Nodes Programmatic Patterns

Acerca de

Provides comprehensive guidance for building n8n nodes using a programmatic approach, offering full control over execution flows and data transformations. This skill is essential for developers creating complex integrations that require custom API request handling, cursor-based pagination, or sophisticated webhook and polling triggers. It ensures best practices are followed—such as preventing direct input modification and implementing robust error handling—making it ideal for developing high-performance, production-grade automation components within the n8n ecosystem.
