, so every
piece of the bundle restores through existing import surfaces.
db.exportContent(Owner/Administrator only) instead ofminting a new permission + migration: a site export contains everything a
database export contains, so the same gate applies — and it's a superset of

page, which left the dialog stuck on "Preparing your export…" forever and
swallowed errors. The blob approach gives the dialog a real "Export
