```

## Getting Started

### Prerequisites

- Node.js 18+ and npm
- Backend API running (see API section)

### Installation

```bash
# Install dependencies
npm install

# Set up environment variables
cp .env.local.example .env.local
# Edit .env.local with your API URL
```

### Environment Variables

Create a `.env.local` file:

```env
NEXT_PUBLIC_API_URL=http://localhost:8000/api
```

For production, create `.env.production`:

```env
NEXT_PUBLIC_API_URL=https://api.portfolio-host.com/api
```

### Development

```bash
# Start development server
npm run dev
```

Visit [http://localhost:3000](http://localhost:3000)

### Build

```bash
# Build for production
npm run build

# Start production server
npm start
```

### Docker Deployment

```bash
# Build Docker image
docker build -t hosting-frontend .

# Run container
docker run -p 3000:3000 hosting-frontend
```

## API Integration

The application integrates with a backend API for:

### Authentication Endpoints
- `POST /auth/register` - User registration
- `POST /auth/login` - User login
- `POST /auth/logout` - Logout
- `GET /auth/user` - Get current user
- `POST /auth/refresh` - Refresh token

### Portfolio Endpoints
- `GET /portfolios` - List user's portfolios
- `POST /portfolios` - Create new portfolio
- `POST /portfolios/{id}/upload` - Upload ZIP file
- `POST /portfolios/{id}/deploy` - Deploy portfolio
- `GET /portfolio/random` - Get random portfolio

### API Response Format

All API responses follow this structure:

```typescript
{
  success: boolean;
  data?: T;
  message?: string;
  errors?: any;
}
```

## Key Components

### Authentication Flow

1. User logs in via `/login`
2. API returns JWT token
3. Token stored in localStorage
4. AuthContext provides auth state globally
5. Middleware protects `/dashboard/*` routes
6. API client automatically injects Bearer token

### Portfolio Management Flow

1. User creates portfolio (name + domain)
2. Upload ZIP file containing portfolio files
3. Deploy portfolio to make it live
4. Status indicators show portfolio state:
   - **Pending Payment**: Not yet active
   - **Pending Upload**: Active but no files
   - **Uploaded**: Ready to deploy

## Code Style & Conventions

### File Naming
- Components: `PascalCase.tsx`
- Utilities: `kebab-case.ts`
- Pages: Next.js conventions (`page.tsx`, `layout.tsx`)

### Component Patterns
- Use `'use client'` directive for client components
- Server components by default
- Colocate styles with components

### State Management
- Global auth state: `AuthContext`
- Component state: `useState`
- Form state: React Hook Form

### API Calls
- Use `apiClient` from `lib/api-client.ts`
- Wrap in try/catch
- Handle loading and error states

## Migration from Angular

This project was migrated from Angular 20 to Next.js 15. Key changes:

- **Framework**: Angular → Next.js + React
- **Routing**: Angular Router → Next.js App Router
- **State**: RxJS → React Context API
- **Forms**: Angular Reactive Forms → React Hook Form
- **HTTP**: Angular HttpClient → Fetch API

The Angular code has been backed up to `/angular-backup` for reference.

## Deployment

### Production Build

The production build uses Next.js standalone output for optimal performance:

```bash
npm run build
```

Output is in `.next/standalone/`

### Environment Configuration

- Development: `.env.local`
- Production: `.env.production`
- Staging: `.env.staging`

### Docker

The included `Dockerfile` creates an optimized production image:

```dockerfile
# Build and run
docker build -t portfolio-frontend .
docker run -p 3000:3000 -e NEXT_PUBLIC_API_URL=https://api.example.com portfolio-frontend
```

## Troubleshooting

### Build Errors

**Issue**: Tailwind CSS errors
```bash
# Ensure @tailwindcss/postcss is installed
npm install @tailwindcss/postcss
```

**Issue**: TypeScript errors
```bash
# Regenerate types
rm -rf .next
npm run build
```

### Runtime Errors

**Issue**: API connection failed
- Check `NEXT_PUBLIC_API_URL` in `.env.local`
- Verify backend API is running
- Check CORS configuration on backend

**Issue**: Authentication not working
- Check localStorage for `auth_token`
- Verify JWT token format
- Check middleware configuration
