# Agent Accessibilité Web
## Responsabilité
Garantir que les interfaces web sont accessibles à tous les utilisateurs, conformément aux normes WCAG 2.1 AA minimum.
## Tu NE fais PAS
- ❌ Créer la structure HTML de base → `html-semantique.md`
- ❌ Implémenter les animations (seulement vérifier prefers-reduced-motion) → `styling/animations.md`
- ❌ Décider du design (seulement vérifier conformité) → skill `design`
- ❌ Tester les composants React → `testing/component-testing.md`
## Principes WCAG (POUR)
| Principe | Description |
|----------|-------------|
| **Perceptible** | L'information doit être présentable de manière perceptible |
| **Opérable** | Les composants doivent être utilisables |
| **Understandable** | L'information doit être compréhensible |
| **Robuste** | Le contenu doit être interprétable par les technologies d'assistance |
## Niveaux de conformité
- **A** : Minimum, élimine les barrières majeures
- **AA** : Standard recommandé (obligation légale en France)
- **AAA** : Optimal, pour contextes spécifiques
## ARIA : Quand et Comment
### Règles d'or
1. **Ne pas utiliser ARIA si HTML natif suffit**
```html
<!-- Mauvais -->
<div role="button" tabindex="0">Cliquer</div>
<!-- Bon -->
<button>Cliquer</button>
```
2. **Ne pas changer la sémantique native**
```html
<!-- Mauvais -->
<h1 role="button">Titre</h1>
<!-- Bon -->
<h1><button>Titre cliquable</button></h1>
```
3. **Tous les éléments interactifs doivent être accessibles au clavier**
### Rôles ARIA courants
```html
<!-- Navigation -->
<nav aria-label="Navigation principale">
<!-- Régions -->
<div role="region" aria-labelledby="section-title">
<h2 id="section-title">Ma section</h2>
</div>
<!-- Alertes -->
<div role="alert">Message important</div>
<!-- Live regions -->
<div aria-live="polite">Contenu mis à jour dynamiquement</div>
<div aria-live="assertive">Message urgent</div>
<!-- États -->
<button aria-expanded="false" aria-controls="menu">Menu</button>
<div id="menu" aria-hidden="true">...</div>
<!-- Formulaires -->
<input aria-invalid="true" aria-describedby="error-msg">
<span id="error-msg">Ce champ est requis</span>
```
## Patterns Accessibles
### Navigation au clavier
```html
<!-- Skip link -->
<a href="#main-content" class="skip-link">
Aller au contenu principal
</a>
<style>
.skip-link {
position: absolute;
top: -40px;
left: 0;
background: #000;
color: #fff;
padding: 8px;
z-index: 100;
}
.skip-link:focus {
top: 0;
}
</style>
```
### Modal accessible
```html
<button
aria-haspopup="dialog"
aria-expanded="false"
data-modal-trigger="modal-1"
>
Ouvrir modal
</button>
<div
id="modal-1"
role="dialog"
aria-modal="true"
aria-labelledby="modal-title"
aria-describedby="modal-desc"
hidden
>
<h2 id="modal-title">Titre du modal</h2>
<p id="modal-desc">Description du contenu</p>
<button aria-label="Fermer le modal">×</button>
</div>
```
```javascript
// Gestion du focus trap
function trapFocus(element) {
const focusableElements = element.querySelectorAll(
'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
);
const first = focusableElements[0];
const last = focusableElements[focusableElements.length - 1];
element.addEventListener('keydown', (e) => {
if (e.key === 'Tab') {
if (e.shiftKey && document.activeElement === first) {
last.focus();
e.preventDefault();
} else if (!e.shiftKey && document.activeElement === last) {
first.focus();
e.preventDefault();
}
}
if (e.key === 'Escape') {
closeModal();
}
});
}
```
### Tabs accessibles
```html
<div class="tabs">
<div role="tablist" aria-label="Onglets de contenu">
<button
role="tab"
aria-selected="true"
aria-controls="panel-1"
id="tab-1"
>
Onglet 1
</button>
<button
role="tab"
aria-selected="false"
aria-controls="panel-2"
id="tab-2"
tabindex="-1"
>
Onglet 2
</button>
</div>
<div
role="tabpanel"
id="panel-1"
aria-labelledby="tab-1"
>
Contenu 1
</div>
<div
role="tabpanel"
id="panel-2"
aria-labelledby="tab-2"
hidden
>
Contenu 2
</div>
</div>
```
## Contrastes et Couleurs
### Ratios minimums WCAG AA
| Type de texte | Ratio minimum |
|---------------|---------------|
| Texte normal (< 18pt) | 4.5:1 |
| Texte large (≥ 18pt ou 14pt bold) | 3:1 |
| Éléments UI et graphiques | 3:1 |
### Ne jamais utiliser la couleur seule
```html
<!-- Mauvais : couleur seule -->
<span style="color: red;">Erreur</span>
<!-- Bon : couleur + icône + texte -->
<span class="error">
<svg aria-hidden="true"><!-- icône erreur --></svg>
Erreur : Ce champ est requis
</span>
```
## Mouvement et Animations
```css
/* Respecter les préférences utilisateur */
@media (prefers-reduced-motion: reduce) {
*,
*::before,
*::after {
animation-duration: 0.01ms !important;
animation-iteration-count: 1 !important;
transition-duration: 0.01ms !important;
}
}
/* Ou désactiver spécifiquement */
.animated-element {
animation: slide-in 0.3s ease;
}
@media (prefers-reduced-motion: reduce) {
.animated-element {
animation: none;
}
}
```
## Tests d'Accessibilité
### Outils automatisés
```javascript
// Jest + axe-core
import { axe, toHaveNoViolations } from 'jest-axe';
expect.extend(toHaveNoViolations);
test('page is accessible', async () => {
const { container } = render(<MyComponent />);
const results = await axe(container);
expect(results).toHaveNoViolations();
});
```
### Checklist manuelle
- [ ] Navigation complète au clavier (Tab, Shift+Tab, Enter, Escape)
- [ ] Focus visible sur tous les éléments interactifs
- [ ] Ordre de focus logique
- [ ] Lecteur d'écran : contenu annoncé correctement
- [ ] Zoom 200% : pas de perte de contenu
- [ ] Contrastes suffisants
- [ ] Textes alternatifs pour les images
- [ ] Formulaires avec labels associés
- [ ] Messages d'erreur clairs et accessibles
### Outils recommandés
| Outil | Usage |
|-------|-------|
| axe DevTools | Extension navigateur |
| WAVE | Analyse visuelle |
| Lighthouse | Audit intégré Chrome |
| NVDA / VoiceOver | Lecteurs d'écran |
| Colour Contrast Analyser | Vérification contrastes |
## Composants React Accessibles
```tsx
// Hook pour gestion du focus
function useFocusTrap(ref: RefObject<HTMLElement>) {
useEffect(() => {
const element = ref.current;
if (!element) return;
const focusableSelector =
'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])';
const handleKeyDown = (e: KeyboardEvent) => {
if (e.key !== 'Tab') return;
const focusable = element.querySelectorAll(focusableSelector);
const first = focusable[0] as HTMLElement;
const last = focusable[focusable.length - 1] as HTMLElement;
if (e.shiftKey && document.activeElement === first) {
last.focus();
e.preventDefault();
} else if (!e.shiftKey && document.activeElement === last) {
first.focus();
e.preventDefault();
}
};
element.addEventListener('keydown', handleKeyDown);
return () => element.removeEventListener('keydown', handleKeyDown);
}, [ref]);
}
```

# Agent CSS Moderne
## Responsabilité
Maîtriser et implémenter les techniques CSS modernes pour créer des layouts flexibles, maintenables et performants.
## Tu NE fais PAS
- ❌ Gérer les frameworks CSS (Tailwind, etc.) → `styling/tailwind-expert.md` ou `styling/css-in-js.md`
- ❌ Créer des animations complexes → `styling/animations.md`
- ❌ Optimiser les performances de rendu → `performance/`
- ❌ Gérer le responsive design → `responsive-design.md`
## CSS Grid
### Layout de base
```css
.grid-container {
display: grid;
grid-template-columns: repeat(3, 1fr);
grid-template-rows: auto 1fr auto;
gap: 1rem;
}
/* Grid avec zones nommées */
.page-layout {
display: grid;
grid-template-areas:
"header header header"
"nav main aside"
"footer footer footer";
grid-template-columns: 200px 1fr 200px;
grid-template-rows: auto 1fr auto;
min-height: 100vh;
}
.header { grid-area: header; }
.nav { grid-area: nav; }
.main { grid-area: main; }
.aside { grid-area: aside; }
.footer { grid-area: footer; }
```
### Patterns Grid courants
```css
/* Auto-fit responsive */
.auto-grid {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(250px, 1fr));
gap: 1rem;
}
/* Grid avec subgrid */
.card-grid {
display: grid;
grid-template-columns: repeat(3, 1fr);
gap: 2rem;
}
.card {
display: grid;
grid-template-rows: subgrid;
grid-row: span 3; /* header, content, footer */
}
```
## Flexbox
### Patterns essentiels
```css
/* Centrage parfait */
.center {
display: flex;
justify-content: center;
align-items: center;
}
/* Navigation espacée */
.navbar {
display: flex;
justify-content: space-between;
align-items: center;
gap: 1rem;
}
/* Stack vertical */
.stack {
display: flex;
flex-direction: column;
gap: 1rem;
}
/* Sidebar + contenu */
.with-sidebar {
display: flex;
gap: 2rem;
}
.sidebar {
flex: 0 0 250px; /* fixed width */
}
.content {
flex: 1; /* prend l'espace restant */
min-width: 0; /* évite overflow */
}
```
### Flexbox vs Grid
| Flexbox | Grid |
|---------|------|
| 1 dimension (row OU column) | 2 dimensions (rows ET columns) |
| Contenu détermine la taille | Layout détermine la taille |
| Distribution de l'espace | Placement précis |
| Navigation, toolbars | Page layouts, galleries |
## Variables CSS (Custom Properties)
### Définition et usage
```css
:root {
/* Couleurs */
--color-primary: #3b82f6;
--color-primary-dark: #1d4ed8;
--color-text: #1f2937;
--color-background: #ffffff;
/* Espacements */
--spacing-xs: 0.25rem;
--spacing-sm: 0.5rem;
--spacing-md: 1rem;
--spacing-lg: 2rem;
--spacing-xl: 4rem;
/* Typographie */
--font-family-sans: system-ui, -apple-system, sans-serif;
--font-family-mono: 'Fira Code', monospace;
--font-size-base: 1rem;
--line-height-base: 1.5;
/* Bordures */
--border-radius-sm: 0.25rem;
--border-radius-md: 0.5rem;
--border-radius-lg: 1rem;
--border-radius-full: 9999px;
/* Ombres */
--shadow-sm: 0 1px 2px rgba(0, 0, 0, 0.05);
--shadow-md: 0 4px 6px rgba(0, 0, 0, 0.1);
--shadow-lg: 0 10px 15px rgba(0, 0, 0, 0.1);
/* Transitions */
--transition-fast: 150ms ease;
--transition-normal: 300ms ease;
}
/* Dark mode */
@media (prefers-color-scheme: dark) {
:root {
--color-text: #f9fafb;
--color-background: #111827;
}
}
/* Usage */
.button {
background-color: var(--color-primary);
padding: var(--spacing-sm) var(--spacing-md);
border-radius: var(--border-radius-md);
transition: background-color var(--transition-fast);
}
.button:hover {
background-color: var(--color-primary-dark);
}
```
## Nouvelles Fonctionnalités CSS
### Container Queries
```css
.card-container {
container-type: inline-size;
container-name: card;
}
@container card (min-width: 400px) {
.card {
display: flex;
gap: 1rem;
}
}
```
### :has() Selector
```css
/* Parent avec enfant spécifique */
.form-group:has(:invalid) {
border-color: red;
}
/* Card avec image */
.card:has(img) {
padding-top: 0;
}
```
### Logical Properties
```css
/* Adaptatif au sens de lecture (LTR/RTL) */
.element {
margin-inline-start: 1rem; /* margin-left en LTR */
padding-block: 2rem; /* padding-top + bottom */
border-inline-end: 1px solid; /* border-right en LTR */
}
```
### Fonctions modernes
```css
/* clamp() - valeur responsive */
.title {
font-size: clamp(1.5rem, 5vw, 3rem);
}
/* min() / max() */
.container {
width: min(90%, 1200px);
padding: max(1rem, 5%);
}
/* color-mix() */
.button:hover {
background: color-mix(in srgb, var(--color-primary), black 20%);
}
```
## Cascade et Spécificité
### Ordre de spécificité (du plus faible au plus fort)
1. Sélecteur de type : `div` (0,0,1)
2. Classe, attribut, pseudo-classe : `.card`, `[type]`, `:hover` (0,1,0)
3. ID : `#main` (1,0,0)
4. Style inline : `style=""` (1,0,0,0)
5. `!important` (à éviter)
### Layers CSS
```css
@layer base, components, utilities;
@layer base {
h1 { font-size: 2rem; }
}
@layer components {
.card h1 { font-size: 1.5rem; }
}
@layer utilities {
.text-lg { font-size: 1.25rem !important; }
}
```
## Bonnes Pratiques
### Performance
```css
/* Éviter */
* { box-sizing: border-box; } /* Impacte tout le DOM */
div > * > span { } /* Sélecteur complexe */
/* Préférer */
*, *::before, *::after { box-sizing: border-box; }
.specific-class { }
```
### Maintenabilité
```css
/* Utiliser des noms descriptifs */
.card-header { }
.card-body { }
.card-footer { }
/* Éviter les valeurs magiques */
/* Mauvais */
.element { margin-top: 17px; }
/* Bon */
.element { margin-top: var(--spacing-md); }
```

# Orchestrateur Foundations
## Responsabilité
Coordonner les agents spécialisés dans les fondamentaux du développement web front-end : HTML sémantique, CSS moderne, accessibilité et design responsive.
## Tu NE fais PAS
- ❌ Implémenter directement (déléguer aux agents spécialisés) → agents sous coordination
- ❌ Prendre des décisions d'architecture framework → `frameworks/orchestrator.md`
- ❌ Gérer le JavaScript/TypeScript → `javascript/orchestrator.md`
- ❌ Optimiser les performances → `performance/orchestrator.md`
## Agents sous ma coordination
| Agent | Fichier | Spécialisation |
|-------|---------|----------------|
| HTML Sémantique | `html-semantique.md` | Structure, SEO, métadonnées |
| CSS Moderne | `css-moderne.md` | Grid, Flexbox, variables, cascade |
| Accessibilité | `accessibilite.md` | WCAG, ARIA, tests a11y |
| Responsive Design | `responsive-design.md` | Mobile-first, breakpoints |
## Règles de Routage
```
SI question porte sur [structure HTML, balises, SEO, métadonnées, head]
→ html-semantique.md
SI question porte sur [CSS, Grid, Flexbox, variables CSS, cascade, spécificité]
→ css-moderne.md
SI question porte sur [accessibilité, a11y, WCAG, ARIA, screen reader, contraste]
→ accessibilite.md
SI question porte sur [responsive, mobile, breakpoints, media queries, viewport]
→ responsive-design.md
SI question est transversale
→ Combiner les agents pertinents
```
## Patterns de Composition
### Question structure + accessibilité
```
1. html-semantique.md → Structure de base
2. accessibilite.md → Enrichissement ARIA si nécessaire
3. Vérification cohérence
```
### Question layout responsive
```
1. css-moderne.md → Technique CSS (Grid/Flexbox)
2. responsive-design.md → Adaptation mobile
3. accessibilite.md → Vérification a11y
```
## Escalation
- Vers `frameworks/` si composant framework impliqué
- Vers `performance/` si optimisation CSS requise
- Vers `styling/` si framework CSS (Tailwind, etc.)

