## 🔄 Migration Steps

### Step 1: Move Files (Pick One)

**Option A - PowerShell Script:**
```powershell
.\migrate-files.ps1
```

**Option B - Manual:**
```bash
move App.tsx src\
move components src\
move utils src\
move styles src\
```

### Step 2: Install Dependencies

```bash
npm install
```

This installs ~50 packages (takes 2-3 minutes).

### Step 3: Update Imports in src/App.tsx

**Find and Replace in App.tsx:**

1. Change all component imports:
```typescript
// OLD
import { Layout } from './components/Layout';
import { Dashboard } from './components/Dashboard';
// ... all other component imports

// NEW
import { Layout } from '@/components/Layout';
import { Dashboard } from '@/components/Dashboard';
// ... use @/ for all imports
```

2. Fix sonner import:
```typescript
// OLD
import { toast } from 'sonner@2.0.3';

// NEW
import { toast } from 'sonner';
```

### Step 4: Update Component Files

In all files under `src/components/`, change relative imports:

```typescript
// OLD in any component file
import { Button } from './ui/button';
import { Card } from '../ui/card';

// NEW
import { Button } from '@/components/ui/button';
import { Card } from '@/components/ui/card';
```

### Step 5: Start Development Server

```bash
npm run dev
```

Visit: http://localhost:3000

---

## 🛠️ Available Commands

```bash
# Development
npm run dev              # Start dev server (port 3000)

# Build
npm run build            # Build for production
npm run preview          # Preview production build

# Code Quality
npm run lint             # Check for errors
npm run lint:fix         # Auto-fix errors
npm run format           # Format with Prettier
npm run type-check       # Check TypeScript types
```

---

## ✨ New Features You Get

### 1. **Path Aliases** - Cleaner Imports
```typescript
// Before
import { Button } from '../../../components/ui/button';

// After
import { Button } from '@/components/ui/button';
```

### 2. **TypeScript Types** - Better IntelliSense
```typescript
import type { Request, DealerInfo } from '@/types';

const request: Request = { /* auto-complete works! */ };
```

### 3. **Code Quality** - Auto-fix on Save
- ESLint catches bugs
- Prettier formats code
- TypeScript ensures type safety

### 4. **Fast Development**
- Hot Module Replacement (HMR)
- Instant updates on file save
- Optimized build with code splitting

---

## 🆘 Common Issues & Fixes

### Issue 1: "Cannot find module '@/...'"

**Fix:**
```bash
# Restart TypeScript server
# In VS Code: Ctrl+Shift+P → "TypeScript: Restart TS Server"
```

### Issue 2: "Module not found: sonner@2.0.3"

**Fix in src/App.tsx:**
```typescript
// Change this:
import { toast } from 'sonner@2.0.3';

// To this:
import { toast } from 'sonner';
```

### Issue 3: Tailwind classes not working

**Fix:**
1. Ensure `src/main.tsx` has: `import './styles/globals.css';`
2. Restart dev server: `Ctrl+C` then `npm run dev`

### Issue 4: Build fails

**Fix:**
```bash
npm run type-check   # See what TypeScript errors exist
npm run lint         # See what ESLint errors exist
```
