Major changes across backend, frontend, infrastructure: - Provider system with model selection (Google, DeepL, OpenAI, Ollama, Google Cloud) - Admin panel: user management, pricing, settings - Glossary system with CSV import/export - Subscription and tier quota management - Security hardening (rate limiting, API key auth, path traversal fixes) - Docker compose for dev, prod, and IONOS deployment - Alembic migrations for new tables - Frontend: dashboard, pricing page, landing page, i18n (en/fr) - Test suite and verification scripts Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# Story 5.3: Admin - System Health Dashboard
|
|
|
|
Status: done
|
|
|
|
## Story
|
|
|
|
En tant qu'**Admin**,
|
|
Je veux **voir les métriques de santé système en temps réel**,
|
|
de sorte que **je puisse surveiller la plateforme et réagir rapidement aux problèmes**.
|
|
|
|
## Acceptance Criteria
|
|
|
|
1. **System Health Card**: Affiche le statut global du système (healthy/unhealthy) avec indicateur animé
|
|
2. **Disk Space Card**: Affiche l'utilisation disque en pourcentage avec barre de progression
|
|
3. **Temporary Files Card**: Affiche le nombre de fichiers orphelins avec bouton de purge
|
|
4. **Provider Status Panel**: Affiche le statut de chaque provider (Google, DeepL, Ollama, OpenAI) avec latence
|
|
5. **Auto Refresh**: Les métriques se rafraîchissent automatiquement toutes les 30 secondes
|
|
6. **Manual Refresh**: Bouton pour rafraîchir manuellement les données
|
|
7. **Purge Action**: Le bouton "Purge" déclenche `/api/v1/admin/cleanup/trigger` et affiche le résultat
|
|
8. **Loading States**: États de chargement pendant les appels API
|
|
9. **Error Handling**: Gestion gracieuse des erreurs API avec message utilisateur
|
|
10. **Responsive**: S'affiche correctement sur desktop et mobile
|
|
|

## Dev Notes

|
|
|
### 🏗️ Stack Technique
|
|
|
|
| Technologie | Version |
|
|
|-------------|---------|
|
|
| Next.js | 16.0.6 (App Router) |
|
|
| React | 19.2.0 |
|
|
| TanStack Query | v5 |
|
|
| Tailwind CSS | configuré |
|
|
| shadcn/ui | Card, Button, Progress, Badge, Tooltip |
|
|
| Lucide React | HeartPulse, HardDrive, FileWarning, Trash2, Loader2, RefreshCw |
|
|
|
|
### 📁 Structure Cible (Colocation Pattern)
|
|
|
|
```
|
|
frontend/src/app/admin/
|
|
├── layout.tsx # Layout existant avec sidebar/header
|
|
├── page.tsx # ⭐ Dashboard admin principal (modifier)
|
|
├── SystemHealthCards.tsx # ⭐ Nouveau: Cards santé système
|
|
├── ProviderStatus.tsx # ⭐ Nouveau: Panel statut providers
|
|
├── useAdminDashboard.ts # ⭐ Nouveau: Hook TanStack Query
|
|
├── useCleanup.ts # ⭐ Nouveau: Hook pour purge
|
|
├── types.ts # ⭐ Nouveau: TypeScript interfaces
|
|
├── AdminSidebar.tsx # Existant (Story 5.2)
|
|
├── AdminHeader.tsx # Existant (Story 5.2)

|
├── system/ # Placeholder (Story 5.6)
|
|
└── logs/ # Placeholder (Story 5.7)
|
|
```
|
|
|
|
**⚠️ Règle absolue (architecture.md):**
|
|
```
|
|
🚨 FICHIERS SPÉCIAUX: page.tsx, layout.tsx → TOUJOURS minuscules
|
|
🚨 COLOCATION: Components/hooks/types dans le dossier de leur page
|
|
```
|
|
|
|

