fix: moderation preview scope, comment vote races, and email link origin - #1344
fix: moderation preview scope, comment vote races, and email link origin#1344NiallJoeMaher wants to merge 9 commits into
Conversation
Three fixes, consolidated into one PR by request. 1. Move the moderation preview off the public reader routes (#1340 follow-up) #1340 let admins resolve in_review/rejected posts at their public URLs. That put the public reader — vote, bookmark and comment controls — on a post that may be about to be rejected, and `post.vote` has no status guard, so a misclick writes a vote and author points onto content the moderator is declining. It also stopped admins seeing the site the way readers do, and made the rejected-post banner's "not visible to anyone else" untrue. Preview now lives at /admin/moderation/preview/{id}: read-only, inside the admin gate. The public routes and their visibility filter revert. It also fixes the link path. #1340 sent Preview straight off-site, so the member's own title/excerpt/body — where a spammer would put the payload — was never shown; the preview renders both halves. And that off-site href skipped `safeExternalHref` and rel, so an externalUrl that never passed `httpUrl()` validation would run as a `javascript:` URL inside the authenticated admin session, and the page under review received the admin surface as its referrer. 2. Drop the frozen sort snapshot, serialise votes per comment (#1341 follow-up) Freezing sort scores was more than the fix needed and wrong on its own terms: counts still updated on refetch while the order did not, so a thread could show a 42-point comment below a 3-point one; the documented "re-pick the sort" escape hatch never fired, because selecting the already-selected option is a no-op; and the added tiebreak made Top identical to New on the common all-zero thread. Not refetching after a successful vote is the whole fix. Ordering is derived from the data on screen again, so it cannot contradict the counts beside it. Votes are serialised per comment (newest click wins), since #1341 dropped the in-flight guard without replacing it and overlapping writes could land in either order. The resync remount is per comment too. 3. Email links pointed at the deployment, not the site `getAppOrigin()` fell back to VERCEL_URL, which is the unique per-deployment hostname — and Vercel sets it in production too. With DOMAIN_NAME unset, every link it built (the admin's "post awaiting review" deep link, report emails, the verification link) went out as *.vercel.app. Production now resolves to the project's production domain, falling back to the canonical origin; preview deploys still get their own URL. The duplicate copy of this logic in utils/emailToken.ts is gone.

Review of #1344 found nine issues, three of them mine from the previous round. Draft exposure (the serious one): the new preview route loaded any post by id with no status predicate, so an admin with a post id could read a member's private, never-submitted draft. It is now restricted to work that actually entered the pipeline — published, in_review, rejected — and `postVisibility.ts` is back, minus the admin bypass, carrying tests for both rules including "never exposes a draft, whoever is looking". Deleting that module was never required to drop the bypass, and doing so had also left the same rule inlined twice in two different shapes. Failed votes stranded earlier ones: I removed the pre-remount refetch on the reasoning that the cache never saw the failed vote. That is true of the failed vote but not of earlier successful ones, which never refetch by design — so remounting reseeded the control from a cache that predates them. The refetch is back, before the key bump. Comment ordering on ties was arbitrary: the "Top" comparator leaned on sort stability to keep "the server's order", but the server orders by ltree path, built from a random uuid. On a thread where most scores are 0, that is no order at all. Ties now sort oldest-first, so Top degrades to chronological rather than to a copy of New. Reordering under the reader: with the score snapshot gone, a window-focus refetch could re-rank the thread mid-read. That query no longer refetches on focus; the explicit refetches after create/edit/delete stay, since those follow something the reader did. Also: raw tRPC error text could reach the vote toast (only the rate-limit message, which is written for readers, is surfaced now); a malformed post id 500'd on the uuid cast instead of 404ing; the preview's two queries ran serially when both key off the route param; and a fork deploying to production without VERCEL_PROJECT_PRODUCTION_URL got codu.co hardcoded over its own configured NEXTAUTH_URL.

The suite has been failing on CI while staying green locally: 19 failures spread across admin navigation, the editor publish flow, bookmarking, the feed sidebar and moderation. Identical failures on develop and on every branch off it, so nothing in the feature work caused them. They all share a cause. Playwright's webServer ran `next dev`, so the first request to each route blocked on an on-demand Turbopack compile. Locally that is under a second; on a cold runner with three workers compiling at once it outlasts the 10s expect timeout — hence assertions like `toHaveURL(/admin/users)` polling 13 times and giving up while the navigation was still compiling. CI now builds once and serves it. Measured on the same machine, a cold route costs ~0.7-1.2s under `next dev` and ~0.02-0.03s prebuilt. Local runs keep `next dev` for the fast feedback loop. EMAIL_AUTH_ENABLED is set for the job because a production build runs with NODE_ENV=production, which would otherwise disable the passwordless provider that dev turns on implicitly.

