## ⚙️ Configuration

### Environment Variables

```bash
# .env file
NODE_ENV=development
LOGIN_USERNAME=admin
LOGIN_PASSWORD_HASH=your_generated_hash
DATABASE_URL=mysql://user:password@localhost:3306/dbname

# Optional
PORT=3000
NEXT_PUBLIC_API_URL=http://localhost:3000
```

### Database Configuration

```javascript
// mysql.config.js
module.exports = {
  mysqlOptions: {
    host: process.env.DB_HOST || 'localhost',
    port: process.env.DB_PORT || 3306,
    user: process.env.DB_USER || 'root',
    password: process.env.DB_PASSWORD || '',
    database: process.env.DB_NAME || 'nsgm_db'
  }
}
```

## 🔒 Security Setup

### Password Generation

```bash
# Generate secure hash
npm run generate-password your-secure-password

# Add to .env file
LOGIN_PASSWORD_HASH=your_generated_hash_here
```

### CSRF Protection

NSGM CLI includes built-in CSRF protection:

```javascript
// Automatic CSRF token generation
app.use(csrfProtection)

// Custom CSP headers
app.use(createCSPMiddleware({
  directives: {
    defaultSrc: ["'self'"],
    styleSrc: ["'self'", "'unsafe-inline'"],
    scriptSrc: ["'self'"]
  }
}))
```

## 🧪 Testing

```bash
# Run all tests
npm test

# Watch mode
npm run test:watch

# Coverage report
npm run test:coverage

# Lint code
npm run lint

# Format code
npm run format
```

## 📚 Examples

### Creating a Blog System

```bash
# 1. Initialize project
nsgm init my-blog

# 2. Create controllers
cd my-blog
nsgm create post
nsgm create category
nsgm create user

# 3. Start development
npm run dev
```

### Adding Custom API Endpoint

```javascript
// server/apis/custom.js
const express = require('express')
const router = express.Router()

router.get('/stats', (req, res) => {
  res.json({
    totalPosts: 42,
    totalUsers: 15,
    lastUpdate: new Date()
  })
})

module.exports = router
```

### Custom GraphQL Schema

```javascript
// server/modules/blog/schema.js
module.exports = {
  query: `
    posts(limit: Int, offset: Int): [Post]
    post(id: ID!): Post
  `,
  mutation: `
    createPost(title: String!, content: String!): Post
    updatePost(id: ID!, title: String, content: String): Post
    deletePost(id: ID!): Boolean
  `,
  type: `
    type Post {
      id: ID!
      title: String!
      content: String!
      createdAt: Date!
      updatedAt: Date!
    }
  `
}
```

## 🐛 Troubleshooting

### Common Issues

**Port already in use**
```bash
# Kill process on port 3000
lsof -ti:3000 | xargs kill -9

# Or use different port
PORT=3001 npm run dev
```

**Database connection failed**
```bash
# Check MySQL service
sudo systemctl status mysql

# Verify credentials in .env
cat .env | grep DB_
```

**Permission denied**
```bash
# Fix npm permissions
sudo chown -R $(whoami) ~/.npm

# Or use different install location
npm config set prefix '~/.local'
```