}
|
|
```
|
|
|
|
### 🎨 Patterns UI à Réutiliser
|
|
|
|
**SystemHealthCards.tsx** - depuis `office-translator-landing-page/components/admin-system-health.tsx`:
|
|
```tsx
|
|
// Structure à adapter
|
|
<Card className="py-0">
|
|
<CardContent className="flex items-center gap-3 px-4 py-3">
|
|
<div className="flex size-9 shrink-0 items-center justify-center rounded-lg bg-[oklch(0.59_0.16_145/0.1)]">
|
|
<HeartPulse className="size-4 text-[oklch(0.59_0.16_145)]" />
|
|
</div>
|
|
<div className="flex flex-1 flex-col gap-0.5">
|
|
<span className="text-[10px] font-medium uppercase tracking-wider text-muted-foreground">
|
|
Server Health
|
|
</span>
|
|
<div className="flex items-center gap-1.5">
|
|
<span className="relative flex size-2">
|
|
<span className="absolute inline-flex size-full animate-ping rounded-full bg-[oklch(0.59_0.16_145)] opacity-75" />
|
|
<span className="relative inline-flex size-2 rounded-full bg-[oklch(0.59_0.16_145)]" />
|
|
</span>
|
|
<span className="text-sm font-semibold text-foreground">All Systems Operational</span>
|
|
</div>
|
|
</div>
|
|
</CardContent>
|
|
</Card>
|
|
```
|
|
|
|
**ProviderStatus.tsx** - depuis `office-translator-landing-page/components/admin-provider-status.tsx`:
|
|
```tsx
|
|
// Structure à adapter
|
|
<div className="flex flex-wrap items-center gap-2">
|
|
{providers.map((provider) => (
|
|
<Tooltip key={provider.name}>
|
|
<TooltipTrigger asChild>
|
|
<Badge variant="outline" className="gap-1.5 px-2.5 py-1">
|
|
<span className="size-1.5 rounded-full bg-green-500" />
|
|
{provider.name}
|
|
</Badge>
|
|
</TooltipTrigger>
|
|
<TooltipContent>
|
|
<span>Latency: {provider.latency}</span>
|
|
</TooltipContent>
|
|
</Tooltip>
|
|
))}
|
|
</div>
|
|
```
|
|
|
|
### 🔄 TanStack Query Pattern
|
|
|
|
```tsx
|
|
// useAdminDashboard.ts
|
|
import { useQuery } from '@tanstack/react-query'
|
|
|
|
export function useAdminDashboard() {
|
|
return useQuery({
|
|
queryKey: ['admin', 'dashboard'],
|
|
queryFn: async () => {
|
|
const token = localStorage.getItem('adminToken')
|
|
const res = await fetch(`${process.env.NEXT_PUBLIC_API_URL}/api/v1/admin/dashboard`, {
|
|
headers: { Authorization: `Bearer ${token}` }
|
|
})
|
|
if (!res.ok) throw new Error('Failed to fetch dashboard')
|
|
return res.json()
|
|
},
|
|
refetchInterval: 30000, // 30 seconds
|
|
staleTime: 10000,
|
|
})
|
|
}
|
|
```
|
|
|
|
### ⚠️ Points d'Attention Critiques
|
|
|
|
1. **Authentification**: Tous les appels API doivent inclure le header `Authorization: Bearer {adminToken}`. Le token est stocké dans le Zustand store: `useTranslationStore().settings.adminToken`.
|
|
|
|
2. **Gestion du token admin**: Utiliser le même pattern que dans `useAdminLogin.ts` pour récupérer le token depuis le store.
|
|
|
|
3. **Provider Status Mapping**: Le backend retourne `available: true/false`. Mapper vers les états visuels:
|
|
- `available: true` → "online" (vert)
|
|
- `available: false` → "offline" (rouge)
|
|
- Pas de réponse → "degraded" (jaune)
|
|
|
|
4. **Zustand Store Access**: Le token est dans `useTranslationStore().settings.adminToken`. Vérifier que le store est accessible.
|
|
|
|
5. **Error Handling**: Utiliser `toast` de shadcn/ui pour afficher les erreurs de manière non-intrusive.
|
|
|
|
6. **Composants shadcn/ui**: Vérifier que Progress et Tooltip sont installés. Sinon:
|
|
```bash
|
|
npx shadcn@latest add progress tooltip
|
|
```
|
|
|
|
7. **Couleurs OKLCH**: Le design utilise des couleurs OKLCH modernes. Si le projet ne les supporte pas, utiliser des classes Tailwind standard.
|
|
|
|
### 📋 Checklist de Validation Avant Dev
|
|
|
|
- [x] `useAdminDashboard.ts` hook créé avec TanStack Query
|
|
- [x] `useCleanup.ts` hook créé pour la purge
|
|
- [x] `types.ts` créé avec interfaces TypeScript
|
|
- [x] Composants shadcn/ui disponibles (Card, Button, Progress, Badge, Tooltip)
|
|
- [x] Backend `/api/v1/admin/dashboard` retourne les données attendues
|
|
- [x] Backend `/api/v1/admin/cleanup/trigger` fonctionne
|
|
|
|
### 🚀 Integration Steps
|
|
|
|
1. **Créer types.ts** avec les interfaces TypeScript
|
|
2. **Créer useAdminDashboard.ts** avec TanStack Query
|
|
3. **Créer useCleanup.ts** pour la purge
|
|
4. **Créer SystemHealthCards.tsx** en adaptant le design
|
|
5. **Créer ProviderStatus.tsx** en adaptant le design
|
|
6. **Modifier page.tsx** pour intégrer les composants
|
|
7. **Tester** avec le backend actif