Tiptap v2 generateHTML JSONContent unknown node type invalid document structure throws Node.fromJSON
💡 Result:
In Tiptap v2, the generateHTML function generates HTML from JSONContent by using Node.fromJSON under the hood [1][2]. Because Node.fromJSON is a strict ProseMirror method, it throws a RangeError: Unknown node type when it encounters a node type in your JSON that is not defined in the extensions list provided to generateHTML [3][4][5]. Currently, there is no direct way to pass a fallback handler to generateHTML to ignore or gracefully handle these unknown nodes [4][5]. The function will crash whenever it hits an undefined node type [3][4]. To address this issue, you have a few options: 1. Ensure all extensions are present: You must include every extension that defines a node type present in your JSON content within the array passed to generateHTML [3]. If you have removed an extension that was previously used to generate that JSON, you will need to either re-add it or implement a minimal dummy extension that defines the missing node type so that Node.fromJSON can successfully parse the document [4][5]. 2. Use the Static Renderer (if applicable): If you are using Tiptap's Static Renderer package, it provides more advanced options including unhandledNode and unhandledMark handlers [6][7]. While these are designed to provide fallbacks for rendering, be aware that there are known reports indicating that these handlers may not always prevent crashes if the initial node creation via Node.fromJSON still triggers a validation error [8][7]. 3. Validate or Sanitize JSON: If you frequently deal with unknown or legacy node types, you may need to write a pre-processing function to traverse your JSONContent and remove or sanitize nodes that do not correspond to your current schema before passing the JSON to generateHTML [5]. Tiptap does provide mechanisms like enableContentCheck and onContentError to help detect schema mismatches, but these are generally for the editor instance and do not automatically resolve the rigid behavior of Node.fromJSON during HTML generation [9][10][11].

Strip paths from configured origins.
toOrigin removes only the scheme and trailing slashes. If DOMAIN_NAME contains /api/auth, this function returns a URL with that path. Verification links then append /verify-email to the path. Return URL.origin instead.
Proposed fix

- return `https://${domain.replace(/^https?:\/\//, "").replace(/\/+$/, "")}`;
+ return new URL(`https://${domain.replace(/^https?:\/\//, "")}`).origin;

The e2e harness fix in the previous commit did not take. The job is triggered by `pull_request_target`, which takes the WORKFLOW from the base branch and the CODE from the PR head — so the build step added to the workflow never ran, while playwright.config (from the head) had already switched to serving a prebuilt app. Result: "Could not find a production build". The build now happens inside the webServer command, where head and workflow cannot disagree, and the env it needs moved into the npm scripts for the same reason. Review fixes: - moderationPreviewFilter missed `scheduled` and `unlisted`, so preview 404'd on a post the admin had just approved-with-schedule. The status list is now derived from the enum instead of hand-listed. - The "top" tie-break went back to newest-first. Oldest-first read better as conversation order but buried a comment the moment you posted it, which is worse than Top resembling New on an unvoted thread. - create/edit awaited react-query's void `mutate`, so their try/catch was dead and the editor cleared before the request finished: a failed post discarded what you typed, silently. Both use mutateAsync now. - The preview fetched the cover image and never rendered it. Clean body copy under an abusive image would have sailed through; it is shown now, behind the same scheme guard as the external URL. - PostBody rendered the site-wide 404 component for an empty tiptap body, which put a "page not found" panel inside the admin shell. The empty state is the caller's to choose now. - getAppOrigin fell back to the hardcoded codu.co ahead of the deployment's own URL, so an unconfigured fork mailed its users to this site. - A failed vote now clears its queued follow-up explicitly. Accepted, not fixed: the thread no longer refetches on window focus, so an open tab does not pick up other people's comments until you post, navigate or reload. That is the cost of not moving comments under someone mid-read.

Provide alternative text for the cover image.
alt="" marks the image as decorative, but the surrounding comment states that moderators must review the cover image before approval. Screen-reader users will not receive any information about this required content. Use stored image alternative text, or at least expose a non-empty label until that metadata is available.

The prebuilt server ran, but every authenticated test failed: NextAuth rejects the request host under NODE_ENV=production unless AUTH_TRUST_HOST is set, so /api/auth/session returned UntrustedHost, session.user was undefined, and pages blew up on `session.user.username`. 159 failures. Dev never hits this — it trusts the host implicitly — which is why the suite passed locally. My earlier local check passed for the wrong reason: I had happened to pass AUTH_URL on the command line, which also satisfies the trust check, so the gap only showed up on CI where it is not set. Reproduced locally against a production build: without AUTH_TRUST_HOST, /admin redirects and the log carries UntrustedHost; with it, /admin and /admin/moderation both return 200 and the log is clean.

`setup.ts` and `teardown.ts` hardcoded localhost:5432/postgres, which is also the dev database. Running the suite locally therefore writes fixtures into whatever you have been working on, so the remaining pre-existing failures cannot be debugged without risking your own data. Both now honour DATABASE_URL, falling back to the same string, so CI is unaffected and a local run can be aimed at a scratch database instead.

Guard the shared DATABASE_URL contract in both lifecycle hooks.
Both hooks accept arbitrary non-null values while one seeds data and the other deletes data. Add one shared validation rule that rejects empty values and accepts only an explicitly disposable E2E database.

