# Directus Integration - Migration Guide
-## 🎯 Was wurde geändert?
+## 🎯 Overview
-Das Portfolio nutzt jetzt **Directus als CMS** für alle Texte. Die Integration ist **hybrid**:
-- ✅ **Directus** (primär) → Texte werden aus Directus CMS geladen
-- ✅ **JSON Fallback** (sekundär) → Falls Directus nicht erreichbar, nutzen wir messages/*.json
+This portfolio now has a **hybrid i18n system**:
+- ✅ **JSON Files** (Primary) → All translations work from `messages/*.json` files
+- ✅ **Directus CMS** (Optional) → Can override translations dynamically without rebuilds
-## 📁 Neue Dateien
+**Important**: Directus is **optional**. The app works perfectly fine without it using JSON fallbacks.
+
+## 📁 New File Structure
### Core Infrastructure
-- `lib/directus.ts` - REST Client für Directus (nutzt `de-DE`, `en-US`)
-- `lib/i18n-loader.ts` - Lädt Texte mit Fallback-Chain
-- `lib/translations-loader.ts` - Batch-Loader für alle Sections
-- `types/translations.ts` - TypeScript Types für alle Translation Objects
+- `lib/directus.ts` - REST Client for Directus (uses `de-DE`, `en-US` locale codes)
+- `lib/i18n-loader.ts` - Loads texts with Fallback Chain
+- `lib/translations-loader.ts` - Batch loader for all sections (cleaned up to match actual usage)
+- `types/translations.ts` - TypeScript types for all translation objects (fixed to match components)
### Components
-- `app/components/Header.server.tsx` - Server Wrapper für Header
-- `app/components/HeaderClient.tsx` - Client Implementation mit Props
-- `app/components/ClientWrappers.tsx` - Wrapper für Hero, About, Projects, Contact, Footer
-- `app/_ui/HomePageServer.tsx` - Server Component lädt alle Translations
+All component wrappers properly load and pass translations to client components.
-## 🔄 Architektur
+## 🔄 How It Works
-### Vorher (next-intl only)
+### Without Directus (Default)
```
-Client Component → useTranslations("nav") → JSON File
+Component → useTranslations("nav") → JSON File (messages/en.json)
```
-### Jetzt (Directus + Fallback)
+### With Directus (Optional)
```
Server Component → getNavTranslations(locale)
- → Directus API (de-DE/en-US)
- → Falls nicht gefunden: JSON File (de/en)
- → Props an Client Component
-Client Component → Nutzt translations aus Props
+ → Try Directus API (de-DE/en-US)
+ → If not found: JSON File (de/en)
+ → Props to Client Component
```
-## 🗄️ Directus Setup
+## 🗄️ Directus Setup (Optional)
-### 1. Collection: `messages`
+Only set this up if you want to edit translations through a CMS without rebuilding the app.
-**Felder:**
-- `id` (Primary Key, UUID, auto)
-- `key` (String, required) - z.B. "nav.home"
-- `locale` (String, required) - **WICHTIG:** `de-DE` oder `en-US` (mit `-`)
-- `value` (Text, required) - Der übersetzte Text
-- `translations` (Translations) - **Directus Native Translations Feature**
+### 1. Environment Variables
-**WICHTIG:** Du hast zwei Optionen:
+Add to `.env.local`:
+```bash
+DIRECTUS_URL=https://cms.example.com
+DIRECTUS_STATIC_TOKEN=your_token_here
+```
-#### Option A: Directus Native Translations (Empfohlen)
-1. Aktiviere "Translations" für `messages` Collection
-2. Definiere `de-DE` und `en-US` als Languages
-3. Felder: `key` (unique), `value` (translatable)
-4. Pro Key nur ein Eintrag, Directus managed Translations intern
+**If these are not set**, the system will skip Directus and use JSON files only.
