# 📝 IMPORTANT - Structure des Documentation
## ✅ RÈGLE : Tous les .md (SAUF README.md) doivent être dans `.claude/`
**Raison:** Garder la racine minimale et propre.
### Fichiers à TOUJOURS garder dans `.claude/`:
- ✅ `POSTQUANTUM_CRYPTO.md` - Documentation PQC
- ✅ `DEPLOYMENT.md` - Guide de déploiement
- ✅ `STATUS.md` - Status du projet (MOVE HERE!)
- ✅ Tout autre .md technique
### Fichiers à la RACINE:
- ✅ `README.md` SEULEMENT
### À FAIRE:
```bash
# Déplacer STATUS.md vers .claude/
mv STATUS.md .claude/STATUS.md
git add -A && git commit -m "Move STATUS.md to .claude/"
```

import { useForm } from '../hooks/useApi';
function MyForm() {
const { values, errors, handleChange, handleSubmit } = useForm(
{ email: '', password: '' },
async (values) => {
// Submit logic
}
);
return (
<form onSubmit={handleSubmit}>
<input
name="email"
value={values.email}
onChange={handleChange}
/>
{errors.email && <span>{errors.email}</span>}
<button type="submit">Envoyer</button>
</form>
);
}
```
### Pattern 2: Chargement de Données
```jsx
import { useApi } from '../hooks/useApi';
function MyComponent() {
const { data, loading, error } = useApi('/api/endpoint');
if (loading) return <LoadingSpinner />;
if (error) return <Alert type="error" message={error} />;
return <div>{data}</div>;
}
```
### Pattern 3: Modal de Confirmation
```jsx
function MyComponentWithConfirmation() {
const [showModal, setShowModal] = useState(false);
const handleDelete = async () => {
// Delete logic
setShowModal(false);
};
return (
<>
<button onClick={() => setShowModal(true)}>Supprimer</button>
<Modal
isOpen={showModal}
title="Confirmer la suppression"
onClose={() => setShowModal(false)}
onConfirm={handleDelete}
type="danger"
>
<p>Cette action est irréversible.</p>
</Modal>
</>
);
}
```
---
## Styling des Composants
Tous les composants utilisent des classes CSS dans le fichier `styles/components.css`.
### Classes Disponibles
```html
<!-- Boutons -->
<button class="btn btn-primary">Primaire</button>
<button class="btn btn-secondary">Secondaire</button>
<button class="btn btn-success">Succès</button>
<button class="btn btn-danger">Danger</button>
<button class="btn btn-warning">Warning</button>
<button class="btn btn-ghost">Ghost</button>
<!-- Tailles -->
<button class="btn btn-sm">Petit</button>
<button class="btn btn-lg">Grand</button>
<!-- Autre -->
<button class="btn btn-block">Pleine largeur</button>
```
### Personnalisation
Modifiez les styles dans `src/styles/components.css`:
```css
.btn-primary {
background-color: var(--primary-blue);
/* ... */
}
```
---
## Accessibilité
Tous les composants respectent les standards WCAG 2.1:
- ✅ Navigation au clavier (Tab, Enter, Escape)
- ✅ Contraste de couleur minimum AA
- ✅ Textes alternatifs pour les icônes
- ✅ Labels associés aux inputs
- ✅ Sémantique HTML correcte
- ✅ Focus visible
- ✅ Aria attributes
### Exemple
```jsx
<button
aria-label="Fermer le menu"
onClick={close}
>
✕
</button>
```
---
## Performance
### Code Splitting
Utilisez `React.lazy()` pour charger les pages à la demande:
```jsx
const DashboardPage = React.lazy(() => import('./pages/DashboardPage'));
<Suspense fallback={<LoadingSpinner />}>
<DashboardPage />
</Suspense>
```
### Memoization
Pour les composants coûteux:
```jsx
import { memo } from 'react';
const VoteCard = memo(({ vote, onVote }) => {
// Component
});
```
---
## Troubleshooting
### Le composant ne s'affiche pas
1. Vérifiez que les props requises sont passées
2. Vérifiez les erreurs dans la console
3. Vérifiez les imports
### Les styles ne s'appliquent pas
1. Vérifiez que le CSS est importé dans `index.js`
2. Vérifiez la spécificité des classes CSS
3. Utilisez DevTools pour inspecter les styles
### Le composant est lent
1. Utilisez `React.memo()` si le composant dépend de props simples
2. Utilisez `useMemo()` pour les calculs coûteux
3. Vérifiez les rendus inutiles avec DevTools
---
## Améliorations Futures
- [ ] Ajouter des animations avec Framer Motion
- [ ] Ajouter un thème sombre
- [ ] Composants Storybook
- [ ] Tests unitaires pour tous les composants
- [ ] Gérer l'internationalization (i18n)

## 🎨 Personnalisation du Design
### Couleurs
Les couleurs sont définies dans `src/styles/globals.css`:
```css
:root {
--primary-dark: #1e3a5f;
--primary-blue: #2563eb;
--success-green: #10b981;
--warning-orange: #f97316;
--danger-red: #ef4444;
/* ... */
}
```
Pour modifier:
1. Ouvrez `src/styles/globals.css`
2. Changez les valeurs des variables CSS
### Fonts
Modifiez dans `src/styles/globals.css`:
```css
--font-primary: "Inter", "Segoe UI", "Roboto", sans-serif;
```
### Espacements et Radius
Ils sont aussi en variables CSS. Modifiez-les globalement pour changer tout le design.
