Description

English text reached the UI in every language. It came from option tables in exported constants, which the hardcoded-string checker never read. The checker ran its object-property check only on .tsx/.jsx files, and it did not know reason. So a label: in a .ts module was invisible to it.

This PR widens that one check to .ts files, adds reason, and fixes everything the wider check finds. check:i18n passes on the result.

What was rendering English, and the fix

Where Fix New keys Reused keys
a Query builder: fields.UPLOADED_OVER_SIZE, fields.HARDLINK_SCOPE_CROSS, torrentStates.tracker_error were missing in all 11 locales, English included. The English defaultValue hid the gap. Added the keys. constants.test.ts now checks that every key a getTranslated* helper asks for exists in en. 3 —
b Workflow dialog: "Not supported for simple sorting" / "…score multipliers" tooltips t() in WorkflowDialog.tsx 2 —
c Torrent sort menus (mobile cards and compact view): 36 labels labelKey in torrentSortOptions.ts 7 (sort.options.*) 26 tableColumns.*, 3 detailsPanel.labels.*
d Column filter operations ("Equal to", "Contains", "Before", …): 19 labels labelKey in column-constants.ts 18 (columnFilter.operations.*) —
e Torrent creator: "Auto (recommended)" piece size The dialog renders the Auto item itself. — creatorDialog.pieceSizePlaceholder
f PWA update toasts (title, descriptions, "Reload") i18n.t in pwa.ts 4 (pwaUpdate.*) updateBanner.updateAvailable
g Demo build sidebar links: "Back to getqui.com", "Docs" labelKey in lib/demo.ts 2 (nav.backToSite, nav.docs) —
h API errors: "(server returned HTML error page)" One key with a {{message}} placeholder, so each language orders it its own way 1 (apiErrors.htmlErrorPage) —

Total: 37 new English strings, and 370 values across the 10 other locales.

Visible English changes:

  • The PWA "Update available" toast title now reads "Update Available", because it reuses the update banner's key.
  • FALLBACK_THEME no longer has a description; it is deleted, not translated. That text showed only until GET /api/themes answered. The real theme descriptions come from the @description: headers in internal/themes/assets/*.css, always in English. Translating only the fallback would show a translated line and then switch it to English once the list loads. The card already hides an empty description. Translating theme descriptions properly is tracked separately.

Also removed: the unused DURATION_UNITS and SPEED_UNITS arrays in query-builder/constants.ts. The wider check flagged DURATION_UNITS's "seconds"/"minutes" labels; SPEED_UNITS is its twin, whose "B/s" labels the checker treats as units. Both arrived with the file in #818 and neither was ever imported: the live copies are local to ColumnFilterPopover.tsx.

Checker change

  • find-hardcoded-i18n-literals.mjs runs the object-property check on .ts files and adds reason. The variable and format-return checks stay at .tsx, which keeps out false positives such as "0 B/s". The skip lives in that check, not in shouldScanFile: walkFiles is shared with find-unused-i18n-keys.mjs, and skipping the file there would orphan the ~150 keys these tables keep alive (measured: 105 unreachable keys become 131, and that check fails).
  • It exempts src/components/query-builder/constants.ts. Every table there renders only through a getTranslated* helper, or getFieldLabel and its siblings, with the English as defaultValue. A comment at the top of that file names the coupling. constants.test.ts finds every exported getTranslated* helper on its own. It fails if it finds fewer than 5, and it fails if any key a helper asks for is missing in en.
  • Why a file exemption and not a list of table names: a list has to name every table, so each new fallback table added to this file would fail the check until someone edited the list. The exemption belongs to the file's convention, not to today's tables.

Translations are best effort

The guaranteed part is mechanical. No raw keys, no English, and no missing keys in any locale; check:i18n passes in full. The wording of the new values is model-written and open to correction by native speakers.

  • Where a locale already had wording for the same term, I reused it: operator words from queryBuilder.operators, session and limit labels from queryBuilder.fields, and "cross-instance" from statusBar.streamStatus.crossInstance.
  • I checked each value against its English source for meaning, placeholders and punctuation. Chinese uses full-width parentheses.
  • Least sure:
    • the date operations columnFilter.operations.on, after and before, especially ko and uk;
    • uk sort.options.lastSeenComplete;
    • de "Doku" and fr "Docs" for nav.docs;
    • cs sort.options.lastSeenComplete, which reuses the column's "Naposledy dokončeno".

How has this been tested?

In German, on the demo build (pnpm build:demo + vite preview), text read from the DOM. On the pushed head c966487:

  • all 7 column-filter operations on the size column;
  • the sort menu, all 36 options.

Earlier, on the same code at e9bfa9d:

  • the compact-view sort menu, all 36 options;
  • the demo sidebar links.

No English and no raw keys.

On the real binary at e9bfa9d (go build, its own bundle, auth disabled, an unreachable instance):

  • the workflow dialog's simple-sort field list shows the tooltip "Nicht unterstützt für einfache Sortierung";
  • it lists "Hochgeladen / Größe" and "Hardlink-Bereich (instanzübergreifend)", two of the keys added in (a).

Not tested live:

  • the creator dialog's Auto item, which needs a connected qBittorrent;
  • the PWA toasts, which need a service-worker update;
  • the HTML-error message, which api.export.test.ts covers.

