# Next Steps - Frontend Implementation

## ✅ Completed (Foundation Setup)

1. ✅ Project structure created
2. ✅ Core dependencies installed
3. ✅ API client setup (`lib/api/client.js`)
4. ✅ Auth API module (`lib/api/auth.js`)
5. ✅ Format utilities (`lib/utils/format.js`)
6. ✅ Constants (`lib/utils/constants.js`)
7. ✅ Auth Context (`contexts/AuthContext.jsx`)
8. ✅ Providers setup (`app/providers.jsx`)
9. ✅ Root layout updated with providers
10. ✅ Path aliases configured (`@/*`)

## 🎯 Next Immediate Steps

### 1. Create Environment File
```bash
cp .env.local.example .env.local
# Edit .env.local with your settings
```

### 2. Create UI Components (Priority)
- [ ] Button component
- [ ] Input component
- [ ] Card component
- [ ] Modal component
- [ ] Loading spinner

### 3. Create Layout Components
- [ ] Sidebar navigation
- [ ] Header with user menu
- [ ] Dashboard layout wrapper

### 4. Create Authentication Pages
- [ ] Login page (`app/(auth)/login/page.jsx`)
- [ ] Setup page (`app/(auth)/setup/page.jsx`)

### 5. Create Protected Routes
- [ ] Dashboard layout (`app/(dashboard)/layout.jsx`)
- [ ] Dashboard home page (`app/(dashboard)/page.jsx`)
- [ ] Auth middleware/guard

### 6. Create Additional API Modules
- [ ] Products API (`lib/api/products.js`)
- [ ] Sales API (`lib/api/sales.js`)
- [ ] Inventory API (`lib/api/inventory.js`)
- ... (one per backend module)

## 📝 Recommended Order of Implementation

1. **UI Components** → Build reusable base components
2. **Login Page** → Get authentication working
3. **Dashboard Layout** → Create main app structure
4. **Dashboard Home** → Show overview/stats
5. **POS Interface** → Core feature
6. **Products Management** → Essential CRUD
7. **Other Features** → Build out remaining modules

## 🚀 Quick Start Commands

```bash
# Start development server
npm run dev

# The app will run on http://localhost:3000
# Make sure backend is running on http://localhost:3000/api
```

## 📚 Key Files Created

- `lib/api/client.js` - Axios instance with interceptors
- `lib/api/auth.js` - Authentication API calls
- `contexts/AuthContext.jsx` - Auth state management
- `app/providers.jsx` - React Query & Auth providers
- `config/api.js` - API configuration & endpoints
- `lib/utils/format.js` - Formatting utilities
- `lib/utils/constants.js` - App constants

## 💡 Tips

- Use React Query for all API calls (data fetching)
- Use Auth Context for user state
- Follow the folder structure in FRONTEND_PLAN.md
- Keep components small and reusable
- Use Tailwind CSS for styling
- Test with backend API running
