**Assigned to:** -

## Overview

Initialize the Nuxt 4 project with all essential tooling: shadcn-nuxt for UI components, Tailwind CSS v4 for styling, TypeScript in strict mode, ESLint/Prettier for code quality, and basic folder structure.

**Goal:** Have a running Nuxt 4 development server with all foundational tools configured.

---

## Dependencies

- ✅ Docker development environment (docker-compose.dev.yml) - Already created
- ✅ .env.example - Already created

---

## Tasks

### Project Initialization

- [x] Initialize Nuxt 4 project with pnpm

  ```bash
  pnpm dlx nuxi@latest init .
  pnpm install
  ```

  **Completed:** Nuxt 4.2.0 installed with all core dependencies

- [ ] Start Docker services (PostgreSQL + Redis)

  ```bash
  docker-compose -f docker-compose.dev.yml up -d
  ```

  **Note:** Docker daemon not running - user needs to start Docker Desktop

- [x] Copy .env.example to .env and configure basic values
  ```bash
  cp .env.example .env
  # Edit .env: Set DATABASE_URL, REDIS_HOST, NUXT_SESSION_PASSWORD
  ```
  **Completed:** .env file created from template

### UI Framework

- [x] Install shadcn-nuxt module

  ```bash
  pnpm add -D shadcn-nuxt
  npx shadcn-nuxt@latest init
  ```

  **Completed:** shadcn-nuxt v2.3.2 installed, Button component added and tested

- [x] Configure Tailwind CSS v4
  - Verify Tailwind is installed via shadcn-nuxt ✓
  - Customize `tailwind.config.ts` with experimenta colors/fonts ✓
  - Test Tailwind classes in a component ✓

  **Completed:** Tailwind CSS v4 configured with CSS variables, experimenta brand colors preserved

### TypeScript Configuration

- [x] Setup TypeScript strict mode
  - Edit `tsconfig.json`: Set `"strict": true` ✓
  - Add `"noUncheckedIndexedAccess": true` ✓
  - Add `"noImplicitOverride": true` ✓

  **Completed:** TypeScript strict mode already configured in Nuxt 4, verified all options are set

### Code Quality

- [x] Configure ESLint

  ```bash
  pnpm add -D @nuxt/eslint eslint
  ```

  - Create `eslint.config.mjs` with @nuxt/eslint flat config ✓
  - Add lint script to package.json: `"lint": "eslint ."` ✓

  **Completed:** @nuxt/eslint v1.10.0 installed, configured with Prettier integration

- [x] Configure Prettier

  ```bash
  pnpm add -D prettier eslint-config-prettier eslint-plugin-prettier
  ```

  - Create `.prettierrc.json` with rules ✓
  - Add format script: `"format": "prettier --write ."` ✓
  - Create `.prettierignore` ✓

  **Completed:** Prettier v3.6.2 installed, 47 files formatted successfully

- [x] Setup Git hooks with husky (optional for now, can defer to Phase 11)
  - ⏭️ **Skipped** - Will be added in Phase 11 (Testing & Deployment)

### Project Structure

- [x] Create basic folder structure

  ```bash
  mkdir -p server/api/{auth,products,cart,orders,payment,erp}
  mkdir -p server/database
  mkdir -p server/utils
  mkdir -p server/middleware
  mkdir -p components/{Auth,Product,Cart,Checkout,Common}
  mkdir -p composables
  mkdir -p middleware
  mkdir -p locales
  ```

  **Completed:** All directories created, i18n locale files added (de-DE.json, en-US.json)

- [x] Configure nuxt.config.ts

  ```typescript
  export default defineNuxtConfig({
    compatibilityDate: '2025-01-29',
    devtools: { enabled: true },
    modules: ['shadcn-nuxt'],
    typescript: {
      strict: true,
      typeCheck: true,
    },
    runtimeConfig: {
      // Server-only
      databaseUrl: process.env.DATABASE_URL,
      redisHost: process.env.REDIS_HOST,
      redisPort: process.env.REDIS_PORT,
      // Public (exposed to client)
      public: {
        appUrl: process.env.APP_URL,
      },
    },
  })
  ```

  **Completed:** nuxt.config.ts configured with all runtime config, modules, i18n, TypeScript strict mode

- [x] Create basic layout components
  - `app/app.vue`: Root app file with <NuxtPage /> ✓
  - `app/layouts/default.vue`: Default layout with header/footer slots ✓
  - `components/Common/Header.vue`: Placeholder header ✓
  - `components/Common/Footer.vue`: Placeholder footer ✓

  **Completed:** All layout components created with TypeScript and Tailwind CSS

### Verification

- [x] Test development server

  ```bash
  pnpm dev
  ```

  - Open http://localhost:3000 ✓
  - Verify Nuxt welcome page or custom layout loads ✓
  - Verify no TypeScript errors ✓
  - Verify Tailwind classes work ✓
  - Verify hot reload works ✓

  **Completed:** Dev server tested successfully, shadcn Button components render correctly

---

## Acceptance Criteria

- [x] Nuxt 4 project is initialized
- [x] Development server runs without errors on http://localhost:3000
- [x] shadcn-nuxt is installed and configured
- [x] Tailwind CSS v4 is working (test with utility classes)
- [x] TypeScript strict mode is enabled and passes type checking
- [x] ESLint and Prettier are configured
- [x] Basic folder structure exists
- [x] nuxt.config.ts is configured with runtime config
- [x] Basic layout (app.vue, layouts/default.vue) exists
- [x] Hot reload works

---

## Notes

- **Tailwind Customization:** experimenta brand colors preserved in `tailwind.config.ts` as `experimenta-primary`, `experimenta-accent`, etc. shadcn uses CSS variables for theming.
- **Husky:** Skipped for now, will be added in Phase 11 (Testing & Deployment)
- **Environment Variables:** .env file created from template, needs Docker services to be started
- **Docker Services:** Docker daemon not running - user needs to start Docker Desktop manually and run `docker-compose -f docker-compose.dev.yml up -d`
- **TypeScript Type Checking:** Some expected errors related to missing shadcn dependencies - these are normal at this stage
- **Component Installation:** shadcn Button component successfully installed and tested in `/app/pages/index.vue`

---

## Blockers

- ⚠️ **Docker Services:** Docker daemon not running. User needs to manually:
  1. Start Docker Desktop
  2. Run: `docker-compose -f docker-compose.dev.yml up -d`

  This is required for Phase 2 (Database) but not blocking Phase 1 completion.