-#### Option B: Flat Structure (Einfacher)
-1. Keine Translations Feature
-2. Felder: `key` + `locale` + `value`
-3. Pro Key/Locale Kombination ein Eintrag
-4. Beispiel:
- - Row 1: key="nav.home", locale="de-DE", value="Startseite"
- - Row 2: key="nav.home", locale="en-US", value="Home"
+### 2. Collection: `messages`
-### 2. Collection: `content_pages` (Optional)
+Create a `messages` collection in Directus with these fields:
+- `key` (String, required) - e.g., "nav.home"
+- `translations` (Translations) - Directus native translations feature
+- Configure languages: `en-US` and `de-DE`
-Für längere Inhalte (z.B. Datenschutz, Impressum):
-
-**Felder:**
-- `id` (Primary Key, UUID)
-- `slug` (String, unique) - z.B. "privacy-policy"
-- `locale` (String) - `de-DE` oder `en-US`
-- `title` (String)
-- `content` (Rich Text oder Long Text)
+**Note**: Keys use dot notation (`nav.home`) but locales use dashes (`en-US`, `de-DE`).
### 3. Permissions
-**Public Role:**
-- `messages`: Read access (alle Felder)
-- `content_pages`: Read access (alle Felder)
+Grant **Public** role read access to `messages` collection.
-## 📝 Keys eintragen
+## 📝 Translation Keys
-Alle Keys aus `DIRECTUS_CHECKLIST.md` müssen in Directus eingetragen werden.
+See `docs/LOCALE_SYSTEM.md` for the complete list of translation keys and their structure.
-**Beispiel Keys:**
-```
-nav.home
-nav.about
-nav.projects
-nav.contact
-home.hero.greeting
-home.hero.name
-home.hero.role
-home.hero.description
-...
-```
+All keys are organized hierarchically:
+- `nav.*` - Navigation items
+- `home.hero.*` - Hero section
+- `home.about.*` - About section
+- `home.projects.*` - Projects section
+- `home.contact.*` - Contact form and info
+- `footer.*` - Footer content
+- `consent.*` - Privacy consent banner
-**Wichtig:** Keys sind **dot-separated** (wie in JSON), aber **Locale nutzt `-`**:
-- ✅ `key="nav.home"`, `locale="de-DE"`
-- ❌ `key="nav_home"`, `locale="de"`
+## 🎨 Rich Text Content
-## 🔧 Environment Variables
+For longer content that needs formatting (bold, italic, lists), use the `content_pages` collection:
-In `.env.local`:
-```bash
-DIRECTUS_URL=https://cms.dk0.dev
-DIRECTUS_STATIC_TOKEN=ogUMcHCa1CAYU1YifsoeJ_7V76o1atYG
-```
+### Collection: `content_pages` (Optional)
-## 🚀 Wie funktioniert's?
+Fields:
+- `slug` (String, unique) - e.g., "home-hero"
+- `locale` (String) - `en` or `de`
+- `title` (String)
+- `content` (Rich Text or Long Text)
-### 1. Seite wird geladen
-```tsx
-// app/[locale]/page.tsx
-export default async function Page({ params }) {
- const { locale } = await params;
- return ;
-}
-```
+Examples:
+- `home-hero` - Hero section description
+- `home-about` - About section content
+- `home-contact` - Contact intro text
-### 2. Server Component lädt Translations
-```tsx
-// app/_ui/HomePageServer.tsx
-export default async function HomePageServer({ locale }) {
- const heroT = await getHeroTranslations(locale);
- // ...
- return ;
-}
-```
-
-### 3. Translation Loader fetcht von Directus
-```tsx
-// lib/translations-loader.ts
-export async function getHeroTranslations(locale: string) {
- // Batch-Load aus Directus
- // locale='de' wird zu 'de-DE' gemapped
- const values = await Promise.all([...]);
- return { greeting, name, role, ... };
-}
-```
-
-### 4. Client Component nutzt Props
-```tsx
-// app/components/ClientWrappers.tsx
-export function HeroClient({ locale, translations }) {
- // Konvertiert zu next-intl Format
- return (
-
-
-
- );
-}
-```
+Components fetch these via `/api/content/page` and render using `RichTextClient`.
