### 🔄 TanStack Query Pattern
```tsx
// useAdminUsers.ts
import { useQuery } from '@tanstack/react-query'
export function useAdminUsers() {
return useQuery({
queryKey: ['admin', 'users'],
queryFn: async () => {
const token = localStorage.getItem('adminToken')
const res = await fetch(`${process.env.NEXT_PUBLIC_API_URL}/api/v1/admin/users`, {
headers: { Authorization: `Bearer ${token}` }
})
if (!res.ok) throw new Error('Failed to fetch users')
return res.json()
},
staleTime: 30000, // 30 seconds
})
}
```
```tsx
// useUpdateUserTier.ts
import { useMutation, useQueryClient } from '@tanstack/react-query'
export function useUpdateUserTier() {
const queryClient = useQueryClient()
return useMutation({
mutationFn: async ({ userId, plan }: { userId: string, plan: string }) => {
const token = localStorage.getItem('adminToken')
const res = await fetch(`${process.env.NEXT_PUBLIC_API_URL}/api/v1/admin/users/${userId}`, {
method: 'PATCH',
headers: {
Authorization: `Bearer ${token}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({ plan }),
})
if (!res.ok) throw new Error('Failed to update tier')
return res.json()
},
onSuccess: () => {
queryClient.invalidateQueries({ queryKey: ['admin', 'users'] })
},
})
}
```
### ⚠️ Points d'Attention Critiques
1. **Authentification**: Tous les appels API doivent inclure le header `Authorization: Bearer {adminToken}`. Le token est stocké dans localStorage ou Zustand store.
2. **Gestion du token admin**: Utiliser le même pattern que dans `useAdminLogin.ts` et `useAdminDashboard.ts` pour récupérer le token.
3. **Plan vs Tier**: Le backend utilise `plan` (free/starter/pro/business/enterprise) mais l'UI affiche souvent `tier` (free/pro). Mapper correctement:
- `plan: "free"` → tier: "free"
- `plan: "starter"` → tier: "free"
- `plan: "pro"` → tier: "pro"
- `plan: "business"` → tier: "pro"
- `plan: "enterprise"` → tier: "pro"
4. **Usage Calculation**: Le backend retourne `docs_translated_this_month` et `plan_limits.docs_per_month`. Calculer le pourcentage pour la progress bar.
5. **API Keys Count**: Le backend ne retourne pas directement le nombre de clés API par utilisateur. Vérifier si cette info est disponible ou masquer cette colonne.
6. **Error Handling**: Utiliser `toast` de shadcn/ui pour afficher les erreurs de manière non-intrusive.
7. **Composants shadcn/ui**: Vérifier que Table et Select sont installés. Sinon:
```bash
npx shadcn@latest add table select
```
8. **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] `useAdminUsers.ts` hook créé avec TanStack Query
- [x] `useUpdateUserTier.ts` hook créé pour les mutations
- [x] `useRevokeApiKey.ts` hook créé pour les révocations
- [x] `types.ts` créé avec interfaces TypeScript
- [x] Composants shadcn/ui disponibles (Table, Select, Progress, Badge, Tooltip)
- [x] Backend `/api/v1/admin/users` retourne les données attendues
- [x] Backend `/api/v1/admin/users/{user_id}` PATCH fonctionne
### 🚀 Integration Steps
1. **Créer types.ts** avec les interfaces TypeScript
2. **Créer useAdminUsers.ts** avec TanStack Query
3. **Créer useUpdateUserTier.ts** pour les mutations
4. **Créer useRevokeApiKey.ts** pour les révocations
5. **Créer UserStats.tsx** pour les stats cards
6. **Créer UserTable.tsx** en adaptant le design
7. **Modifier page.tsx** pour intégrer les composants
8. **Tester** avec le backend actif
### 📚 Previous Story Intelligence (Story 5.3)
**Learnings from Story 5.3 (Admin System Health Dashboard):**
- Utiliser TanStack Query `useQuery` pour le data fetching, pas de raw fetch
- Utiliser TanStack Query `useMutation` pour les mutations avec cache invalidation
- Le token admin est dans `useTranslationStore().settings.adminToken` ou localStorage
- Mapper les erreurs API vers des messages utilisateur en français
- Les composants shadcn/ui sont disponibles: Card, Button, Progress, Badge, Tooltip
- Le pattern de colocation fonctionne bien (components/hooks/types dans le dossier)
**Files created in Story 5.3:**
- `frontend/src/app/admin/types.ts` - peut être étendu ou créer types locaux
- `frontend/src/app/admin/useAdminDashboard.ts` - pattern à suivre
- `frontend/src/app/admin/useCleanup.ts` - pattern mutation à suivre
