# Locale/i18n Implementation Status Report
**Generated**: 2026-01-13 21:01:11 CET
**Project**: AI Stack Deployer
**Branch**: dev
---
## Executive Summary
**Locale system is FULLY IMPLEMENTED and OPERATIONAL**
The project has a complete multilingual system supporting **3 languages** (English, Dutch, Arabic) across both frontend and backend. No dedicated "locale" folder exists—translations are embedded within the codebase using modern inline patterns.
---
## Architecture Overview
### Two-Tier i18n System
```
┌─────────────────────────────────────┐
│ Frontend (React Client) │
│ - client/src/lib/i18n.ts │
│ - client/src/hooks/useI18n.ts │
│ - LanguageSelector component │
│ - Translations: EN, NL, AR │
└──────────────┬──────────────────────┘
│ (sends lang preference)
┌──────────────▼──────────────────────┐
│ Backend (Hono API) │
│ - src/lib/i18n-backend.ts │
│ - Deployment progress messages │
│ - Translations: EN, NL, AR │
└─────────────────────────────────────┘
```
---
## Implementation Details
### 1. Frontend i18n System
**Location**: `client/src/lib/i18n.ts`
**Features**:
- ✅ Three languages: English (en), Dutch (nl), Arabic (ar)
- ✅ 33 translation keys per language
- ✅ Auto-detection from browser locale
- ✅ Persistent user preference (localStorage)
- ✅ RTL support for Arabic
- ✅ Type-safe translation keys
**Key Files**:
```
client/src/
├── lib/
│ └── i18n.ts # Translation strings + utilities
├── hooks/
│ └── useI18n.ts # React hook for translations
└── components/
└── deploy/
└── LanguageSelector.tsx # Language switcher UI (NL/AR/EN)
```
**Translation Coverage**:
- Form labels and placeholders
- Validation messages
- Deployment status messages
- Success/error screens
- UI buttons and actions
**Example Translation**:
```typescript
en: {
title: 'AI Stack Deployer',
subtitle: 'Deploy your personal AI assistant in seconds',
deployBtn: 'Deploy My AI Stack',
// ... 30 more keys
}
nl: {
title: 'AI Stack Deployer',
subtitle: 'Implementeer je persoonlijke AI in seconden',
deployBtn: 'Implementeer Mijn AI Stack',
// ... 30 more keys
}
ar: {
title: 'AI Stack Deployer',
subtitle: 'انشر مساعد البرمجة الذكي الخاص بك في ثوانٍ',
deployBtn: 'انشر مشروعي',
// ... 30 more keys
}
```
---
### 2. Backend i18n System
**Location**: `src/lib/i18n-backend.ts`
**Features**:
- ✅ Deployment progress messages in 3 languages
- ✅ Receives language preference from frontend
- ✅ Sends localized SSE events during deployment
- ✅ Factory pattern with `createTranslator()`
**Translation Keys** (14 keys per language):
- `initializing` - "Initializing deployment"
- `creatingProject` - "Creating project"
- `creatingApplication` - "Creating application"
- `waitingForSSL` - "Waiting for SSL certificate..."
- `deploymentSuccess` - "Application deployed successfully"
- ... and 9 more
**Integration Points**:
```typescript
// src/orchestrator/production-deployer.ts
const t = createTranslator(lang); // lang from request
progress.update(50, t('creatingApplication'));
```
---
### 3. Components Using i18n
**All deployment components are multilingual**:
| Component | File | Purpose |
|-----------|------|---------|
| DeployPage | `client/src/pages/DeployPage.tsx` | Main page, language state |
| DeployForm | `client/src/components/deploy/DeployForm.tsx` | Form with validation |
| DeployProgress | `client/src/components/deploy/DeployProgress.tsx` | Progress tracking |
| DeploySuccess | `client/src/components/deploy/DeploySuccess.tsx` | Success screen |
| DeployError | `client/src/components/deploy/DeployError.tsx` | Error screen |
| LanguageSelector | `client/src/components/deploy/LanguageSelector.tsx` | Language switcher |
**Usage Pattern**:
```tsx
const { lang, setLang, t, isRtl } = useI18n();
return <h1>{t('title')}</h1>; // Auto-translated
```
---

