-# React + TypeScript + Vite
+# Expria Frontend
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+Frontend SaaS pour la préparation au TCF Canada. SPA React + Vite, déploiement Cloudflare Pages.
 
-Currently, two official plugins are available:
+## Stack
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+React 19 · Vite 8 · TypeScript 6 · Tailwind 4 · React Router 7 · TanStack Query 5 · Supabase Auth · Vitest.
 
-## React Compiler
+Détails et versions : [`docs/adr/006-stack-versions-2026.md`](docs/adr/006-stack-versions-2026.md).
 
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+## Prérequis
 
-## Expanding the ESLint configuration
+- Node.js 22 LTS
+- npm 10+
 
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+## Installation
 
-```js
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
+```bash
+npm install
+cp .env.example .env
+# Remplir .env avec tes valeurs Supabase + URL backend
 ```
 
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+## Commandes
 
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
+| Commande | Rôle |
+|---|---|
+| `npm run dev` | Lance le serveur de dev Vite (HMR) |
+| `npm run build` | Build de production |
+| `npm run typecheck` | `tsc --noEmit` |
+| `npm run lint` | ESLint |
+| `npm run test` | Vitest (run unique) |
+| `npm run test:watch` | Vitest (watch mode) |
+| `npm run format` | Formate tout via Prettier |
+| `npm run format:check` | Vérifie le formatage sans écrire |
 
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {

-      },
-      // other options...
-    },
-  },
-])
