+
+## 4.5 Frontend
+
+L'interface utilisateur de Memegoat a été développée avec **Next.js**, en tirant parti des dernières avancées de l'écosystème React pour offrir une expérience fluide, performante et accessible.
 
 ### F.1 - Stack technique (Next.js 16, React 19, Tailwind CSS 4)
-
 L'interface de Memegoat repose sur une stack à la pointe de l'écosystème web, choisie pour ses performances et sa maintenabilité :
 - **Next.js 16 (App Router)** : Utilisation du framework de référence pour React, permettant un rendu hybride. Les pages sont pré-rendues côté serveur (SSR) pour le SEO, tandis que les interactions dynamiques sont gérées côté client.
-- **React 19** : Cette version majeure introduit des améliorations significatives, notamment dans la gestion des formulaires avec les **Server Actions** et le support natif de l'asynchronisme, réduisant drastiquement le code "boilerplate" de gestion d'état.

-- **Tailwind CSS 4** : La nouvelle itération de ce framework "Utility-First" offre une compilation plus rapide et une syntaxe simplifiée, permettant de construire des interfaces complexes sans quitter le fichier HTML/JSX.
+- **Tailwind CSS 4** : La nouvelle itération de ce framework "Utility-First" offre une compilation ultra-rapide et une configuration simplifiée via CSS-native variables, permettant de construire des interfaces complexes sans quitter le fichier HTML/JSX.
 
 ### F.2 - Architecture et Interfaces
-
+L'architecture frontend suit les principes de la **composabilité** et de la séparation des responsabilités. Le frontend est organisé en composants réutilisables, suivant les principes de l'**Atomic Design**.
-L'architecture frontend suit les principes de la **composabilité** et de la séparation des responsabilités.
+- **Composants et Design System** : Le projet utilise **Shadcn UI**, basé sur **Radix UI**, pour fournir une bibliothèque de composants non stylés mais hautement accessibles.
-
+- **Type-Safety** : Les interfaces TypeScript sont partagées avec le backend, garantissant que les données affichées correspondent exactement aux données envoyées par l'API.
-#### Composants et Design System
+- **Rendu Hybride** : Nous tirons pleinement parti des **React Server Components (RSC)**. Contrairement aux approches traditionnelles où tout le JavaScript est envoyé au client, les RSC permettent d'exécuter la logique lourde directement sur le serveur.
-Le projet utilise **Shadcn UI**, basé sur **Radix UI**, pour fournir une bibliothèque de composants non stylés mais hautement accessibles. Cela garantit que chaque bouton, menu ou fenêtre modale respecte les standards WAI-ARIA sans effort supplémentaire. Le design system est centralisé dans la configuration Tailwind, assurant une cohérence visuelle parfaite sur l'ensemble du site.
-
-#### Rendu Hybride et Performance
-Nous tirons pleinement parti des **React Server Components (RSC)**. Contrairement aux approches traditionnelles où tout le JavaScript est envoyé au client, les RSC permettent d'exécuter la logique lourde et les requêtes à la base de données directement sur le serveur. Le client ne reçoit que le HTML final et le JavaScript strictement nécessaire à l'interactivité, améliorant considérablement le **Time to Interactive (TTI)**.
 
 ### F.3 - Interface dynamique et UX
-
+L'expérience utilisateur est au cœur du développement :
-#### Flux de données et Server Actions
+- **Flux de données et Server Actions** : Pour les mutations de données (comme le partage d'un mème ou l'ajout aux favoris), Memegoat utilise les **Server Actions**, simplifiant l'architecture en éliminant le besoin de définir manuellement des API routes dédiées.
-Pour les mutations de données (comme le partage d'un mème ou l'ajout aux favoris), Memegoat utilise les **Server Actions**. Cette technologie permet d'appeler des fonctions serveur directement depuis des composants client, avec une gestion intégrée des états de chargement et des erreurs. Cela simplifie l'architecture en éliminant le besoin de définir manuellement des API routes dédiées pour chaque petite interaction.
+- **Optimistic Updates** : Pour des actions comme la mise en favoris, l'interface réagit instantanément avant même la confirmation du serveur, renforçant la sensation de fluidité.
-
+- **Streaming et Suspense** : L'utilisation de placeholders animés (**Skeletons**) pendant le chargement des contenus réduit la perception du temps d'attente.
-#### Streaming et Suspense
-Pour éviter de bloquer l'affichage de la page entière en attendant les données, nous utilisons le **Streaming avec React Suspense**. Les parties critiques de l'interface (comme la barre de navigation) s'affichent instantanément, tandis que les flux de mèmes se chargent progressivement avec des états de squelette (**Skeletons**), offrant une sensation de rapidité et de fluidité à l'utilisateur.
-
-#### Gestion des médias côté client
-L'interface intègre une prévisualisation interactive pour les uploads. Avant même l'envoi au serveur, le client valide la taille et le type du fichier, et génère une URL temporaire pour afficher le média, permettant à l'utilisateur de recadrer ou de confirmer son choix instantanément.
 