# Agent Responsive Design
## Responsabilité
Concevoir et implémenter des interfaces qui s'adaptent à toutes les tailles d'écran, en suivant l'approche mobile-first.
## Tu NE fais PAS
- ❌ Créer les layouts CSS de base (Grid, Flexbox) → `css-moderne.md`
- ❌ Optimiser les performances images (formats, lazy loading) → `performance/`
- ❌ Gérer les frameworks CSS (Tailwind, etc.) → `styling/`
- ❌ Tester l'accessibilité → `accessibilite.md`
## Approche Mobile-First
### Principe
Concevoir d'abord pour les petits écrans, puis enrichir pour les plus grands.
```css
/* Mobile-first : styles de base pour mobile */
.card {
padding: 1rem;
display: flex;
flex-direction: column;
}
/* Puis enrichir pour tablette */
@media (min-width: 768px) {
.card {
flex-direction: row;
padding: 2rem;
}
}
/* Et desktop */
@media (min-width: 1024px) {
.card {
padding: 3rem;
}
}
```
### Avantages
1. **Performance** : CSS minimal chargé sur mobile
2. **Priorité au contenu** : Focus sur l'essentiel
3. **Progressive enhancement** : Enrichissement graduel
4. **Maintenance** : Code plus simple et logique
## Breakpoints Recommandés
### Système de breakpoints
```css
:root {
/* Breakpoints basés sur le contenu, pas les devices */
--breakpoint-sm: 640px; /* Petits écrans */

--breakpoint-lg: 1024px; /* Desktop */
--breakpoint-xl: 1280px; /* Large desktop */
--breakpoint-2xl: 1536px; /* Extra large */
}
/* Usage avec CSS custom media (future spec) */
/* @custom-media --md (min-width: 768px); */
```
### Media queries communes
```css
/* Mobile first - min-width */
@media (min-width: 640px) { /* sm */ }
@media (min-width: 768px) { /* md */ }
@media (min-width: 1024px) { /* lg */ }
@media (min-width: 1280px) { /* xl */ }
/* Combinaisons */
@media (min-width: 768px) and (max-width: 1023px) {
/* Tablette uniquement */
}
/* Orientation */
@media (orientation: landscape) { }
@media (orientation: portrait) { }
/* Préférences utilisateur */
@media (prefers-color-scheme: dark) { }
@media (prefers-reduced-motion: reduce) { }
@media (hover: hover) { /* Device avec hover */ }
@media (hover: none) { /* Touch device */ }
```
## Layouts Responsives
### Container responsive
```css
.container {
width: 100%;
margin-inline: auto;
padding-inline: 1rem;
}
@media (min-width: 640px) {
.container {
max-width: 640px;
}
}
@media (min-width: 768px) {
.container {
max-width: 768px;
padding-inline: 2rem;
}
}
@media (min-width: 1024px) {
.container {
max-width: 1024px;
}
}
@media (min-width: 1280px) {
.container {
max-width: 1200px;
}
}
```
### Grid responsive
```css
/* Auto-responsive avec CSS Grid */
.grid-auto {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(min(100%, 300px), 1fr));
gap: 1rem;
}
/* Grid avec breakpoints explicites */
.grid-responsive {
display: grid;
grid-template-columns: 1fr;
gap: 1rem;
}
@media (min-width: 768px) {
.grid-responsive {
grid-template-columns: repeat(2, 1fr);
}
}
@media (min-width: 1024px) {
.grid-responsive {
grid-template-columns: repeat(3, 1fr);
}
}
```
### Sidebar responsive
```css
.layout {
display: grid;
grid-template-columns: 1fr;
}
@media (min-width: 768px) {
.layout {
grid-template-columns: 250px 1fr;
}
}
/* Ou avec container queries */
.layout-container {
container-type: inline-size;
}
@container (min-width: 700px) {
.layout {
grid-template-columns: 250px 1fr;
}
}
```
## Typographie Responsive
### Fluid typography avec clamp()
```css
:root {
/* Base font size qui s'adapte */
--font-size-base: clamp(1rem, 0.9rem + 0.5vw, 1.125rem);
/* Échelle typographique */
--font-size-sm: clamp(0.875rem, 0.8rem + 0.3vw, 0.9rem);
--font-size-lg: clamp(1.125rem, 1rem + 0.6vw, 1.25rem);
--font-size-xl: clamp(1.25rem, 1rem + 1vw, 1.5rem);
--font-size-2xl: clamp(1.5rem, 1.2rem + 1.5vw, 2rem);
--font-size-3xl: clamp(2rem, 1.5rem + 2vw, 3rem);
--font-size-4xl: clamp(2.5rem, 2rem + 3vw, 4rem);
}
h1 { font-size: var(--font-size-4xl); }
h2 { font-size: var(--font-size-3xl); }
h3 { font-size: var(--font-size-2xl); }
body { font-size: var(--font-size-base); }
```
## Images Responsives
### Élément picture
```html
<picture>
<!-- Format moderne pour navigateurs compatibles -->
<source
srcset="image.avif"
type="image/avif"
>
<source
srcset="image.webp"
type="image/webp"
>
<!-- Art direction : images différentes par taille -->
<source
media="(min-width: 1024px)"
srcset="image-large.jpg"
>
<source
media="(min-width: 768px)"
srcset="image-medium.jpg"
>
<!-- Fallback -->
<img
src="image-small.jpg"
alt="Description de l'image"
loading="lazy"
decoding="async"
>
</picture>
```
### srcset pour résolutions
```html
<img
src="image-400.jpg"
srcset="
image-400.jpg 400w,
image-800.jpg 800w,
image-1200.jpg 1200w
"
sizes="
(min-width: 1024px) 33vw,
(min-width: 768px) 50vw,
100vw
"
alt="Description"
>
```
### CSS pour images fluides
```css
img {
max-width: 100%;
height: auto;
display: block;
}
/* Aspect ratio préservé */
.image-container {
aspect-ratio: 16 / 9;
overflow: hidden;
}
.image-container img {
width: 100%;
height: 100%;
object-fit: cover;
}
```
## Navigation Responsive
### Hamburger menu pattern
```html
<header class="header">
<a href="/" class="logo">Logo</a>
<button
class="menu-toggle"
aria-expanded="false"
aria-controls="main-nav"
aria-label="Menu principal"
>
<span class="hamburger"></span>
</button>
<nav id="main-nav" class="nav" aria-label="Navigation principale">
<ul class="nav-list">
<li><a href="/">Accueil</a></li>
<li><a href="/about">À propos</a></li>
<li><a href="/contact">Contact</a></li>
</ul>
</nav>
</header>
```
```css
.header {
display: flex;
justify-content: space-between;
align-items: center;
padding: 1rem;
}
/* Mobile : menu caché */
.nav {
position: fixed;
inset: 0;
background: white;
transform: translateX(-100%);
transition: transform 0.3s ease;
}
.nav.is-open {
transform: translateX(0);
}
.menu-toggle {
display: flex;
}
/* Desktop : menu visible */
@media (min-width: 768px) {
.nav {
position: static;
transform: none;
background: transparent;
}
.nav-list {
display: flex;
gap: 2rem;
}
.menu-toggle {
display: none;
}
}
```
## Touch Targets
```css
/* Taille minimum pour touch (44x44px selon WCAG) */
.button,
.link,
.interactive {
min-height: 44px;
min-width: 44px;
padding: 12px 16px;
}
/* Espacement entre éléments touchables */
.nav-list {
gap: 8px;
}
/* Désactiver hover sur touch */
@media (hover: none) {
.button:hover {
/* Pas d'effet hover sur touch */
background: inherit;
}
}
/* Activer hover uniquement si disponible */
@media (hover: hover) {
.button:hover {
background: var(--color-primary-dark);
}
}
```

# Agent Component Patterns
## Responsabilité
Maîtriser les patterns de composants réutilisables applicables à tous les frameworks front-end.
## Tu NE fais PAS
- ❌ Implémenter les spécificités React (hooks, Context) → `react-expert.md` ou skill `react-expert`
- ❌ Implémenter les spécificités Vue (Composition API, Pinia) → `vue-expert.md`
- ❌ Gérer le state management global → `state-management/`
- ❌ Tester les composants → `testing/component-testing.md`
## Compound Components
### Concept
Composants qui fonctionnent ensemble pour partager un état implicite.
```tsx
// Usage
<Tabs defaultValue="tab1">
<Tabs.List>
<Tabs.Trigger value="tab1">Tab 1</Tabs.Trigger>
<Tabs.Trigger value="tab2">Tab 2</Tabs.Trigger>
</Tabs.List>
<Tabs.Content value="tab1">Contenu 1</Tabs.Content>
<Tabs.Content value="tab2">Contenu 2</Tabs.Content>
</Tabs>
```
### Implémentation React
```tsx
import { createContext, useContext, useState, ReactNode } from 'react';
interface TabsContextType {
activeTab: string;
setActiveTab: (value: string) => void;
}
const TabsContext = createContext<TabsContextType | null>(null);
function useTabs() {
const context = useContext(TabsContext);
if (!context) {
throw new Error('Tabs components must be used within a Tabs');
}
return context;
}
interface TabsProps {
defaultValue: string;
children: ReactNode;
}
function Tabs({ defaultValue, children }: TabsProps) {
const [activeTab, setActiveTab] = useState(defaultValue);
return (
<TabsContext.Provider value={{ activeTab, setActiveTab }}>
<div className="tabs">{children}</div>
</TabsContext.Provider>
);
}
function TabsList({ children }: { children: ReactNode }) {
return <div role="tablist" className="tabs-list">{children}</div>;
}
interface TabsTriggerProps {
value: string;
children: ReactNode;
}
function TabsTrigger({ value, children }: TabsTriggerProps) {
const { activeTab, setActiveTab } = useTabs();
const isActive = activeTab === value;
return (
<button
role="tab"
aria-selected={isActive}
onClick={() => setActiveTab(value)}
className={`tab-trigger ${isActive ? 'active' : ''}`}
>
{children}
</button>
);
}
interface TabsContentProps {
value: string;
children: ReactNode;
}
function TabsContent({ value, children }: TabsContentProps) {
const { activeTab } = useTabs();
if (activeTab !== value) return null;
return (
<div role="tabpanel" className="tab-content">
{children}
</div>
);
}
// Attacher les sous-composants
Tabs.List = TabsList;
Tabs.Trigger = TabsTrigger;
Tabs.Content = TabsContent;
export { Tabs };
```
## Render Props
### Concept
Passer une fonction en prop pour contrôler le rendu.
```tsx
// Usage
<MouseTracker>
{({ x, y }) => (
<div>Position: {x}, {y}</div>
)}
</MouseTracker>
```
### Implémentation
```tsx
import { useState, useEffect, ReactNode } from 'react';
interface MousePosition {
x: number;
y: number;
}
interface MouseTrackerProps {
children: (position: MousePosition) => ReactNode;
}
function MouseTracker({ children }: MouseTrackerProps) {
const [position, setPosition] = useState<MousePosition>({ x: 0, y: 0 });
useEffect(() => {
const handleMouseMove = (e: MouseEvent) => {
setPosition({ x: e.clientX, y: e.clientY });
};
window.addEventListener('mousemove', handleMouseMove);
return () => window.removeEventListener('mousemove', handleMouseMove);
}, []);
return <>{children(position)}</>;
}
// Variante avec prop render
interface MouseTrackerRenderProps {
render: (position: MousePosition) => ReactNode;
}
function MouseTrackerAlt({ render }: MouseTrackerRenderProps) {
const [position, setPosition] = useState<MousePosition>({ x: 0, y: 0 });
// ... même logique
return <>{render(position)}</>;
}
```
## Headless Components (Renderless)
### Concept
Composants qui gèrent la logique sans imposer de markup.
```tsx
// Usage
<Toggle>
{({ isOn, toggle }) => (
<button onClick={toggle}>
{isOn ? 'ON' : 'OFF'}
</button>
)}
</Toggle>
```
### Implémentation Hook (React)
```tsx
// Hook headless
function useToggle(initialState = false) {
const [isOn, setIsOn] = useState(initialState);
const toggle = useCallback(() => setIsOn((prev) => !prev), []);
const setOn = useCallback(() => setIsOn(true), []);
const setOff = useCallback(() => setIsOn(false), []);
return { isOn, toggle, setOn, setOff };
}
// Usage avec hook
function CustomToggle() {
const { isOn, toggle } = useToggle();
return (
<div className="custom-toggle" onClick={toggle}>
<span className={isOn ? 'active' : ''}>Toggle</span>
</div>
);
}
// Ou avec composant render prop
interface ToggleProps {
children: (state: ReturnType<typeof useToggle>) => ReactNode;
}
function Toggle({ children }: ToggleProps) {
const state = useToggle();
return <>{children(state)}</>;
}
```
### Headless Dropdown
```tsx
function useDropdown<T>() {
const [isOpen, setIsOpen] = useState(false);
const [selected, setSelected] = useState<T | null>(null);
const dropdownRef = useRef<HTMLDivElement>(null);
const open = () => setIsOpen(true);
const close = () => setIsOpen(false);
const toggle = () => setIsOpen((prev) => !prev);
const select = (item: T) => {
setSelected(item);
close();
};
// Fermer au clic externe
useEffect(() => {
const handleClickOutside = (e: MouseEvent) => {
if (dropdownRef.current && !dropdownRef.current.contains(e.target as Node)) {
close();
}
};
document.addEventListener('mousedown', handleClickOutside);
return () => document.removeEventListener('mousedown', handleClickOutside);
}, []);
// Fermer avec Escape
useEffect(() => {
const handleEscape = (e: KeyboardEvent) => {
if (e.key === 'Escape') close();
};
document.addEventListener('keydown', handleEscape);
return () => document.removeEventListener('keydown', handleEscape);
}, []);
return {
isOpen,
selected,
dropdownRef,
open,
close,
toggle,
select,
};
}
```
## Controlled vs Uncontrolled
### Controlled Component
```tsx
interface ControlledInputProps {
value: string;
onChange: (value: string) => void;
}
function ControlledInput({ value, onChange }: ControlledInputProps) {
return (
<input
value={value}
onChange={(e) => onChange(e.target.value)}
/>
);
}
// Usage - le parent gère l'état
function Form() {
const [name, setName] = useState('');
return <ControlledInput value={name} onChange={setName} />;
}
```
### Uncontrolled Component
```tsx
import { forwardRef, useImperativeHandle, useRef } from 'react';
interface UncontrolledInputRef {
getValue: () => string;
focus: () => void;
}
const UncontrolledInput = forwardRef<UncontrolledInputRef>((props, ref) => {
const inputRef = useRef<HTMLInputElement>(null);
useImperativeHandle(ref, () => ({
getValue: () => inputRef.current?.value || '',
focus: () => inputRef.current?.focus(),
}));
return <input ref={inputRef} defaultValue="" />;
});
// Usage - accès via ref
function Form() {
const inputRef = useRef<UncontrolledInputRef>(null);
const handleSubmit = () => {
const value = inputRef.current?.getValue();
console.log(value);
};
return (
<>
<UncontrolledInput ref={inputRef} />
<button onClick={handleSubmit}>Submit</button>
</>
);
}
```
### Pattern hybride (contrôlé optionnel)
```tsx
interface FlexibleInputProps {
value?: string;
defaultValue?: string;
onChange?: (value: string) => void;
}
function FlexibleInput({ value, defaultValue = '', onChange }: FlexibleInputProps) {
const isControlled = value !== undefined;
const [internalValue, setInternalValue] = useState(defaultValue);
const currentValue = isControlled ? value : internalValue;
const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
const newValue = e.target.value;
if (!isControlled) {
setInternalValue(newValue);
}
onChange?.(newValue);
};
return <input value={currentValue} onChange={handleChange} />;
}
// Usage contrôlé
<FlexibleInput value={name} onChange={setName} />
// Usage non-contrôlé
<FlexibleInput defaultValue="John" onChange={console.log} />
```
## Slot Pattern (Vue-like en React)
```tsx
interface SlotProps {
header?: ReactNode;
footer?: ReactNode;
children: ReactNode;
}
function Card({ header, footer, children }: SlotProps) {
return (
<div className="card">
{header && <header className="card-header">{header}</header>}
<main className="card-body">{children}</main>
{footer && <footer className="card-footer">{footer}</footer>}
</div>
);
}
// Usage
<Card
header={<h2>Titre</h2>}
footer={<button>Action</button>}
>
<p>Contenu principal</p>
</Card>
```
## Provider Pattern
```tsx
// Créer un provider réutilisable
function createProvider<T>(
defaultValue: T,
displayName: string
) {
const Context = createContext<T | undefined>(undefined);
function Provider({
value,
children,
}: {
value: T;
children: ReactNode;
}) {
return <Context.Provider value={value}>{children}</Context.Provider>;
}
function useContextValue() {
const context = useContext(Context);
if (context === undefined) {
throw new Error(`use${displayName} must be used within ${displayName}Provider`);
}
return context;
}
Provider.displayName = `${displayName}Provider`;
return [Provider, useContextValue] as const;
}
// Usage
const [ThemeProvider, useTheme] = createProvider<Theme>(
{ mode: 'light' },
'Theme'
);
```
## Composition over Inheritance
```tsx
// ❌ Éviter l'héritage
class Button extends BaseButton {
render() { /* ... */ }
}
// ✅ Préférer la composition
interface ButtonProps extends React.ButtonHTMLAttributes<HTMLButtonElement> {
variant?: 'primary' | 'secondary';
size?: 'sm' | 'md' | 'lg';
leftIcon?: ReactNode;
rightIcon?: ReactNode;
}
function Button({
variant = 'primary',
size = 'md',
leftIcon,
rightIcon,
children,
className,
...props
}: ButtonProps) {
return (
<button
className={cn('btn', `btn-${variant}`, `btn-${size}`, className)}
{...props}
>
{leftIcon && <span className="btn-icon-left">{leftIcon}</span>}
{children}
{rightIcon && <span className="btn-icon-right">{rightIcon}</span>}
</button>
);
}
// Variantes via composition
function IconButton(props: Omit<ButtonProps, 'children'> & { icon: ReactNode }) {
return <Button {...props}>{props.icon}</Button>;
}
```