…e DB url Three causes behind the long-standing failures, found by running the suite locally against a throwaway database. MODERATION_ENABLED was never set for the e2e app. The whole pipeline — publish gating, the review queue, link dedupe — is behind that flag, so e2e/moderation.spec.ts was asserting behaviour the server had switched off. All four of its tests pass with the flag on. The feed sidebar test asserted the right rail is visible on any non-mobile viewport, but .app-main folds the rail away under 1300px and Playwright's desktop viewport is 1280 — so it was asserting against a width where the rail is correctly hidden. The test now widens past the breakpoint. Four helpers in e2e/utils/utils.ts still hardcoded the connection string that the file had already centralised, so a run aimed at a scratch DATABASE_URL wrote its fixtures into the default database instead and then failed on foreign keys. Local suite on Desktop Chrome: 129 passed, 1 failed (a flaky multi-user notification test), down from 6 failures before these changes.

Bookmarks are per-user and all four browser projects run as the same e2e user, so a shared article made the bookmark specs race each other: one project saved it while another was asserting it was still unsaved. That is why they failed on Firefox and mobile but never on Desktop Chrome, which happened to get there first. saved.spec.ts already ran serially, but serial mode only orders tests within a project, not across them. Each project now creates and cleans up its own article. Reproduced the failure locally across all four projects, and all 52 tests in those two files pass afterwards. The /saved assertion no longer needs its "or the empty state" escape hatch either, since nothing else can unbookmark it. Also gives the discussion editor's submit button a data-testid. "Reply" is the label of both the editor's submit button and every comment's expand-reply button, so the notification spec was picking it out with .last() — ambiguous as soon as a comment has nested children. That spec still fails intermittently for a separate reason (its reply lands as a top-level comment, so the server correctly raises "commented on your post" rather than "replied to your comment"); it retries green and is left for a follow-up rather than papered over here.

The routeless-/[id] guard took the FIRST anchor inside a content card, but
that is the author handle ("/{username}") — a real page that nonetheless
reads as a bare single-segment path to the shape check, so the test failed
with 'href "/e2e-test-user-one-111" looks like a routeless /[id] page'. It
only surfaced on some browsers because which card ranks first varies, and a
source card's handle link ("/s/{slug}") has two segments and slips through.
The card's content link now carries data-testid="content-card-link" and the
test targets that, so it checks the link the guard is actually about.
All 44 tests in the file pass across all four browser projects.

Consolidates #1342 and #1343 into one PR (as requested) and adds a third fix: emails were linking to
*.vercel.appinstead of codu.co.#1340 and #1341 merged before a second review pass ran on them. That pass found the approach in each was wrong, not just the details — so most of this diff is deleting what those two added.
1. Email links pointed at the deployment, not the site
getAppOrigin()fell back toVERCEL_URL. That is the unique per-deployment hostname (codu-a1b2c3.vercel.app), and Vercel sets it in production too — so withDOMAIN_NAMEunset, every link it built went out pointing at the deployment:/admin/moderation?item=…)Production now resolves to the project's production domain (
VERCEL_PROJECT_PRODUCTION_URL), falling back to the canonicalSITE_ORIGIN. Preview deploys still get their own URL, which is what you want there.DOMAIN_NAMEstill overrides everywhere.utils/emailToken.tshad a second, independent copy of the same buggy precedence; it now calls the shared helper. 5 new unit tests cover the production/preview split.2. Moderation preview moved off the public reader routes
#1340 let admins resolve
in_review/rejectedposts at their public URLs, which:post.votehas no status guard, so one misclick writes a vote and author reputation points onto content being declined;Preview now lives at
/admin/moderation/preview/{id}: read-only, no engagement controls, inside the existing admin gate. Public routes and their visibility filter revert to what they were.This also fixes the link path, which #1340 got backwards twice:
gatePublishroutes links into review on spam signals, so this was the case the feature existed for. The preview now renders both halves.safeExternalHrefandrel, so anexternalUrlthat never passedhttpUrl()validation would execute as ajavascript:URL inside the authenticated admin session, and the page under review receivedcodu.co/admin/moderationas its referrer.Body rendering is extracted to a shared
PostBodyused by both the preview and the public reader, so they cannot drift.3. Comment votes: frozen sort snapshot dropped, votes serialised
#1341's score-freezing was more than the fix needed and wrong on its own terms:
Not refetching after a successful vote is the whole fix: the new count lives in
VoteControl,discussionsis untouched, nothing re-ranks under the reader. Ordering is derived from the data on screen again, so it can never contradict the counts beside it.Votes are now serialised per comment (newest click replaces any queued one) — #1341 removed the in-flight guard without replacing it, so overlapping writes could land in either order and leave the stored vote disagreeing with the UI. The resync remount is per comment too, so one failure no longer discards other comments' optimistic state.
Verified locally
getAppOrigin, including production-never-uses-VERCEL_URLand preview-still-does.in_reviewURL → 404 again (both/{username}/{slug}and/d/{slug}); published posts still 200; preview renders for article, question and link posts, with the link preview showing the member's body and the guarded destination.npm run lint,npm run prettier,npm run test:unit(123 passing),npm run build.
