• Request logging and analytics

• Performance metrics dashboard

🔧 Configuration Examples

Basic Mock API

{
  "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

{
  "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

// 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

# 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