## Server Components vs Client Components
### Server Component (défaut)
```tsx
// app/users/page.tsx
// Par défaut, tous les composants sont Server Components
import { db } from '@/lib/db';
// Peut directement accéder à la DB
export default async function UsersPage() {
const users = await db.user.findMany();
return (
<ul>
{users.map((user) => (
<li key={user.id}>{user.name}</li>
))}
</ul>
);
}
```
### Client Component
```tsx
'use client';
// Nécessaire pour : hooks React, event handlers, browser APIs
import { useState } from 'react';
export default function Counter() {
const [count, setCount] = useState(0);
return (
<button onClick={() => setCount(count + 1)}>
Count: {count}
</button>
);
}
```
### Pattern de composition
```tsx
// app/dashboard/page.tsx (Server Component)
import { db } from '@/lib/db';
import { InteractiveChart } from '@/components/InteractiveChart';
export default async function DashboardPage() {
const data = await db.analytics.getStats();
return (
<div>
<h1>Dashboard</h1>
{/* Passer les données serveur au Client Component */}
<InteractiveChart data={data} />
</div>
);
}
// components/InteractiveChart.tsx
'use client';
export function InteractiveChart({ data }: { data: Stats }) {
// Interactivité côté client avec données serveur
return <Chart data={data} />;
}
```
## Data Fetching
### Fetch avec cache
```tsx
// Par défaut, fetch est caché et dédupliqué
async function getUser(id: string) {
const res = await fetch(`https://api.example.com/users/${id}`);
return res.json();
}
// Options de cache
await fetch(url, { cache: 'force-cache' }); // Défaut
await fetch(url, { cache: 'no-store' }); // Pas de cache
await fetch(url, { next: { revalidate: 3600 } }); // ISR: revalider chaque heure
await fetch(url, { next: { tags: ['users'] } }); // Tag pour invalidation
```
### generateStaticParams (SSG)
```tsx
// app/blog/[slug]/page.tsx
export async function generateStaticParams() {
const posts = await getPosts();
return posts.map((post) => ({
slug: post.slug,
}));
}
export default async function BlogPost({
params,
}: {
params: { slug: string };
}) {
const post = await getPost(params.slug);
return <article>{post.content}</article>;
}
```
### generateMetadata
```tsx
import type { Metadata } from 'next';
// Metadata statique
export const metadata: Metadata = {
title: 'Mon Site',
description: 'Description du site',
};
// Metadata dynamique
export async function generateMetadata({
params,
}: {
params: { slug: string };
}): Promise<Metadata> {
const post = await getPost(params.slug);
return {
title: post.title,
description: post.excerpt,
openGraph: {
images: [post.coverImage],
},
};
}
```
## Layouts et Templates
### Root Layout (obligatoire)
```tsx
// app/layout.tsx
import { Inter } from 'next/font/google';
import './globals.css';
const inter = Inter({ subsets: ['latin'] });
export const metadata = {
title: {
template: '%s | Mon Site',
default: 'Mon Site',
},
};
export default function RootLayout({
children,
}: {
children: React.ReactNode;
}) {
return (
<html lang="fr">
<body className={inter.className}>
<header>Navigation</header>
<main>{children}</main>
<footer>Footer</footer>
</body>
</html>
);
}
```
### Nested Layout
```tsx
// app/dashboard/layout.tsx
export default function DashboardLayout({
children,
}: {
children: React.ReactNode;
}) {
return (
<div className="dashboard">
<aside>Sidebar</aside>
<section>{children}</section>
</div>
);
}
```
### Template (re-render à chaque navigation)
```tsx
// app/dashboard/template.tsx
export default function Template({ children }: { children: React.ReactNode }) {
// Recrée l'état à chaque navigation
return <div className="animate-in">{children}</div>;
}
```
## Loading et Error States
### Loading UI
```tsx
// app/dashboard/loading.tsx
export default function Loading() {
return <div className="skeleton">Chargement...</div>;
}
// Avec Suspense manuel
import { Suspense } from 'react';
export default function Page() {
return (
<Suspense fallback={<LoadingSkeleton />}>
<SlowComponent />
</Suspense>
);
}
```
### Error Handling
```tsx
// app/dashboard/error.tsx
'use client';
export default function Error({
error,
reset,
}: {
error: Error & { digest?: string };
reset: () => void;
}) {
return (
<div>
<h2>Une erreur est survenue</h2>
<p>{error.message}</p>
<button onClick={() => reset()}>Réessayer</button>
</div>
);
}
```
### Not Found
```tsx
// app/not-found.tsx
export default function NotFound() {
return (
<div>
<h2>404 - Page non trouvée</h2>
<Link href="/">Retour à l'accueil</Link>
</div>
);
}
// Trigger manuel
import { notFound } from 'next/navigation';
export default async function Page({ params }: { params: { id: string } }) {
const item = await getItem(params.id);
if (!item) notFound();
return <div>{item.name}</div>;
}
```
## API Routes (Route Handlers)
```tsx
// app/api/users/route.ts
import { NextRequest, NextResponse } from 'next/server';
export async function GET(request: NextRequest) {
const searchParams = request.nextUrl.searchParams;
const page = searchParams.get('page') || '1';
const users = await db.user.findMany({
skip: (parseInt(page) - 1) * 10,
take: 10,
});
return NextResponse.json(users);
}
export async function POST(request: NextRequest) {
const body = await request.json();
const user = await db.user.create({
data: body,
});
return NextResponse.json(user, { status: 201 });
}
// app/api/users/[id]/route.ts
export async function GET(
request: NextRequest,
{ params }: { params: { id: string } }
) {
const user = await db.user.findUnique({
where: { id: params.id },
});
if (!user) {
return NextResponse.json(
{ error: 'User not found' },
{ status: 404 }
);
}
return NextResponse.json(user);
}
export async function DELETE(
request: NextRequest,
{ params }: { params: { id: string } }
) {
await db.user.delete({
where: { id: params.id },
});
return new NextResponse(null, { status: 204 });
}
```
## Server Actions
```tsx
// app/actions.ts
'use server';
import { revalidatePath, revalidateTag } from 'next/cache';
import { redirect } from 'next/navigation';
export async function createPost(formData: FormData) {
const title = formData.get('title') as string;
const content = formData.get('content') as string;
const post = await db.post.create({
data: { title, content },
});
revalidatePath('/posts');
redirect(`/posts/${post.id}`);
}
export async function deletePost(id: string) {
await db.post.delete({ where: { id } });
revalidateTag('posts');
}
```
```tsx
// app/posts/new/page.tsx
import { createPost } from '@/app/actions';
export default function NewPostPage() {
return (
<form action={createPost}>
<input name="title" placeholder="Titre" required />
<textarea name="content" placeholder="Contenu" required />
<button type="submit">Créer</button>
</form>
);
}
```
## Middleware
```tsx
// middleware.ts (à la racine)
import { NextResponse } from 'next/server';
import type { NextRequest } from 'next/server';
export function middleware(request: NextRequest) {
// Vérifier l'authentification
const token = request.cookies.get('token');
if (!token && request.nextUrl.pathname.startsWith('/dashboard')) {
return NextResponse.redirect(new URL('/login', request.url));
}
// Ajouter des headers
const response = NextResponse.next();
response.headers.set('x-custom-header', 'value');
return response;
}
export const config = {
matcher: ['/dashboard/:path*', '/api/:path*'],
};
```
## Optimisations
### Image Component
```tsx
import Image from 'next/image';
export default function Avatar() {
return (
<Image
src="/avatar.jpg"
alt="Avatar"
width={100}
height={100}
priority // Pour LCP
placeholder="blur"
blurDataURL="data:image/jpeg;base64,..."
/>
);
}
// Image responsive
<Image
src="/hero.jpg"
alt="Hero"
fill
sizes="(max-width: 768px) 100vw, 50vw"
className="object-cover"
/>
```
### Link Component
```tsx
import Link from 'next/link';
// Prefetch automatique en viewport
<Link href="/about">À propos</Link>
// Désactiver prefetch
<Link href="/large-page" prefetch={false}>Large Page</Link>
// Navigation programmatique
'use client';
import { useRouter } from 'next/navigation';
export function LogoutButton() {
const router = useRouter();
async function logout() {
await signOut();
router.push('/login');
router.refresh(); // Rafraîchir les Server Components
}
return <button onClick={logout}>Déconnexion</button>;
}
```

# Orchestrateur Frameworks
## Responsabilité
Coordonner les agents spécialisés dans les frameworks JavaScript front-end modernes.
## Tu NE fais PAS
- ❌ Implémenter directement (déléguer aux agents spécialisés) → agents sous coordination
- ❌ Gérer le JavaScript pur (ES6+, async, modules) → `javascript/orchestrator.md`
- ❌ Gérer le state management avancé → `state-management/orchestrator.md`
- ❌ Tester les composants → `testing/orchestrator.md`
## Agents sous ma coordination
| Agent | Fichier | Spécialisation |
|-------|---------|----------------|
| React Expert | `react-expert.md` | Composants, hooks, patterns React |
| Vue Expert | `vue-expert.md` | Composition API, Pinia, Vue patterns |
| Next.js Expert | `nextjs-expert.md` | SSR, SSG, App Router |
| Nuxt Expert | `nuxt-expert.md` | Nuxt 3, Nitro, auto-imports |
| Component Patterns | `component-patterns.md` | Patterns communs tous frameworks |
## Règles de Routage
```
SI question porte sur [React, hooks, useState, useEffect, JSX, React Router]
→ react-expert.md
SI question porte sur [Vue, Composition API, ref, reactive, Pinia, Vue Router]
→ vue-expert.md
SI question porte sur [Next.js, App Router, SSR, SSG, API Routes, Server Components]
→ nextjs-expert.md
SI question porte sur [Nuxt, Nuxt 3, Nitro, useFetch, useAsyncData]
→ nuxt-expert.md
SI question porte sur [patterns, HOC, render props, compound components, slots]
→ component-patterns.md
SI question est transversale ou comparative
→ Combiner les experts pertinents
```
## Patterns de Composition
### Migration React → Vue
```
1. react-expert.md → Identifier les patterns React actuels
2. vue-expert.md → Équivalents Vue
3. component-patterns.md → Patterns communs
```
### Choix de framework
```
1. Analyser les besoins projet
2. Consulter chaque expert sur les forces/faiblesses
3. Recommandation basée sur le contexte
```

> **Note** : Ce fichier a été simplifié. Le contenu détaillé se trouve dans le skill dédié `react-expert`.
## Quand utiliser cet agent
- Questions rapides sur React
- Intégration avec d'autres préoccupations frontend
- Vue d'ensemble des patterns React
## Quand utiliser le skill react-expert
Pour toute question approfondie, invoquer directement le skill `react-expert` qui contient **28 agents spécialisés** :
| Domaine | Agents | Spécialités |
|---------|--------|-------------|
| `hooks/` | 5 | useState, useEffect, useRef, custom hooks |

## Patterns Essentiels (Résumé)
### Composant fonctionnel
```tsx
interface Props {
userId: string;
onSelect?: (id: string) => void;
}
export function UserCard({ userId, onSelect }: Props) {
const { data: user, isLoading } = useUser(userId);
if (isLoading) return <Skeleton />;
if (!user) return <NotFound />;
return (
<article onClick={() => onSelect?.(userId)}>
<h2>{user.name}</h2>
</article>
);
}
```
### Custom hook
```tsx
function useLocalStorage<T>(key: string, initialValue: T) {
const [value, setValue] = useState<T>(() => {
const item = localStorage.getItem(key);
return item ? JSON.parse(item) : initialValue;
});
useEffect(() => {
localStorage.setItem(key, JSON.stringify(value));
}, [key, value]);
return [value, setValue] as const;
}
```
## Tu NE fais PAS
- ❌ Gérer Next.js spécifiquement (App Router, Server Components) → `nextjs-expert.md`
- ❌ Implémenter le state global avancé (Redux, Zustand patterns complexes) → skill `react-expert/state/`
- ❌ Tester les composants et hooks → skill `react-expert/testing/`
- ❌ Optimiser les performances avancées → skill `react-expert/performance/`
## Points d'Escalade
## Délégation
→ **Pour une couverture complète de React**, invoquer le skill : `react-expert`
## Mots-clés de routage
`React`, `hooks`, `useState`, `useEffect`, `composant`, `JSX`, `props`
## Livrables
| Livrable | Description |
|----------|-------------|
| Composants React | Code des composants fonctionnels avec hooks et TypeScript |
| Custom hooks | Hooks réutilisables pour la logique métier et state management |
| Documentation composants | Props, exemples d'usage et patterns d'intégration |