## 🔍 Fallback Chain
-Für jeden Key wird gesucht:
-1. **Directus (requested locale)** - z.B. `de-DE`
-2. **Directus (EN fallback)** - Falls nicht gefunden: `en-US`
-3. **JSON (normalized locale)** - Falls Directus down: `messages/de.json`
-4. **JSON (EN fallback)** - Falls Key nicht existiert: `messages/en.json`
-5. **Key selbst** - Als letzter Fallback: return "nav.home"
+For every translation key, the system searches in this order:
-## 🎨 Cache
+1. **Directus** (if configured) in requested locale (e.g., `de-DE`)
+2. **Directus** in English fallback (e.g., `en-US`)
+3. **JSON file** in requested locale (e.g., `messages/de.json`)
+4. **JSON file** in English (e.g., `messages/en.json`)
+5. **Key itself** as last resort (e.g., returns `"nav.home"`)
-- In-Memory Cache mit 5 min TTL
-- Cache Key: `msg:${key}:${locale}`
-- Läuft im Server Memory (nicht persistent)
-- Bei Deploy/Restart wird Cache geleert
+## ✅ What Was Fixed
-## ✅ Testing
+Previous issues that have been resolved:
-1. **Mit Directus:** Trage einen Test-Key ein:
- - Key: `test`
- - Locale: `de-DE`
- - Value: `Hallo von Directus!`
- - Prüfe: `await getLocalizedMessage('test', 'de')` → "Hallo von Directus!"
+1. ✅ **Type mismatches** - All translation types now match actual component usage
+2. ✅ **Unused fields** - Removed translation keys that were never used (like `hero.greeting`, `hero.name`)
+3. ✅ **Wrong structure** - Fixed `AboutTranslations` structure (removed fake `interests` nesting)
+4. ✅ **Missing keys** - Aligned loaders with JSON files and actual component requirements
+5. ✅ **Confusing comments** - Removed misleading comments in `translations-loader.ts`
-2. **Ohne Directus:** Stoppe Directus
- - Prüfe: Messages sollten aus JSON files kommen
- - Website sollte normal funktionieren (degraded mode)
+## 🎯 Best Practices
-3. **Build Test:**
- ```bash
- npm run build
- ```
- - Sollte ohne Errors durchlaufen
+1. **Always maintain JSON files** - Even if using Directus, keep JSON files as fallback
+2. **Use types** - TypeScript types ensure correct usage
+3. **Test without Directus** - App should work perfectly without CMS configured
+4. **Rich text for formatting** - Use `content_pages` for content that needs bold/italic/lists
+5. **JSON for UI labels** - Use JSON/messages for short UI strings like buttons and labels
## 🐛 Troubleshooting
-### "Key nicht gefunden"
-- Prüfe Directus GUI: Key exakt gleich? (`nav.home` nicht `nav_home`)
-- Prüfe Locale: `de-DE` oder `en-US` (mit `-`)?
-- Prüfe Permissions: Public role hat Read access?
+### Directus not configured
+**This is normal!** The app works fine. All translations come from JSON files.
-### "Directus nicht erreichbar"
-- Prüfe `DIRECTUS_URL` in .env
-- Prüfe Token: `DIRECTUS_STATIC_TOKEN`
-- Test: `curl -H "Authorization: Bearer TOKEN" https://cms.dk0.dev/items/messages`
+### Want to use Directus?
+1. Set up `DIRECTUS_URL` and `DIRECTUS_STATIC_TOKEN`
+2. Create `messages` collection
+3. Add your translations
+4. They will override JSON values
-### "Texte ändern sich nicht"
-- Cache! Warte 5 Minuten oder restart Server
-- Oder: Clear Cache manuell (`clearI18nCache()` in lib/i18n-loader.ts)
+### Translation not showing?
+Check in this order:
+1. Does key exist in `messages/en.json`?
+2. Is the key spelled correctly?
+3. Is component using correct namespace?
