translations

objectAdvancedserverbrowserlive demo

Downloads Salla's shared translations file, every storefront message in Arabic and English, which the engine's translate function reads.

import { translations } from '@salla.sa/twilight-theme-engine/api/translations';

In plain words

Labels such as "Add to cart" are not written in your theme: Salla keeps them in one shared file, with every message in each language. translations.get() downloads that file.

The engine does this before every page and builds the translate function t from it, which is what components should use (useTranslation().t('pages.cart.total')). Read the file yourself only to inspect or search it.

Signature

translations.get(): Promise<TranslationMessages | null>   // GET https://cdn.salla.network/js/translations.json
translations.queries.byLocale()                            // key ['translations']: takes no locale

type TranslationMessages = Record<string, Record<string, string>>;
// real shape: { 'ar.trans': { common: {…}, pages: {…}, … }, 'en.trans': {…} }

Try it live

Salla's shared translations file, already in the cache: one file with every language, looked up by a dotted key.Try this: try pages.cart.total, then shorten it to pages.cart to reach a group instead of a message.

What a theme writes

import { useTranslation } from '@salla.sa/twilight-theme-engine/i18n';

// In a component, prefer t(): it reads this same file for the page's language.
export function AddToCartLabel() {
  const { t } = useTranslation();
  return <span>{t('pages.cart.add_to_cart')}</span>;
}

Example

app/dev/CartMessages.tsx

import { useQuery } from '@tanstack/react-query';
import { translations } from '@salla.sa/twilight-theme-engine/api/translations';
import { useTranslation } from '@salla.sa/twilight-theme-engine/i18n';

/** Development helper: the cart messages Salla provides for this page's language. */
export function CartMessages() {
  const { locale } = useTranslation();
  const { data } = useQuery(translations.queries.byLocale());
  // Typed as flat strings, but each file is nested: pages → cart → total.
  const file = data?.[locale + '.trans'] as unknown as
    | { pages?: { cart?: Record<string, string> } }
    | undefined;

  return (
    <dl>
      {Object.entries(file?.pages?.cart ?? {}).map(([key, text]) => (
        <div key={key}>
          <dt>pages.cart.{key}</dt>
          <dd>{text}</dd>
        </div>
      ))}
    </dl>
  );
}

How it behaves

Fetched through the cdn client, so no store or customer headers are sent: the file is the same for every store. Timeout 5 s. About 150 KB with only ar.trans and en.trans in it (2026-09-16).
It never throws: a failed download logs a warning and returns null, and t is then built with no Salla messages, so a key renders as itself (or as the fallback you pass).
rootBeforeLoad awaits ensureQueryData(translations.queries.byLocale()) on every navigation and passes the file to createI18nInstance(locale, …), which takes <locale>.trans as the default namespace and falls back to the theme's own bundled translations.
Because the file sits in the query cache after the server render, it travels to the browser with the page HTML.

Gotchas

TranslationMessages promises string values one level down, but the files are nested (pages → cart → total). data['ar.trans']['pages.cart.total'] finds nothing: walk the dotted key, or use t().
Despite its name, byLocale() takes no locale and its key is only ['translations']: one file holds every language.
docs/11-internationalization.md shows translationsQueries.byLocale(locale), a store-specific CDN address and a keys factory. None of that exists: the export is translations, and it reads one shared file.

cdn

A bare ky client for Salla's public CDN at cdn.salla.network; it sends no store, language or customer headers.

store

Loads the store, its theme, languages and currencies in one call: the same call the root loader makes before every page.
