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/:

  1. hero-section.tsxfrontend/src/components/landing/hero-section.tsx

    • Badge "Now with Pro LLM Engine"
    • Titre principal
    • Description
    • Icônes des formats (xlsx, docx, pptx)
  2. site-header.tsxfrontend/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).

        </div>
      </div>
    </footer>
  )
}

🚨 Anti-Patterns à Éviter

  1. NE PAS utiliser "use client" sur page.tsx - La landing page doit être un Server Component pour le SEO et les performances

  2. NE PAS copier bêtement depuis office-translator-landing-page - Adapter les composants pour utiliser les types et le styling existants dans frontend/

  3. NE PAS créer de duplicate components - Vérifier si un composant similaire existe déjà dans frontend/src/components/ui/

  4. NE PAS inclure TranslationCard sur la landing - La translation card nécessite une authentification et est pour la page /dashboard/translate

  5. NE PAS hardcoder les couleurs - Utiliser les variables Tailwind (primary, accent, muted-foreground, etc.)

  6. 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/login ou /login → Page de connexion
  • /auth/register ou /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/ui
  • card.tsx - Card shadcn/ui
  • input.tsx - Input shadcn/ui
  • badge.tsx - Badge shadcn/ui
  • etc.

Toujours utiliser ces composants plutôt que d'en créer de nouveaux.

🧪 Tests à Effectuer

  1. Build sans erreurs: npm run build dans frontend/
  2. Rendu server-side: Vérifier que la page s'affiche sans JavaScript client
  3. Navigation: Cliquer sur tous les liens (Login, Pricing, Try Free)
  4. Responsive: Vérifier mobile vs desktop
  5. 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.

Reviewer: AI Code Review Workflow

Issues Found & Fixed

Severity Issue File Resolution
🔴 HIGH Lien "API Docs" brisé (404) site-header.tsx Redirigé vers /pricing#api
🔴 HIGH Liens Terms/Privacy brisés site-footer.tsx Redirigé vers /pricing#terms, /pricing#privacy
🔴 HIGH Code mort non nettoyé landing-sections.tsx Fichier supprimé (593 lignes)
🟡 MEDIUM 'use client' inutile hero-section.tsx Retiré → Server Component
🟡 MEDIUM 'use client' inutile features-section.tsx Déjà Server Component
🟡 MEDIUM Branding incohérent sidebar.tsx "Translate Co." → "Office Translator"

Verification

  • Build passe sans erreurs
  • 11 tests passent
  • Tous les liens internes fonctionnels
  • Aucun code mort restant

Recommendations (Post-MVP)

  1. Créer pages /terms et /privacy dédiées
  2. Créer page /docs pour documentation API
  3. Ajouter tests unitaires pour composants landing

Change Log
