feat: add runtime language selector in header (EN/FR toggle)
- Add LanguageSelector component with globe icon + cycle button - Refactor i18n to support reactive locale switching via useSyncExternalStore - Locale priority: localStorage > VITE_LOCALE > navigator.language > 'en' - All components now use useT() hook for reactive re-rendering on locale change - Persists choice to localStorage (key: pinchchat-locale) - No page reload needed — instant switch

- **Priority:** medium
|
||||
- **Status:** done
|
||||
- **Completed:** 2026-02-11 — commit `99b7db9`
|
||||
- **Description:** Ajouter le support i18n (internationalisation) — le projet open-source est en anglais, mais le deploy perso de Nicolas doit rester en français. Soit via une config `.env` (ex: `VITE_LOCALE=fr`), soit via un système de traduction léger. Les strings UI (placeholder input, bouton envoyer, statut connexion, etc.) doivent être configurables.

## Item #4
|
||||
- **Date:** 2026-02-11
|
||||
- **Priority:** high
|
||||
- **Status:** done
|
||||
- **Completed:** 2026-02-11 — commit `36f9480`
|
||||
- **Description:** Supprimer le token du build — implémenter un écran de login au runtime
|
||||
- Au premier lancement (ou si pas de credentials en localStorage), afficher un écran de connexion avec :
|
||||
- Champ "Gateway URL" (ex: `ws://192.168.1.14:18789`)
|
||||
- Champ "Token" (password field)
|
||||
- Bouton "Connect"
|
||||
- Stocker les credentials en `localStorage` (pas dans le bundle JS)
|
||||
- Supprimer `VITE_GATEWAY_TOKEN` du `.env.example` et du code
|
||||
- Garder `VITE_GATEWAY_WS_URL` uniquement comme valeur par défaut optionnelle pour pré-remplir le champ URL
|
||||
- Ajouter un bouton "Disconnect" / "Logout" dans le header qui clear le localStorage et revient à l'écran de login
|
||||
- L'écran de login doit suivre le même thème dark neon que le reste de l'app
|
||||
- ⚠️ Après ce changement, le deploy perso (`~/marlbot-chat/.env`) n'a plus besoin de `VITE_GATEWAY_TOKEN` — l'utilisateur entrera le token via l'UI
|
||||
- **Description:** Runtime login screen
|
||||
|
||||
## Item #5
|
||||
- **Date:** 2026-02-11
|
||||
- **Priority:** high
|
||||
- **Status:** pending
|
||||
- **Description:** Ajouter un sélecteur de langue dans l'UI
|
||||
- Un petit toggle/dropdown dans le header ou le login screen pour choisir la langue (EN/FR)
|
||||
- Stocker le choix en localStorage (priorité sur `VITE_LOCALE` et le locale du navigateur)
|
||||
- Ordre de priorité : localStorage > VITE_LOCALE > navigator.language > 'en'
|
||||
- Le changement doit être immédiat (pas de reload nécessaire si possible, sinon reload OK)
|
||||
- Garder ça minimaliste — juste un petit 🌐 ou drapeau dans le header
|
||||
|
||||
## Item #6
|
||||
- **Date:** 2026-02-11
|
||||
- **Priority:** high
|
||||
- **Status:** pending
|
||||
- **Description:** Installation simplifiée — Docker + oneliner
|
||||
- **Dockerfile** : image légère (nginx:alpine ou similar) qui sert le build statique. Multi-stage : node pour build, nginx pour serve. Pas de secrets dans l'image (tout est runtime via le login screen).
|
||||
- **docker-compose.yml** : exemple simple avec juste le container PinchChat
|
||||
- **Publier l'image sur ghcr.io** : `ghcr.io/marlburrow/pinchchat:latest` — le CI GitHub Actions doit build & push l'image à chaque push sur main
|
||||
- **Oneliner** : `docker run -p 3000:80 ghcr.io/marlburrow/pinchchat:latest` dans le README
|
||||
- Alternative sans Docker : `npx pinchchat` ou un script curl qui télécharge le dernier release (build statique) et lance un serveur
|
||||
- Mettre à jour le README avec les nouvelles méthodes d'installation