# Agent Vue Expert
## Responsabilité
Maîtriser Vue 3 avec la Composition API pour créer des applications réactives et maintenables.
## Tu NE fais PAS
- ❌ Implémenter Nuxt.js spécifiquement (SSR, modules) → Déléguer à un expert Nuxt si disponible
- ❌ Gérer le state Pinia avancé (patterns complexes, persistence) → `state-management/`
- ❌ Tester les composants Vue → `testing/component-testing.md`
- ❌ Optimiser les performances avancées → `performance/`
## Composants avec Script Setup
### Structure de base
```vue
<script setup lang="ts">
import { ref, computed, onMounted } from 'vue';
import type { User } from '@/types';
// Props avec valeurs par défaut
interface Props {
userId: string;
showAvatar?: boolean;
}
const props = withDefaults(defineProps<Props>(), {
showAvatar: true
});
// Emits typés
const emit = defineEmits<{
select: [id: string];
update: [user: User];
}>();
// State réactif
const user = ref<User | null>(null);
const isLoading = ref(true);
// Computed
const fullName = computed(() => {
if (!user.value) return '';
return `${user.value.firstName} ${user.value.lastName}`;
});
// Methods
function handleSelect() {
if (user.value) {
emit('select', user.value.id);
}
}
// Lifecycle
onMounted(async () => {
user.value = await fetchUser(props.userId);
isLoading.value = false;
});
</script>
<template>
<div v-if="isLoading" class="skeleton" />
<article v-else-if="user" class="user-card" @click="handleSelect">
<img v-if="showAvatar" :src="user.avatar" :alt="fullName" />
<h2>{{ fullName }}</h2>
<p>{{ user.email }}</p>
</article>
</template>
<style scoped>
.user-card {
padding: 1rem;
border-radius: 8px;
cursor: pointer;
}
</style>
```
## Réactivité
### ref vs reactive
```vue
<script setup lang="ts">
import { ref, reactive, toRefs } from 'vue';
// ref - pour primitives et valeurs simples
const count = ref(0);
const message = ref('Hello');
count.value++; // Accès avec .value en JS
// reactive - pour objets
const state = reactive({
count: 0,
items: [] as string[]
});
state.count++; // Accès direct
// Destructuration avec toRefs
const { count: countRef, items } = toRefs(state);
// ref pour objets (recommandé pour la cohérence)
const user = ref<User | null>(null);
user.value = { name: 'John' };
</script>
<template>
<!-- Dans le template, pas besoin de .value -->
<p>Count: {{ count }}</p>
<p>State count: {{ state.count }}</p>
</template>
```
### Computed et Watch
```vue
<script setup lang="ts">
import { ref, computed, watch, watchEffect } from 'vue';
const firstName = ref('John');
const lastName = ref('Doe');
// Computed - réactif, mémorisé
const fullName = computed(() => `${firstName.value} ${lastName.value}`);
// Computed writable
const fullNameWritable = computed({
get: () => `${firstName.value} ${lastName.value}`,
set: (value: string) => {
const [first, last] = value.split(' ');
firstName.value = first;
lastName.value = last || '';
}
});
// Watch - observer une source spécifique
watch(firstName, (newValue, oldValue) => {
console.log(`firstName changed from ${oldValue} to ${newValue}`);
});
// Watch multiple sources
watch([firstName, lastName], ([newFirst, newLast], [oldFirst, oldLast]) => {
console.log('Name changed');
});
// Watch avec options
watch(
() => user.value?.id,
async (newId) => {
if (newId) {
await fetchUserData(newId);
}
},
{ immediate: true, deep: false }
);
// watchEffect - exécute automatiquement quand les dépendances changent
watchEffect(() => {
console.log(`Full name is: ${fullName.value}`);
});
// watchEffect avec cleanup
watchEffect((onCleanup) => {
const controller = new AbortController();
fetchData(controller.signal);
onCleanup(() => controller.abort());
});
</script>
```
## Lifecycle Hooks
```vue
<script setup lang="ts">
import {
onBeforeMount,
onMounted,
onBeforeUpdate,
onUpdated,
onBeforeUnmount,
onUnmounted,
onActivated,
onDeactivated
} from 'vue';
onBeforeMount(() => {
// Avant le premier rendu DOM
});
onMounted(() => {
// Après le premier rendu DOM
// Accès au DOM possible ici
});
onBeforeUpdate(() => {
// Avant une mise à jour du DOM
});
onUpdated(() => {
// Après une mise à jour du DOM
});
onBeforeUnmount(() => {
// Avant destruction du composant
// Cleanup subscriptions, timers, etc.
});
onUnmounted(() => {
// Après destruction du composant
});
// Pour les composants dans <KeepAlive>
onActivated(() => {
// Composant activé (visible)
});
onDeactivated(() => {
// Composant désactivé (caché)
});
</script>
```
## Template Refs
```vue
<script setup lang="ts">
import { ref, onMounted } from 'vue';
// Ref au DOM element
const inputRef = ref<HTMLInputElement | null>(null);
// Ref au composant enfant
const childRef = ref<InstanceType<typeof ChildComponent> | null>(null);
onMounted(() => {
inputRef.value?.focus();
childRef.value?.someMethod();
});
// Expose des méthodes/propriétés au parent
defineExpose({
focus: () => inputRef.value?.focus(),
getValue: () => inputRef.value?.value
});
</script>
<template>
<input ref="inputRef" type="text" />
<ChildComponent ref="childRef" />
</template>
```
## Composables (Hooks Vue)
### Pattern de base
```typescript
// composables/useLocalStorage.ts
import { ref, watch } from 'vue';
export function useLocalStorage<T>(key: string, defaultValue: T) {
const stored = localStorage.getItem(key);
const data = ref<T>(stored ? JSON.parse(stored) : defaultValue);
watch(
data,
(newValue) => {
localStorage.setItem(key, JSON.stringify(newValue));
},
{ deep: true }
);
return data;
}
// Usage
const theme = useLocalStorage('theme', 'light');
```
### useFetch composable
```typescript
// composables/useFetch.ts
import { ref, watchEffect, type Ref } from 'vue';
interface UseFetchReturn<T> {
data: Ref<T | null>;
error: Ref<Error | null>;
isLoading: Ref<boolean>;
refetch: () => Promise<void>;
}
export function useFetch<T>(url: Ref<string> | string): UseFetchReturn<T> {
const data = ref<T | null>(null) as Ref<T | null>;
const error = ref<Error | null>(null);
const isLoading = ref(false);
async function fetchData() {
isLoading.value = true;
error.value = null;
try {
const urlValue = typeof url === 'string' ? url : url.value;
const response = await fetch(urlValue);
if (!response.ok) throw new Error('Fetch failed');
data.value = await response.json();
} catch (err) {
error.value = err instanceof Error ? err : new Error('Unknown error');
} finally {
isLoading.value = false;
}
}
watchEffect(() => {
fetchData();
});
return { data, error, isLoading, refetch: fetchData };
}
```
### useToggle composable
```typescript
// composables/useToggle.ts
import { ref } from 'vue';
export function useToggle(initialValue = false) {
const state = ref(initialValue);
function toggle() {
state.value = !state.value;
}
function setTrue() {
state.value = true;
}
function setFalse() {
state.value = false;
}
return {
state,
toggle,
setTrue,
setFalse
};
}
// Usage
const { state: isOpen, toggle: toggleModal } = useToggle();
```
## Slots
```vue

<ul>
<slot
v-for="(item, index) in items"
:key="item.id"
name="item"
:item="item"
:index="index"
/>
</ul>
</div>
</template>
```
## Provide/Inject
```vue
<!-- Parent (Provider) -->
<script setup lang="ts">
import { provide, ref } from 'vue';
import type { InjectionKey } from 'vue';
interface ThemeContext {
theme: Ref<'light' | 'dark'>;
toggleTheme: () => void;
}
export const ThemeKey: InjectionKey<ThemeContext> = Symbol('theme');
const theme = ref<'light' | 'dark'>('light');
function toggleTheme() {
theme.value = theme.value === 'light' ? 'dark' : 'light';
}
provide(ThemeKey, { theme, toggleTheme });
</script>

# Agent API Integration
## Responsabilité
Intégrer efficacement les APIs externes et internes dans les applications front-end.
## Tu NE fais PAS
- ❌ Créer les APIs backend (Express, Fastify, serveurs) → skill `backend-developer`
- ❌ Gérer le state global des données (caching, synchronisation) → `state-management/server-state.md`
- ❌ Typer les réponses API (interfaces, types) → `typescript.md`
- ❌ Tester les appels API → `testing/`
## Fetch API
### Requêtes de base
```javascript
// GET simple
const response = await fetch('/api/users');
const users = await response.json();
// POST avec JSON
const response = await fetch('/api/users', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
name: 'John',
email: 'john@example.com'
})
});
// PUT
await fetch(`/api/users/${id}`, {
method: 'PUT',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(userData)
});
// DELETE
await fetch(`/api/users/${id}`, {
method: 'DELETE'
});
// PATCH
await fetch(`/api/users/${id}`, {
method: 'PATCH',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ name: 'New Name' })
});
```
### Gestion des erreurs
```javascript
async function fetchWithErrorHandling(url, options = {}) {
try {
const response = await fetch(url, options);
// Vérifier le status HTTP
if (!response.ok) {
// Essayer de parser l'erreur du serveur
let errorMessage;
try {
const errorData = await response.json();
errorMessage = errorData.message || errorData.error;
} catch {
errorMessage = response.statusText;
}
throw new APIError(errorMessage, response.status);
}
return await response.json();
} catch (error) {
if (error instanceof APIError) {
throw error;
}
// Erreur réseau
if (error.name === 'TypeError') {
throw new NetworkError('Network request failed');
}
throw error;
}
}
// Classes d'erreur personnalisées
class APIError extends Error {
constructor(message, status) {
super(message);
this.name = 'APIError';
this.status = status;
}
}
class NetworkError extends Error {
constructor(message) {
super(message);
this.name = 'NetworkError';
}
}
```
### Options avancées
```javascript
// Timeout avec AbortController
async function fetchWithTimeout(url, options = {}, timeout = 5000) {
const controller = new AbortController();
const timeoutId = setTimeout(() => controller.abort(), timeout);
try {
const response = await fetch(url, {
...options,
signal: controller.signal
});
clearTimeout(timeoutId);
return response;
} catch (error) {
clearTimeout(timeoutId);
if (error.name === 'AbortError') {
throw new Error('Request timeout');
}
throw error;
}
}
// Annulation manuelle
const controller = new AbortController();
// Dans un composant React
useEffect(() => {
const controller = new AbortController();
fetch('/api/data', { signal: controller.signal })
.then((res) => res.json())
.then(setData)
.catch((err) => {
if (err.name !== 'AbortError') {
setError(err);
}
});
return () => controller.abort();
}, []);
```
## Client API Wrapper
```javascript
class APIClient {
constructor(baseURL, options = {}) {
this.baseURL = baseURL;
this.defaultHeaders = {
'Content-Type': 'application/json',
...options.headers
};
}
async request(endpoint, options = {}) {
const url = `${this.baseURL}${endpoint}`;
const config = {
...options,
headers: {
...this.defaultHeaders,
...options.headers
}
};
// Ajouter le token si présent
const token = this.getToken();
if (token) {
config.headers.Authorization = `Bearer ${token}`;
}
const response = await fetch(url, config);
if (!response.ok) {
await this.handleError(response);
}
// Gérer les réponses vides (204 No Content)
if (response.status === 204) {
return null;
}
return response.json();
}
async get(endpoint, params = {}) {
const queryString = new URLSearchParams(params).toString();
const url = queryString ? `${endpoint}?${queryString}` : endpoint;
return this.request(url);
}
async post(endpoint, data) {
return this.request(endpoint, {
method: 'POST',
body: JSON.stringify(data)
});
}
async put(endpoint, data) {
return this.request(endpoint, {
method: 'PUT',
body: JSON.stringify(data)
});
}
async patch(endpoint, data) {
return this.request(endpoint, {
method: 'PATCH',
body: JSON.stringify(data)
});
}
async delete(endpoint) {
return this.request(endpoint, { method: 'DELETE' });
}
getToken() {
return localStorage.getItem('auth_token');
}
setToken(token) {
localStorage.setItem('auth_token', token);
}
async handleError(response) {
const error = await response.json().catch(() => ({}));
if (response.status === 401) {
this.setToken(null);
window.location.href = '/login';
}
throw new APIError(error.message || 'Request failed', response.status);
}
}
// Usage
const api = new APIClient('https://api.example.com');
const users = await api.get('/users', { page: 1, limit: 10 });
const newUser = await api.post('/users', { name: 'John' });
await api.delete(`/users/${id}`);
```
## Upload de fichiers
```javascript
// Upload simple
async function uploadFile(file) {
const formData = new FormData();
formData.append('file', file);
formData.append('description', 'My file');
const response = await fetch('/api/upload', {
method: 'POST',
body: formData // Pas de Content-Type header (auto avec boundary)
});
return response.json();
}
// Upload avec progression
async function uploadWithProgress(file, onProgress) {
return new Promise((resolve, reject) => {
const xhr = new XMLHttpRequest();
xhr.upload.addEventListener('progress', (event) => {
if (event.lengthComputable) {
const percent = Math.round((event.loaded / event.total) * 100);
onProgress(percent);
}
});
xhr.addEventListener('load', () => {
if (xhr.status >= 200 && xhr.status < 300) {
resolve(JSON.parse(xhr.responseText));
} else {
reject(new Error(`Upload failed: ${xhr.status}`));
}
});
xhr.addEventListener('error', () => reject(new Error('Upload failed')));
const formData = new FormData();
formData.append('file', file);
xhr.open('POST', '/api/upload');
xhr.send(formData);
});
}
// Upload multiple
async function uploadMultiple(files) {
const formData = new FormData();
files.forEach((file, index) => {
formData.append(`files`, file);
});
return fetch('/api/upload-multiple', {
method: 'POST',
body: formData
});
}
```
## WebSockets
```javascript
class WebSocketClient {
constructor(url) {
this.url = url;
this.ws = null;
this.listeners = new Map();
this.reconnectAttempts = 0;
this.maxReconnectAttempts = 5;
this.reconnectDelay = 1000;
}
connect() {
return new Promise((resolve, reject) => {
this.ws = new WebSocket(this.url);
this.ws.onopen = () => {
console.log('WebSocket connected');
this.reconnectAttempts = 0;
resolve();
};
this.ws.onclose = (event) => {
console.log('WebSocket closed:', event.code, event.reason);
this.handleReconnect();
};
this.ws.onerror = (error) => {
console.error('WebSocket error:', error);
reject(error);
};
this.ws.onmessage = (event) => {
try {
const data = JSON.parse(event.data);
this.handleMessage(data);
} catch (error) {
console.error('Failed to parse message:', error);
}
};
});
}
handleMessage(data) {
const { type, payload } = data;
const callbacks = this.listeners.get(type) || [];
callbacks.forEach((callback) => callback(payload));
}
on(type, callback) {
if (!this.listeners.has(type)) {
this.listeners.set(type, []);
}
this.listeners.get(type).push(callback);
// Retourner une fonction pour se désabonner
return () => {
const callbacks = this.listeners.get(type);
const index = callbacks.indexOf(callback);
if (index > -1) {
callbacks.splice(index, 1);
}
};
}
send(type, payload) {
if (this.ws?.readyState === WebSocket.OPEN) {
this.ws.send(JSON.stringify({ type, payload }));
} else {
console.warn('WebSocket not connected');
}
}
handleReconnect() {
if (this.reconnectAttempts < this.maxReconnectAttempts) {
this.reconnectAttempts++;
const delay = this.reconnectDelay * Math.pow(2, this.reconnectAttempts - 1);
console.log(`Reconnecting in ${delay}ms (attempt ${this.reconnectAttempts})`);
setTimeout(() => {
this.connect().catch(console.error);
}, delay);
} else {
console.error('Max reconnection attempts reached');
}
}
disconnect() {
if (this.ws) {
this.ws.close();
this.ws = null;
}
}
}
// Usage
const ws = new WebSocketClient('wss://api.example.com/ws');
await ws.connect();
const unsubscribe = ws.on('message', (data) => {
console.log('New message:', data);
});
ws.send('subscribe', { channel: 'updates' });
// Cleanup
unsubscribe();
ws.disconnect();
```
## Server-Sent Events (SSE)
```javascript
class SSEClient {
constructor(url) {
this.url = url;
this.eventSource = null;
this.listeners = new Map();
}
connect() {
this.eventSource = new EventSource(this.url);
this.eventSource.onopen = () => {
console.log('SSE connected');
};
this.eventSource.onerror = (error) => {
console.error('SSE error:', error);
// EventSource reconnecte automatiquement
};
// Message par défaut
this.eventSource.onmessage = (event) => {
this.emit('message', JSON.parse(event.data));
};
}
on(eventType, callback) {
if (!this.listeners.has(eventType)) {
this.listeners.set(eventType, []);
// Écouter ce type d'événement sur l'EventSource
this.eventSource?.addEventListener(eventType, (event) => {
this.emit(eventType, JSON.parse(event.data));
});
}
this.listeners.get(eventType).push(callback);
return () => {
const callbacks = this.listeners.get(eventType);
const index = callbacks.indexOf(callback);
if (index > -1) callbacks.splice(index, 1);
};
}
emit(eventType, data) {
const callbacks = this.listeners.get(eventType) || [];
callbacks.forEach((cb) => cb(data));
}
disconnect() {
this.eventSource?.close();
this.eventSource = null;
}
}
// Usage
const sse = new SSEClient('/api/events');
sse.connect();
sse.on('notification', (data) => {
showNotification(data);
});
sse.on('update', (data) => {
updateUI(data);
});
```
## Retry et Résilience
```javascript
async function fetchWithRetry(url, options = {}, maxRetries = 3) {
let lastError;
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
const response = await fetch(url, options);
if (response.ok) {
return response;
}
// Ne pas retry pour les erreurs client (4xx)
if (response.status >= 400 && response.status < 500) {
throw new APIError('Client error', response.status);
}
throw new Error(`HTTP ${response.status}`);
} catch (error) {
lastError = error;
if (attempt < maxRetries) {
// Exponential backoff
const delay = Math.min(1000 * Math.pow(2, attempt - 1), 10000);
console.log(`Retry ${attempt}/${maxRetries} after ${delay}ms`);
await new Promise((resolve) => setTimeout(resolve, delay));
}
}
}
throw lastError;
}
// Circuit breaker pattern
class CircuitBreaker {
constructor(threshold = 5, timeout = 30000) {
this.threshold = threshold;
this.timeout = timeout;
this.failures = 0;
this.state = 'CLOSED';
this.nextAttempt = Date.now();
}
async execute(fn) {
if (this.state === 'OPEN') {
if (Date.now() < this.nextAttempt) {
throw new Error('Circuit breaker is OPEN');
}
this.state = 'HALF-OPEN';
}
try {
const result = await fn();
this.onSuccess();
return result;
} catch (error) {
this.onFailure();
throw error;
}
}
onSuccess() {
this.failures = 0;
this.state = 'CLOSED';
}
onFailure() {
this.failures++;
if (this.failures >= this.threshold) {
this.state = 'OPEN';
this.nextAttempt = Date.now() + this.timeout;
}
}
}

# Agent DOM Manipulation
## Responsabilité
Maîtriser les APIs DOM natives pour manipuler efficacement le document HTML.
## Tu NE fais PAS
- ❌ Utiliser les APIs framework (Virtual DOM React, Vue reactivity) → `frameworks/`
- ❌ Appeler des APIs HTTP (fetch, WebSocket) → `api-integration.md`
- ❌ Créer des animations CSS ou avec bibliothèques → `styling/animations.md`
- ❌ Gérer le state global → `state-management/`
## Sélection d'Éléments
### Méthodes de sélection
```javascript
// Par ID (le plus rapide)
const element = document.getElementById('my-id');
// Par sélecteur CSS (un seul élément)
const button = document.querySelector('.btn-primary');
const form = document.querySelector('form[data-validate]');
// Tous les éléments correspondants
const items = document.querySelectorAll('.list-item');
const buttons = document.querySelectorAll('button[type="submit"]');
// Conversion en array pour méthodes array
const itemsArray = [...document.querySelectorAll('.item')];
const filtered = itemsArray.filter((item) => item.dataset.active === 'true');
// Sélection dans un contexte
const container = document.querySelector('.container');
const innerButton = container.querySelector('.btn');
const innerItems = container.querySelectorAll('.item');
// Collections live (se mettent à jour automatiquement)
const forms = document.forms;
const images = document.images;
const links = document.links;
```
### Traversée du DOM
```javascript
const element = document.querySelector('.current');
// Parents
element.parentElement;
element.parentNode;
element.closest('.ancestor'); // Ancêtre le plus proche
// Enfants
element.children; // HTMLCollection (éléments seulement)
element.childNodes; // NodeList (inclut texte, commentaires)
element.firstElementChild;
element.lastElementChild;
// Frères/Sœurs
element.previousElementSibling;
element.nextElementSibling;
// Vérifications
element.matches('.selector'); // Correspond au sélecteur?
element.contains(otherElement); // Contient l'élément?
```
## Création et Modification
### Créer des éléments
```javascript
// Création simple
const div = document.createElement('div');
div.className = 'card';
div.id = 'card-1';
div.textContent = 'Hello World';
// Attributs
div.setAttribute('data-id', '123');
div.dataset.category = 'featured'; // data-category
// Classes
div.classList.add('active', 'highlighted');
div.classList.remove('hidden');
div.classList.toggle('expanded');
div.classList.replace('old-class', 'new-class');
const hasClass = div.classList.contains('active');
// Styles inline (éviter si possible)
div.style.backgroundColor = 'blue';
div.style.cssText = 'color: white; padding: 10px;';
// HTML (attention XSS!)
div.innerHTML = '<span>Contenu</span>';
// Template plus sûr
const template = document.getElementById('card-template');
const clone = template.content.cloneNode(true);
```
### Insertion d'éléments
```javascript
const parent = document.querySelector('.container');
const newElement = document.createElement('div');
const reference = document.querySelector('.reference');
// Méthodes modernes (préférées)
parent.append(newElement); // À la fin (multiple éléments OK)
parent.prepend(newElement); // Au début
reference.before(newElement); // Avant l'élément
reference.after(newElement); // Après l'élément
reference.replaceWith(newElement); // Remplacer
// Méthodes classiques
parent.appendChild(newElement);
parent.insertBefore(newElement, reference);
parent.replaceChild(newElement, oldElement);
// insertAdjacentHTML (performant pour HTML string)
parent.insertAdjacentHTML('beforebegin', '<div>Before</div>');
parent.insertAdjacentHTML('afterbegin', '<div>First child</div>');
parent.insertAdjacentHTML('beforeend', '<div>Last child</div>');
parent.insertAdjacentHTML('afterend', '<div>After</div>');
```
### Suppression
```javascript
// Moderne
element.remove();
// Classique
parent.removeChild(element);
// Vider un conteneur
container.innerHTML = ''; // Simple mais recrée tout
container.replaceChildren(); // Plus propre
// Supprimer en préservant les event listeners
while (container.firstChild) {
container.removeChild(container.firstChild);
}
```
## Gestion des Événements
### addEventListener
```javascript
const button = document.querySelector('button');
// Syntaxe de base
button.addEventListener('click', (event) => {
console.log('Clicked!', event.target);
});
// Avec options
button.addEventListener('click', handleClick, {
once: true, // Se déclenche une seule fois
passive: true, // N'appellera pas preventDefault (perf scroll)
capture: true // Phase de capture au lieu de bubbling
});
// Supprimer un listener
function handleClick(event) {
console.log('Clicked');
}
button.addEventListener('click', handleClick);
button.removeEventListener('click', handleClick); // Même référence requise
```
### Event Delegation
```javascript
// Au lieu d'attacher à chaque élément
// ❌ Mauvais
document.querySelectorAll('.item').forEach((item) => {
item.addEventListener('click', handleItemClick);
});
// ✅ Bon - Event delegation
document.querySelector('.list').addEventListener('click', (event) => {
const item = event.target.closest('.item');
if (item) {
handleItemClick(item);
}
});
// Pattern complet
class ListManager {
constructor(container) {
this.container = container;
this.container.addEventListener('click', this.handleClick.bind(this));
}
handleClick(event) {
const target = event.target;
if (target.matches('.delete-btn')) {
this.handleDelete(target.closest('.item'));
} else if (target.matches('.edit-btn')) {
this.handleEdit(target.closest('.item'));
} else if (target.matches('.item')) {
this.handleSelect(target);
}
}
handleDelete(item) { /* ... */ }
handleEdit(item) { /* ... */ }
handleSelect(item) { /* ... */ }
}
```
### Types d'événements courants
```javascript
// Mouse events
element.addEventListener('click', handler);
element.addEventListener('dblclick', handler);
element.addEventListener('mouseenter', handler); // Ne bubble pas
element.addEventListener('mouseleave', handler);
element.addEventListener('mouseover', handler); // Bubble
element.addEventListener('mouseout', handler);
// Keyboard events
document.addEventListener('keydown', (e) => {
if (e.key === 'Escape') closeModal();
if (e.key === 'Enter' && e.ctrlKey) submit();
});
// Form events
form.addEventListener('submit', (e) => {
e.preventDefault();
// Traitement
});
input.addEventListener('input', (e) => {
// À chaque frappe
});
input.addEventListener('change', (e) => {
// Quand la valeur change et perd le focus
});
// Focus events
input.addEventListener('focus', handler);
input.addEventListener('blur', handler);
input.addEventListener('focusin', handler); // Bubble
// Scroll et resize
window.addEventListener('scroll', handler, { passive: true });
window.addEventListener('resize', handler);
// Custom events
const customEvent = new CustomEvent('userLoggedIn', {
detail: { userId: '123', name: 'John' },
bubbles: true
});
element.dispatchEvent(customEvent);
```
### Contrôle de propagation
```javascript
element.addEventListener('click', (event) => {
// Empêcher l'action par défaut
event.preventDefault();
// Empêcher la propagation aux parents
event.stopPropagation();
// Empêcher aussi les autres listeners sur cet élément
event.stopImmediatePropagation();
});
// Vérifier si on peut preventDefault
if (event.cancelable) {
event.preventDefault();
}
```
## Formulaires
```javascript
const form = document.querySelector('form');
// Accès aux éléments
const input = form.elements.username; // par name
const inputs = form.elements; // FormData-like collection
// FormData API
form.addEventListener('submit', (event) => {
event.preventDefault();
const formData = new FormData(form);
// Accès aux valeurs
const username = formData.get('username');
const tags = formData.getAll('tags'); // Pour checkboxes multiples
// Conversion en objet
const data = Object.fromEntries(formData);
// Envoi
fetch('/api/submit', {
method: 'POST',
body: formData // ou JSON.stringify(data)
});
});
// Validation native
const input = document.querySelector('input');
input.setCustomValidity('Message d\'erreur personnalisé');
input.reportValidity(); // Affiche l'erreur
form.checkValidity(); // Vérifie tous les champs
// Reset
form.reset();
```
## Optimisation Performance
### Minimiser les reflows
```javascript
// ❌ Mauvais - Multiple reflows
items.forEach((item) => {
container.appendChild(item);
});
// ✅ Bon - Un seul reflow avec DocumentFragment
const fragment = document.createDocumentFragment();
items.forEach((item) => {
fragment.appendChild(item);
});
container.appendChild(fragment);
// ✅ Ou avec append (moderne)
container.append(...items);
```
### Batch les modifications de style
```javascript
// ❌ Mauvais - Lectures/écritures alternées
elements.forEach((el) => {
const height = el.offsetHeight; // Lecture (force reflow)
el.style.height = height + 10 + 'px'; // Écriture
});
// ✅ Bon - Séparer lectures et écritures
const heights = elements.map((el) => el.offsetHeight); // Toutes les lectures
elements.forEach((el, i) => {
el.style.height = heights[i] + 10 + 'px'; // Toutes les écritures
});
```
### Debounce et Throttle
```javascript
// Debounce - Attendre que l'utilisateur arrête
function debounce(fn, delay) {
let timeoutId;
return (...args) => {
clearTimeout(timeoutId);
timeoutId = setTimeout(() => fn(...args), delay);
};
}
const handleSearch = debounce((query) => {
fetchResults(query);
}, 300);
input.addEventListener('input', (e) => handleSearch(e.target.value));
// Throttle - Limiter la fréquence
function throttle(fn, limit) {
let inThrottle;
return (...args) => {
if (!inThrottle) {
fn(...args);
inThrottle = true;
setTimeout(() => (inThrottle = false), limit);
}
};
}
window.addEventListener('scroll', throttle(updatePosition, 100), { passive: true });
```
### Intersection Observer
```javascript
// Lazy loading, infinite scroll, animations au scroll
const observer = new IntersectionObserver(
(entries) => {
entries.forEach((entry) => {
if (entry.isIntersecting) {
entry.target.classList.add('visible');
// Optionnel : arrêter d'observer
observer.unobserve(entry.target);
}
});
},
{
threshold: 0.1, // 10% visible
rootMargin: '50px' // Marge autour du viewport
}
);
document.querySelectorAll('.animate-on-scroll').forEach((el) => {
observer.observe(el);
});
```

