#1038 Add pt/ca/it languages and locale-aware formatting Pull request opened by javuto Add pt/ca/it languages and locale-aware formatting (i18n phase 2) Problem Phase 1 established the i18n infrastructure with en/es/fr/de, but time formatting, chart axes/tooltips, and shared data components were still hardcoded to

en-US

or plain English strings. Change • New languages: Portuguese (pt-BR), Catalan (ca-ES), Italian (it-IT) added to the registry and selector — 7 languages total, each with a full catalog mirroring every English key. • Locale-aware time formatting (

lib/time.ts

): compact units and phrases in `formatRelative`/`formatTimeUntil`/`formatBucketAgo` now translate per language ("in 3d" → "en 3d" / "dans 3j" / "tra 3g"); the >7-day date fallback uses the active locale tag instead of hardcoded

en-US

. • Locale-aware charts (

chart-formatters.ts

): the module-level

en-US

formatter constants became per-language cached functions (

shortDateFmt()

,

weekdayDateFmt()

,

hmsTimeFmt()

,

intFmt()

); all four consumers (x-axis, chart shell, tooltips) updated. • Translated shared components:

Pagination

(empty state, range, prev/next),

SearchInput

(label, placeholder, clear button), and

StatCard

(numbers via

useLocale

formatters). • Fix: switched all catalogs to ICU

{var}

syntax —

i18next-icu

does not interpolate

{{var}}

, so existing placeholders like the user-menu aria label were rendering literally. Performance • Non-English catalogs remain lazy chunks (~1.7–1.8 KB gz each, 6 total); formatter objects are cached per (locale, preset) so charts with thousands of ticks never rebuild

Intl

objects. • Main bundle grew ~0.7 KB gz. Validation •

npm run check

— clean •

npm test

— 355 passed (new: 7-language catalog parity, pt/ca/it matching, translated time strings, locale date formatting) •

npm run build

— all 7 language chunks emitted correctly Follow-ups • Translate feature pages (dashboard, nodes, queries, carves, settings…) • Migrate remaining

toLocaleString()

calls in feature pages to

useLocale

• Optional: backend
