Best Practices

Security Best Practices

1. Protect Your Application Secret

• Store your APP_SECRET securely on your server using secure key management systems
• Use environment variables to manage sensitive information like APP_ID and APP_SECRET
• Implement secure rotation policies for your secrets
• Consider using secret management services like AWS Secrets Manager or HashiCorp Vault

2. Use HTTPS

Always use HTTPS for all communications to ensure end-to-end encryption:

• Configure SSL/TLS certificates properly
• Enable HSTS (HTTP Strict Transport Security)
• Regularly update your SSL certificates
• Use modern TLS versions (1.2 or higher)

3. Implement Rate Limiting

Protect your API endpoints with comprehensive rate limiting:

• Set appropriate request limits per IP/user
• Implement exponential backoff for repeated requests
• Use token bucket or sliding window algorithms
• Monitor and log rate limit violations

Implementation Best Practices

1. Implement Proper Error Handling

Build robust error handling mechanisms:

try {
  // Your verification logic
} catch (error) {
  if (error.name === 'ValidationError') {
    // Handle validation errors
  } else if (error.name === 'NetworkError') {
    // Handle network issues
  } else {
    // Handle unexpected errors
  }
}

2. Keep the SDK Updated

Update the SDK using npm:

npm update @reclaimprotocol/js-sdk

Set up automated dependency updates using tools like Dependabot or Renovate.

Performance Best Practices

1. Optimize API Calls

Implement efficient API usage patterns:

• Cache frequently accessed data
• Batch related API calls where possible
• Implement retry mechanisms with exponential backoff
• Use connection pooling for database operations

2. Use Asynchronous Operations

Leverage asynchronous programming effectively:

• Implement Promise-based operations
• Use async/await for better readability
• Handle concurrent operations efficiently
• Avoid blocking operations in critical paths

Testing and Monitoring

1. Implement Comprehensive Testing

Establish a robust testing strategy:

• Unit tests for individual components
• Integration tests for SDK interactions
• End-to-end tests for complete workflows
• Performance tests for load handling
• Security tests for vulnerability checking

2. Monitor SDK Usage

Implement comprehensive monitoring:

• Track key performance metrics
• Set up alerting for critical issues
• Monitor error rates and latency
• Use logging for debugging and auditing

User Experience Best Practices

1. Provide Clear Instructions

Create an intuitive user experience:

• Use clear, concise language
• Provide step-by-step guidance
• Include progress indicators
• Offer contextual help where needed

2. Implement Graceful Fallbacks

Design resilient user flows:

• Provide clear error messages
• Offer retry options
• Implement offline capabilities where possible
• Create alternative verification paths

3. Optimize Loading States

Enhance perceived performance:

• Use skeleton screens for loading states
• Implement progressive loading
• Show meaningful progress indicators
• Provide estimated completion times