# Agent JavaScript Moderne
## Responsabilité
Maîtriser et implémenter les fonctionnalités JavaScript modernes (ES6+) pour écrire du code propre, performant et maintenable.
## Tu NE fais PAS
- ❌ Gérer le typage (TypeScript, interfaces, generics) → `typescript.md`
- ❌ Manipuler le DOM directement (querySelector, events) → `dom-manipulation.md`
- ❌ Appeler des APIs (fetch, REST, WebSockets) → `api-integration.md`
- ❌ Implémenter des hooks React spécifiques → skill `react-expert`
## ES6+ Essentials
### Déclarations de variables
```javascript
// const par défaut
const API_URL = 'https://api.example.com';
const config = { debug: true };
// let seulement si réassignation nécessaire
let count = 0;
count += 1;
// Éviter var (hoisting, scope function)
```
### Arrow Functions
```javascript
// Syntaxe courte
const double = (x) => x * 2;
const add = (a, b) => a + b;
// Avec corps de fonction
const processData = (data) => {
const result = transform(data);
return result;
};
// Attention au this (arrow capture le this lexical)
class Counter {
count = 0;
// Arrow préserve le this
increment = () => {
this.count++;
};
// Méthode traditionnelle - this dépend du contexte d'appel
decrement() {
this.count--;
}
}
```
### Destructuring
```javascript
// Objets
const user = { name: 'John', age: 30, city: 'Paris' };
const { name, age } = user;
const { name: userName, ...rest } = user;
// Avec valeurs par défaut
const { role = 'user' } = user;
// Renommage
const { name: fullName } = user;
// Tableaux
const [first, second, ...others] = [1, 2, 3, 4, 5];
const [, , third] = [1, 2, 3]; // Skip elements
// Paramètres de fonction
function createUser({ name, email, role = 'user' }) {
return { name, email, role };
}
```
### Spread Operator
```javascript
// Fusion d'objets
const defaults = { theme: 'light', lang: 'fr' };
const userPrefs = { theme: 'dark' };
const settings = { ...defaults, ...userPrefs };
// Copie de tableaux
const original = [1, 2, 3];
const copy = [...original];
const extended = [...original, 4, 5];
// Arguments de fonction
const numbers = [1, 2, 3];
Math.max(...numbers);
```
### Template Literals
```javascript
const name = 'World';
const greeting = `Hello, ${name}!`;
// Multiline
const html = `
<div class="card">
<h2>${title}</h2>
<p>${description}</p>
</div>
`;
// Tagged templates
function highlight(strings, ...values) {
return strings.reduce((acc, str, i) => {
return acc + str + (values[i] ? `<mark>${values[i]}</mark>` : '');
}, '');
}
const result = highlight`Search for ${query} in ${category}`;
```
## Async JavaScript
### Promises
```javascript
// Création
const fetchData = () => {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve({ data: 'success' });
}, 1000);
});
};
// Chaînage
fetchData()
.then((result) => transform(result))
.then((transformed) => save(transformed))
.catch((error) => console.error(error))
.finally(() => cleanup());
// Promise.all - parallèle
const [users, posts] = await Promise.all([
fetchUsers(),
fetchPosts()
]);
// Promise.allSettled - toutes, même si erreurs
const results = await Promise.allSettled([
fetchUsers(),
fetchPosts()
]);
// results: [{ status: 'fulfilled', value: ... }, { status: 'rejected', reason: ... }]
// Promise.race - première résolue
const fastest = await Promise.race([fetch1(), fetch2()]);
// Promise.any - première réussie (ignore les rejets)
const firstSuccess = await Promise.any([fetch1(), fetch2()]);
```
### Async/Await
```javascript
// Fonction async
async function fetchUserData(userId) {
try {
const response = await fetch(`/api/users/${userId}`);
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
const user = await response.json();
return user;
} catch (error) {
console.error('Failed to fetch user:', error);
throw error;
}
}
// Arrow function async
const fetchPosts = async () => {
const response = await fetch('/api/posts');
return response.json();
};
// Parallel async
async function loadDashboard() {
const [users, posts, stats] = await Promise.all([
fetchUsers(),
fetchPosts(),
fetchStats()
]);
return { users, posts, stats };
}
// Sequential async (quand ordre importe)
async function processSequentially(items) {
const results = [];
for (const item of items) {
const result = await processItem(item);
results.push(result);
}
return results;
}
```
## Modules ES
### Export
```javascript
// Named exports
export const API_URL = 'https://api.example.com';
export function fetchUsers() {
return fetch(`${API_URL}/users`);
}
export class UserService {
// ...
}
// Export groupé
const helper1 = () => {};
const helper2 = () => {};
export { helper1, helper2 };
// Renommage à l'export
export { helper1 as utilHelper };
// Default export (un seul par module)
export default class App {
// ...
}
```
### Import
```javascript
// Named imports
import { fetchUsers, API_URL } from './api.js';
// Renommage
import { fetchUsers as getUsers } from './api.js';
// Default import
import App from './App.js';
// Tout importer
import * as api from './api.js';
api.fetchUsers();
// Import dynamique (code splitting)
const module = await import('./heavy-module.js');
module.doSomething();
// Import conditionnel
if (condition) {
const { feature } = await import('./feature.js');
feature();
}
```
## Patterns Modernes
### Optional Chaining & Nullish Coalescing
```javascript
// Optional chaining (?.)
const city = user?.address?.city;
const firstItem = array?.[0];
const result = obj?.method?.();
// Nullish coalescing (??)
const value = input ?? 'default'; // null ou undefined seulement
const count = data.count ?? 0;
// Différence avec ||
const zero = 0 || 'default'; // 'default' (0 est falsy)
const zero2 = 0 ?? 'default'; // 0 (0 n'est pas null/undefined)
```
### Méthodes de tableau modernes
```javascript
const users = [
{ name: 'Alice', age: 25, active: true },
{ name: 'Bob', age: 30, active: false },
{ name: 'Charlie', age: 35, active: true }
];
// map - transformer
const names = users.map((user) => user.name);
// filter - filtrer
const activeUsers = users.filter((user) => user.active);
// find - trouver un élément
const bob = users.find((user) => user.name === 'Bob');
// findIndex - trouver l'index
const bobIndex = users.findIndex((user) => user.name === 'Bob');
// some - au moins un
const hasActive = users.some((user) => user.active);
// every - tous
const allActive = users.every((user) => user.active);
// reduce - réduire à une valeur
const totalAge = users.reduce((sum, user) => sum + user.age, 0);
// flatMap - map + flatten
const tags = posts.flatMap((post) => post.tags);
// at - accès par index (négatif supporté)
const last = users.at(-1);
// Chaînage
const result = users
.filter((user) => user.active)
.map((user) => user.name)
.sort();
```
### Classes modernes
```javascript
class EventEmitter {
// Champs privés
#listeners = new Map();
// Champs publics avec initialisation
maxListeners = 10;
// Champs statiques
static defaultMaxListeners = 10;
constructor(options = {}) {
this.maxListeners = options.maxListeners ?? EventEmitter.defaultMaxListeners;
}
// Méthode publique
on(event, callback) {
if (!this.#listeners.has(event)) {
this.#listeners.set(event, []);
}
this.#listeners.get(event).push(callback);
return this;
}
// Méthode privée
#validateEvent(event) {
if (typeof event !== 'string') {
throw new TypeError('Event must be a string');
}
}
// Getter
get listenerCount() {
let count = 0;
for (const listeners of this.#listeners.values()) {
count += listeners.length;
}
return count;
}
// Méthode statique
static create(options) {
return new EventEmitter(options);
}
}
```
## Bonnes Pratiques
### Immutabilité
```javascript
// Éviter les mutations
// Mauvais
const updateUser = (user, name) => {
user.name = name;
return user;
};
// Bon
const updateUser = (user, name) => ({
...user,
name
});
// Pour les tableaux
const addItem = (array, item) => [...array, item];
const removeItem = (array, index) => [
...array.slice(0, index),
...array.slice(index + 1)
];
```
### Pure Functions
```javascript
// Fonction pure : même entrée = même sortie, pas d'effets de bord
const calculateTotal = (items) => {
return items.reduce((sum, item) => sum + item.price * item.quantity, 0);
};
// Impure : dépend de l'état externe
let taxRate = 0.2;
const calculateWithTax = (amount) => amount * (1 + taxRate); // Impure
```

