Dev Notes
🏗️ Architecture - Frontend Stack
Technologies (depuis Story 4.1):
- Next.js: 16.0.6 (App Router)
- React: 19.2.0
- TanStack Query: v5.90.21
- Tailwind CSS: configuré
- Lucide React: pour les icônes
⚠️ Règles Critiques App Router:
🚨 FICHIERS SPÉCIAUX: page.tsx, layout.tsx → TOUJOURS minuscules
→ JAMAIS Page.tsx, Layout.tsx (le framework retourne 404)
🚨 MERGE DIRECTIVE (User Story)
CRITICAL: Deux dossiers existants
DEUX DOSSIERS EXISTANTS:
- frontend/ → Code actif (logique métier, API calls)
- office-translator-landing-page/ → Nouveau design (UI/UX, shadcn/ui)
DIRECTIVE:
1. Piocher les composants visuels depuis office-translator-landing-page/components/
2. Les intégrer dans frontend/src/components/
3. Adapter les imports pour utiliser les composants UI existants dans frontend/src/components/ui/
📁 Source Components à Migrer
Depuis office-translator-landing-page/components/:
-
hero-section.tsx →
frontend/src/components/landing/hero-section.tsx- Badge "Now with Pro LLM Engine"
- Titre principal
- Description
- Icônes des formats (xlsx, docx, pptx)
-
site-header.tsx →
frontend/src/components/layout/site-header.tsx- Logo + nom
- Navigation (Pricing, API Docs)
- Bouton Login
Attention: Le translation-card.tsx ne doit PAS être sur la landing page (c'est pour la page de traduction connectée).

🚨 Anti-Patterns à Éviter
-
NE PAS utiliser "use client" sur page.tsx - La landing page doit être un Server Component pour le SEO et les performances
-
NE PAS copier bêtement depuis office-translator-landing-page - Adapter les composants pour utiliser les types et le styling existants dans frontend/
-
NE PAS créer de duplicate components - Vérifier si un composant similaire existe déjà dans frontend/src/components/ui/
-
NE PAS inclure TranslationCard sur la landing - La translation card nécessite une authentification et est pour la page /dashboard/translate
-
NE PAS hardcoder les couleurs - Utiliser les variables Tailwind (primary, accent, muted-foreground, etc.)
-
NE PAS oublier les liens - Vérifier que /auth/register, /pricing, /dashboard existent ou redirigent correctement
📊 Routing Actuel (à vérifier)
D'après les commits récents et la structure:
/dashboard→ Dashboard principal (nécessite auth)/auth/loginou/login→ Page de connexion/auth/registerou/register→ Page d'inscription/pricing→ Page de tarification (peut ne pas exister encore)
Vérifier le routing existant avant de finaliser les liens.
🔍 Composants UI Disponibles
Depuis frontend/src/components/ui/:
button.tsx- Bouton shadcn/uicard.tsx- Card shadcn/uiinput.tsx- Input shadcn/uibadge.tsx- Badge shadcn/ui- etc.
Toujours utiliser ces composants plutôt que d'en créer de nouveaux.
🧪 Tests à Effectuer
- Build sans erreurs:
npm run builddans frontend/ - Rendu server-side: Vérifier que la page s'affiche sans JavaScript client
- Navigation: Cliquer sur tous les liens (Login, Pricing, Try Free)
- Responsive: Vérifier mobile vs desktop
- Accessibilité: Vérifier les contrastes et la navigation clavier
Project Structure Notes
- Modification:
src/app/page.tsx- Transformer en Server Component - Création:
src/components/layout/site-header.tsx- Header global - Création:
src/components/layout/site-footer.tsx- Footer global - Création:
src/components/landing/hero-section.tsx- Hero section - Création:
src/components/landing/features-section.tsx- Features (optionnel)
Note: Les composants dans layout/ sont globaux et réutilisables. Les composants dans landing/ sont spécifiques à la landing page.

Claude 3.5 Sonnet (claude-3-5-sonnet)
Debug Log References
- Build error: "m.useState is not a function" - Fixed by adding 'use client' to components using React hooks
- Build error: "React.Children.only expected to receive a single React element child" - Fixed by adding 'use client' to UI components (button.tsx, badge.tsx, input.tsx, notification.tsx, toast.tsx)
- Added
export const dynamic = 'force-dynamic'to root layout to prevent static generation issues with client components