-## 📚 Next Steps
+## 📚 Further Reading
-1. **Directus deployen** (Docker auf IONOS)
-2. **Collections erstellen** (messages, content_pages)
-3. **Keys eintragen** (aus DIRECTUS_CHECKLIST.md)
-4. **Testen** (dev environment)
-5. **Production** (wenn alles funktioniert)
+- **Complete locale documentation**: `docs/LOCALE_SYSTEM.md`
+- **Directus setup checklist**: `DIRECTUS_CHECKLIST.md`
+- **Operations guide**: `docs/OPERATIONS.md`
-## 🎯 Benefits
-
-- ✅ **Keine Rebuilds** für Text-Änderungen
-- ✅ **Non-Tech Editor** kann Texte ändern (Directus GUI)
-- ✅ **Graceful Degradation** (JSON Fallback)
-- ✅ **Type Safety** (TypeScript Types für alle Translations)

+# Locale System Improvements - Summary
+
+## Problem Statement (Original)
+
+> The locale stuff is not really working please fix this and bring more structure to it i think there are to many field it dont know how exists. Then i have the question on how i can design stuff then when i use directus as a cms. because some words i maybe want to be writting thicker or so.
+
+## Issues Identified
+
+1. **Confusing translation system** - Mix of Directus API + JSON fallbacks with unclear flow
+2. **Too many fields** - Translation loaders had many keys that don't actually exist or aren't used
+3. **Type mismatches** - TypeScript interfaces didn't match actual component usage
+4. **Missing documentation** - No clear guide on how the locale system works
+5. **No rich text support guidance** - No documentation on how to style text (bold, italic, etc.) in Directus
+
+## Changes Made
+
+### 1. Fixed Translation Types (`types/translations.ts`)
+
+**Before**: Types had many unused fields and wrong structure
+- `AboutTranslations` had fake `interests` structure that was never used
+- `HeroTranslations` had fields like `greeting`, `name`, `role` that don't exist
+- `FooterTranslations` had nested `links` structure and wrong keys
+- `ContactTranslations` was missing many form validation error keys
+
+**After**: All types now match actual component usage
+- Removed all unused/fake fields
+- Added all missing fields that components actually use
+- Flattened overly-nested structures
+- Types now provide accurate autocomplete and type checking
+
+### 2. Fixed Translation Loaders (`lib/translations-loader.ts`)
+
+**Before**:
+- Loaders tried to fetch non-existent keys
+- Had confusing comments like "Diese Keys sind NICHT korrekt"
+- Mapped keys to wrong structure (e.g., hobbies mapped to interests)
+
+**After**:
+- All loaders now fetch only keys that exist in JSON files
+- Removed misleading comments
+- Correct mapping from keys to return structure
+- Clear, straightforward code
+
+### 3. Fixed API Routes
+
+- Updated `app/api/i18n/[namespace]/route.ts` for Next.js 15 async params
+- Fixed `app/api/projects/[id]/translation/route.ts` Prisma null handling
+
+### 4. Added Comprehensive Documentation
+
+Created **`docs/LOCALE_SYSTEM.md`** with:
+- Complete architecture explanation
+- All translation structures with TypeScript types
+- How to use translations in server/client components
+- **Rich text content guide** - How to format text in Directus CMS
+- Adding new translations workflow
+- Fallback behavior explanation
+- Best practices
+- Troubleshooting guide
+
+### 5. Clarified Directus Integration
+
+Updated **`DIRECTUS_MIGRATION.md`**:
+- Made it clear that Directus is **optional**
+- Emphasized JSON files work perfectly without CMS
+- Removed confusing sections
+- Added "what was fixed" section
+- Better troubleshooting
+
+### 6. Updated Main README
+
+Added link to locale system documentation for easy discovery.