## 🔄 Navigation
### Pages Publiques
- **`/`** - Accueil
- **`/login`** - Connexion
- **`/register`** - Inscription
- **`/archives`** - Votes terminés
### Pages Privées (après connexion)
- **`/dashboard`** - Tableau de bord
- **`/vote/:id`** - Page de vote
- **`/profile`** - Profil utilisateur
## 🔌 Intégration Backend
### Configuration de l'API
Modifiez l'URL de l'API dans `src/utils/api.js`:
```javascript
const API_URL = process.env.REACT_APP_API_URL || 'http://localhost:8000';
```
### Exemples d'Appels API
```javascript
import { APIClient } from './utils/api';
// Connexion
const data = await APIClient.login('user@example.com', 'password');
// Récupérer les votes
const votes = await APIClient.getElections();
// Voter
const result = await APIClient.submitVote(electionId, 'Oui');
```
## 🧪 Tests
```bash
# Lancer les tests
npm test
# Tests avec couverture
npm test -- --coverage
# Tests en mode watch
npm test -- --watch
```
## 🏗️ Build pour Production
```bash
# Créer un build optimisé
npm run build
# Le build sera créé dans le dossier `build/`
```
## 🐛 Debugging
### Console du Navigateur
1. Ouvrez DevTools: `F12` ou `Ctrl+Shift+I` (Windows/Linux) / `Cmd+Option+I` (Mac)
2. Allez à l'onglet "Console"
3. Vérifiez les erreurs
### React DevTools
Installez l'extension [React DevTools](https://react-devtools-tutorial.vercel.app/) pour votre navigateur.
### Redux DevTools (optionnel)
Si vous utilisez Redux, installez [Redux DevTools](https://github.com/reduxjs/redux-devtools).
## 📱 Responsive Design
Le design est optimisé pour:
- **Desktop**: 1024px+
- **Tablet**: 768px - 1024px
- **Mobile**: < 768px
Testez sur mobile:
1. Ouvrez DevTools (`F12`)
2. Cliquez sur l'icône "Toggle device toolbar"
3. Sélectionnez un appareil mobile
## ⚡ Performance
### Optimisation des Images
Utilisez des images compressées. Outils recommandés:
- TinyPNG
- ImageOptim
- GIMP
### Code Splitting
Déjà implémenté avec `React.lazy()` et `Suspense`.
### Caching
Le navigateur cache automatiquement les fichiers statiques. Pour forcer un refresh:
`Ctrl+Shift+R` (Windows/Linux) / `Cmd+Shift+R` (Mac)
## 🔒 Sécurité
### Authentification
- Le token JWT est stocké dans localStorage
- À inclure dans le header `Authorization` pour les requêtes privées
- Stocké automatiquement après la connexion
### Validation des Données
Tous les formulaires sont validés côté client:
- Email valide
- Mot de passe minimum 8 caractères
- Confirmation de mot de passe
### HTTPS en Production
Assurez-vous d'utiliser HTTPS en production pour sécuriser les données.
## 🌍 Internationalisation (i18n)
Pour ajouter plusieurs langues:
1. Installez `i18next`:
```bash
npm install i18next i18next-react-backend i18next-browser-languagedetector
```
2. Créez des fichiers de traduction dans `src/locales/`
3. Configurez i18next dans `src/i18n.js`