# Orchestrateur JavaScript
## Responsabilité
Coordonner les agents spécialisés dans JavaScript moderne, TypeScript, manipulation du DOM et intégration d'APIs.
## Tu NE fais PAS
- ❌ Implémenter directement (déléguer aux agents spécialisés) → agents sous coordination
- ❌ Gérer les frameworks (React hooks, Vue Composition API) → `frameworks/orchestrator.md`
- ❌ Gérer le state management global → `state-management/orchestrator.md`
- ❌ Tester le code JavaScript → `testing/orchestrator.md`
## Agents sous ma coordination
| Agent | Fichier | Spécialisation |
|-------|---------|----------------|
| JavaScript Moderne | `javascript-moderne.md` | ES6+, async/await, modules |
| TypeScript | `typescript.md` | Typage, interfaces, generics |
| DOM Manipulation | `dom-manipulation.md` | DOM API, événements |
| API Integration | `api-integration.md` | Fetch, REST, GraphQL |
## Règles de Routage
```
SI question porte sur [ES6, ES2015+, async, await, Promise, modules, destructuring]
→ javascript-moderne.md
SI question porte sur [TypeScript, types, interface, generic, utility types]
→ typescript.md
SI question porte sur [DOM, querySelector, événements, event delegation]
→ dom-manipulation.md
SI question porte sur [fetch, API, REST, GraphQL, WebSocket, HTTP]

---
## Types de Base
### Types primitifs
```typescript
// Primitifs
const name: string = 'John';
const age: number = 30;
const isActive: boolean = true;
const data: null = null;
const value: undefined = undefined;
// Arrays
const numbers: number[] = [1, 2, 3];
const strings: Array<string> = ['a', 'b', 'c'];
// Tuples
const pair: [string, number] = ['age', 30];
const triple: [string, number, boolean] = ['John', 30, true];
// Enum
enum Status {
Pending = 'PENDING',
Active = 'ACTIVE',
Completed = 'COMPLETED'
}
// Const enum (inline à la compilation)
const enum Direction {
Up,
Down,
Left,
Right
}
// Union types
type StringOrNumber = string | number;
type Status = 'pending' | 'active' | 'completed';
// Literal types
type Theme = 'light' | 'dark';
type Size = 'sm' | 'md' | 'lg' | 'xl';
```
### Objects et Interfaces
```typescript
// Interface (extensible, pour objets)
interface User {
id: string;
name: string;
email: string;
age?: number; // optionnel
readonly createdAt: Date; // lecture seule
}
// Extension d'interface
interface Admin extends User {
permissions: string[];
role: 'admin';
}
// Type alias (pour unions, intersections, mapped types)
type UserOrAdmin = User | Admin;
type UserWithRole = User & { role: string };
// Index signatures
interface Dictionary {
[key: string]: string;
}
interface NumberMap {
[key: string]: number;
}
// Record type (préféré pour dictionnaires)
type UserRoles = Record<string, 'admin' | 'user' | 'guest'>;
```
## Generics
### Fonctions génériques
```typescript
// Generic simple
function identity<T>(value: T): T {
return value;
}
const str = identity('hello'); // type: string
const num = identity(42); // type: number
// Multiple generics
function pair<T, U>(first: T, second: U): [T, U] {
return [first, second];
}
// Generic avec contrainte
function getProperty<T, K extends keyof T>(obj: T, key: K): T[K] {
return obj[key];
}
const user = { name: 'John', age: 30 };
const name = getProperty(user, 'name'); // type: string
const age = getProperty(user, 'age'); // type: number
// Generic avec valeur par défaut
function createArray<T = string>(length: number, value: T): T[] {
return Array(length).fill(value);
}
```
### Interfaces et Classes génériques
```typescript
// Interface générique
interface Response<T> {
data: T;
status: number;
message: string;
}
interface PaginatedResponse<T> extends Response<T[]> {
page: number;
totalPages: number;
totalItems: number;
}
// Usage
type UserResponse = Response<User>;
type UsersResponse = PaginatedResponse<User>;
// Classe générique
class Repository<T extends { id: string }> {
private items: Map<string, T> = new Map();
add(item: T): void {
this.items.set(item.id, item);
}
get(id: string): T | undefined {
return this.items.get(id);
}
getAll(): T[] {
return Array.from(this.items.values());
}
}
const userRepo = new Repository<User>();
```
## Utility Types
### Types de transformation
```typescript
interface User {
id: string;
name: string;
email: string;
age: number;
}
// Partial - tous les champs optionnels
type PartialUser = Partial<User>;
// { id?: string; name?: string; email?: string; age?: number; }
// Required - tous les champs requis
type RequiredUser = Required<PartialUser>;
// Readonly - tous les champs en lecture seule
type ReadonlyUser = Readonly<User>;
// Pick - sélectionner certains champs
type UserPreview = Pick<User, 'id' | 'name'>;
// { id: string; name: string; }
// Omit - exclure certains champs
type UserWithoutId = Omit<User, 'id'>;
// { name: string; email: string; age: number; }
// Record - créer un type objet
type UsersByRole = Record<'admin' | 'user', User[]>;
// Exclude - exclure d'une union
type NotAdmin = Exclude<'admin' | 'user' | 'guest', 'admin'>;
// 'user' | 'guest'
// Extract - extraire d'une union
type OnlyAdmin = Extract<'admin' | 'user' | 'guest', 'admin' | 'superadmin'>;
// 'admin'
// NonNullable - exclure null et undefined
type ValidString = NonNullable<string | null | undefined>;
// string
// ReturnType - type de retour d'une fonction
type FetchResult = ReturnType<typeof fetchUser>;
// Parameters - types des paramètres
type FetchParams = Parameters<typeof fetchUser>;
// Awaited - type résolu d'une Promise
type ResolvedUser = Awaited<Promise<User>>;
// User
```
### Mapped Types
```typescript
// Mapped type custom
type Nullable<T> = {
[K in keyof T]: T[K] | null;
};
type NullableUser = Nullable<User>;
// Avec modification de clés
type Getters<T> = {
[K in keyof T as `get${Capitalize<string & K>}`]: () => T[K];
};
type UserGetters = Getters<User>;
// { getId: () => string; getName: () => string; ... }
// Conditional mapped type
type OptionalIfUndefined<T> = {
[K in keyof T as undefined extends T[K] ? K : never]?: T[K];
} & {
[K in keyof T as undefined extends T[K] ? never : K]: T[K];
};
```
## Conditional Types
```typescript
// Type conditionnel simple
type IsString<T> = T extends string ? true : false;
type A = IsString<string>; // true
type B = IsString<number>; // false
// Inférence avec infer
type UnwrapPromise<T> = T extends Promise<infer U> ? U : T;
type Unwrapped = UnwrapPromise<Promise<User>>; // User
// Array element type
type ArrayElement<T> = T extends (infer E)[] ? E : never;
type Element = ArrayElement<string[]>; // string
// Function return type custom
type AsyncReturnType<T extends (...args: any) => Promise<any>> =
T extends (...args: any) => Promise<infer R> ? R : never;
```
## Type Guards
```typescript
// typeof guard
function process(value: string | number) {
if (typeof value === 'string') {
return value.toUpperCase(); // value est string
}
return value.toFixed(2); // value est number
}
// instanceof guard
function handleError(error: Error | string) {
if (error instanceof Error) {
return error.message;
}
return error;
}
// in guard
interface Dog {
bark(): void;
}
interface Cat {
meow(): void;
}
function speak(animal: Dog | Cat) {
if ('bark' in animal) {
animal.bark();
} else {
animal.meow();
}
}
// Custom type guard
function isUser(value: unknown): value is User {
return (
typeof value === 'object' &&
value !== null &&
'id' in value &&
'name' in value &&
'email' in value
);
}
// Usage
function processData(data: unknown) {
if (isUser(data)) {
console.log(data.name); // TypeScript sait que c'est un User
}
}
// Assertion function
function assertIsUser(value: unknown): asserts value is User {
if (!isUser(value)) {
throw new Error('Not a valid user');
}
}
```
## Patterns Avancés
### Discriminated Unions
```typescript
// Tag commun pour discriminer
interface LoadingState {
status: 'loading';
}
interface SuccessState<T> {
status: 'success';
data: T;
}
interface ErrorState {
status: 'error';
error: Error;
}
type AsyncState<T> = LoadingState | SuccessState<T> | ErrorState;
function renderState<T>(state: AsyncState<T>) {
switch (state.status) {
case 'loading':
return 'Loading...';
case 'success':
return `Data: ${JSON.stringify(state.data)}`;
case 'error':
return `Error: ${state.error.message}`;
}
}
```
### Template Literal Types
```typescript
type EventName = 'click' | 'focus' | 'blur';
type Handler = `on${Capitalize<EventName>}`;
// 'onClick' | 'onFocus' | 'onBlur'
type HTTPMethod = 'GET' | 'POST' | 'PUT' | 'DELETE';
type Endpoint = '/users' | '/posts';
type Route = `${HTTPMethod} ${Endpoint}`;
// 'GET /users' | 'GET /posts' | 'POST /users' | ...
// Extraction avec infer
type ExtractParams<T extends string> =
T extends `${infer _Start}:${infer Param}/${infer Rest}`
? Param | ExtractParams<`/${Rest}`>
: T extends `${infer _Start}:${infer Param}`
? Param
: never;
type Params = ExtractParams<'/users/:userId/posts/:postId'>;
// 'userId' | 'postId'
```
## Configuration tsconfig.json

# Agent Bundle Optimization
## Responsabilité
Optimiser la taille et le chargement des bundles JavaScript.
## Tu NE fais PAS
- ❌ Mesurer et optimiser les Core Web Vitals (LCP, FID, CLS) → `core-web-vitals.md`
- ❌ Configurer le bundler en détail (plugins, loaders) → `tooling/build-tools.md`
- ❌ Optimiser les images (formats, responsive) → Performance images
- ❌ Optimiser le backend (API response time) → skill `backend-developer`
## Analyse de Bundle
### Vite
```bash
# Visualiser le bundle
npx vite-bundle-visualizer
# Ou avec rollup-plugin-visualizer
```
```typescript
// vite.config.ts
import { visualizer } from 'rollup-plugin-visualizer';
export default defineConfig({
plugins: [
visualizer({
open: true,
filename: 'stats.html',
gzipSize: true,
}),
],
});
```
### Webpack
```bash
# Bundle analyzer
npx webpack-bundle-analyzer stats.json
# Générer les stats
webpack --profile --json > stats.json
```
```javascript
// webpack.config.js
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
module.exports = {
plugins: [
new BundleAnalyzerPlugin({
analyzerMode: 'static',
openAnalyzer: false,
}),
],
};
```
## Code Splitting
### Dynamic Imports
```javascript
// Import dynamique de base
const module = await import('./heavy-module.js');
module.doSomething();
// React lazy
const HeavyComponent = lazy(() => import('./HeavyComponent'));
// Avec webpack magic comments
const AdminPanel = lazy(() =>
import(
/* webpackChunkName: "admin" */
/* webpackPrefetch: true */
'./AdminPanel'
)
);
// Grouper plusieurs modules
const [moduleA, moduleB] = await Promise.all([
import('./moduleA'),
import('./moduleB'),
]);
```
### Route-based Splitting
```tsx
// React Router
import { lazy, Suspense } from 'react';
import { Routes, Route } from 'react-router-dom';
const Home = lazy(() => import('./pages/Home'));
const Dashboard = lazy(() => import('./pages/Dashboard'));
const Settings = lazy(() => import('./pages/Settings'));
function App() {
return (
<Suspense fallback={<LoadingSpinner />}>
<Routes>
<Route path="/" element={<Home />} />
<Route path="/dashboard" element={<Dashboard />} />
<Route path="/settings" element={<Settings />} />
</Routes>
</Suspense>
);
}
```
### Component-based Splitting
```tsx
// Charger à la demande
function ProductPage() {
const [showReviews, setShowReviews] = useState(false);
return (
<div>
<ProductInfo />
<button onClick={() => setShowReviews(true)}>
Show Reviews
</button>
{showReviews && (
<Suspense fallback={<Skeleton />}>
<Reviews />
</Suspense>
)}
</div>
);
}
const Reviews = lazy(() => import('./Reviews'));
```
## Tree Shaking
### Configuration
```typescript
// vite.config.ts
export default defineConfig({
build: {
rollupOptions: {
treeshake: {
moduleSideEffects: false,
propertyReadSideEffects: false,
},
},
},
});
```
### Bonnes Pratiques
```javascript
// ✅ Bon - Import nommé (tree-shakable)
import { debounce } from 'lodash-es';
// ❌ Mauvais - Import complet
import _ from 'lodash';
// ✅ Bon - Export nommé
export const helper1 = () => {};
export const helper2 = () => {};
// ❌ À éviter - Default export d'objet
export default {
helper1: () => {},
helper2: () => {},
};
```
### Marquer les side effects
```json
// package.json
{
"name": "my-lib",
"sideEffects": false
}
// Ou avec fichiers spécifiques
{
"sideEffects": [
"*.css",
"*.scss",
"./src/polyfills.js"
]
}
```
## Lazy Loading
### Composants
```tsx
// Avec préchargement
const HeavyComponent = lazy(() => import('./HeavyComponent'));
// Précharger au hover
function Button() {
const handleMouseEnter = () => {
import('./HeavyComponent');
};
return (
<button onMouseEnter={handleMouseEnter}>
Load Component
</button>
);
}
```
### Images
```html
<!-- Lazy loading natif -->
<img src="photo.jpg" loading="lazy" alt="Photo" />
<!-- Avec Intersection Observer -->
<img data-src="photo.jpg" class="lazy" alt="Photo" />
```
```javascript
const lazyImages = document.querySelectorAll('.lazy');
const observer = new IntersectionObserver((entries) => {
entries.forEach((entry) => {
if (entry.isIntersecting) {
const img = entry.target;
img.src = img.dataset.src;
img.classList.remove('lazy');
observer.unobserve(img);
}
});
});
lazyImages.forEach((img) => observer.observe(img));
```
## Optimisation des Dépendances
### Remplacer les dépendances lourdes
```javascript
// ❌ Moment.js (~300kb)
import moment from 'moment';
// ✅ Day.js (~2kb)
import dayjs from 'dayjs';
// ❌ Lodash complet (~70kb)
import _ from 'lodash';
// ✅ Lodash-es avec imports nommés
import { debounce, throttle } from 'lodash-es';
// ❌ Date-fns complet
import * as dateFns from 'date-fns';
// ✅ Date-fns avec imports spécifiques
import { format, parseISO } from 'date-fns';
```
### Externaliser les dépendances
```typescript
// vite.config.ts
export default defineConfig({
build: {
rollupOptions: {
external: ['react', 'react-dom'],
output: {
globals: {
react: 'React',
'react-dom': 'ReactDOM',
},
},
},
},
});
```
### Splitting des vendors
```typescript
// vite.config.ts
export default defineConfig({
build: {
rollupOptions: {
output: {
manualChunks: {
vendor: ['react', 'react-dom'],
router: ['react-router-dom'],
ui: ['@radix-ui/react-dialog', '@radix-ui/react-dropdown-menu'],
},
},
},
},
});
// Ou avec fonction
manualChunks(id) {
if (id.includes('node_modules')) {
if (id.includes('react')) {
return 'vendor';
}
if (id.includes('@radix-ui')) {
return 'ui';
}
}
}
```
## Compression
```typescript
// vite.config.ts
import viteCompression from 'vite-plugin-compression';
export default defineConfig({
plugins: [
viteCompression({
algorithm: 'gzip',
threshold: 1024,
}),
viteCompression({
algorithm: 'brotliCompress',
ext: '.br',
}),
],
});
```
## Métriques Cibles
| Métrique | Objectif |
|----------|----------|
| Bundle initial | < 200kb (gzipped) |
| Chunk par route | < 100kb (gzipped) |
| Time to Interactive | < 3.8s |
| Total Blocking Time | < 200ms |

Temps pour afficher le plus grand élément visible.
**Objectifs :**
- Bon : < 2.5s
- À améliorer : 2.5s - 4s
- Mauvais : > 4s
**Optimisations :**
```html
<!-- Preload des ressources critiques -->
<link rel="preload" href="/hero-image.webp" as="image" />
<link rel="preload" href="/fonts/main.woff2" as="font" type="font/woff2" crossorigin />
<!-- Preconnect aux origines tierces -->
<link rel="preconnect" href="https://fonts.googleapis.com" />
<link rel="preconnect" href="https://cdn.example.com" />
<!-- Priority hints -->
<img src="hero.webp" fetchpriority="high" alt="Hero" />
<script src="non-critical.js" fetchpriority="low"></script>
```
```css
/* Éviter le render-blocking CSS */
@media print {
/* Styles print non-bloquants */
}
/* Inline critical CSS */
<style>
/* CSS critique pour above-the-fold */
.hero { min-height: 100vh; }
</style>
```
```javascript
// Lazy load non-critical JS
const heavyModule = await import('./heavy-module.js');
// Defer non-critical scripts
<script src="analytics.js" defer></script>
```
### FID / INP (First Input Delay / Interaction to Next Paint)
Temps de réponse aux interactions utilisateur.
**Objectifs INP :**
- Bon : < 200ms
- À améliorer : 200ms - 500ms
- Mauvais : > 500ms
**Optimisations :**
```javascript
// Éviter le long tasks (> 50ms)
// ❌ Mauvais
function processLargeArray(items) {
items.forEach(item => heavyProcessing(item));
}
// ✅ Bon - Diviser en chunks
async function processLargeArrayChunked(items) {
const chunkSize = 100;
for (let i = 0; i < items.length; i += chunkSize) {
const chunk = items.slice(i, i + chunkSize);
chunk.forEach(item => heavyProcessing(item));
// Laisser le navigateur respirer
await new Promise(resolve => setTimeout(resolve, 0));
}
}
// Utiliser requestIdleCallback pour tâches non-critiques
function scheduleNonCriticalWork() {
requestIdleCallback((deadline) => {
while (deadline.timeRemaining() > 0 && tasks.length > 0) {
doTask(tasks.pop());
}
if (tasks.length > 0) {
scheduleNonCriticalWork();
}
});
}
// Web Workers pour calculs lourds
const worker = new Worker('/heavy-computation.js');
worker.postMessage(data);
worker.onmessage = (e) => {
updateUI(e.data);
};
```
### CLS (Cumulative Layout Shift)
Stabilité visuelle de la page.
**Objectifs :**
- Bon : < 0.1
- À améliorer : 0.1 - 0.25
- Mauvais : > 0.25
**Optimisations :**
```html
<!-- Toujours spécifier les dimensions -->
<img src="photo.jpg" width="800" height="600" alt="Photo" />
<video width="1280" height="720" poster="poster.jpg"></video>
<iframe width="560" height="315" src="..."></iframe>
<!-- Aspect ratio CSS -->
<style>
.image-container {
aspect-ratio: 16 / 9;
width: 100%;
}
.image-container img {
width: 100%;
height: 100%;
object-fit: cover;
}
</style>
```
```css
/* Réserver l'espace pour le contenu dynamique */
.ad-slot {
min-height: 250px;
}
.skeleton {
min-height: 200px;
background: linear-gradient(90deg, #f0f0f0 25%, #e0e0e0 50%, #f0f0f0 75%);
}
/* Éviter les font-swap non contrôlés */
@font-face {
font-family: 'MyFont';
src: url('font.woff2') format('woff2');
font-display: optional; /* ou swap avec fallback similaire */
}
```
```javascript
// Éviter d'insérer du contenu au-dessus du contenu existant
// ❌ Mauvais
container.insertBefore(newElement, container.firstChild);
// ✅ Bon - Ajouter à la fin ou réserver l'espace
container.appendChild(newElement);
```
## Outils de Mesure
### Lighthouse
```bash
# CLI
npx lighthouse https://example.com --output json --output-path ./report.json
# Avec options
npx lighthouse https://example.com \
--only-categories=performance \
--throttling.cpuSlowdownMultiplier=4 \
--chrome-flags="--headless"
```
```javascript
// API Node.js
const lighthouse = require('lighthouse');
const chromeLauncher = require('chrome-launcher');
async function runLighthouse(url) {
const chrome = await chromeLauncher.launch({ chromeFlags: ['--headless'] });
const options = {
logLevel: 'info',
output: 'json',
port: chrome.port,
};
const result = await lighthouse(url, options);
await chrome.kill();
return result.lhr;
}
```
### Web Vitals Library
```javascript
import { onLCP, onFID, onCLS, onINP, onTTFB } from 'web-vitals';
function sendToAnalytics({ name, value, rating, delta, id }) {
// Envoyer à votre service d'analytics
gtag('event', name, {
event_category: 'Web Vitals',
value: Math.round(name === 'CLS' ? value * 1000 : value),
event_label: id,
non_interaction: true,
});
}
onLCP(sendToAnalytics);
onFID(sendToAnalytics);
onCLS(sendToAnalytics);
onINP(sendToAnalytics);
onTTFB(sendToAnalytics);
```
### Performance Observer
```javascript
// Observer les Long Tasks
const observer = new PerformanceObserver((list) => {
for (const entry of list.getEntries()) {
console.log('Long Task detected:', entry.duration, 'ms');
}
});
observer.observe({ entryTypes: ['longtask'] });
// Observer le LCP
const lcpObserver = new PerformanceObserver((list) => {
const entries = list.getEntries();
const lastEntry = entries[entries.length - 1];
console.log('LCP:', lastEntry.startTime, 'ms');
console.log('LCP Element:', lastEntry.element);
});
lcpObserver.observe({ entryTypes: ['largest-contentful-paint'] });
// Observer les Layout Shifts
const clsObserver = new PerformanceObserver((list) => {
for (const entry of list.getEntries()) {
if (!entry.hadRecentInput) {
console.log('Layout Shift:', entry.value, entry.sources);
}
}
});
clsObserver.observe({ entryTypes: ['layout-shift'] });
```

# Agent React State
## Responsabilité
Maîtriser les solutions de gestion d'état pour React.
## Tu NE fais PAS
- ❌ Implémenter les hooks React généraux (useEffect, useRef, custom hooks) → skill `react-expert`
- ❌ Gérer le server state (React Query, SWR) → `server-state.md`
- ❌ Tester le state et les reducers → `testing/`
- ❌ Gérer le state backend (sessions, database) → skill `backend-developer`
## État Local
### useState pour valeurs simples
```tsx
const [count, setCount] = useState(0);
const [name, setName] = useState('');
const [isOpen, setIsOpen] = useState(false);
// Mise à jour basée sur état précédent
setCount((prev) => prev + 1);
// Lazy initialization
const [data, setData] = useState(() => computeExpensiveValue());
```
### useReducer pour état complexe
```tsx
interface State {
items: Item[];
isLoading: boolean;
error: Error | null;
filter: string;
}
type Action =
| { type: 'FETCH_START' }
| { type: 'FETCH_SUCCESS'; payload: Item[] }
| { type: 'FETCH_ERROR'; payload: Error }
| { type: 'SET_FILTER'; payload: string }
| { type: 'ADD_ITEM'; payload: Item }
| { type: 'REMOVE_ITEM'; payload: string };
function reducer(state: State, action: Action): State {
switch (action.type) {
case 'FETCH_START':
return { ...state, isLoading: true, error: null };
case 'FETCH_SUCCESS':
return { ...state, isLoading: false, items: action.payload };
case 'FETCH_ERROR':
return { ...state, isLoading: false, error: action.payload };
case 'SET_FILTER':
return { ...state, filter: action.payload };
case 'ADD_ITEM':
return { ...state, items: [...state.items, action.payload] };
case 'REMOVE_ITEM':
return {
...state,
items: state.items.filter((i) => i.id !== action.payload),
};
default:
return state;
}
}
const initialState: State = {
items: [],
isLoading: false,
error: null,
filter: '',
};
function ItemList() {
const [state, dispatch] = useReducer(reducer, initialState);
useEffect(() => {
dispatch({ type: 'FETCH_START' });
fetchItems()
.then((items) => dispatch({ type: 'FETCH_SUCCESS', payload: items }))
.catch((error) => dispatch({ type: 'FETCH_ERROR', payload: error }));
}, []);
return (/* ... */);
}
```
## Context API
### Pattern recommandé
```tsx
// contexts/AuthContext.tsx
interface User {
id: string;
name: string;
email: string;
}
interface AuthContextType {
user: User | null;
isAuthenticated: boolean;
isLoading: boolean;
login: (email: string, password: string) => Promise<void>;
logout: () => Promise<void>;
}
const AuthContext = createContext<AuthContextType | null>(null);
export function AuthProvider({ children }: { children: React.ReactNode }) {
const [user, setUser] = useState<User | null>(null);
const [isLoading, setIsLoading] = useState(true);
useEffect(() => {
// Vérifier la session au montage
checkSession()
.then(setUser)
.finally(() => setIsLoading(false));
}, []);
const login = async (email: string, password: string) => {
const user = await authAPI.login(email, password);
setUser(user);
};
const logout = async () => {
await authAPI.logout();
setUser(null);
};
const value = useMemo(
() => ({
user,
isAuthenticated: !!user,
isLoading,
login,
logout,
}),
[user, isLoading]
);
return <AuthContext.Provider value={value}>{children}</AuthContext.Provider>;
}
export function useAuth() {
const context = useContext(AuthContext);
if (!context) {
throw new Error('useAuth must be used within AuthProvider');
}
return context;
}
```
### Optimiser les re-renders
```tsx
// Séparer les contextes par fréquence de mise à jour
const UserContext = createContext<User | null>(null);
const UserActionsContext = createContext<UserActions | null>(null);
function UserProvider({ children }: { children: React.ReactNode }) {
const [user, setUser] = useState<User | null>(null);
// Actions stables (ne changent pas)
const actions = useMemo(
() => ({
updateName: (name: string) => setUser((u) => u ? { ...u, name } : null),
clear: () => setUser(null),
}),
[]
);
return (
<UserActionsContext.Provider value={actions}>
<UserContext.Provider value={user}>{children}</UserContext.Provider>
</UserActionsContext.Provider>
);
}
// Composants qui n'ont besoin que des actions ne re-render pas
// quand user change
function UserActions() {
const { updateName } = useContext(UserActionsContext)!;
return <button onClick={() => updateName('New')}>Update</button>;
}
```
## Zustand
### Installation
```bash
npm install zustand
```
### Store de base
```tsx
import { create } from 'zustand';
interface CounterStore {
count: number;
increment: () => void;
decrement: () => void;
reset: () => void;
}
const useCounterStore = create<CounterStore>((set) => ({
count: 0,
increment: () => set((state) => ({ count: state.count + 1 })),
decrement: () => set((state) => ({ count: state.count - 1 })),
reset: () => set({ count: 0 }),
}));
// Usage
function Counter() {
const count = useCounterStore((state) => state.count);
const increment = useCounterStore((state) => state.increment);
return (
<button onClick={increment}>
Count: {count}
</button>
);
}
```
### Store complexe avec middleware
```tsx
import { create } from 'zustand';
import { devtools, persist } from 'zustand/middleware';
import { immer } from 'zustand/middleware/immer';
interface Todo {
id: string;
text: string;
completed: boolean;
}
interface TodoStore {
todos: Todo[];
filter: 'all' | 'active' | 'completed';
addTodo: (text: string) => void;
toggleTodo: (id: string) => void;
removeTodo: (id: string) => void;
setFilter: (filter: TodoStore['filter']) => void;
}
const useTodoStore = create<TodoStore>()(
devtools(
persist(
immer((set) => ({
todos: [],
filter: 'all',
addTodo: (text) =>
set((state) => {
state.todos.push({
id: crypto.randomUUID(),
text,
completed: false,
});
}),
toggleTodo: (id) =>
set((state) => {
const todo = state.todos.find((t) => t.id === id);
if (todo) {
todo.completed = !todo.completed;
}
}),
removeTodo: (id) =>
set((state) => {
state.todos = state.todos.filter((t) => t.id !== id);
}),
setFilter: (filter) => set({ filter }),
})),
{ name: 'todo-storage' }
),
{ name: 'TodoStore' }
)
);
// Sélecteurs dérivés
const useFilteredTodos = () =>
useTodoStore((state) => {
switch (state.filter) {
case 'active':
return state.todos.filter((t) => !t.completed);
case 'completed':
return state.todos.filter((t) => t.completed);
default:
return state.todos;
}
});
```
### Slices pattern
```tsx
// stores/authSlice.ts
interface AuthSlice {
user: User | null;
isAuthenticated: boolean;
login: (user: User) => void;
logout: () => void;
}
const createAuthSlice: StateCreator<AuthSlice> = (set) => ({
user: null,
isAuthenticated: false,
login: (user) => set({ user, isAuthenticated: true }),
logout: () => set({ user: null, isAuthenticated: false }),
});
// stores/uiSlice.ts
interface UISlice {
theme: 'light' | 'dark';
sidebarOpen: boolean;
toggleTheme: () => void;
toggleSidebar: () => void;
}
const createUISlice: StateCreator<UISlice> = (set) => ({
theme: 'light',
sidebarOpen: true,
toggleTheme: () =>
set((state) => ({ theme: state.theme === 'light' ? 'dark' : 'light' })),
toggleSidebar: () => set((state) => ({ sidebarOpen: !state.sidebarOpen })),
});
// stores/index.ts
type StoreState = AuthSlice & UISlice;
const useStore = create<StoreState>()((...a) => ({
...createAuthSlice(...a),
...createUISlice(...a),
}));
```
## Redux Toolkit
### Configuration
```tsx
// store/store.ts
import { configureStore } from '@reduxjs/toolkit';
import counterReducer from './counterSlice';
import todosReducer from './todosSlice';
export const store = configureStore({
reducer: {
counter: counterReducer,
todos: todosReducer,
},
});
export type RootState = ReturnType<typeof store.getState>;
export type AppDispatch = typeof store.dispatch;
// hooks/store.ts
import { useDispatch, useSelector, TypedUseSelectorHook } from 'react-redux';
export const useAppDispatch = () => useDispatch<AppDispatch>();
export const useAppSelector: TypedUseSelectorHook<RootState> = useSelector;
```
### Slice avec createSlice
```tsx
// store/todosSlice.ts
import { createSlice, createAsyncThunk, PayloadAction } from '@reduxjs/toolkit';
interface Todo {
id: string;
text: string;
completed: boolean;
}
interface TodosState {
items: Todo[];
status: 'idle' | 'loading' | 'succeeded' | 'failed';
error: string | null;
}
const initialState: TodosState = {
items: [],
status: 'idle',
error: null,
};
// Async thunk
export const fetchTodos = createAsyncThunk('todos/fetchTodos', async () => {
const response = await fetch('/api/todos');
return response.json() as Promise<Todo[]>;
});
const todosSlice = createSlice({
name: 'todos',
initialState,
reducers: {
addTodo: (state, action: PayloadAction<string>) => {
state.items.push({
id: crypto.randomUUID(),
text: action.payload,
completed: false,
});
},
toggleTodo: (state, action: PayloadAction<string>) => {
const todo = state.items.find((t) => t.id === action.payload);
if (todo) {
todo.completed = !todo.completed;
}
},
removeTodo: (state, action: PayloadAction<string>) => {
state.items = state.items.filter((t) => t.id !== action.payload);
},
},
extraReducers: (builder) => {
builder
.addCase(fetchTodos.pending, (state) => {
state.status = 'loading';
})
.addCase(fetchTodos.fulfilled, (state, action) => {
state.status = 'succeeded';
state.items = action.payload;
})
.addCase(fetchTodos.rejected, (state, action) => {
state.status = 'failed';
state.error = action.error.message ?? 'Unknown error';
});
},
});
export const { addTodo, toggleTodo, removeTodo } = todosSlice.actions;
export default todosSlice.reducer;
// Sélecteurs
export const selectAllTodos = (state: RootState) => state.todos.items;
export const selectTodosStatus = (state: RootState) => state.todos.status;
export const selectActiveTodos = (state: RootState) =>
state.todos.items.filter((t) => !t.completed);
```

return (
<QueryClientProvider client={queryClient}>
{children}
<ReactQueryDevtools initialIsOpen={false} />
</QueryClientProvider>
);

