Global Validation

Acerca de

Global Validation provides comprehensive guidance for implementing defensive programming practices within n8n node development. It standardizes how input parameters are checked, sanitized, and handled, focusing on server-side security, early failure patterns, and clear error reporting. This skill is essential for developers looking to prevent injection attacks and ensure consistent data quality by applying rigorous validation rules to node parameters, business logic, and external data entry points.
