### 🔧 CLI Integration

```bash
# Start mock server
mockoon start --data ./mocks.json --port 3000

# Export configuration
mockoon export --format json --output ./export.json

# Import existing mocks
mockoon import --source ./import.json
```

### 📊 Performance Testing

* **Response delays** simulation
* **Load testing** capabilities
* **Request logging** and analytics
* **Performance metrics** dashboard

## 🔧 Configuration Examples

### Basic Mock API

```json
{
  "uuid": "user-api-mock",
  "method": "GET",
  "path": "/api/users",
  "responses": [
    {
      "statusCode": 200,
      "headers": {
        "Content-Type": "application/json"
      },
      "body": "{{#repeat 3}}{\"id\":{{index}}, \"name\":\"{{faker 'name.firstName'}}\", \"email\":\"{{faker 'internet.email'}}\"}{{/repeat}}"
    }
  ]
}
```

### Advanced Rules Example

```json
{
  "uuid": "conditional-api",
  "method": "GET",
  "path": "/api/data",
  "rules": [
    {
      "target": "header",
      "modifier": "exists",
      "value": "Authorization",
      "operator": "and",
      "invert": false
    }
  ],
  "responses": [
    {
      "statusCode": 200,
      "body": "{\"message\": \"Authenticated data\"}"
    },
    {
      "statusCode": 401,
      "body": "{\"error\": \"Unauthorized\"}"
    }
  ]
}
```

## 🌐 Integration Patterns

### Frontend Development

* **Rapid prototyping** without backend dependency
* **API contract** testing before implementation
* **Offline development** capabilities
* **Edge case** simulation

### Testing Workflows

* **Unit testing** with predictable responses
* **Integration testing** with controlled APIs
* **E2E testing** scenarios
* **Performance testing** with realistic data

### Team Collaboration

* **Shared mock environments**
* **Version control** of API specifications
* **Documentation generation**
* **Developer handoff** tools

## 🔍 Best Practices

### Design Principles

* **Realistic data** generation
* **Consistent API contracts**
* **Environment isolation**
* **Documentation maintenance**

### Performance Optimization

* **Efficient rule evaluation**
* **Memory usage** management
* **Response time** optimization
* **Concurrent request** handling

## 📚 Advanced Topics

### Custom Data Helpers

```javascript
// Custom helper functions
function customRandom(min, max) {
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

// Usage in templates
{{customRandom 1 100}}
```

### Proxy Configuration

* **Request forwarding** to real APIs
* **Response modification** on the fly
* **Fallback strategies**
* **Error handling**

### Automation Scripts

```bash
# Automated testing workflow
npm run test:api -- --mock-server=http://localhost:3000

# CI/CD integration
mockoon start --data ./tests/mocks.json &
npm run test:integration
mockoon stop
```

## 🚀 Troubleshooting

### Common Issues

* **Port conflicts** resolution
* **CORS** configuration
* **SSL certificate** setup
* **Memory** optimization

### Debug Mode

* **Request logging** enablement
* **Response inspection** tools
* **Performance monitoring**
* **Error diagnostics**

## 🔧 Status