 ### F.4 - SEO et Métadonnées avec Next.js
-
+Memegoat est optimisé pour les moteurs de recherche :
-Memegoat tire profit de la puissance de la **Metadata API** de Next.js pour assurer un référencement optimal et une présence sociale forte.
+- **Génération dynamique de métadonnées** : Chaque mème possède son propre titre, description et image OpenGraph générés dynamiquement via la fonction `generateMetadata`.
-
+- **Données structurées (JSON-LD)** : Intégration de schémas (ImageObject, VideoObject) pour aider les moteurs de recherche à indexer le contenu de manière sémantique et favoriser l'apparition dans les "rich snippets".
-#### Métadonnées statiques et dynamiques
-- **Statiques (layout.tsx)** : Définition des éléments globaux tels que le nom du site, le template de titre (`%s | MemeGoat`), les icônes (favicon, SVG coloré) et les paramètres de base d'OpenGraph.
-- **Dynamiques (generateMetadata)** : Pour les pages de contenu (mèmes) et les catégories, nous utilisons la fonction `generateMetadata`. Elle permet de récupérer les informations en base de données (titre du mème, description, slug) pour générer des balises uniques. Cela garantit que chaque mème partagé affiche son propre titre et sa propre image d'aperçu sur les réseaux sociaux.
-
-#### Optimisation OpenGraph et Twitter
-L'application configure finement les en-têtes `og:title`, `og:description` et `og:image`. L'utilisation d'images OpenGraph dynamiques permet de booster le taux de clic lors des partages sur des plateformes comme X (Twitter), LinkedIn ou Discord.
-
-#### Données structurées JSON-LD
-Pour faciliter le travail des moteurs de recherche, Memegoat injecte des scripts JSON-LD. Ces microdonnées informent les robots que le contenu est de type "ImageObject" ou "VideoObject", précisant l'auteur, la date de publication et les mots-clés associés, favorisant ainsi l'apparition dans les "rich snippets" de Google.
 
 ### F.5 - Accessibilité et Design Inclusif (A11Y)
+Le projet respecte les standards d'accessibilité :
+- **Composants Radix UI / Shadcn** : Utilisation de primitives accessibles respectant les spécifications WAI-ARIA (Gestion du Focus Trap, Navigation Clavier).
+- **Contraste et Navigation** : Respect des ratios de contraste WCAG et support complet de la navigation au clavier avec une gestion visible du focus.
+- **Sémantique HTML** : Utilisation rigoureuse des balises sémantiques (`<header>`, `<main>`, `<section>`) pour faciliter la navigation des lecteurs d'écran.
 
-L'accessibilité est intégrée dès la phase de maquettage et vérifiée tout au long de l'intégration.
+## 4.6 Déploiement et Infrastructure
-
-#### Composants Radix UI et WAI-ARIA
-Nous utilisons **Radix UI** pour les composants complexes (fenêtres modales, menus déroulants, accordéons). Ces composants "headless" gèrent toute la logique d'accessibilité :
-- Gestion du **Focus Trap** dans les modales.
-- Navigation par flèches clavier dans les menus.
-- Support natif des attributs ARIA (`aria-expanded`, `aria-controls`, etc.).
-
-#### Sémantique et Hiérarchie
-Le code HTML respecte une hiérarchie stricte des titres (`<h1>` à `<h6>`) et utilise des balises sémantiques (`<header>`, `<main>`, `<footer>`, `<section>`). Chaque image dispose d'un attribut `alt` explicite (ou `alt=""` pour les images décoratives), et les boutons ont des labels textuels ou des `aria-label` lorsqu'ils ne contiennent que des icônes.
-
-#### Tests d'accessibilité
-Pendant le développement, nous utilisons des outils comme **Lighthouse** et des extensions de type **Axe DevTools** pour identifier et corriger les obstacles à la navigation (contrastes insuffisants, cibles de clic trop petites, erreurs de sémantique).

     *   **Définition :** Contraction du mot "Accessibility" (11 lettres entre le A et le Y).
     *   **Explication :** Désigne l'ensemble des pratiques visant à rendre les services numériques utilisables par tous, y compris les personnes en situation de handicap (visuel, moteur, auditif, etc.). Dans Memegoat, cela se traduit par l'utilisation de composants sémantiques et le respect des normes WCAG.
 
+*   **ANSSI (Agence Nationale de la Sécurité des Systèmes d'Information) :**
+    *   **Définition :** Autorité nationale française en matière de cybersécurité.
+    *   **Explication :** Memegoat suit les recommandations de l'ANSSI pour le choix des algorithmes de hachage (Argon2id) et la configuration des protocoles TLS afin de garantir un niveau de sécurité étatique.
+
 *   **API (Interface de Programmation d'Application) :**
     *   **Définition :** Ensemble de règles et de protocoles permettant à deux logiciels de communiquer entre eux.
     *   **Explication :** Dans ce projet, l'API NestJS sert de pont entre le frontend (Next.js) et les données stockées en base. Elle expose des points d'accès (endpoints) sécurisés pour récupérer ou modifier les mèmes et les profils utilisateurs.

     *   **Définition :** Chaîne d'outils (toolchain) ultra-rapide pour le web.
     *   **Explication :** Il remplace ESLint et Prettier pour assurer le formatage et le linting du code. Son utilisation garantit une base de code propre, homogène et performante, tout en accélérant le workflow de développement.
 
+*   **Blind Indexing (Indexation Aveugle) :**
+    *   **Définition :** Technique permettant de rechercher des données chiffrées sans les déchiffrer.
+    *   **Explication :** Utilisé pour l'unicité des emails. On stocke un hash de l'email à côté de l'email chiffré PGP. Cela permet de vérifier si un email existe déjà en base sans avoir à déchiffrer tous les emails de la table.
+
 *   **CSP (Content Security Policy) :**
     *   **Définition :** Couche de sécurité supplémentaire qui aide à détecter et atténuer certains types d'attaques, comme le XSS.
     *   **Explication :** En définissant quelles sources de contenu (scripts, images) sont autorisées, Memegoat empêche l'exécution de code malveillant injecté par un tiers.
