Alle UI-Strings werden über `public/i18n.js` verwaltet. Kein hardcodierter Text in JS-Dateien außer in Locale-Dateien. All UI strings are managed via `public/i18n.js`. No hardcoded text in JS files outside of locale files.
### Architektur ### Architecture
- **Modul:** `public/i18n.js` — exports: `initI18n()`, `setLocale()`, `t(key, params?)`, `getLocale()`, `getSupportedLocales()`, `formatDate(date)`, `formatTime(date)` - **Module:** `public/i18n.js` — exports: `initI18n()`, `setLocale()`, `t(key, params?)`, `getLocale()`, `getSupportedLocales()`, `formatDate(date)`, `formatTime(date)`
- **Locale-Dateien:** `public/locales/de.json` (Referenz), `public/locales/en.json` — Struktur: `{ "modul.camelCaseKey": "Wert" }` - **Locale files:** `public/locales/de.json` (reference), `public/locales/en.json` — structure: `{ "module.camelCaseKey": "Value" }`
- **Variablen:** `{{variable}}`-Syntax in Übersetzungsstrings, z.B. `t('tasks.assignedTo', { name: 'Anna' })` - **Variables:** `{{variable}}` syntax in translation strings, e.g. `t('tasks.assignedTo', { name: 'Anna' })`
- **Fallback-Kette:** aktive Locale → Deutsch (`de`) → Key selbst - **Fallback chain:** active locale → German (`de`) → key itself
- **Datumsformat:** `Intl.DateTimeFormat` mit aktuellem Locale — `formatDate()` und `formatTime()` aus `i18n.js` - **Date format:** `Intl.DateTimeFormat` with current locale — use `formatDate()` and `formatTime()` from `i18n.js`
### Sprach-Erkennung ### Language Detection
1. `localStorage` Eintrag `oikos-locale` (manuelle Auswahl) 1. `localStorage` entry `oikos-locale` (manual selection)
2. `navigator.languages[0]` (Browser-Sprache) 2. `navigator.languages[0]` (browser language)
3. Fallback: `de` 3. Fallback: `de`
### Neue Sprache hinzufügen ### Adding a New Language
1. `public/locales/xx.json` erstellen (Kopie von `de.json`, übersetzen) 1. Create `public/locales/xx.json` (copy of `de.json`, translate)
2. `SUPPORTED_LOCALES` in `public/i18n.js` um `'xx'` erweitern 2. Add `'xx'` to `SUPPORTED_LOCALES` in `public/i18n.js`
3. Label in `oikos-locale-picker` ergänzen (`LOCALE_LABELS['xx'] = 'Name'`) 3. Add label in `oikos-locale-picker` (`LOCALE_LABELS['xx'] = 'Name'`)
### Locale-Wechsel ### Locale Switching
`setLocale(locale)` speichert die Auswahl, lädt die neue Locale-Datei und feuert das `locale-changed` Custom Event. Alle Seiten-Module und Web Components hören dieses Event und rendern sich neu — kein Seiten-Reload nötig. `setLocale(locale)` saves the selection, loads the new locale file, and fires the `locale-changed` custom event. All page modules and web components listen to this event and re-render — no page reload required.