```
### Queries de base
```tsx
import { useQuery } from '@tanstack/react-query';
// Query simple
function UserProfile({ userId }: { userId: string }) {
const { data, isLoading, error, refetch } = useQuery({
queryKey: ['user', userId],
queryFn: () => fetchUser(userId),

}
// Query avec options
const { data: posts } = useQuery({
queryKey: ['posts', { page, limit, filter }],
queryFn: () => fetchPosts({ page, limit, filter }),
enabled: !!userId, // Query conditionnelle
staleTime: 1000 * 60 * 10, // 10 minutes

});
// Query avec retry personnalisé
const { data } = useQuery({
queryKey: ['critical-data'],
queryFn: fetchCriticalData,
retry: (failureCount, error) => {
if (error.status === 404) return false;

const queryClient = useQueryClient();
const mutation = useMutation({
mutationFn: (newPost: CreatePostInput) => createPost(newPost),
onSuccess: (data) => {
// Invalider et refetch les posts
queryClient.invalidateQueries({ queryKey: ['posts'] });
// Ou mise à jour optimiste du cache

const queryClient = useQueryClient();
const deleteMutation = useMutation({
mutationFn: (todoId: string) => deleteTodo(todoId),
onMutate: async (todoId) => {
// Annuler les queries en cours
await queryClient.cancelQueries({ queryKey: ['todos'] });
// Snapshot de l'état actuel
const previousTodos = queryClient.getQueryData<Todo[]>(['todos']);
// Mise à jour optimiste
queryClient.setQueryData<Todo[]>(['todos'], (old) =>
old?.filter((t) => t.id !== todoId)
);
// Retourner le snapshot pour rollback
return { previousTodos };
},
onError: (err, todoId, context) => {
// Rollback en cas d'erreur
queryClient.setQueryData(['todos'], context?.previousTodos);
},
onSettled: () => {
// Refetch pour s'assurer de la synchronisation
queryClient.invalidateQueries({ queryKey: ['todos'] });
},
});
```
### Queries parallèles et dépendantes
```tsx
// Queries parallèles
function Dashboard() {
const results = useQueries({
queries: [
{ queryKey: ['users'], queryFn: fetchUsers },
{ queryKey: ['posts'], queryFn: fetchPosts },
{ queryKey: ['comments'], queryFn: fetchComments },
],
});
const isLoading = results.some((r) => r.isLoading);
const [users, posts, comments] = results.map((r) => r.data);
return (/* ... */);
}
// Queries dépendantes
function UserPosts({ userId }: { userId: string }) {
const userQuery = useQuery({
queryKey: ['user', userId],
queryFn: () => fetchUser(userId),
});
const postsQuery = useQuery({
queryKey: ['posts', userQuery.data?.id],
queryFn: () => fetchPostsByUser(userQuery.data!.id),
enabled: !!userQuery.data?.id, // Attend que user soit chargé
});
return (/* ... */);
}
```
### Infinite Queries
```tsx
import { useInfiniteQuery } from '@tanstack/react-query';
function InfinitePostsList() {
const {
data,
fetchNextPage,
hasNextPage,
isFetchingNextPage,
} = useInfiniteQuery({
queryKey: ['posts', 'infinite'],
queryFn: ({ pageParam }) => fetchPosts({ cursor: pageParam }),
initialPageParam: null as string | null,
getNextPageParam: (lastPage) => lastPage.nextCursor,
});
const allPosts = data?.pages.flatMap((page) => page.posts) ?? [];
return (
<>
{allPosts.map((post) => (
<PostCard key={post.id} post={post} />
))}
<button
onClick={() => fetchNextPage()}
disabled={!hasNextPage || isFetchingNextPage}
>
{isFetchingNextPage
? 'Chargement...'
: hasNextPage
? 'Charger plus'
: 'Fin'}
</button>
</>
);
}
```
## SWR
### Installation et configuration
```bash
npm install swr
```
```tsx
import useSWR, { SWRConfig } from 'swr';
const fetcher = (url: string) => fetch(url).then((res) => res.json());
function App() {
return (
<SWRConfig
value={{
fetcher,
revalidateOnFocus: true,
revalidateOnReconnect: true,
dedupingInterval: 2000,
}}
>
<Content />
</SWRConfig>
);
}
```
### Usage de base
```tsx
import useSWR from 'swr';
function UserProfile({ userId }: { userId: string }) {
const { data, error, isLoading, mutate } = useSWR<User>(
`/api/users/${userId}`,
fetcher
);
if (isLoading) return <Skeleton />;
if (error) return <Error />;
return (
<div>
<h1>{data.name}</h1>
<button onClick={() => mutate()}>Refresh</button>
</div>
);
}
```
### Mutation avec SWR
```tsx
import useSWRMutation from 'swr/mutation';
async function createPost(url: string, { arg }: { arg: CreatePostInput }) {
const res = await fetch(url, {
method: 'POST',
body: JSON.stringify(arg),
});
return res.json();
}
function CreatePostForm() {
const { trigger, isMutating } = useSWRMutation('/api/posts', createPost);
const handleSubmit = async (data: CreatePostInput) => {
try {
await trigger(data);
toast.success('Post créé!');
} catch (error) {
toast.error('Erreur');
}
};
return (/* ... */);
}
// Mutation optimiste
import { useSWRConfig } from 'swr';
function DeleteButton({ postId }: { postId: string }) {
const { mutate } = useSWRConfig();
const handleDelete = async () => {
// Mise à jour optimiste
mutate(
'/api/posts',
(posts: Post[]) => posts.filter((p) => p.id !== postId),
false // Ne pas revalider tout de suite
);
try {
await deletePost(postId);
mutate('/api/posts'); // Revalider après succès
} catch {
mutate('/api/posts'); // Rollback via revalidation
}
};
return <button onClick={handleDelete}>Supprimer</button>;
}
```
### Patterns avancés SWR
```tsx
// Requête conditionnelle
const { data } = useSWR(userId ? `/api/users/${userId}` : null);
// Dépendances
const { data: user } = useSWR('/api/user');
const { data: projects } = useSWR(() => `/api/projects?uid=${user.id}`);
// Revalidation périodique
const { data } = useSWR('/api/data', fetcher, {
refreshInterval: 3000, // Toutes les 3 secondes
});
// Données locales avec fallback
const { data } = useSWR('/api/data', fetcher, {
fallbackData: localData,
});
```
## Bonnes Pratiques
### Factory de query keys
```tsx
// keys.ts
export const userKeys = {
all: ['users'] as const,
lists: () => [...userKeys.all, 'list'] as const,
list: (filters: UserFilters) => [...userKeys.lists(), filters] as const,
details: () => [...userKeys.all, 'detail'] as const,
detail: (id: string) => [...userKeys.details(), id] as const,
};
// Usage
useQuery({
queryKey: userKeys.detail(userId),
queryFn: () => fetchUser(userId),
});
// Invalidation ciblée
queryClient.invalidateQueries({ queryKey: userKeys.lists() });
```
### Custom hooks
```tsx
// hooks/useUser.ts
export function useUser(userId: string) {
return useQuery({
queryKey: userKeys.detail(userId),
queryFn: () => fetchUser(userId),
staleTime: 1000 * 60 * 5,
});
}
export function useUpdateUser() {
const queryClient = useQueryClient();
return useMutation({
mutationFn: updateUser,
onSuccess: (data) => {
queryClient.setQueryData(userKeys.detail(data.id), data);
},
});
}
```

/* Transitions multiples */
transition:
background-color 0.3s ease,
transform 0.2s ease-out;
/* Shorthand */
transition: all 0.3s ease;
}
.button:hover {
background-color: #0051a2;
transform: scale(1.05);
}
```
### Timing Functions
```css
/* Fonctions prédéfinies */
transition-timing-function: ease; /* Défaut */

## Styled-Components
### Installation et setup
```bash
npm install styled-components
npm install -D @types/styled-components # TypeScript
```
### Composants de base
```tsx
import styled from 'styled-components';
// Composant simple
const Button = styled.button`
background-color: #0070f3;
color: white;
padding: 0.75rem 1.5rem;
border: none;
border-radius: 8px;
font-size: 1rem;
cursor: pointer;
transition: background-color 0.2s;
&:hover {
background-color: #0051a2;
}
&:disabled {
opacity: 0.5;
cursor: not-allowed;
}
`;
// Avec props
interface ButtonProps {
variant?: 'primary' | 'secondary';
size?: 'sm' | 'md' | 'lg';
}
const StyledButton = styled.button<ButtonProps>`
padding: ${({ size }) => {
switch (size) {
case 'sm': return '0.5rem 1rem';
case 'lg': return '1rem 2rem';
default: return '0.75rem 1.5rem';
}
}};
background-color: ${({ variant }) =>
variant === 'secondary' ? '#e5e7eb' : '#0070f3'};
color: ${({ variant }) =>
variant === 'secondary' ? '#374151' : 'white'};
`;
```
### Thèmes
```tsx
import { ThemeProvider, createGlobalStyle } from 'styled-components';
// Définition du thème
const theme = {
colors: {
primary: '#0070f3',
secondary: '#6b7280',
background: '#ffffff',
text: '#111827',
error: '#ef4444',
},
spacing: {
xs: '0.25rem',
sm: '0.5rem',
md: '1rem',
lg: '2rem',
xl: '4rem',
},
borderRadius: {
sm: '4px',
md: '8px',
lg: '16px',
full: '9999px',
},
shadows: {
sm: '0 1px 2px rgba(0, 0, 0, 0.05)',

box-sizing: border-box;
}
body {
margin: 0;
font-family: system-ui, sans-serif;
background-color: ${({ theme }) => theme.colors.background};
color: ${({ theme }) => theme.colors.text};
}
`;
// Usage dans l'app
function App() {
return (
<ThemeProvider theme={theme}>
<GlobalStyle />
<Content />
</ThemeProvider>
);
}
// Accès au thème dans les composants
const Card = styled.div`
background: ${({ theme }) => theme.colors.background};
padding: ${({ theme }) => theme.spacing.lg};
border-radius: ${({ theme }) => theme.borderRadius.md};
box-shadow: ${({ theme }) => theme.shadows.md};
`;
```
### Patterns avancés
```tsx
// Extension de composant
const PrimaryButton = styled(Button)`
background-color: #0070f3;
`;
// Cibler un autre composant
const Icon = styled.span`
margin-right: 0.5rem;
`;
const ButtonWithIcon = styled.button`
${Icon} {
transition: transform 0.2s;
}
&:hover ${Icon} {
transform: translateX(4px);
}
`;
// Attributs par défaut
const SubmitButton = styled.button.attrs({
type: 'submit',
})`
/* styles */
`;
// Polymorphisme avec "as"
const Heading = styled.h1`
font-size: 2rem;
font-weight: bold;
`;
// Rendu en h2
<Heading as="h2">Sous-titre</Heading>
// CSS helper
import { css } from 'styled-components';
const flexCenter = css`
display: flex;
justify-content: center;
align-items: center;
`;
const CenteredBox = styled.div`
${flexCenter}
height: 100vh;
`;
```
## Emotion
### Installation
```bash
npm install @emotion/react @emotion/styled
```
### Syntaxe styled (similaire à styled-components)
```tsx
import styled from '@emotion/styled';
const Button = styled.button`
background: #0070f3;
color: white;
padding: 0.75rem 1.5rem;
`;
```
### Syntaxe css prop
```tsx
/** @jsxImportSource @emotion/react */
import { css } from '@emotion/react';
function Component() {
return (
<div
css={css`
padding: 1rem;
background: white;
border-radius: 8px;
`}
>
Content
</div>
);
}
// Avec objet (meilleure performance)
function ComponentObject() {
return (
<div
css={{
padding: '1rem',
background: 'white',
borderRadius: '8px',
}}
>
Content
</div>
);
}
```
### Composition de styles
```tsx
import { css, SerializedStyles } from '@emotion/react';
const baseButton = css`
padding: 0.75rem 1.5rem;
border-radius: 8px;
font-weight: 500;
transition: all 0.2s;
`;
const primaryStyle = css`
${baseButton}
background: #0070f3;
color: white;
&:hover {
background: #0051a2;
}
`;
const secondaryStyle = css`
${baseButton}
background: #e5e7eb;
color: #374151;
`;
function Button({ variant = 'primary' }: { variant?: 'primary' | 'secondary' }) {
return (
<button css={variant === 'primary' ? primaryStyle : secondaryStyle}>
Click me
</button>
);
}
```
## CSS Modules
### Configuration
```css
/* Button.module.css */
.button {
padding: 0.75rem 1.5rem;
border-radius: 8px;
cursor: pointer;
}
.primary {
composes: button;
background-color: #0070f3;
color: white;
}
.secondary {
composes: button;
background-color: #e5e7eb;
color: #374151;
}
.large {
padding: 1rem 2rem;
font-size: 1.125rem;
}
/* Variables CSS locales */
.card {
--card-padding: 1.5rem;
padding: var(--card-padding);
}
```
### Usage React
```tsx
import styles from './Button.module.css';
import clsx from 'clsx';
interface ButtonProps {
variant?: 'primary' | 'secondary';
size?: 'md' | 'lg';
children: React.ReactNode;
}
function Button({ variant = 'primary', size = 'md', children }: ButtonProps) {
return (
<button
className={clsx(
styles[variant],
size === 'lg' && styles.large
)}
>
{children}
</button>
);
}
```
### TypeScript avec CSS Modules
```typescript
// types/css-modules.d.ts
declare module '*.module.css' {
const classes: { [key: string]: string };
export default classes;
}
declare module '*.module.scss' {
const classes: { [key: string]: string };
export default classes;
}
```
### CSS Modules avec SCSS
```scss
// Card.module.scss
@use 'sass:color';
$primary-color: #0070f3;
.card {
padding: 1.5rem;
border-radius: 12px;
box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1);
&:hover {
box-shadow: 0 10px 15px rgba(0, 0, 0, 0.1);
}
}
.header {
border-bottom: 1px solid color.adjust($primary-color, $lightness: 40%);

## Comparaison des Solutions
| Feature | styled-components | Emotion | CSS Modules |
|---------|------------------|---------|-------------|
| Runtime | Oui | Oui | Non |
| Bundle size | ~12kb | ~11kb | 0kb |
| SSR | Besoin de config | Besoin de config | Natif |
| Theming | Intégré | Intégré | Variables CSS |
| TypeScript | Bon | Excellent | Via typings |
| Performance | Bonne | Meilleure | Excellente |
| Dynamic styles | Oui | Oui | Limité |
## Bonnes Pratiques
### Performance
```tsx
// ❌ Éviter les styles inline dynamiques
const Component = ({ color }) => (
<div style={{ backgroundColor: color }} />
);
// ✅ Utiliser des classes/variants
const StyledDiv = styled.div<{ $color: string }>`
background-color: ${({ $color }) => $color};
`;
// ❌ Éviter de créer des styled dans le render
function Component() {
const Button = styled.button`...`; // Recréé à chaque render!
return <Button />;
}
// ✅ Définir les styled à l'extérieur
const Button = styled.button`...`;
function Component() {
return <Button />;
}
```
### Organisation
```

variant?: 'primary' | 'secondary' | 'outline';
size?: 'sm' | 'md' | 'lg';
}
function Button({
variant = 'primary',
size = 'md',
className,
...props
}: ButtonProps) {
return (
<button
className={cn(
// Base

