Best Practices

1. Update Handling

   • Process updates asynchronously
   • Implement proper error boundaries
   • Log all update types

2. State Management

   • Maintain minimal state
   • Use TTL for cached data
   • Clean up old conversations

3. Performance

   • Batch similar operations
   • Use webhooks in production
   • Implement connection pooling

4. Error Recovery

   • Implement exponential backoff
   • Log errors with context
   • Provide fallback responses

5. Security

   • Validate all inputs
   • Sanitize user content
   • Implement rate limiting