---
## Technical Decisions
### Why No Separate Locale Folder?
**Modern Inline Pattern**: Translations are co-located with code for:
- ✅ Better type safety (TypeScript can validate keys)
- ✅ Easier refactoring (IDE can track references)
- ✅ Simpler imports (no file lookup)
- ✅ Reduced bundle size (no extra JSON parsing)
**Traditional Approach** (NOT used):
```
locales/
├── en.json
├── nl.json
└── ar.json
```
**Current Approach** (Used):
```typescript
// All in client/src/lib/i18n.ts
export const translations = {
en: { ... },
nl: { ... },
ar: { ... }
} as const;
```
---
## Language Support Details
### 1. English (en)
- **Status**: ✅ Complete (default language)
- **Coverage**: 100% (33 frontend + 14 backend keys)
- **Notes**: Fallback language if translation missing
### 2. Dutch (nl)
- **Status**: ✅ Complete
- **Coverage**: 100% (33 frontend + 14 backend keys)
- **Notes**: Primary target language for Dutch users
- **Quality**: Professional translations
### 3. Arabic (ar)
- **Status**: ✅ Complete with RTL support
- **Coverage**: 100% (33 frontend + 14 backend keys)
- **RTL**: Automatic direction switching (`dir="rtl"`)
- **Notes**: Full right-to-left layout support
---
## Features & Capabilities
### Frontend Features
**Automatic Language Detection**
```typescript
const browserLang = navigator.language?.split('-')[0];
// Auto-selects 'nl' if browser is nl-NL, nl-BE, etc.
```
**Persistent Preference**
```typescript
localStorage.setItem('preferredLanguage', 'nl');
// Remembered across sessions
```
**RTL Support**
```typescript
document.documentElement.dir = lang === 'ar' ? 'rtl' : 'ltr';
// Entire layout flips for Arabic
```
**Type Safety**
```typescript
type TranslationKey = keyof typeof translations.en;
// TypeScript prevents typos in translation keys
```
### Backend Features
**Language-Aware Deployment**
```typescript
POST /api/deploy
{ "name": "john-dev", "lang": "nl" }
// Backend sends Dutch progress messages
```
**SSE Localized Events**
```javascript
event: progress
data: {"progress": 50, "currentStep": "Applicatie aanmaken"} // Dutch
```
---
## SEO & Metadata
### HTML Meta Tags (src/frontend/index.html)
**Dutch-First SEO** (commit `897a828`):
```html
<html lang="en">
<meta property="og:locale" content="nl_NL">
<title>AI Stack Deployer - Persoonlijke AI Assistent Deployen | FLEXINIT</title>
<meta name="description" content="Deploy je persoonlijke AI assistent in seconden...">
```
**Social Media Previews**:
- Open Graph tags (Facebook, LinkedIn)
- Twitter Card tags
- 1200x630 social preview image (`og-image.png`)
- Image alt text in Dutch
**Structured Data**:
```json
{
"@context": "https://schema.org",
"@type": "WebApplication",
"name": "AI Stack Deployer",
"applicationCategory": "DeveloperApplication"
}
```
---
## Testing Status
### Frontend i18n Tests
- ❌ No automated tests (manual testing only)
- ✅ Manual verification: All 3 languages render correctly
- ✅ RTL layout verified for Arabic
### Backend i18n Tests
- ❌ No automated tests
- ✅ Manual verification: SSE events show correct language
### Missing Test Coverage
```
[ ] Unit tests for translation functions
[ ] E2E tests for language switching
[ ] Visual regression tests for RTL layout
[ ] Integration tests for backend translations
```

---
## Next Steps & Recommendations
### Immediate Actions (Priority 1)
1. ⚠️ **Clean up deprecated files**
- `src/frontend/` is no longer served (React client replaced it)
- Consider archiving or deleting old vanilla JS files
- Update documentation to reflect React-only architecture
2. ⚠️ **Add translation tests**
```bash
# Missing test coverage
client/src/lib/__tests__/i18n.test.ts
src/lib/__tests__/i18n-backend.test.ts
```
### Future Enhancements (Priority 2)
3. 📝 **Add more languages**
- French (fr) - Belgium market
- German (de) - DACH region
- Spanish (es) - Global reach
4. 📝 **Extract translations to JSON** (if team prefers)
```
client/src/locales/
├── en.json
├── nl.json
└── ar.json
```
5. 📝 **Add translation management**
- Consider tools like i18next, react-intl
- Or maintain current simple system (works great for 3 languages)
### Documentation Updates (Priority 3)
6. 📝 **Update CLAUDE.md**
- Document i18n system architecture
- Add guidelines for adding new translation keys
- Explain why no separate locale folder exists
7. 📝 **Update README.md**
- Add "Multilingual Support" section
- Show how to add new languages
- Document translation contribution process
---

## 🔥 Current Priority (HIGH)
### 1. Automated Cleanup System ⚠️ CRITICAL
**Problem**: Disk space exhaustion on Dokploy server (10.100.0.20) causes CI failures
**Target**: Keep 15GB+ free space (85% max usage)
**Components to Implement**:
```
[ ] CI workflow cleanup step
└─ Prune build cache after each build (keep 2GB)
└─ Remove images older than 24h
[ ] Server-side cron job
└─ Daily Docker system prune at 4 AM
└─ Remove volumes older than 72h
└─ Prune flexinit-runner builder cache (keep 5GB)
[ ] Disk monitoring
└─ Grafana alerts at 80% usage
└─ Slack/email notifications
[ ] Post-deployment cleanup
└─ Remove unused resources after stack deploy
```
**Implementation Files**:
- `.gitea/workflows/*.yaml` - Add cleanup steps
- `/etc/cron.d/docker-cleanup` on 10.100.0.20 - Cron job
- Grafana alert rules
**Current Disk Usage** (97GB total):
- Docker images: ~10GB
- Containers: ~1.5GB
- Volumes: ~30GB
- Build cache: Up to 6GB (needs pruning)
---
### 2. Web-based TUI Support 🚧 IN PROGRESS
**Goal**: Enable rich terminal UI apps (htop, lazygit, OpenCode TUI mode) in browser
**Completed** (Terminal Environment):
- ✅ TERM=xterm-256color
- ✅ COLORTERM=truecolor (24-bit color)
- ✅ ncurses-base and ncurses-term packages
- ✅ Locale configuration (en_US.UTF-8)
- ✅ Environment variables passed to stacks
**Remaining** (Direct Web Terminal):
```
[ ] Add ttyd to stack Docker image
[ ] Configure dual-port exposure:
├─ Port 8080 → OpenCode Web IDE
└─ Port 7681 → ttyd Raw Terminal
[ ] Update Traefik routing for terminal port
[ ] Test TUI applications:
├─ htop, btop (system monitoring)
├─ lazygit, lazydocker
├─ vim/neovim with full features
└─ OpenCode TUI mode
[ ] Document TUI capabilities for users
```
**Architecture**:
```
https://name.ai.flexinit.nl/ → OpenCode Web IDE
https://name.ai.flexinit.nl:7681/ → ttyd Raw Terminal
```
**Use Cases**:
- OpenCode TUI mode in browser
- Git TUIs (lazygit, tig)
- System monitoring (htop, btop)
- vim/neovim with full ncurses support
- Any ncurses-based application