Performance

Affected paths: the sort menus call t() per option, the column filter calls it per operation, and the workflow dialog builds its disabled-field lists in a useMemo keyed on t. Bundle: new locale keys, and api.ts/pwa.ts now use i18next.

Measured at the merge-base 110b128 vs c966487, with pnpm build in a node:24 container:

base PR Δ
JS files on first load (index.html) 7 7 0
First-load JS, raw 3,122,165 B 3,124,749 B +2,584 (+0.08%)
First-load JS, gzip -9 800,915 B 801,567 B +652 (+0.08%)
All JS chunks, all locales, raw 6,376,289 B 6,392,730 B +16,441
All JS chunks, gzip -9 1,779,502 B 1,785,158 B +5,656

The file count matters. My first version imported @/i18n from api.ts, and that split the bundled English namespaces out of the entry chunk: first load went from 7 to 15 JS files. api.ts now imports the i18next singleton that @/i18n initializes, and the count is back to 7. Before initialization, that singleton returns undefined, even when given a defaultValue. So api.ts keeps an explicit English fallback. api.export.test.ts, which never imports @/i18n, covers that path; it fails without the fallback. api.html-error-i18n.test.ts covers the translated path in German.

t() cost: German, i18next with the real torrents bundle. The 37 lookups for a full sort-menu render took 120–122 µs per render over 5 runs of 20,000 renders each. That is about 3.3 µs per lookup, on node 24 in the podman VM on an Apple Silicon Mac. The menus render their items only while open, and the trigger label is one lookup. Conclusion: no measurable regression.

Checklist

  • My PR title follows the Conventional Commits format (it becomes the squashed commit message)
  • If this changes the database schema, I have added migrations for both SQLite and PostgreSQL (no schema change)
  • I completed the mandatory performance checks and recorded the outcome in Performance

AI disclosure

Yes. Claude Code (Claude Opus 5) wrote nearly all of the code, the tests and the translations, and ran the measurements. Colin Hebert directed the work and reviewed it.

Summary by CodeRabbit

  • New Features
    • Added a selectable Auto piece-size option in the torrent creator.
    • Added localized labels for torrent sorting, column filters, demo navigation, workflow priority guidance, and automation fields across supported languages.
    • Added translated messages for app updates and HTML API errors.
  • Bug Fixes
    • HTML API errors now display a localized message when translations are available.

Sort options, column filter operations, the Auto piece size, workflow
sort/score disabled reasons, PWA update toasts and demo links rendered
English literals from exported objects. Three query-builder keys were
also missing in every locale, hidden by their English defaultValue;
constants.test.ts now checks every helper lookup has an en key.
The object-property check only ran on .tsx/.jsx files and never looked
at reason, so labels in exported .ts constants were invisible. The
query-builder fallback tables are exempt; constants.test.ts covers them.
Importing @/i18n from api.ts split the eager English namespaces out of
the entry chunk: 7 -> 15 JS files on first load. api.ts now uses the
i18next singleton that @/i18n initializes.
The description showed only until GET /api/themes answered, whose
descriptions come from the theme CSS headers in English. Translating
just the fallback would flip from translated to English on load.
A named table list failed each new fallback table, such as the
content-type list in #2757. The key test now finds every getTranslated*
helper itself and fails if it finds fewer than today's five.
The bare i18next singleton returns undefined, even with a defaultValue,
until @/i18n initialises it. api.export.test.ts no longer imports
@/i18n, so it covers that path; a new test covers the translated one.

Walkthrough

UI labels and messages now use translation keys across navigation, workflow settings, torrent controls, PWA updates, and HTML API errors. Locale catalogs add corresponding translations. The hardcoded-literal scanner and query-builder tests now cover TypeScript properties and translation-key coverage.

Changes

Internationalized UI behavior

Layer / File(s) Summary
Translated UI labels and messages
web/src/components/instances/preferences/WorkflowDialog.tsx, web/src/components/layout/*, web/src/components/torrents/*, web/src/hooks/torrent-table/*, web/src/lib/*, web/src/pwa.ts, web/src/utils/themeLoader.ts
Workflow reasons, demo links, torrent sort and filter labels, PWA messages, and HTML API errors use translations. The Auto piece-size option is selectable. HTML API errors retain a fallback message when a translation is unavailable. The fallback theme description was removed.
Translation catalog entries
web/src/i18n/locales/*
Locale catalogs add translations for automation fields and states, navigation, workflow reasons, PWA messages, HTML API errors, torrent filter operations, and sort options.
Literal scanner and translation-key checks
web/scripts/find-hardcoded-i18n-literals.*, web/src/components/query-builder/*, web/AGENTS.md
The scanner checks .ts properties and exempts the query-builder constants file. Tests cover scanner behavior and query-builder translation-key coverage. The exported SPEED_UNITS constant was removed.

Comment thread web/src/i18n/locales/de/torrents.json
The key test dispatched on parameter count; it now dispatches on the
helper's name, so a future per-field helper throws instead of being
skipped. api.ts drops a cast the types do not need. The constants.ts
comment says what a new table must provide, and web/AGENTS.md says the
rule covers option tables in .ts modules, which the checker now reads.
It said the same thing twice and named the checker CI already runs.