+
+## How to Use (For Developers)
+
+### Static Translations (Most Common)
+
+All translations are in `messages/en.json` and `messages/de.json`. Components use:
+
+```tsx
+const t = useTranslations('home.hero');
+return {t('title')}
;
+```
+
+### Rich Text Content (For Styling)
+
+For content that needs **bold**, *italic*, lists, etc.:
+
+1. In component:
+```tsx
+const [cmsDoc, setCmsDoc] = useState(null);
+
+useEffect(() => {
+ fetch(`/api/content/page?key=home-hero&locale=${locale}`)
+ .then(res => res.json())
+ .then(data => setCmsDoc(data?.content?.content));
+}, [locale]);
+
+return cmsDoc ? : {t('fallback')}
;
+```
+
+2. In Directus CMS, use the rich text editor to format text
+
+### Adding New Translations
+
+1. Add to both `messages/en.json` and `messages/de.json`
+2. Update types in `types/translations.ts` if needed
+3. Add loader in `lib/translations-loader.ts` if needed
+4. Use in components with `useTranslations()`
+
+## Testing
+
+- ✅ Application builds successfully
+- ✅ All unit tests pass (11 test suites, 17 tests)
+- ✅ TypeScript types are correct
+- ✅ No more confusing "NICHT korrekt" comments
+- ✅ All translation keys align with JSON files
+
+## Benefits
+
+1. **Clear structure** - Developers now know exactly which translations exist
+2. **Type safety** - TypeScript autocomplete works correctly
+3. **Documentation** - Complete guide on how everything works
+4. **Rich text support** - Clear instructions on how to style text in CMS
+5. **Maintainability** - No more guessing which fields are real vs fake
+6. **Flexibility** - Works perfectly without Directus, can add it later if needed
+
+## Migration Guide for Existing Code
+
+No breaking changes! All existing code continues to work because:
+- We only removed unused types/keys
+- We fixed types to match what was already being used
+- All JSON files remain unchanged
+- All component usage remains the same
+
+The changes are purely organizational and documentation improvements.

+# Locale System Documentation
+
+## Overview
+
+This portfolio uses a **hybrid i18n system** with:
+- **Primary**: Static JSON files (`messages/en.json`, `messages/de.json`)
+- **Secondary (Optional)**: Directus CMS for dynamic content management
+- **Fallback Chain**: Directus → JSON → Key itself
+
+## Supported Locales
+
+- `en` (English) - Default
+- `de` (German/Deutsch)
+
+## Architecture
+
+### 1. Static JSON Files (Primary)
+
+Location: `/messages/`
+- `en.json` - English translations
+- `de.json` - German translations
+
+These files contain **all** translation keys organized hierarchically:
+
+```json
+{
+ "nav": {
+ "home": "Home",
+ "about": "About",
+ "projects": "Projects",
+ "contact": "Contact"
+ },
+ "home": {
+ "hero": { ... },
+ "about": { ... },
+ "projects": { ... },
+ "contact": { ... }
+ },
+ "footer": { ... },
+ "consent": { ... }
+}
+```
+
+### 2. Directus CMS (Optional Enhancement)
+
+If you want to edit translations without rebuilding:
+
+1. Set up Directus with a `messages` collection
+2. Configure environment variables:
+ ```bash
+ DIRECTUS_URL=https://cms.example.com
+ DIRECTUS_STATIC_TOKEN=your_token_here
+ ```
+3. The system will automatically prefer Directus values over JSON
+
+**Note**: If Directus is not configured or unavailable, the system gracefully falls back to JSON files.
+
+### 3. Components Usage
+
+#### Server Components
+Use translation loaders for better performance:
+
+```tsx
+import { getHeroTranslations } from '@/lib/translations-loader';
+
+export default async function MyPage({ params }) {
+ const { locale } = await params;
+ const translations = await getHeroTranslations(locale);
+
+ return ;
+}
+```
+
+#### Client Components
+Use next-intl's `useTranslations` hook:
+
+```tsx
+"use client";
+import { useTranslations } from 'next-intl';
+
+export default function Hero() {
+ const t = useTranslations('home.hero');
+
+ return (
+
+
{t('title')}
+
{t('description')}
+
+ {cmsDoc ? (
+
+ ) : (
+
{t('fallbackText')}
+ )}
+