# Agent Component Testing
## Responsabilité
Maîtriser les tests de composants React et Vue avec les bibliothèques de test officielles.
## Tu NE fais PAS
- ❌ Écrire des tests E2E (parcours complets) → `e2e-testing.md`
- ❌ Tester la logique pure (fonctions utils) → `unit-testing.md`
- ❌ Gérer Storybook et tests visuels → Visual testing si disponible
- ❌ Définir la stratégie de test → skill `testing-process`
## React Testing Library
### Principes fondamentaux
> "The more your tests resemble the way your software is used, the more confidence they can give you."
- Tester le comportement, pas l'implémentation
- Utiliser des sélecteurs accessibles (role, label, text)
- Éviter les détails d'implémentation (state, props internes)
### Queries prioritaires
```typescript
// 1. Accessible à tous (préférés)
getByRole('button', { name: /submit/i });
getByLabelText(/email/i);
getByPlaceholderText(/enter your name/i);
getByText(/learn more/i);
getByDisplayValue('current value');
// 2. Sémantique
getByAltText(/logo/i);
getByTitle(/tooltip/i);
// 3. Test ID (dernier recours)
getByTestId('custom-element');
```
### Variantes de queries
```typescript
// getBy - Erreur si non trouvé
const button = screen.getByRole('button');
// queryBy - Null si non trouvé (utile pour vérifier absence)
const modal = screen.queryByRole('dialog');
expect(modal).not.toBeInTheDocument();
// findBy - Async, attend l'élément
const message = await screen.findByText(/success/i);
// getAllBy, queryAllBy, findAllBy - Pour multiples éléments
const items = screen.getAllByRole('listitem');
```
### Tests de base
```typescript
import { render, screen } from '@testing-library/react';
import userEvent from '@testing-library/user-event';
import { describe, it, expect } from 'vitest';
import { Button } from './Button';
describe('Button', () => {
it('renders with text', () => {
render(<Button>Click me</Button>);
expect(screen.getByRole('button', { name: /click me/i })).toBeInTheDocument();
});
it('calls onClick when clicked', async () => {
const user = userEvent.setup();
const handleClick = vi.fn();
render(<Button onClick={handleClick}>Click me</Button>);
await user.click(screen.getByRole('button'));
expect(handleClick).toHaveBeenCalledTimes(1);
});
it('is disabled when disabled prop is true', () => {
render(<Button disabled>Click me</Button>);
expect(screen.getByRole('button')).toBeDisabled();
});
it('applies variant styles', () => {
render(<Button variant="primary">Primary</Button>);
expect(screen.getByRole('button')).toHaveClass('btn-primary');
});
});
```
### Interactions utilisateur
```typescript
import { render, screen } from '@testing-library/react';
import userEvent from '@testing-library/user-event';
import { LoginForm } from './LoginForm';
describe('LoginForm', () => {
it('submits form with user data', async () => {
const user = userEvent.setup();
const onSubmit = vi.fn();
render(<LoginForm onSubmit={onSubmit} />);
// Remplir le formulaire
await user.type(screen.getByLabelText(/email/i), 'test@example.com');
await user.type(screen.getByLabelText(/password/i), 'password123');
// Soumettre
await user.click(screen.getByRole('button', { name: /sign in/i }));
expect(onSubmit).toHaveBeenCalledWith({
email: 'test@example.com',
password: 'password123',
});
});
it('shows validation errors', async () => {
const user = userEvent.setup();
render(<LoginForm onSubmit={vi.fn()} />);
// Soumettre formulaire vide
await user.click(screen.getByRole('button', { name: /sign in/i }));
expect(screen.getByText(/email is required/i)).toBeInTheDocument();
expect(screen.getByText(/password is required/i)).toBeInTheDocument();
});
it('clears input on clear button click', async () => {
const user = userEvent.setup();
render(<LoginForm onSubmit={vi.fn()} />);
const emailInput = screen.getByLabelText(/email/i);
await user.type(emailInput, 'test@example.com');
await user.clear(emailInput);
expect(emailInput).toHaveValue('');
});
});
```
### Test avec providers
```typescript
import { render, screen } from '@testing-library/react';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { BrowserRouter } from 'react-router-dom';
import { ThemeProvider } from './ThemeContext';
// Wrapper personnalisé
function createWrapper() {
const queryClient = new QueryClient({
defaultOptions: {
queries: { retry: false },
},
});
return function Wrapper({ children }: { children: React.ReactNode }) {
return (
<QueryClientProvider client={queryClient}>
<BrowserRouter>
<ThemeProvider>{children}</ThemeProvider>
</BrowserRouter>
</QueryClientProvider>
);
};
}
// Render helper
function renderWithProviders(ui: React.ReactElement) {
return render(ui, { wrapper: createWrapper() });
}
describe('Dashboard', () => {
it('renders with providers', async () => {
renderWithProviders(<Dashboard />);
expect(await screen.findByText(/dashboard/i)).toBeInTheDocument();
});
});
```
### Test async et attentes
```typescript
import { render, screen, waitFor, waitForElementToBeRemoved } from '@testing-library/react';
describe('async behavior', () => {
it('shows loading then data', async () => {
render(<DataLoader />);
// Vérifie le loading
expect(screen.getByText(/loading/i)).toBeInTheDocument();
// Attend que les données apparaissent
expect(await screen.findByText(/data loaded/i)).toBeInTheDocument();
// Le loading a disparu
expect(screen.queryByText(/loading/i)).not.toBeInTheDocument();
});
it('waits for element to be removed', async () => {
render(<Modal onClose={vi.fn()} />);
await userEvent.click(screen.getByRole('button', { name: /close/i }));
await waitForElementToBeRemoved(() => screen.queryByRole('dialog'));
});
it('uses waitFor for complex conditions', async () => {
render(<ComplexComponent />);
await waitFor(() => {
expect(screen.getByRole('list')).toBeInTheDocument();
expect(screen.getAllByRole('listitem')).toHaveLength(5);
});
});
});
```
### Mock de hooks personnalisés
```typescript
import { vi } from 'vitest';
import * as hooks from './hooks';
describe('component with custom hook', () => {
it('mocks useAuth hook', () => {
vi.spyOn(hooks, 'useAuth').mockReturnValue({
user: { id: '1', name: 'John' },
isAuthenticated: true,
login: vi.fn(),
logout: vi.fn(),
});
render(<ProtectedComponent />);
expect(screen.getByText(/welcome, john/i)).toBeInTheDocument();
});
});
```
### Test d'accessibilité
```typescript
import { render } from '@testing-library/react';
import { axe, toHaveNoViolations } from 'jest-axe';
expect.extend(toHaveNoViolations);
describe('accessibility', () => {
it('has no accessibility violations', async () => {
const { container } = render(<Form />);
const results = await axe(container);
expect(results).toHaveNoViolations();
});
it('has proper ARIA attributes', () => {
render(<Modal isOpen title="Confirmation" />);
const dialog = screen.getByRole('dialog');
expect(dialog).toHaveAttribute('aria-labelledby');
expect(dialog).toHaveAttribute('aria-modal', 'true');
});
});
```
## Vue Test Utils
```typescript
import { mount, shallowMount } from '@vue/test-utils';
import { describe, it, expect, vi } from 'vitest';
import Button from './Button.vue';
describe('Button.vue', () => {
it('renders slot content', () => {
const wrapper = mount(Button, {
slots: {
default: 'Click me',
},
});
expect(wrapper.text()).toContain('Click me');
});
it('emits click event', async () => {
const wrapper = mount(Button);
await wrapper.trigger('click');
expect(wrapper.emitted('click')).toHaveLength(1);
});
it('applies variant class', () => {
const wrapper = mount(Button, {
props: {
variant: 'primary',
},
});
expect(wrapper.classes()).toContain('btn-primary');
});
it('is disabled when prop is true', () => {
const wrapper = mount(Button, {
props: { disabled: true },
});
expect(wrapper.attributes('disabled')).toBeDefined();
});
});
describe('Form.vue', () => {
it('validates and submits', async () => {
const wrapper = mount(Form);
await wrapper.find('input[name="email"]').setValue('test@example.com');
await wrapper.find('form').trigger('submit');
expect(wrapper.emitted('submit')).toBeTruthy();
expect(wrapper.emitted('submit')[0]).toEqual([
{ email: 'test@example.com' },
]);

describe('Authentication', () => {
beforeEach(() => {
cy.visit('/login');
});
it('should login successfully', () => {
cy.get('[data-cy=email]').type('user@example.com');

});
```
## Bonnes Pratiques E2E
1. **Sélecteurs robustes** : Utiliser role, label, data-testid
2. **Isolation** : Chaque test doit être indépendant
3. **Données de test** : Utiliser des fixtures, éviter les données partagées
4. **Attentes explicites** : Éviter les timeouts arbitraires
5. **Retry** : Configurer les retries pour la CI
6. **Parallélisation** : Exécuter les tests en parallèle

branches: 80,
functions: 80,
lines: 80,
statements: 80,
},
},
};
```
## Structure des Tests
### Pattern AAA (Arrange, Act, Assert)
```typescript
import { describe, it, expect, beforeEach } from 'vitest';
import { calculateTotal, formatCurrency } from './utils';
describe('calculateTotal', () => {
// Arrange - données communes
const items = [
{ price: 10, quantity: 2 },
{ price: 5, quantity: 3 },
];
it('should calculate total correctly', () => {
// Act
const result = calculateTotal(items);
// Assert
expect(result).toBe(35);
});
it('should return 0 for empty array', () => {
expect(calculateTotal([])).toBe(0);
});
it('should handle single item', () => {
const single = [{ price: 10, quantity: 1 }];
expect(calculateTotal(single)).toBe(10);
});
});
describe('formatCurrency', () => {
it.each([
[1000, '$1,000.00'],
[999.99, '$999.99'],
[0, '$0.00'],
[-100, '-$100.00'],
])('should format %d as %s', (input, expected) => {
expect(formatCurrency(input)).toBe(expected);
});
});
```
### Test de fonctions async
```typescript
import { describe, it, expect, vi } from 'vitest';
import { fetchUser, processData } from './api';
describe('async functions', () => {
it('should fetch user data', async () => {
const user = await fetchUser('123');
expect(user).toEqual({
id: '123',
name: expect.any(String),
});
});
it('should handle errors', async () => {
await expect(fetchUser('invalid')).rejects.toThrow('User not found');
});
it('should process data with callback', () => {
return new Promise<void>((resolve) => {
processData((result) => {
expect(result).toBeDefined();
resolve();
});
});
});
});
```
## Mocking
### Mock de modules
```typescript
import { describe, it, expect, vi, beforeEach } from 'vitest';
import { fetchUsers } from './userService';
import * as api from './api';
// Mock le module entier
vi.mock('./api');
describe('userService', () => {
beforeEach(() => {
vi.clearAllMocks();
});
it('should fetch and transform users', async () => {
// Arrange
const mockUsers = [{ id: '1', name: 'John' }];
vi.mocked(api.get).mockResolvedValue(mockUsers);
// Act
const result = await fetchUsers();
// Assert
expect(api.get).toHaveBeenCalledWith('/users');
expect(result).toEqual(mockUsers);
});
it('should handle API errors', async () => {
vi.mocked(api.get).mockRejectedValue(new Error('Network error'));
await expect(fetchUsers()).rejects.toThrow('Network error');
});
});
```
### Mock partiel
```typescript
import { vi } from 'vitest';
// Mock partiel - garde les vraies implémentations
vi.mock('./utils', async () => {
const actual = await vi.importActual<typeof import('./utils')>('./utils');
return {
...actual,
expensiveOperation: vi.fn(() => 'mocked'),
};
});
```
### Spy sur méthodes
```typescript
import { describe, it, expect, vi } from 'vitest';
describe('spies', () => {
it('should spy on console.log', () => {
const consoleSpy = vi.spyOn(console, 'log');
console.log('test message');
expect(consoleSpy).toHaveBeenCalledWith('test message');
consoleSpy.mockRestore();
});
it('should spy on object method', () => {
const obj = {
method: () => 'original',
};
const spy = vi.spyOn(obj, 'method').mockReturnValue('mocked');
expect(obj.method()).toBe('mocked');
expect(spy).toHaveBeenCalled();
});
});
```
### Mock de timers
```typescript
import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';
import { debounce, delay } from './timing';
describe('timing functions', () => {
beforeEach(() => {
vi.useFakeTimers();
});
afterEach(() => {
vi.useRealTimers();
});
it('should delay execution', async () => {
const callback = vi.fn();
delay(callback, 1000);
expect(callback).not.toHaveBeenCalled();
vi.advanceTimersByTime(1000);
expect(callback).toHaveBeenCalledTimes(1);
});
it('should debounce calls', () => {
const fn = vi.fn();
const debounced = debounce(fn, 300);
debounced();
debounced();
debounced();
expect(fn).not.toHaveBeenCalled();
vi.runAllTimers();
expect(fn).toHaveBeenCalledTimes(1);
});
});
```
## Test de Hooks React
```typescript
import { renderHook, act } from '@testing-library/react';
import { describe, it, expect } from 'vitest';
import { useCounter, useAsync } from './hooks';
describe('useCounter', () => {
it('should initialize with default value', () => {
const { result } = renderHook(() => useCounter());
expect(result.current.count).toBe(0);
});
it('should initialize with custom value', () => {
const { result } = renderHook(() => useCounter(10));
expect(result.current.count).toBe(10);
});
it('should increment', () => {
const { result } = renderHook(() => useCounter());
act(() => {
result.current.increment();
});
expect(result.current.count).toBe(1);
});
it('should update on rerender with new props', () => {
const { result, rerender } = renderHook(
({ initial }) => useCounter(initial),
{ initialProps: { initial: 0 } }
);
expect(result.current.count).toBe(0);
rerender({ initial: 10 });
// Selon l'implémentation du hook
expect(result.current.count).toBe(10);
});
});
describe('useAsync', () => {
it('should handle async data', async () => {
const mockFetch = vi.fn().mockResolvedValue({ data: 'test' });
const { result } = renderHook(() => useAsync(mockFetch));
expect(result.current.isLoading).toBe(true);
await waitFor(() => {
expect(result.current.isLoading).toBe(false);
});
expect(result.current.data).toEqual({ data: 'test' });
});
});
```
## Matchers Courants
```typescript
// Égalité
expect(value).toBe(exact); // ===
expect(value).toEqual(deepEqual); // deep equality
expect(value).toStrictEqual(strictDeep); // + undefined props
// Truthiness
expect(value).toBeTruthy();
expect(value).toBeFalsy();
expect(value).toBeNull();
expect(value).toBeUndefined();
expect(value).toBeDefined();
// Nombres
expect(num).toBeGreaterThan(3);
expect(num).toBeGreaterThanOrEqual(3);
expect(num).toBeLessThan(5);
expect(num).toBeCloseTo(0.3, 5); // floating point
// Strings
expect(str).toMatch(/pattern/);
expect(str).toContain('substring');
// Arrays
expect(arr).toContain(item);
expect(arr).toContainEqual({ id: 1 });
expect(arr).toHaveLength(3);
// Objects
expect(obj).toHaveProperty('key');
expect(obj).toHaveProperty('nested.key', 'value');
expect(obj).toMatchObject({ partial: 'match' });
// Exceptions
expect(() => fn()).toThrow();
expect(() => fn()).toThrow('message');
expect(() => fn()).toThrow(ErrorClass);
// Mock assertions
expect(mock).toHaveBeenCalled();
expect(mock).toHaveBeenCalledTimes(2);
expect(mock).toHaveBeenCalledWith(arg1, arg2);
expect(mock).toHaveBeenLastCalledWith(arg);
```

## Règles de Routage
### Depuis direction-technique (POURQUOI)
| Question stratégique | Ce skill fournit |
|---------------------|------------------|
| "Quel framework choisir ?" | → direction-technique décide, puis ce skill implémente |
| "Architecture micro-frontend ?" | → direction-technique décide, puis ce skill code |
| "Stratégie de performance ?" | → direction-technique définit, ce skill optimise |
### Depuis web-dev-process (QUOI)
| Process défini | Ce skill implémente |
|----------------|---------------------|
| "Pyramide de tests" | → Code des tests (unit, component, e2e) |
| "Code review checklist" | → Implémente les bonnes pratiques |
| "Workflow CI/CD" | → Configure les outils |

## Points d'Escalade
### Vers direction-technique
- Choix de framework (React vs Vue vs Angular)
- Architecture globale (monolith vs micro-frontend)
- Décisions impactant toute l'équipe
- Trade-offs majeurs (performance vs maintenabilité)
### Vers web-dev-process
- Organisation du workflow de test
- Process de code review
- Standards de documentation
- Conventions d'équipe
### Vers l'humain
- Intégration avec systèmes legacy non documentés
- Contraintes techniques inhabituelles
- Bugs complexes sans solution évidente
